A CONVERSATION REGARDING THE ENERGY CONSUMPTION OF ELECTRIC HOT WATER HEATERS Water heating is the second largest use of energy in homes accounting for 17% to 29% of residential energy consumption. Two separate studies published by the U.S. DEPARTMENT OF ENERGY¹, in September 2009 & 2010, supports a major need for homeowners and businesses to address the high energy use, as well as the efficiency, of hot water heating whether using electric, natural or propane gas models. The AQUA SMART™ system was developed as a RETROFIT SYSTEM for previously installed electric hot water heaters or newly installed electric hot water heaters that do not include factory-installed, energy saving features. The AQUA SMART™ system can save 20% and more of the energy usage of an electric hot water heater, however, these savings depend on the user’s proactive operation of the system. No savings will be realized unless the user activates the available MODES or PROGRAMS on the system’s Transmitter and monitors the hot water heaters electrical usage. The AQUA SMART™ Receiver’s wiring is integrated into the incoming power supply to the electric hot water heater and mounts on top of the water heater and operates on 208-240VAC. Once installed, the user should not have to monitor the Receiver component. The operation of the AQUA SMART™ system is controlled by the Remote Transmitter which features 4 operating MODES and operates, “wirelessly”, from up to 100 feet from the Receiver. · The ON mode is activated when the user wants to operate the hot water heater by-passing the other operating MODES in the AQUA SMART™ system. · In the AWAY mode, user can “set-back” the water heater temperature to operate between 75°F and 85°F when plans call for being away for 2 - 7 days. · User can also enter the VACATION mode which operates the water heater between 40°F and 50°F when the user plans to be away from the home for longer periods of time. · In the PROGRAM mode, the user can enter daily time/temperature settings to fit user’s lifestyle or defer to the settings in the factory-set program. Following the INSTALLATION instructions for mounting of the AQUA SMART™ system on the hot water heater and understanding, the AQUA SMART™ OPERATING INSTRUCTIONS, will provide for the maximum in ENERGY SAVINGS. ¹ Energy Star Water Heater Profiles- September 2009 & 2010. 3.
The AQUA SMART™ system was developed to allow the homeowner to reduce electrical power consumption and conserve energy when the homeowner is away from the home for short or extended periods of time. With the AQUA SMART™ system, the user can control the temperatures of the hot water, without having to go to the water heater, remove the water heater’s access panels, and manually adjust the water heaters “on-board” thermostats. CONSUMER INFORMATION: The AQUA SMART™ system should be installed in accordance with the local electrical codes. In the absence of such codes, then follow the National Electrical Code (NEC), NFPA 70. The AQUA SMART™ system includes a 30 amp, BY-PASS breaker allowing the user to override the system. (See page 16). TECHNICAL INFORMATION CONSUMER RESPONSIBILITIES: This manual has been prepared to guide you through the proper installation, operation and maintenance of the AQUA SMART™ system. We urge you to read all the instructions relating to the installation and operation of this energy saving device. It is imperative that the user become proactive with the programming and activation of the energy-saving MODES to maximize the energy savings. AQUA SMART, INC. and its manufacturing entities will not be liable for any damages caused by the improper installation and operation of this device. UNDERSTANDING THE ADVANTAGES OF SETTING THE MODES OF OPERATION OF THE AQUA SMART™ “WIRELESS” SYSTEM WILL SAVE ENERGY COSTS THROUGHOUT THE LIFE OF THE WATER HEATER. 4. · 3-WIRE – 208-240 VOLT WIRING: The use of 208-240 volt wiring for residential homes is necessary for powering larger appliances such as water heaters, furnaces and air conditioners. 208-240 volt wiring for a hot water heater relies on two separate "hot wires", each carrying 110-120 volts of current and a "ground wire" which may be a bare copper wire or an insulated wire, green in color. The 2 "hot wires" complete the 208-240 volt circuit, one being positively charged, the other being negatively charged. Each wire delivers electricity to the hot water heater by alternating polarities and doubling the current to the water heater. The wiring to the water heater must be connected to a breaker, rated at a maximum of 30 amps, or meet the ampere requirements for the water heater that the AQUA SMART™ is to be installed on. The bare copper or green ground wire is attached to a grounding screw at the junction box on the water heater. The AQUA SMART system is designed to be installed on electric, hot water heaters with current ratings up to 30 amps or less with wattage ratings from 3000 watts to 6000 watts. · WATER HEATER INSTALLATION VIDEOS: While the AQUA SMART™ system is designed to be retrofitted to existing electric hot water heaters, it can also be installed on new water heaters that do not have factory-installed, energy saver features included. A review of a water heater installation video can be found on the web at: www.hotwater101.com which is very instructive. You may also want to visit website www.waterheatertimer.com for other technical data for installing and maintaining electric hot water heaters. We strongly recommend that you visit the AQUA SMART™ website at: www.aquaenergysaver.com to view an installation/ instruction video for installing the AQUA SMART™ system. · Electric Drill with 1/8” bit · ¼” nut driver/adjustable wrench · Wire Cutters · Straight blade screwdriver · Philips head screwdriver · Punch or Nail · Circuit tester or voltmeter 5. IMPORTANT: If you lack the necessary skills or understanding of the wiring of a 208-240V electric hot water heater, or you have difficulty or hesitation following these instructions, you should not proceed with this installation and should contact a qualified electrician or plumber to perform the installation of the AQUA SMART™ system. The AQUA SMART™ system is designed to be installed on electric hot water heaters with current ratings up to 30 amps. CONSUMER INFORMATION TECHNICAL INFORMATION When installing the AQUA SMART™ system, we strongly recommend you closely follow the instructions in this manual. TOOLS REQUIRED
SECTION 1 The AQUA SMART™ system is an energy saving device that retrofits on any 208-240 volt electric hot water heater. The system consists of the Receiver which mounts on top of the electric hot water heater. The Receiver is wired into the water heater’s junction box on top of the water heater. The Receiver includes 2-way signaling software that allows the Receiver and Transmitter to communicate with each other, confirming signals have been received by each other, as illustrated by an ICON on the transmitter’s LCD. The AQUA SMART™ system includes a Wireless, Remote Control Transmitter that signals the Receiver to operate in one of FOUR modes: ON, AWAY, VACATION or PROGRAM. The system operates on one of 1,048,576, unique security codes that are programmed into the transmitter at the factory. The Transmitter’s security code must be matched to the Receiver upon INITIAL SET-UP. The operating distance of the AQUA SMART™ system can be up to100 feet depending on any obstructions and/ or electrical or metallic interference between the Receiver and Transmitter. A test to verify the communication/operating distance is discussed in a later section. See pages (18-19). WATER TEMPERATURE READING FOR “BALANCING” PROCEDURE In the TRANSMITTER package, you will find a small thermometer strip you will use later in the “BALANCING” programming procedure. (See pages 23-24 for a detailed explanation of this procedure). The “BALANCING” programming is EXTREMELY important to the proper set up of the transmitter and operation of the AQUA SMART™ system. We recommend you proceed with the above step NOW so that the HOT water pipe will cool down before the “BALANCING” number is entered into the Transmitter. (See pages 23-24 for the BALANCING procedure). Draw a small glass of HOT water from a faucet that the water heater supplies and drop the thermometer strip into the water. Write down the mid-temperature reading from the strip. Save for later use when performing the “BALANCING” procedure on the Transmitter. (See Set-Up pages 23-24). 6. INSTALLATION INSTRUCTIONS – (continued) A. Shut off the electrical power to the hot water heater at the breaker panel, fuse box or power switch near the water heater. B. Remove the junction box cover(s) on top of the water heater. Use ¼” nut driver, screwdriver or wrench to remove screws. C. Check that power has been disconnected with a circuit tester or volt meter. Verify that the power has been disconnected, with a voltmeter or circuit tester, testing other incoming “HOT” wires. 7. INSTALLATION INSTRUCTIONS FIRST - SHUT OFF POWER TO HOT WATER HEATER SECOND - EXPOSE & TEST WIRES IN JUNCTION BOX IMPORTANT: If you lack the necessary skills or understanding of the wiring of a 208-240V electric hot water heater, or you have difficulty or hesitation following these instructions, you should not proceed with this installation and should contact a qualified electrician or plumber to perform the installation of the AQUA SMART™ system.

1. Position the Receiver BASE over the junction box opening on top of the water heater. Mark the position of the 4 mounting holes (on the BASE) to top of the water heater with a punch or nail. NOTE: Pull water heater wires thru the bottom opening on the BASE of Receiver. IMPORTANT: Be sure BASE completely covers junction box opening on top of water heater. If necessary, replace one of the junction box cover plates to close any gap or opening between the water heater junction box and the area around the Receiver BASE. 2. Drill 4 ea. - 1/8” holes through the top metal jacket on water heater. Only drill through the thin metal jacket. 3. Drill a 1/8” hole through the bottom of the junction box to attach the GREEN GROUND wire. 4. Attach the short, GREEN, GROUND wire, from the hardware package, with one of the SMS from the hardware package to the bottom of the junction box. IMPORTANT: WATER HEATER MUST BE GROUNDED. 10. 10. 5.

WIRING CONNECTIONS ILLUSTRATED 12. WIRING DIAGRAM 13. AT THIS POINT, BEGIN ATTACHING THE WIRES FROM THE RECEIVER TO THE INCOMING POWER SUPPLY WIRES AND TO THE HOT WATER HEATER WIRES. EACH OF THE WIRES FROM THE RECEIVER ARE LABELED TO ASSIST MAKING PROPER CONNECTIONS TO THE OF INCOMING POWER, GROUND WIRES AND TO THE 2 WIRES COMING FROM THE HOT WATER HEATER IMPORTANT IMPORTANT IMPORTANT IT IS CRITICAL TO FOLLOW THESE WIRING CONNECTIONS FOR RELIABLE OPERATION OF THE AQUA SMART™ SYSTEM
Taped to the back of the receiver case is the THERMAL SENSOR which is to be attached to the HOT water pipe coming out of the hot water heater. The THERMAL SENSOR controls the operation of the AQUA SMART™ system. Prepare to attach the THERMAL SENSOR to the LOWEST point on the HOT water pipe coming out of the top of the water heater. (Usually the top of water heater is marked HOT or feel the pipe to be sure attachment is to the HOT water pipe). Locate the pipe clamp with bolt/nut, included in the hardware package. Unscrew the clamp bolt so that only a few threads remain in the bolt. Slide the head of the bolt to the side so that it releases from the clamp. Spread the clamp open and slip the clamp around the HOT water pipe. Tighten the clamp bolt being sure clamp is at the LOWEST POSITION on the HOT water pipe exiting the hot water heater. Do not tighten clamp to the pipe, yet. 14. Carefully, insert the THERMAL SENSOR head between the clamp and the HOT water pipe positioning the SENSOR head so that it is covered by the clamp and is snug against the HOT water pipe. Now tighten the bolt on the clamp so the THERMAL SENSOR head is covered by the rubber insulation and is snug against the HOT water pipe. Following the securing of the THERMAL SENSOR head, to the HOT water pipe, wrap the piece of foam insulation over the CLAMP & SENSOR and firmly attach with 2 wire ties. BE SURE TIES ARE INSTALLED SO THEY “CLICK -LOCK” (The foam insulation was packed in the shipping box.The wire ties are in the hardware package.) This step is necessary to minimalize the effects of any ambient temperature differences between the SENSOR head and the location of the water heater. The SENSOR head needs to be isolated from any external temperature influences which could have a thermal effect upon the signals that the THERMAL SENSOR sends to the Receiver. TECHNICAL NOTE: The THERMAL SENSOR records the temperature at the HOT water pipe and sends a temperature reading to the Receiver. The Receiver processes the temperature data sending a signal to the Transmitter to activate the water heater to the MODE setting, on the TRANSMITTER. 15. ATTACH THE THERMAL SENSOR HEAD TO THE HOT WATER PIPE VERY IMPORTANT INSTRUCTIONS THE PROPER POSITIONING OF THE THERMAL SENSOR HEAD IS ONE OF MOST IMPORTANT STEPS IN THE INSTALLATION OF THE AQUA SMART™ SYSTEM. THIS COMPONENT CONTROLS THE REMOTE TEMPERATURE OPERATIONS OF THE SYSTEM
A BY-PASS switch has been included on the Receiver allowing the user to by-pass the Receiver powering the water heater directly. When the BY-PASS switch is activated, from the AUTO position to the BY-PASS position, the water heater will operate normally, however the water temperatures will be maintained at the temperature settings of the “on-board” thermostats that are on the water heater. The AQUA SMART™ system will be by-passed and the water heater will cease to operate, wirelessly. BY-PASS AUTO Should the AQUA SMART™ system stop working or become inoperative, review the TROUBLESHOOTING GUIDE on page 38 of this manual or contact the dealer from who the system was purchased or visit our website at: www.aquaenergysaver.com, if the problem is not resolved. 16. SECTION 3 Restore power to the hot water heater at the circuit breaker panel or at the power switch used to disconnect power to the water heater. Upon powering the Receiver, all the LEDs on the Receiver should illuminate and then go off. The Receiver is waiting to “LEARN” the transmitter’s security code. The “LEARN” process is explained on page 24. TECHNICAL NOTE: The Receiver is operated by the 208-240VAC lines powering the hot water heater and therefore it has no batteries. In a rare instance of a power surge or malfunction of the Receiver, the powering of the Receiver may be interrupted and/or damaged. This will be evidenced when the LED lights on the Receiver case are no longer illuminated indicating a problem at the breaker, incoming power lines or with the Receiver. A loss of hot water will also result. Review BY-PASS switch operation in previous section. (See page 16). SECTION 4 1. Locate the TRANSMITTER and hardware bag in carton. The transmitter hardware bag will include: 2 ea. - AAA batteries, 2 ea. - Screw- type Wall Anchors, 2ea. - Mounting screws, 1ea. - Thermometer strip and a paper, mounting template. 2. First, install the 2-AAA batteries into the battery compartment on the back of the Transmitter. When the AAA batteries are installed in the Transmitter all the ICONS on the Transmitter will illuminate for 2 seconds and a single beep will be heard. Several of the LCD icons will illuminate with the HOUR digit blinking. 17. LCD SCREEN RESTORE POWER TO THE HOT WATER HEATER BATTERY COMPARTMENT Do not activate the BY-PASS switch for any other purpose than to override the AQUA SMART™ system should there be a malfunction or TROUBLESHOOTING procedures are being initiated. (See page 38). BY-PASS SWITCH NOTICE: The NORMAL position for the BY-PASS switch is in the AUTO position. This switch should only be activated, to the BY-PASS position, when troubleshooting the water heater or should there be a system failure. When activated, to the BY-PASS position, all power to the Aqua Smart™ Receiver is by-passed and the water heater will be powered DIRECTLY by its electrical source. The water heater will now be controlled by the “on-board” thermostat settings ON THE WATER HEATER. IMPORTANT NOTICE The position of the BY-PASS switch, at the BASE of the RECEIVER, should be in the AUTO position. INSTALL BATTERIES IN TRANSMITTER BY-PASS SWITCH
Each Transmitter for the AQUA SMART™ system has one of 1,048,576 unique security codes embedded into its memory. It will be necessary to program the Receiver to LEARN the security code of the Transmitter, upon initial use, or if a replacement Transmitter has been purchased from your dealer or the factory. 1. Standing approximately 3 feet from the hot water heater, where the Receiver has been mounted, program the Transmitter’s security code into the Receiver. 2. To program the Receiver to LEARN the Transmitter's security code, insert a small screwdriver or punch into the LEARN button hole on top of the Receiver case. Push down gently until a LONG BEEP is heard signaling that the Receiver is ready to learn the Transmitter’s security code. 3. Now press the MODE button on the Transmitter and 5 RAPID BEEPS will be heard confirming that the LEARN process has been completed. When first powered, all 4 of the LEDs, on the Receiver, will remain ON for a short period of time confirming that the LEDs are operational. TESTING THE OPERATING (POWERING) MODES The AQUA SMART™ system features 2– way communication software allowing the RECEIVER and the TRANSMITTER to communicate with each other. This bi-directional communication provides confirmation of the radio frequency (RF) signals being sent between the Transmitter and the Receiver. Each operating MODE initiates different temperatures for the water heater to operate on and are identified by the colored LEDs, on the Receiver, as indicated below. GREEN = ON MODE AMBER = AWAY MODE BLUE = VACATION MODE RED = PROGRAM MODE It is recommended that each of the operating MODES in the AQUA SMART™ system be tested with the Transmitter standing approximately 3 feet from the water heater/Receiver. When any of the MODE buttons are pressed on the Transmitter, the SYNC icon on the Transmitter’s LCD display will display and the command is, wirelessly, sent to the Receiver. When the Receiver receives the command from the Transmitter, a corresponding LED will illuminate on the Receiver and the Receiver will send a wireless, signal back to the Transmitter confirming receipt of the Transmitter's command. 18. TESTING THE OPERATING (POWERING) MODES – (continued) If for some reason the Transmitter does not receive a confirmation signal from the Receiver, within 5 seconds, the WARNING icon, on the Transmitter’s LCD screen, will illuminate on the LCD screen and the mode selection process will need to be repeated. Test all 4 modes in a similar manner. NOTE: Upon the Receiver receiving any of the Transmitter’s signals, you may hear the “clicking sound” of a relay, inside the Receiver case, further confirming receipt of the Transmitter’s command in addition to the illumination of the corresponding LED on the Receiver case. OPERATION OF LEDs: When any of the MODES is in a “powering state” the LED identifying that mode, plus the ON-LED, will illuminate on the Receiver. When the same MODE is not in a “powering state”, it’s LED will illuminate but the ON-LED will not illuminate. NOTE: “Powering state”, means that a MODE is being “powered” and the GREEN LED plus the selected mode’s LED is illuminated. When the MODE is entered and no power is being delivered, only the MODE LED will be illuminated on the Receiver. THE OPERATING TEMPERATURES AND COLOR OF THE LEDs ON THE RECEIVER FOR EACH MODE ARE AS FOLLOWS: · ON: The Transmitter signals the Receiver to manage the temperature of the water heater at the thermostat settings of the “on board” thermostat on the water heater, usually around 120°F. When “powering”, the GREEN LED on the Receiver will be illuminated. · AWAY: The Transmitter signals the Receiver to manage water heater’s operating temperature to between 75°F and 85°F and the AMBER LED on the Receiver will be illuminated. When “powering” the water heater in the AWAY mode, both the AMBER and the GREEN LEDs will be illuminated. · VACATION: The Transmitter signals the Receiver to manage water heater’s operating temperature to between 40°F and 50°F and the BLUE LED on the Receiver will be illuminated. When “powering” the water heater in the VACATION mode, both the BLUE and the GREEN LEDs will be illuminated. · PROGRAM: When in the PROGRAM mode, the Transmitter signals the Receiver, on a daily basis, to manage the water heater from a menu of programmed timed/temperature settings, (ON and OFF), as encrypted in the transmitter by either the “factory program” and/or the program entered into the transmitter by the user. In the PROGRAM mode, the RED led will illuminate. When “powering” the water heater in the PROGRAM mode, both the RED LED and the GREEN LEDs will be illuminated. 19. “LEARNING” PROCESS TEACHING TRANSMITTER’S SECURITY CODE TO THE RECEIVER

Further demonstrations of these functions can be found on our website/video at: www.aquaenergysaver.com. We suggest viewing this video to answer any questions about the AQUA SMART™ system. 21. TRANSMITTER LCD & SET-UP
Follow the SET-UP procedures below, upon FIRST USE of the transmitter. INITIAL SET: Push and hold SET button for more than 5 seconds and then release button for initial set-up. A beeping sound will be heard. The initial settings include settings for TIME, °F/°C conversion, DAY of the Week, BALANCING and WATTAGE of Water Heater. A. SETTING CURRENT TIME: Following the push of the SET button in the step above, the HOUR digits will begin blinking in the TIME window. Press the UP/DOWN buttons to set the current HOUR, in the corresponding AM/PM time period. Press SET button again and the MINUTES will begin blinking. Press the UP/DOWN buttons to set the current MINUTES. Press the SET button again and the °F/°C will begin blinking. C. SETTING THE TEMPERATURE SCALE: Press the UP/DOWN buttons to change the °F/°C scale. (Factory setting is °F). Press the SET button again. The icon S will begin blinking prompting the user to enter the current DAY of the week. 22. D. SETTING THE DAY OF THE WEEK: To change to the current DAY of the week, press the UP/DOWN button to display current DAY. The press the SET button and the BALANCING window will begin blinking. IMPORTANT NOTE: If you are not able to preform the next 2 SET-UP proceedures within the next 30 seconds, the transmitter will return to its NORMAL STATE. When you are ready to restart the SET-UP again, press the SET button for 5 seconds, release button and scroll to CRITICAL ADJUSTMENTS #1 and #2 pressing the SET button several times and prepare to enter the required data. # 1 - BALANCING THE THERMAL SENSOR PREVIOUS INSTRUCTIONS, ON PAGE 6, RECOMMENDED THAT YOU RECORD THE WATER TEMPERATURE FROM THE THERMOMETER STRIP.THIS IS THE READING THAT IS TO BE ENTERED IN THE SENSOR TEMP WINDOW ON THE TRANSMITTER’S LCD. A small THERMOMETER STRIP has been supplied to allow user to measure the ACTUAL temperature of the hot water coming out of a water faucet supplied by the water heater. During the initial set-up process, user MUST adjust the SENSOR TEMP to the actual water temperature coming from a HOT water faucet in the home. From a faucet nearest the hot water heater, fill a glass with hot water and drop the temperature strip into the water. Observe the mid- temperature strip reading on the temperature strip comparing this reading in the SENSOR TEMP window on the Transmitter’s LCD screen. TEMPERATURE STRIP IN GLASS OF HOT WATER TEMPERATURE STRIP Using the UP / DOWN buttons, adjust the SENSOR TEMP temperature reading on the LCD screen to closely match the temperature of the HOT water coming from the water faucet. The “BALANCING” numbers will display in both the SENSOR TEMP and SENSOR TEMP SET windows on the LCD screen during this process. Press the SET button to hold the new BALANCED temperature reading. 23. UP DOWN SET TWO IMPORTANT SETTINGS MUST BE MADE OR THE SYSTEM WILL NOT ACCURATELY CALCULATE THE TEMPERATURE DATA AT THIS TIME, IT IS RECOMMENDED THAT THE USER REVIEW THESE TWO SET – UP PROCEEDURES SO THAT DATA IS READY TO BE ENTERED INTO THE TRANSMITTER, WHEN PROMPTED. #1 – BALANCING THERMAL SENSOR TEMPERATURE #2 – WATER HEATER WATTAGE RATING INITIAL SET – UP & PROGRAMMING OF THE TRANSMITTER
BALANCING FEATURE- (continued) This procedure allows for a more accurate “temperature “triggering” of the AQUA SMART™ system to the Transmitters newly, “BALANCED” temperature. TECHNICAL NOTE: When user activates the BALANCING process and determines that additional BALANCING degrees are needed to be added to the Transmitter’s software, these additional degrees can be added by pressing the UP/DOWN buttons on the Transmitter thereby BALANCING the faucet’s HOT water temperature to the SENSOR TEMP display on the LCD screen. Initially, the factory has embedded 10°F in the Transmitter’s software. User can reduce the 10°F or add up to 25°F to the balancing process depending on the climate and location of the water heater, in single digits. IMPORTANT NOTE: If the “balancing process”, is NOT ACTIVATED, the factory has added a 10°F differential into the transmitter’s software. The purpose of the 10°F differential is to compensate for the average, ambient temperature change between the hot water heater and the THERMAL SENSOR reading on the hot water pipe. Some newer water heaters have a “heat trap” component, installed in the HOT water outlet pipe preventing heated water from being drawn into the home’s piping system when there is no demand for HOT water. This can reduce the pipe temperature at the location of the THERMAL SENSOR. The 10°F will remain in the software whether or not the user activates the “balancing process”. After the balancing process has been completed, the new SENSOR number will display in the SENSOR TEMP window, only. Continuing to the last Initial Set-Up procedure, press the SET button to continue programming the WATTAGE of the water heater that the Receiver has been installed on. # 2 WATER HEATER WATTAGE RATING WATER HEATER WATTAGE RATING: The water heater WATTAGE rating must be entered into the transmitter during the INITIAL SET- UP procedure. User MUST match the WATTAGE rating of the water heater to the Receiver that the AQUA SMART™ has been installed on. This procedure is necessary to allow the system’s software to accurately calculate the kWh electrical usage when the water heater is operating. On the front of the water heater jacket, there will be several labels. Locate the label that lists the water heater capacity and electrical specifications. A standard label will then list PHASE, VOLTAGE-AC, UPPER ELEMENT, LOWER ELEMENT and TOTAL CONNECTED WATTS. (Continued) 24. WATER HEATER WATTAGE RATING- (continued) These headings may be followed by two columns of ratings listed as PHASE 1. The first column may be headed 208 and the second may be headed 240.The column headed 208 will list wattage ratings for 208 voltage systems, usually found in CANADA. The column headed 240 will list wattage ratings for 240 voltage systems, found in the U.S. User MUST locate the water heater wattage rating from the label on the front of the water heater or Owner’s manual and enter that data during the SET–UP procedure. During the initial set up, user MUST set the WATTAGE rating. in the transmitter to match the water heater WATTAGE rating that the Receiver has been installed on. The factory-set number 3000W. Press the UP/DOWN buttons to make the change. The WATTAGE rating numbers appear in the kWh Use/Mo. window on the LCD screen. Changes to the WATTAGE rating can be viewed in this window and are listed in 100 watt increments. Scroll through the water heater WATTAGE ratings on the LCD screen and when user’s water heater rating is displayed, in the kWh Use/Mo. window, press the SET button matching the two WATTAGE rating numbers. This completes the transmitter set-up and the icons should stop blinking and the LCD should appear as pictured below. The AQUA SMART™ system is designed to operate on electric hot water heaters rated from 3000W to 6000W. 25. THE INITIAL SET-UP OF THE TRANSMITTER HAS BEEN COMPLETED AND THE NORMAL STATE OF THE LCD SHOULD APPEAR AS BELOW
THE FOLLOWING SECTIONS REGARDING PROGRAM OPERATION ARE ONLY APPLICIABLE WHEN USER SCROLLS TO THE PROGRAM MODE. The AQUA SMART™ can operate from a factory-installed program or one entered by the user. A description of both these programs follows with reprogramming instructions. FACTORY-SET PROGRAM – The transmitter has a factory-set program that has been encrypted into the software with factory-set, ON-OFF settings to operate the water heater. This factory-set program will operate ONLY when in the PROGRAM mode, and will be overridden when a user enters his personal program. The factory –set program is displayed below: FAC FACTORY-SET PROGRAM MODE ON (TEMP. SETTING) OFF (TEMP. SETTING) MORN: 5:00 am (120°F) 8:00 am (75°F) DAY: 4:00 pm (120°F) 6:00 pm (75°F) NITE: 7:00 pm (120°F) 9:00 pm (75°F) The temperature for the ON setting is 120°F. However, if the “on board” thermostat settings on the users’ hot water heater are higher than 120°F, the software commands the system to “default” to the “on board” thermostat setting on the water heater. For safety purposes, this setting should be at 120°F. However, it could be higher if the user has set the “on board” thermostats to a higher temperature, but only 120°F will show on the LCD. The temperature for the OFF setting is 75°F. When the water temperature drops to 75°F, the water heater is “powered” and shuts off at 80°F. Review the matrix/protocol for the ON - OFF temperature settings and the “triggering spreads” between ON - OFF at the end of this manual. (See pages 36-37). IMPORTANT NOTE: The FACTORY –SET program settings may not match with the user’s daily activities and reprogramming, by the user, may be necessary. User programming instructions are covered on pages 27-29. 26. PROGRAM OPERATION OF THE AQUA SMART™ SYSTEM – (continued) USER-SET PROGRAMMING PROCEEDURES- User may change the following settings, but only in the PROGRAM mode. Below is a list of “user” program settings. · PERIODS OF THE DAY: MORN DAY NITE (For each DAY OF THE WEEK: S - M - T - W - T - F - S) · HOUR OF DAY WITHIN EACH PERIOD · ON - OFF TEMPERATURE SETTINGS WITHIN EACH PERIOD User can program the daily operation of the AQUA SMART™ system following the programming procedures below. 1.

At the end of the user programming process, press the SET button to “lock in” the new “user program”. 28. IMPORTANT NOTE: User settings are limited to between 75°F and 120°F. The lowest temperature for the OFF setting is 75°F. When the water temperature drops to 75°F, the water heater is “powered” and shuts off at 80°F. The highest OFF temperature setting is 120°F. MATRIX - PROTOCAL TEMPERATURE RESTRICTIONS When user SETS a temperature to ON, user can also set the OFF temperature, however, the setting for the OFF temperature can be no less than 10°F from the ON temperature setting. Review the matrix - protocol charts for the ON - OFF temperature settings and “triggering spreads” between ON - OFF on pages 36-37. Temperature settings between the 75°F and 120°F will operate within a 5°F temperature spread/swing. (See page 37).Should user want to set lower temperatures, user can activate the VACATION mode but will have to remember to return to another mode for higher temperatures. 7. PROGRAM REVIEW: To review program settings, enter a short push of the PROGRAM button which enables user to review either the factory-set or user-set PROGRAM settings. Then, continue to enter short pushes on the PROGRAM button to review all the programmed settings. Press SET button when review completed. CHANGING/CANCELLING PROGRAMS: User may change the factory-set program by following the procedures as outlined in steps 1-6. Should user wish to return to the factory-set program, PUSH and HOLD the UP and PROGRAM buttons, at the same time for more than 5 seconds, and user-set program is cancelled and the system reverts back to the factory-set program. The transmitter will emit 4 short beeps confirming the cancellation step. 8. OVERRIDE: The OVERRIDE feature only operates in the PROGRAM mode. User may change the current SET TEMPERATURE in the PROGRAM mode without changing the other programs stored in the transmitter. When in the PROGRAM mode, user can push UP/DOWN buttons to change factory-set and/or user-set TEMPERATURE settings, in single digits. The word OVERRIDE will appear on the LCD and the OVERRIDE feature activates. The OVERRIDE setting will be automatically cancelled at the start of the next PROGRAM PERIOD. 29.
SECTION 5 Once the AQUA SMART™ is properly installed and the Transmitter has been “set-up” and “programmed”, the system is ready to begin reducing energy costs. It is imperative that the USER becomes PROACTIVE in setting one of the MODES when there is a planned absence from the home. If the PROGRAM MODE is engaged, the savings may be even greater as the system will be automatic, on a daily basis. To help with the energy saving process, when the user has forgotten to engage the AQUA SMART™ system, the system has a Built-In feature referred to as the AQUA SMART MODE. AQUA SMART MODE: The AQUA SMART™ system includes another ENERGY SAVINGS feature that “automatically” produces energy savings when the user forgets to set a MODE prior to leaving the residence for more than two days. A brief explanation follows: · The AQUA SMART™ system monitors changes in the hot water temperature using the THERMAL SENSOR that is attached to the hot water pipe on the hot water heater. During every 3 hour period, the SENSOR records temperature changes, storing the information in the system’s software. If, during this 3 hour period, there is a change in the water temperature, these records are erased and the system begins a new 3 hour monitoring period. · If there are no temperature changes, greater than 10° F during a 2 day period, the system AUTOMATICALLY defaults to the AWAY mode setting. In the AWAY mode, the temperature is maintained between 75° F and 85°F. The water heater reduces energy consumption while in the AWAY mode. · When the AQUA SMART MODE is engaged, the AWAY icon on the Transmitter, will cycle ON and OFF for 1 second, alternately. Additionally, the Transmitter will emit 8 short, beeping sounds, at the transmitter, every 15 minutes alerting the returning homeowner that the system has entered the AWAY setting in the AQUA SMART MODE and the user needs to reset the Transmitter. The AMBER LED on the Receiver will also be blinking. 30. OPERATING FEATURES OF THE AQUA SMART™ SYSTEM - (continued) KILOWATT (kWh) HOUR USAGE The AQUA SMART™ system features an ENERGY USAGE factor which uses its software to calculate the amount of time the water heater is operating sending that data to the Transmitter. This data will be displayed in kWh Use/Mo window on the LCD screen. Each 30 days, the Transmitter resets the kilowatt usage data to zero (0) allowing the user to review energy usage for each 30 day period. User can override kWh Use/MO. setting and reset to “0” at any time to restart calculation. NOTE: This feature will only be accurate if the user has entered the water heater’s WATTAGE RATING. (See pages 24-25 for proper setting). To reset this reading, push and hold the SET and DOWN buttons, at the same time, for more than 5 seconds. This feature also stores up to 12 previous records of kilowatt usage. To review previous records, push and hold the SET and PROGRAM buttons for more than 5 seconds and those records will appear in the kWh Use/Mo. window. At the same time, the number of stored records will appear in the TIME window on the LCD. To return to the normal state, press SET button. This feature allows the user to monitor the energy use of the hot water heater and adjust the system to maximize energy savings by being PROACTIVE in engaging the energy saving features of the AQUA SMART™ system. HEATING ICON: When the AQUA SMART™ system is in the ON or “powering state”, in any of the MODES, the HEATING icon (with steam trails) will begin blinking and continue blinking until the power to the water heater switched OFF. 31. OPERATING FEATURES OF THE AQUA SMART™ SYSTEM
OPERATING FEATURES OF THE AQUA SMART™ SYSTEM - (continued) TWO-WAY COMMUNICATION: A “two-way” SYNC icon will be displayed on the LCD screen indicating that the radio frequency (RF) signals, between Transmitter and the Receiver, are communicating with each other confirming commands sent by the Transmitter and/or the Receiver. This icon will be illuminated at all times. Should the 2 way communication between the Transmitter and/or the Receiver be interrupted or stop working, a series of 4 rapid beeps will be emitted from the Transmitter, every 15 minutes, to alert the user of a problem that needs to be corrected. WARNING TRIANGLE: A “warning” icon is displayed, on the LCD, when the Transmitter is out of the RF operating range of the Receiver, as well as indicating other problems with the AQUA SMART™ system. A beeping signal, consisting of 4 rapid beeps every 15 minutes emits from the Transmitter, indicating there is a problem which the user must resolve. (See page 38). LOW BATTERY: A “low battery” icon alerts homeowner when it is time to replace batteries with a “blinking” icon. When battery is low, the Transmitter will emit 3 long beeps every hour to remind user to change batteries. It is suggested that batteries be replaced every 12 months. The Transmitter operates on 2-AAA batteries. When the batteries are removed, the software in the Transmitter will memorialize all settings with the exception of TIME, DAY of WEEK, TEMPERATURE SENSOR and KWh Use. 32. LOCKOUT: A “lockout” feature allows the user to set a LOCKOUT mode on the Transmitter, only to be unlocked by the user that programmed the Transmitter. Press and hold the SET and UP buttons for more than 5 seconds to activate or deactivate this feature. MOUNTING THE TRANSMITTER After testing and observing the MODE operations of the Transmitter in the proximity of the water heater/Receiver, take the Transmitter to the area in the home that you plan to install it. NOTE: It is advised that you test all MODES, on the Transmitter, from the remote location that you plan to install the Transmitter. Depending on the distance from the water heater and from any electrical interference in the home, you want to be sure the wireless Transmitter operates from this remote location. It is recommended that the Transmitter be mounted on a wall near the home's heating/cooling thermostat. Positioning near the home thermostat prompts the user to “set back” both the water heater and the heating/cooling thermostat, at the same time, thereby conserving energy throughout the home. With the PAPER TEMPLATE provided with the Transmitter hardware package, mark two mounting holes on the wall with a pencil. SUGGESTION: Use a level to align properly. Follow the mounting instructions written on the TEMPLATE, below. 33.
The previous sections in this manual have been instructive from the standpoint of providing the user a thorough understanding all the various features that have been included in the AQUA SMART™ system. The key element in saving electrical energy, using the AQUA SMART™ system, is WITH THE USER. With a conscious effort by the user to engage and monitor the AQUA SMART™ system, hundreds of dollars can be saved each year and over the lifetime of the installation. The LCD displays the 4 operating MODES that are the operating protocol for the AQUA SMART ™ system and are activated by the MODE button on the Transmitter. The TRANSMITTER operates in one of 4 modes: ON–AWAY – VACATION- PROGRAM ON MODE: In the ON mode, the water heater will operate at 120°F or at whatever thermostat setting on at the water heater’s thermostats. Manufacturers’ factory settings are usually at 120°F but can be adjusted by the homeowner. The ON setting is the least economical setting for the system but is necessary when the residence is occupied. The normal operating temperature of the AQUA SMART™ system, when NOT in the AWAY, VACATION or PROGRAM modes, will be whatever the “on board” thermostat settings are on the water heater. (See water heater’s operating manual to make any temperature adjustments). Review the CPSC Government chart regarding the Danger Zones for hot water heating in an earlier section in this manual. (See page 37). 34. SELECTING THE OPERATING MODE FOR THE MOST EFFICIENT OPERATION OF THE AQUA SMART SYSTEM – (Continued) AWAY MODE: In the AWAY MODE, the water heater will operate between 75°F and 85° F reducing the energy consumption when the homeowner is away for 2 days or up to 7 days. As an electric water heater can consume from between 17% to 29% of a residential electric bill, reducing the amount of energy to maintain higher temperatures is recommended. VACATION MODE: In the VACATION MODE, the water heater will operate between 40°F and 50°F thereby reducing energy consumption. This setting is recommended when the homeowner will be away for 7 days or longer periods of time. This is the most economical mode to engage for the greatest energy savings. When the AQUA SMART™ system is in this mode, there continues to be power to the water heater and it safely maintains the water temperature in the water heater, above the freezing point of (32°F/0°C), when the water heater installation is in a garage or in a vacation home. NOTE: Depending on the make and age of the water heater that the AQUA SMART™ system has been installed on, the water temperature recovery from the VACATION mode to the normal water temperature can range between 1 and up to 2 hours. PROGRAM MODE: When engaged in the PROGRAM mode, the water heater operates at the “factory-set program” or the “user-set” program entered by the user during the PROGRAMMING process. The Transmitter has a “default”, FACTORY-SET program encrypted into the software which will operate system only in PROGRAM mode. Should user decide to revert to the FACTORY-SET program, after completing the USER-SET programming process, user can push and hold the UP and the PROGRAM buttons, at the same time, for 5 or more seconds and cancel the USER-SET program and revert back the FACTORY-SET program. This will cancel the user-set program that had been previously entered. User will have to enter a new program should the old program be deleted. UNDERSTANDING THE ADVANTAGES OF SETTING THE MODES OF OPERATION OF THE AQUA SMART™ WATER HEATER, WIRELESS SYSTEM WILL SAVE ENERGY COSTS THROUGHOUT THE LIFE OF THE WATER HEATER. 35.

TROUBLESHOOTING GUIDE There are numerous possibilities that could cause a malfunction of the water heater and/or the AQUA SMART™ system. To properly diagnose any problems, first troubleshoot the WATER HEATER and then the AQUA SMART™ system. To do this, refer to page 16 of this manual for an understanding of the BY-PASS switch. NOTE: Be sure to check the batteries in the transmitter to be sure they are at full power. 1. First, be sure that the power source has not been interrupted by checking the panel box making sure the breaker has not tripped or a fuse has blown. 2. If that was not the problem, then move the BY-PASS switch, on the Receiver, from AUTO to BY-PASS position allowing the water heater to be powered directly from the power source. 3. Then check the operation of the WATER HEATER performing all the Troubleshooting Tests recommended in the, Owner’s Manual that came with the water heater. This will entail checking the incoming power/voltage with a circuit tester or volt meter, determining that the RED, hi-limit switch/Reset button has not been tripped, and checking for defective thermostats or heating elements. 4. Check that the thermostat setting is at the recommended 120 °F. If all of the above tests prove positive, then switch the BY-PASS switch back to AUTO and start testing the AQUA SMART™ Receiver. 1. First check the batteries in the transmitter to be sure they are at full power. 2. Remove the transmitter from the wall where it has been installed and begin testing within 3 feet from the water heater/Receiver. (See pages 18-19). 3. Be sure that the LEDs are working by changing the MODES on the transmitter. If the LEDs illuminate on the Receiver and you hear a clicking sound, then the transmitter and AQUA SMART™ Receiver are communicating. As with other electrical devices, sometimes removing the power source from the device will reset the software and the problem may resolve itself with this simple operation. Try re-setting the circuit breaker at the power source. 4. If the relay does not respond and the LEDs are not changing, then there may be an internal problem with the Receiver which will require the removal of the Receiver cover to check the circuits. If you are not familiar with testing electrical components, we STRONGLY recommend that you contact a qualified electrician to conduct a further diagnosis of the Receiver.
