4 Physical Installation and Wiring Cautions!  We highly recommend that this installation procedure is performed by a trained HVAC technician.  Read the enclosed instructions carefully before installing your new ZTS-500US. Pay close attention to all warnings and notes and carefully follow the installation steps in the order they are presented to save time and minimize the risk of damaging the thermostat or the system it controls.  Before disconnecting wires from the existing thermostat, label the wires with the terminal markings from the old thermostat and record them. Take a picture of the old wiring as it will be very helpful with troubleshooting in case you need to reinstall the old unit.  Turn off electronic devices (e.g. heater, cooler) which will be connected and the electric source before installation and maintenance.  Do not use metal conduits or cables provided with a metal sheath.  Adding fuses or protective device in the line circuit is recommended. Battery safety!  Use new batteries of the recommended type and size only.  Never mix used and new batteries together.  To avoid chemical leaks, remove batteries from the ZTS-500US if you do not intend to use the unit for an extended period of time.  Dispose of used batteries properly; do not burn or bury them. Read following scenarios carefully before you start as it matters to the battery life under Z-Wave operation: Installation Location This thermostat is restricted to indoor use only. It should be mounted on an inner wall about 5ft (1.5m) above the floor at a position where it is readily affected by changes of the general room temperature with freely circulating air. Avoid mounting above or near hot surfaces or equipment (e.g. TV, heater, refrigerator). Avoid mounting where it will be exposed to direct sunshine, drafts, or in a laundry room or other enclosed space. Do not expose this unit to dripping or splashing liquids. Physically Installing the Thermostat 1. Open the ZTS-500US by pulling the two sections apart (Figure 2). Use the fingertips of one hand to grip the tab on the front housing. 2. Insert the two included wall anchors into the wall, aligned with two of the mounting holes in the back housing of the thermostat. 3. Open the terminal block of the ZTS-500US then insert all necessary wires through the back housing (Figure 3). 4. Fasten the back housing to the wall using the two included mounting screws. Insert the screws through the mounting holes in the housing and into the wall anchors (Figure 3). 5. Wire the proper cables to the terminal block according to the circuit diagram as described in figure 4 and "Thermostat Terminal Wiring". Afterward, push all cables back into the wall then close the terminal block of the ZTS-500US. 6. The ZTS-500US can be powered by either two AA Alkaline batteries or four AA Alkaline batteries. Match the polarity of the batteries with the +/- marks inside the battery compartment. 7. Align the front housing of the thermostat with the back housing and push until the housing

16 Explanations of Set point, Swing, Differential and Dead band HEAT mode: Thermostat controls the temperature according to the following diagram Example: If Heat Set point = 70°F, Swing = 1°F, Differential = 2°F, then => 1st stage heater turns on when room temp is 69°F and off at 71°F. => 2nd stage heater turns on when room temp is 67°F and off at 70°F. COOL mode: Thermostat controls the temperature according to the following diagram Example: If Cool Set point = 80°F, Swing = 1°F, Differential = 2°F, then => 1st stage cooler turns on when room temp is 81°F and off at 79°F. => 2nd stage cooler turns on when room temp is 83°F and off at 80°F. AUTO mode: Thermostat controls the temperature according to the following diagram. Press + / - buttons to adjust the appropriate set point. It will adjust the set point that is closer to the current room temperature.  If the current temperature is close to heat set point, then it will change the heat set point value.  If the current temperature is close to cool set point, then it will change the cool set point value.  If the difference between the two is equal, then it will change the heat set point value by default.  There is a dead band 4°F/2°C (by default) between heat set point and cool set point. If user select heat set point is 73°F, then the minimum of cool set point will be limited to 77°F. Output Set point Temperature Swing 1st stage Turn off 1st stage Turn on Off Heat 2nd stage Turn on 2nd stage Turn off = Set point Diff Swing Output Set point Temperature Swing 1st stage Turn on Off Cool Diff Swing 2nd stage Turn on 2nd stage Turn off = Set point1st stage Turn off 67oF 68oF 69oF 70oF 71oF 72oF 73oF 74oF 77oF 78oF 79oF 80oF 81oF 82oF 83oF 84oF

22 Glossary Device or Node Devices and nodes are all terms to describe an individual Z-Wave device. These are all interchangeable when setting up your Z-Wave network. Inclusion Add a Z-Wave device to the network. Exclusion Remove a Z-Wave device from the network. Remove To take a device out of a group, scene, or association group while that device still exists in the same Z-Wave network. Network Wide Inclusion (NWI) Network Wide Inclusion (NWI) enables both end-user friendly, Plug and Play like Z-Wave network installation as well as professional installation scenario where the inclusion process, in terms of time, will be reduced significantly. NWI is a feature supported by a new frame type named Explorer which enables the Z-Wave protocol to implement Adaptive Source Routing. Z-Wave Network A collection of Z-Wave devices is controlled by primary and secondary controllers operating on the same system. A Z-Wave network has its own unique ID code so that controllers not in the network cannot control the system. Primary Controller The first controller is used to set up your devices and network. Only the Primary Controller can be used to include or remove devices from a network. It is recommended that you mark the primary controller for each network for ease in modifying your network. FLiRS Mode FLiRS is abbreviation for “Frequently Listening Routing Slave”. FLiRS mode is targeted for battery operated applications and will enter sleep mode frequently in order to conserve battery consumption. The response to Z-Wave command is not as quick as Always Listening Device. Normally there is 1-2 seconds latency. Always Listening Mode Always Listening mode is targeted for AC power operated applications and it can act as a repeater, which will re-transmit the RF signal to ensure that the signal is received by its intended destination by routing the signal around obstacle and radio dead spots. The response to Z-Wave command is immediate. Association Association is used to organize nodes in different groups allowing the device to identify the nodes by a group identifier. The groups can also be copied to other devices.
23 Z-Wave Setup and Operations You may check Glossary for the definition of FLiRS mode and Always Listening Mode before select the Z-Wave operation mode. Select FLiRS or Always Listening Mode ZTS-500US can be powered by 4 x AA batteries, and/or 24Vac C wire. Before inclusion procedure, user needs to check the operation mode or the power source of ZTS-500US. - FLiRS mode (Batt) is targeted for battery operated applications and will enter sleep mode frequently in order to save battery life. ZTS-500US can’t act as a repeater in this mode. The response to Z-Wave commands is not as quick as devices on Always Listening mode. Normally there is 1-2 seconds latency on response, you should avoid sending commands to the ZTS-500US too frequently. If it is powered by batteries, ZTS-500US will self-configure to FLiRS mode after inclusion into a network. - Always Listening mode (24V) is targeted for AC power operated applications and it can act as a repeater which will re-transmit the RF signal to ensure that the signal is received by its intended destination by routing the signal around obstacle and radio dead spots. The response to Z-Wave command is immediate. If it is powered by 24Vac or 24Vac plus batteries, ZTS-500US will self-configure to Always Listening Mode. Important: a) Regardless of FLiRS mode or Always Listening mode, the setup and operations are the same. Local control can also be used while it is included into a Z-Wave network. b) After inclusion procedure, changing between FLiRS and Always Listening mode is not allowed. To switch modes, you must perform an exclusion procedure first. c) If you are using battery power as the main power source or as a back-up while AC power is down and the ZTS-500US is in Z-Wave Always Listening mode, the battery will drain very fast (battery will only survive 3-5 days). d) If the user performs a Reset to Factory Default Settings or Z-Wave Exclusion operation, the ZTS-500US will retain the last selected HVAC system type.

32 Frequently Asked Questions Q Why won’t my ZTS-500US work with the Z-Wave devices purchased in another country? A Due to differing regulations in different countries, Z-Wave products from different regions are set to different frequencies. Before purchasing new devices, be sure to check if the devices are compatible in your region. Q Do I need an electrician to install a ZTS-500US in my home? A It is strongly recommended that a qualified technician install this product. Q How do I know which product is compatible with my ZTS-500US? A The ZTS-500US is compatible with any Z-Wave controller or gateway that has the control capability for “Thermostat” devices. All Z-Wave products are also labelled with the Z-Wave logos shown below. Q Can I use 2 or more ZTS-500US in my house? If so, what is the max. units? A Yes, you can use multiple ZTS-500USs in a single home. The maximum number of units depends on the capabilities of the gateways and controllers. For example, different gateways can support up to 8, 16, or 32 ZTS-500US on a given network. Q What is the recommended battery type for the ZTS-500US and what is estimated batteries service life? A Alkaline batteries are recommended for the ZTS-500US. Batteries service life is very dependent on the amount of usage per day. With normal use, approximate battery service life is 1 year while operated in FLiRS mode. If you are using battery power as the main power source or as a back-up while AC power is down and the ZTS-500US is in Z-Wave Always Listening mode, the battery will drain very fast (battery will only survive 3-5 days).

Performance can vary depending on the amount of objects in between Z-Wave devices such as walls and furniture. Every Z-Wave device set up in your network will act as a signal repeater allowing devices to talk to each other and find alternate routes in the case of a reception dead spot. Radio frequency limitations: 1. Each wall or object (i.e.: refrigerator, bookshelf, large TV, etc) can reduce the maximum range of 65 feet (20m) by up to 20 to 30%. 2. Plasterboard and wooden walls block less of the radio signal then concrete, brick or tile walls which will have more of an effect on signal strength. 3. Wall mounted Z-Wave devices will also suffer a loss of range if they are housed in metal junction boxes which could also reduce the range by up to 20 to 30%. Maintenance Do not expose your unit to dust, strong sunlight, humidity, high temperatures or mechanical shocks. 1. Do not use old and new batteries together as old batteries tend to leak. 2. Do not use corrosive or abrasive cleansers on your unit. 3. Keep the unit dust free by wiping it with a soft, dry cloth. 4. Do not disassemble the unit, it contains no user-serviceable parts.
