INTRODUCTION A92269 Fig. 4---Chain Spring Installation The Heat Recovery Ventilator (HRV) is used to exchange indoor stale air with outside fresh air. The HRV unit is equipped with a special heat recovery core which transfers sensible heat between the fresh incoming air and stale exhaust air. Step It is recommended, but not required to locate the HRV in a conditioned space. Special attention should be given to condensate drain, duct application, balancing HRV, and locating unit for easy access and routine maintenance. 2_lndependent System In the absence layout, the HRV can be applied of a forced-Mr unit. To ensure both fresh-air, throughout comfort, Application system and a typical as an independent this type of application and remm-air duct system or stand alone involves running registers (or stale-Mr pickup registers) the home. The cross-flow design core allows entering and leaving Mr streams to transfer heat energy without mixing. (See Fig. 15, and 18 through 25.)

WALL CONTROL Step 4_Automatic Step 1---Location The HRV wall controls are unique to HRV and must be installed for proper unit operation. Three wall control options are available: NOTE: This control is designed to be used primarily with installations which are independent of a forced air system (models HRVCCSVU and HRVCCLVU only). I. Basic Control 2. Standard Control 1. Initially the switch is off. All LEDs are off and HRV is inoperative. 3. Automatic Control Step 2IBasic Control Operation 2. First push of mode button puts HRV into intermittent mode. The HRV operates at high speed when there is a call for dehumidification. Intermittent and exchange LEDs are illuminated. When dehumidistat is satisfied, HRV shuts down and exchange LED goes out. The b_sic control contains a 3 position slide switch which is used to manually select OFF, LOW. and HIGH speed blower operation. The unit operates continuously when LOW or HIGH is selected. tSee Table 1.) Step 3iStandard Control Operation 3. Next push of mode button puts system in continuous mode. Continuous and exchange LEDs remain on. The HRV operates at high-speed blower during calls for dehumidification and low speed when dehumidistat is satisfied. The standard control contains an adjustable dehumidistat, and a 3 position slide switch which is used to manually select between OFF. LOW, and INTERMFIq_NT modes. There are 2 LEDs on the control to indicate operating mode. (See Table 2.) This control offers 2 modes of operation: I. With switch off, HRV is inoperative (See Fig. 14.) Control Operation This control contains an adjustable dehumidistat and push button switch to cycle between 3 modes of operation. There are 5 LEDs to indicate mode of operation. (See Table 3.) 4. Next push of mode button puts system in circulation mode. HRV operates in high speed at all times. Circulation LED remains on. When there is a call for dehumidification, exchange LED is on and HRV exchanges air with outside. When dehumidistat is satisfied, HRV dampers close which recirculates indoor air. The exchange LED goes off. and both LEDs are out. 2. With switch on LOW, HRV continuously exchanges air with outside. If dehumidistat is satisfied, blower will run in low speed, otherwise, blower will run on high speed. Both LEDs are illuminated all the time. 5. The maintenance light illuminates every 3 months to indicate filter should be cleaned. It is reset by opening the door to the HRV. 3. With switch on INTERMIq'I'ENT, the HRV exchanges air with outside on high-speed blower, and unit shuts down when dehumidistat is satisfied. The ON LED is illuminated all the time, and AIR EXCHANGE LED is illuminated only when unit is running. This mode is ideal for maintaining proper humidity, levels when no one is home. NOTE: The standard and automatic controls sense humidity not temperature. Either control must be located in an area where it will continually monitor fresh air circulating within the home. Install HRV wall control as close as possible to main system thermostat and follow same guidelines as installing a thermostat, (locate approximately 5 ft.

CONNECTIONS BLACK _..,,=__..__ ELLOW Wiring The HRV operates on 115vat, It comes with a power cord attached to unit and ready to plug into a fused outlet. Unit must be grounded for proper operation. A98383 Fig. 11--Typical Wall Control WALL CONTROL Iooo ] o CONTROL o A98410 Fig. 12---Control Step 2--20 Minute Timer All electrical connections must comply with National and Local Electrical Codes, or other ordinances that might apply. A push button timer can be used to override the wall control and put the HRV into high speed for 20 minutes. Connect switches in parallel and connect leads to HRV terminals 1, OC, and OL. (gee Fig. 14.) Push button locations are ideal in special activity areas, such as, bathrooms or kitchen, where high-speed exhaust operation is needed for a short period of time. l'y_[R'_lyi[0]_l Do not use an extension cord as a power source for operating the HRV. Step 2--12-vdc Wiring NOTE: The 20 minute timer will not function properly unless HRV wall control is applied and working correctly. Timing function is internal to electronic circuit board, it is activated by a momentary contact between OC and OL. The 1 connection is to illuminate the push button. The maximum number of push button timers that can be applied is 5. The HRV circuit board, wall control, and accessories operate on 12vdc. See Wall Control section, item Wiring and Fig. l I and 12 for more information. ACCESSORIES Step l_nterlock Connections Relay Step 3--60 The interlock relay kit, Part No. KVAAC0101FIR is required when installing HRV into a forced-air heating and cooling system. (See Fig. 13.) For additional information, refer to Installation Iustructions supplied with interlock relay kit. Minute Adjustable Timer A 60 minute adjustable timer can also be used to override wall control and put HRV into high-speed operation for a select amount of time. Connect timer in parallel with push button timers, or to HRV terminals OC and OL. (See Fig. 14.) The purpose of interlock relay kit is to energize indoor system equipment (furnace or fan coil) blower whenever HRV is calling. If HRV is energized, and indoor system equipment is not, interlock relay will energize and make R and G at indoor equipment. This will insure fresh air distribution throughout the building via the central duct system. The 60 minute timer will provide a minimum of 30 minutes, and a maximum of 80 minutes of ventilation at high speed. When adjustable timer expires, an additional 20 minutes will remain as a result of the internal timer of HRV electronic circuit board. 8 9-PIN THERMOSTAT TERMINALS i HN61KK04' _ ONLY i _ i _ i i; ........

The forced-air furnace (if used for circulation) should be operating in continuous fan mode for normal operating speed. Balancing intake and exhaust airflow is very important for proper system operation and optimum performance when applying an HRV. Unit balancing prevents a positive and/or negative pressure within the home. Balancing the HRV is done by applying temporary flow collars and permanent balancing dampers to the fresh air intake and stale air exhaust ducts. (See Fig. 15 and 16.) Airflow is determined by connecting a magnehelic gage to the temporary flow collar. (See Fig. 17.) Both flow collars and magnehelic gage are included in the accessory start-up balancing kit.

These methods are derived from the Canadian National Building Code 1995 version and the CSA F326.1 revision. DO NOT use HRV during construction of a house or when sanding drywall. This type of dust may damage system. When ventilation requirement is determined, use Product Sheets to reference unit airflow delivery and performance. Airflow During and Defrost The following 2 methods can be used to evaluate the approximate ventilation needs of a house. Accuracy of calculations are dependent upon the information available and knowing critical measuremenU; of the structure. (See Fig. 26.)

See Fig. 27 and 28). When defrost temperature _nsor detects the need for defrost, K5 relay will close for 6 minutes while KI and K2 remain energized. control board and wall control operate on Board Electronic control board must have wall control attached before unit will function properly. Also, configuration jumpers located on control board must match configuration setup shown on Fig. 28 under Jumper Table. In addition, outside air thermistor must be connected to control board for it to operate properly. See Table 6, Temperature -vs- Ohm Chart, for valid temperature range. This closes the outdoor air damper while running HRV blower on high-speed. This process recirculates warm indoor air through heat recovery core which melts any frost that has formed. Water created in this process is collected by HRV and drained away. Frequency of the defrost cycle depends on outdoor temperature (see Table 10). 14 Table 5_Troubleshooting Chart SYMPTOMS CAUSES SOLUTIONS Air too humid Continuous exchange mode used in small houses Use Intermittent Mode Check humidity level settings Defrost condition is in effect Outdoor temperatue is below 23°F Unit will operate when not in defrost mode.

To do this, turn unit to OFF position. Damper should close. DEFROST CHECK 1. Make sure defrost cable is properly connected into J4. 2. Make sure thermistor assembly is correct. Measure thermistor temperature reading with muhimeter. Select multimeter DC measurement scale 0-20v. At connector J4 (without removing thermistor cable), measure voltage between pins of thermistor cable. Depending on temperature of outside air intake, values should correspond with those in Table 9. If reading is not correct (reading llv for short circuit or 5v for open circuit), change thermistor assembly. 3. If thermistor is good, do a RESET and ,see if defrost works. If defrost still does not work, change circuit board. 15 Table 10---Defrost Cycle OUTSIDE TEMPERATURE No Defrost Above 23°F 4°F to -17°F Below -18°F Table 11_U1 JU1B _ JUIC J JUIE JUIF Reverse Damper Operation In = Normal Out = Inverse Factory Set Always In JUID Table 12_umper JUIG Factory Set Always In Locations JUMPER TABLE MODEL JU1A JU1B JU1C JU1D JUIE JU1F JU1G HRVCCLHU1150 OUT IN IN OUT IN IN IN HRVCCLHU1250 OUT IN IN OUT IN IN IN HRVCCSVU1150 IN OUT OUT OUT IN IN IN HRVCCSVU1250 iN OUT OUT OUT IN IN iN HRVCCLVU1150 IN OUT OUT OUT IN iN IN HRVCCLVU1200 IN OUT OUT OUT JN IN IN IN OUT OUT OUT IN IN IN HRVCCLVU1330 ADVANCED Defrost : unit from 2.
