WALL CONTROLStep 1---LocationThe HRV wall controls are unique to HRV and must be installedfor proper unit operation.Three wall control options are available:I. Basic Control2. Standard Control3. Automatic ControlStep 2IBasic Control OperationThe b_sic control contains a 3 position slide switch which is usedto 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 OperationThe standard control contains an adjustable dehumidistat, and a 3position slide switch which is used to manually select betweenOFF. LOW, and INTERMFIq_NT modes. There are 2 LEDs onthe control to indicate operating mode. (See Table 2.) This controloffers 2 modes of operation:I. With switch off, HRV is inoperative and both LEDs are out.(See Fig. 14.)2. With switch on LOW, HRV continuously exchanges air withoutside. If dehumidistat is satisfied, blower will run in lowspeed, otherwise, blower will run on high speed. Both LEDsare illuminated all the time.3. With switch on INTERMIq'I'ENT, the HRV exchanges airwith outside on high-speed blower, and unit shuts down whendehumidistat is satisfied. The ON LED is illuminated all thetime, and AIR EXCHANGE LED is illuminated only whenunit is running. This mode is ideal for maintaining properhumidity, levels when no one is home.Step 4_Automatic Control OperationThis control contains an adjustable dehumidistat and push buttonswitch to cycle between 3 modes of operation. There are 5 LEDsto indicate mode of operation. (See Table 3.)NOTE: This control is designed to be used primarily withinstallations which are independent of a forced air system (modelsHRVCCSVU and HRVCCLVU only).1. Initially the switch is off. All LEDs are off and HRV isinoperative.2. First push of mode button puts HRV into intermittent mode.The HRV operates at high speed when there is a call fordehumidification. Intermittent and exchange LEDs are illumi-nated. When dehumidistat is satisfied, HRV shuts down andexchange LED goes out.3. Next push of mode button puts system in continuous mode.Continuous and exchange LEDs remain on. The HRV oper-ates at high-speed blower during calls for dehumidificationand low speed when dehumidistat is satisfied.4. Next push of mode button puts system in circulation mode.HRV operates in high speed at all times. Circulation LEDremains 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 whichrecirculates indoor air. The exchange LED goes off.5. The maintenance light illuminates every 3 months to indicatefilter should be cleaned. It is reset by opening the door to theHRV.NOTE: The standard and automatic controls sense humidity nottemperature. Either control must be located in an area where it willcontinually monitor fresh air circulating within the home. InstallHRV wall control as close as possible to main system thermostatand follow same guidelines as installing a thermostat, (locateapproximately 5 ft. [60 in.] above floor, mount on an insidepartitioning wall, ete).6
