In orderto setyour thermostatup asa humidity controller,you will needat leastone(up to four for averaging) temperature/humiditysupportmodule(s)wired to the thermostat.

Locatethe temperature/humiditysupportmodulein the areathat you want to control humidity. Setthe T3tr4 sensor(Humidity) Input to "Control" by moving the # 4 dipswitchto the "on" position. Up to four T3/ T4 humidity sensorscanbe setto control andthe reportedvalueswill be averagedanddisplayed on thethermostat.Important: ~ of the temperature sensorsconnectedto this thermostat can be set to control becausea control temperature input to tbe thermostat will override a control bumidity input.

Heat Pump Applications

If the sensoris beingusedwith a heatpumpthermostatwidI auxiliary heat,the thermostatcanbe configuredto disablethe useof auxiliary heatduring warm weatherandto lock out the compressorwhendIe outdoortemperatureis too cold. This allows for the mostefficient useof energy.

Troubleshooting

Thermostat has no display: Check24 VAC supply. Check for incorrectwiring betweenthe thermostatandsupportmodule. Incorrectwiring candamagethe thermostatandtransformeror blow a fusein the equipment.Make sureall supportmodules havea uniqueaddress.

Thermostat displays very high temperature or humidity: Ensurethat dipswitch6 is setproperly. If dipswitch 6 is setto Tim anda sensorhasnot beenwired to the Tim terminal,no temperatureor humidity readingswill be displayed. Also, if dipswitch6 is setto onboardanda sensorhasbeenwired to the Tim terminal,incorrecttemperaturereadingswill be displayed. Checkwires on remotesensors(flush mountor outdoor/duct)to ensurethatthey arenot touching. If they are, separatethem.

Thermostat displays very low temperature: Remotesensor (flush mountor outdoor/duct)is not connectedto support moduleproperly. Checkwiring.

Thermostat doesn'tdisplay remote temperature/humidity: Make surethatthe supportmoduleis setto address1. Reset supportmoduleafterchangingany dipswitchesby turning off
