*Common wire is required in “heat only” or “cool only” applications. Also use a common if heat, cool, or fan relay cannot supply 15mA to power thermostat, without activating.

CONFIGURATION

￿From the factory, the RC-2000 is configured as a single stage conventional heat/cool thermostat.

￿In the default configuration, this thermostat does not turn the fan on with a call for heat. If the furnace does not turn the fan on with a call for heat, the thermostat must be configured to do so under “System Options”.

POWER UP

1.Double check wiring, be sure that there are no stray wires or wire strands at the connections.

2.Connect power to the transformer and system. The display will show the current thermostat settings.

3.Press [FAN] and select “On”. The fan should come on.

4.Press [FAN] and select “Auto”. The fan should go off.

5.Set the Mode to "Heat". Raise the desired heat setting above the current temperature. Ensure that the heating unit comes on. Set the mode to "Off". Ensure that the heating unit goes off.

6.Set the Mode to "Cool". Lower the desired cool setting below the current temperature. Ensure that the cooling unit comes on. Set the mode to "Off". Ensure that the cooling unit goes off.

The RC-2000 thermostat is designed to work with most single state conventional 4-wire HVAC systems (without a transformer common). However, if the RC-2000 “resets” when calling for heat or cool, or if the heat, cool, or fan relay cannot supply 15mA to power thermostat without the relay activating, the transformer common wire or the HAI Thermostat Power Supply Module (Part Number: 30A00-1) is required.
