TYPICAL WIRING DIAGRAMS

CAUTION: Be sure to disconnect the power to the control transformer before removing or installing thermostat.

Do not short gas valve, fan, heat relay, or cool relay...even momentarily.

Do not attempt to hook up to live circuits. An accidental connection to a component on the thermostat circuit board could cause damage to the thermostat.

For HVAC systems with a single transformer, the metal jumper between Terminal 1 (RC) and

Terminal 2 (RH) on the left terminal strip must remain in place.

Important Notes:

1.For HVAC systems with a single transformer for heating and cooling, the metal jumper between Terminal 1 (RC) and Terminal 2 (RH) on the left terminal strip must remain in place – See Figure 4.

2.From the factory, the RC-2000 is configured to control a single stage conventional HVAC system.

￿If the HVAC system is a heat pump, dual fuel heat pump, or if the thermostat is connected to a zone control system that requires a sub-base, before operating the thermostat, the “System Type” settings under “System Options” must be configured – See Installation Settings.

￿If the HVAC system is a two stage conventional or two speed heat pump, before operating the thermostat (making a call for heat or cool), the “Cool Stages” and “Heat Stages” settings under “Stage Settings” must be configured – See Installation Settings.
