TYPICAL WIRING DIAGRAMS

Notes:

1. For HVAC systems with a single transformer for heating and cooling, leave the metal jumper

between Terminal 1 (RC) and Terminal 2 (RH) on the left terminal strip must in place. See Figure 3.

2. The EER56100 thermostat is factory-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, configure the

“System Type” settings under “System Options.” See “Setup and Configuration” on page 16.

— 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), configure the “Cool Stages” and “Heat Stages”

settings under “Stage Settings.” See “Setup and Configuration” on page 16.

3. When configured as a conventional thermostat, by default this thermostat does not turn the fan on

with a call for heat. If the furnace requires the thermostat to turn the fan on with a call for heat,

configure the “System Mode” to “Fan On With Heat” under “System Options.”

4. A conventional thermostat can be configured for automatic changeover heat/cool, manual

changeover heat/cool, heat only, or cool only thermostat. Refer to the “Configuration” steps

associated with the wiring diagram for the HVAC system type.

5. If the thermostat or HVAC system does not perform as stated in the “Power Up” steps under the

wiring diagram for the HVAC system type, recheck all wiring. See “Troubleshooting” on page 23.

6. For HVAC systems with separate heating and cooling transformers, remove the metal jumper

between Terminal 1 (RC) and Terminal 2 (RH) on the left terminal strip. See Figure 4 on page 5.
