TYPICAL WIRING DIAGRAMS 

 

CAUTION: 

 

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

 

Do not short compressor relay, fan relay, auxiliary heat relay, or reversing valve...even momentarily.  This will 
blow a non-replaceable fuse. 

 

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.

NOTES 
 
1)

 

As a convenience to the installer, the compressor start up protection delay can be canceled.  To cancel the 
delay, press the Prog key 3 times, then press the Fan key 2 times. 

 
2)

 

"O"  Terminal is energized for cooling 
"B"  Terminal is energized for heating 

 

In most applications, the reversing valve is energized for cooling and should be connected to the "O" 
terminal.  If the heat pump requires the reversing valve to be energized for heating, connect the reversing 
valve to the "B" terminal. 

 
3)

 

"X1" and "X2" are connected to a 24VAC Red LED, most often used to indicate a fault with the heat 
pump compressor. 

 
4)

 

The Emergency Heat Relay (E Terminal) and outdoor thermostats (usually accessories to a heat pump), 
are not used.  The RC-100 automatically controls auxiliary heat efficiently. 

 

The RC-100 requires at least 1 stage of auxiliary heat enabled at all times.  If the heat pump is equipped 
with an outdoor thermostat, it should be removed from the auxiliary heat circuit, or reconfigured so that it 
can only disable 2nd and 3rd stage of auxiliary heat.
