24 Vac Common Power (Recommended)  
recommended that the comfort control be solely powered  
with the three AAA batteries during normal system  
operation. When using batteries, make sure positive and  
negative terminals are oriented correctly, as marked on  
the device. See Fig. 16.  
Wire the common side of the transformer to the B screw  
of the comfort control wallplate. When installing in a single  
transformer system, keep the jumper wire between the R  
and Rc screws. When installing in a two-transformer  
system, use the common from the cooling transformer to  
connect to the B screw and remove the jumper wire  
between the R and Rc screws.  
Battery Power (Optional)  
CAUTION  
Equipment or Property Damage Hazard.  
Using battery power only may not provide  
adequate power to comfort control and can  
cause damage during freezing conditions.  
Connect the 24 Vac Common (B) wire from the  
system transformer to the comfort control for  
proper operation when the battery power is  
drained.

does not energize when the comfort control calls for heat.  
OPERATION IN THE EMERGENCY HEAT MODE  
Once the comfort control is placed into the Emergency  
Heat mode, the compressor and auxiliary lockout features  
are turned off. In the Emergency heat mode, the  
compressor is locked out. The first stage of heat is  
whatever is connected to the X2 terminal. The second  
stage of heat is connected to the W1 terminal. Usually the  
emergency and auxiliary heat sources are electric strip  
heat in these cases.  
OPERATION IN EMERGENCY HEAT MODE  
The balance point (outside) temperature is not used in the  
Emergency heat mode. When the comfort control is  
moved to the Emergency Heat position, the compressor is  
locked out. The first stage of heat is whatever is  
connected to the X2 terminal. The second stage of heat is  
what is connected to the W1 terminal. Often there is only  
one source of non-compressor heat and the X2 terminal is  
jumpered to the W1 terminal.  
Dehumidification Droop Control
