TCONT800AS11AA TOUCH SCREEN PROGRAMMABLE COMFORT CONTROL  
Powering the Comfort Control  
WALL  
The comfort control can be powered with 24 Vac.  
24 Vac Common Power (Recommended)  
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.

Adjusting Real-Time Clock  
Setting Calendar and Time  
Locate and remove the tab labeled Remove in the lower  
left corner on the comfort control back. The tab must be  
removed to activate the real-time clock. See Fig. 10.  
Three AAA alkaline batteries can be used to power the  
comfort control for armchair programming only. To  
prevent the comfort control and heating/cooling system  
from shutting down due to lack of battery power, it is not  
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. 8.
