TCONT800AS11AA TOUCH SCREEN PROGRAMMABLE COMFORT CONTROL

Powering the Comfort Control

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 two­transformer 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.

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.
