AC Power
The Comfort Control must be  
powered by 24 VAC power. 
To wire the Comfort Control for AC 
power, connect the common side of 
the cooling transformer to the “B”  
terminal as shown at left.
Important: Remove R/Rc jumper for  
2-transformer systems only. (See wiring 
diagram on page 5.)
Connect common side of transformer to “B” terminal
Install batteries in back of thermostat (optional if AC powered).
Battery Backup Power
The Comfort Control can be powered 
by backup batteries when used with 
AC power. During power interruptions 
the batteries will save time/day set-
tings and power the display.
After installation, batteries can be 
changed without removing the 
Comfort Control from the wall  
(see page 10).
To Mount Comfort Control
Align the 4 tabs on the wallplate 
with corresponding slots on the 
back of the Comfort Control, then 
push gently until the Comfort 
Control snaps in place.
