Installing Wallplate
CAUTION
Electrical Hazard.
Can cause electrical shock or equipment
damage.
Disconnect power before wiring.
The comfort control can be mounted horizontally on the
wall or on a 4 in. x 2 in. (101.6 mm x 50.8 mm) wiring box.
1. Position and level the wallplate (for appearance
only).
2. Use a pencil to mark the mounting holes.
Fig. 2. Mounting wallplate.
3. Remove the wallplate from the wall and, if drywall,
drill two 3/16-in. holes in the wall, as marked. For
firmer material such as plaster, drill two 7/32-in.
holes. Gently tap anchors (provided) into the drilled
holes until flush with the wall.
4. Position the wallplate over the holes, pulling wires
through the wiring opening. See Fig. 2.
5. Insert the mounting screws into the holes and
tighten.
WIRING (FIG. 5-7)
All wiring must comply with local electrical codes and
ordinances.
1. Select set of terminal identifications (Table 2) that
corresponds with system type (conventional or heat
pump) in Fig. 3.
2. Loosen the screws for the appropriate system type
selected; see Table 2. Insert wires in the terminal
block under the loosened screw. See Fig. 4.
3. Securely tighten each screw.
4. Push excess wire back into the hole.
5. Plug the hole with nonflammable insulation to pre-
vent drafts from affecting the comfort control.
Fig. 3. Selecting terminal identifications for
system type.
NOTE: The factory default setting is configured for a
1 heat/1cool system with a gas furnace.

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 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.
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.
Fig. 8. Installing batteries on comfort control back.
Mounting the Comfort Control
1. Align the terminal screw blocks with the pins on the
back of the comfort control.
2. Push the comfort control straight onto the wallplate.
See Fig. 9.
Fig. 9. Mounting comfort control on wallplate.
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.
Fig. 10. Removing tab to activate real-time clock.
This comfort control is designed to automatically keep
current time and day in memory for up to ten years under
normal use after calendar is set. When comfort control is
first powered, display is ready to enter calendar date. See
Fig. 11.
