Installation
Location
The Comfort Control should be mounted approximately 60"
(1.5m) off the floor on an interior partition wall. Never install
the Home Comfort Control on an outside wall.
For proper temperature sensing, avoid mounting the Comfort
Control where it will be exposed to heat radiated from lamps,
sun light, fireplaces or any other radiant heat sources.
Avoid locations close to windows, behind doors or alcoves
with poor air circulation, adjoining outside walls, or doors
that lead to the outside.
Select a location that prevents the Comfort Control from
being directly exposed to air currents from supply registers or
return grills.
Mount the Comfort Control on a section of interior wall that
does not contain hot and cold water pipes or ductwork.
Mounting and Wiring
1. Turn OFF all power to heating and cooling equipment.
2. If an existing thermostat is being replaced:
a. Remove existing thermostat from wall.
b. Disconnect wires from existing thermostat, one at a
time. Be careful not to allow wires to fall back into the
wall.
c. As each wire is disconnected, record wire color and
terminal marking.
d. Discard or recycle old thermostat.
Mercury is a hazardous waste and MUST be managed
properly. If the Comfort Control is replacing a thermostat
that contains mercury in a sealed tube, do not place your
old thermostat in the trash. Contact your local waste
management authority for instructions regarding recycling
and the proper disposal of an old thermostat.

3. Separate the control from the mounting base to expose
mounting holes by pressing the release button A on the
bottom of the control and lift out and up. See Figure 1.
4. Slide the mounting base drawer out to expose all the
mounting holes.
Route control wires through the large hole in mounting
base. Level mounting base against wall (for aesthetic
value only) and mark wall through 2 mounting holes. See
Figure 2.

5. Drill two mounting holes in wall where marked.
6. Secure mounting base to wall with 2 screws (use anchors
provided if needed). Additional mounting holes are
available for more secure mounting if needed.
Make sure all wires extend through hole in mounting
base.
7. Adjust length and routing of each wire to reach proper
terminal on the connector block on mounting base. Strip
only 1/4-in. of insulation from each wire to prevent
adjacent wires from shorting together when connected.
8. Match and connect control wires to proper terminals on the
connector block. See Figures 3-8.
Two 360 ohm resistors (5 watts) are included with this
control. One of them must be installed between the "W" and
"B/C" terminal of the indoor unit low voltage terminal block
regardless of the application.
The control is powered through the loads connected to it. The
second resistor is required between "Y" and "B/C" at the
indoor unit low voltage terminal block if no outdoor unit is
installed or the outdoor unit has a compressor anti-short cycle
timer installed. See Figures 3-8.
9. Push any excess wire back into the wall and seal the hole to
prevent air leaks.
Note: Air leaks in the wall behind the control can cause
improper operation.
10.Check the operation of the mounting base drawer. Verify
that it slides in and out without binding.
11. Reinstall the control on its mounting base by aligning the
control at the top of the mounting base. Swing the control
downward and gently press the bottom of control into
position until latch button A engages. See Figure 1.
12.Turn ON power to the heating and cooling equipment.
