CAUTION

To prevent shortening its service life, the control should not
be installed until construction is completed.

Installation

Comfort Control - Location

The Comfort Control should be mounted approximately 60”
(1.5m) off the floor on an interior partition wall. Never install
the 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.

Mount the Comfort Control on a section of interior wall that
does not contain hot and cold water pipes or ductwork.

Outdoor Sensor - BAYSEN01ATEMPA - Location

Careful consideration of the following recommendations will
help the outdoor sensor provide continuous accurate read-
ings:

1. Mount the outdoor sensor on the north facing side of the

building in an area where it is exposed to freely circulat-
ing airflow and out of direct sunlight.

2. Do not allow hot air airflow from the attic or drafts from

inside exterior walls to bias the sensors operation.
Always seal the hole where control wiring passes to the
outside of the structure. Use non-hardening caulk, putty,
or insulation.

3. Avoid locations such as near dryer vents or placing the

sensor close to, or directly above the outdoor unit where
it would be exposed to hot discharge air from the con-
denser fan.

4. Maximum length of field wiring cable to sensor is 200

feet.

5. Minimum wire gauge is 18AWG.

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 with the thumb of one hand while
gripping the subbase by the mounting holes with the
other hand. 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 (including the 2 outdoor sensor
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.
