CAUTION
!
Disconnect power supply before connecting wiring.
Failure to do so may cause equipment damage.
3.
Installer must be a trained, experienced service techni-
cian.
4.
After installation is complete, check out product opera-
tion as provided in these instructions.
3.
Make sure there is good air circulation at average
temperature at the chosen location. Avoid the following
locations because they can introduce errors in sensor
measurements. See Fig. 2.
a. Hot areas caused by:
(i)
Concealed pipes or ducts.
(ii) Drafts from fireplaces or other heat
sources.
(iii) Convection or radiant heat from the sun
or electrical equipment.
b. Cold areas caused by:
(i)
Concealed pipes or ducts.
(ii) Drafts from windows and doors.
(iii) Unheated areas on the other side of the
wall location.
c.
Dead air areas:
(i)
Behind doors, furniture and curtains.
(ii) In corners and alcoves.
4. Remove remote indoor sensor cover by grasping the cover at
the top and the bottom and gently pulling it straight off
the subbase. Position and level the subbase (for appear-
ance only). Device functions correctly even when not level.
5. Use a pencil to mark the wiring opening hole. Remove the
subbase from the wall and drill one hole in the wall for
the wiring opening.
6. Run wire cable to the wiring opening hole at the selected
wall location. Pull approximately three inches of wire
through the wiring opening in the wall. 18-gauge thermo-
stat wire is recommended.
7. Position and level the subbase on the wall with the thermo-
stat wire protruding through the wiring opening hole of
the subbase. Slide the subbase a short distance up the
wall until the thermostat wire rests against the bottom
Location and Mounting (Fig. 2)

CAUTION
!
If the Remote Indoor Temperature Sensor fails, control
reverts to the on-board temperature sensor. Therefore, the
Comfort Control must be installed in the conditioned space.
1.
Choose a location for mounting the Sensor on an inside
wall about 5 ft. (1.5m) above the floor.
2.
Be sure cable distance between the Sensor and
the Comfort Control is less than 200 feet.
