3. Remove the thermostat cover from wall plate (mount-
ing base) to expose mounting holes. See Fig. 1.
4. Route thermostat wires through large hole in mount-
ing base. Remove outer sheath from wires for added
flexibility. Standard solid or multi-conductor thermo-
stat wire should be used from the thermostat to the
unit. Size and length considerations are as fol-
lows: for a maximum distance from unit of 36 ft,
use 22 AWG (American Wire Gage) wire; for a maxi-
mum distance from unit of 100 ft, use 18 AWG wire.
5. Level mounting base against wall and mark wall through
the 2 mounting holes in base.
6. Drill two 3 ⁄ -in. mounting holes in wall where marked.

WARNING: Be careful not to drill into wiring in wall.
Electrical shock could result.
7. Secure mounting base to wall with 2 screws and an-
chors provided. Ensure all wires exit through hole in
mounting base.
8. Adjust wire length and routing to allow proper closure
of the thermostat. Strip each wire at the end no more
than 1 ⁄ -in. to prevent adjacent wires from shorting to-
4
gether. Match and connect wires to terminals on the
thermostat. See Fig. 2-7 and Table 1.
CAUTION: Improper wiring or installation may cause
damage to the thermostat. Check to ensure wiring is
correct before proceeding with installation of unit.
9. Push excess wiring into wall. Seal hole in wall to pre-
vent drafts.
10. Re-attach thermostat cover to back plate.
11. Turn on power to unit. The thermostat will receive power
from the unit. The thermostat will be powered by 24 v,
nominal (18 to 30 vac). Terminals R (+ 24 v), W1/O/B
(first stage heat or reversing valve), Y1 (first stage cool-
ing), and G (fan relay) will always be connected. Some
applications will use C (common), Y2 (second stage cool-
ing), or W2 (second stage heating).
