incorrect wiring will damage
thermostat and could cause
personal injury and/or
property damage.
Do not use on circuits
exceeding specified voltage.
Higher voltage will damage
thermostat and could cause
shock or fire hazard.

NOTE
Read all instructions
thoroughly before beginning
installation.
Do not exceed ratings shown in the
Specifications section, above. If in
doubt about the electrical ratings of
your heating/cooling system, have it
inspected by a qualified heating and
air conditioning contractor or
licensed electrician.
All wiring must conform to local
and national electrical codes and
ordinances.
This control is a precision instru-
ment, and should be handled
carefully. Rough handling or
distorting components could cause
the control to malfunction.This thermostat is intended for use
with a low voltage system. Do not

Shut off electricity at main fuse or
circuit breaker box until installation
is complete AND the new thermo-
stat is configured properly.
Remove the front cover of the old
thermostat. With wires still attached,
remove wall plate from the wall.
Identify each wire attached to the
thermostat using one of the labels
enclosed with the new thermostat.
Disconnect the wires from the old
thermostat one at a time. DO NOT
let the wires fall back into the wall.
Install the new thermostat using the
following procedures.

ATTACH BASE TO WALL
Remove packing material from the
thermostat. Place fingers of one
hand on the center top and bottom
portion of the thermostat. Grasp the
base in the other hand on top and
bottom center and gently pull
straight out. Forcing or prying on
the thermostat will cause damage to
the unit.
Place the base over the hole in the
wall where the wires come out and
mark mounting hole locations using
the base as a template. Drill 3/16”
pilot holes, and install screw
anchors in the wall.
Run wires through hole in base and
attach base to wall (see fig. 1).

Installation
Insert the wires into the terminals on
the base using the appropriate
wiring diagram and tighten the
terminal screws.

Refer to equipment manufacturers’
instructions for specific system
wiring information.
You can configure the thermostat for
use with either multi-stage electric
heat systems or multi-stage gas
systems. When configured for
electric heat, the Gterminal
(blower/fan) will be energized on a
call for heat.
This thermostat is designed to
operate a single-transformer system.
If you have a two-transformer
system, cut and tape off one
transformer. If transformer safety
circuits are in only one of the
systems, remove the transformer of
the system with NO safety circuits. If
required, replace remaining trans-
former with a 75VA Class II
transformer. After disconnecting one
transformer, the two commons must
be jumpered together.
Use the terminal output information
below to help you wire the thermo-
stat properly for your multi-stage
system. After wiring, see CON-
FIGURATION section for proper
thermostat configuration.
