To prevent electrical shock

and/or equipment damage,

disconnect electric power to

system at main fuse or

circuit breaker box until

installation is complete.

NOTENOTE

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

use on a line voltage system.

OLD THERMOSTATOLD THERMOSTAT

OLD THERMOSTAT

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.

INSTALLATIONINSTALLATION

ATTACH BASE TO WALLATTACH BASE TO WALL

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.

MULTI-STAGE TERMINAL OUTPUTSMULTI-STAGE TERMINAL OUTPUTS

MULTI-STAGE TERMINAL OUTPUTS

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.
