WARNING

All Models

Do not use on circuits exceeding speciﬁed voltage. Higher voltage will

damage control and could cause shock or ﬁre hazard.

Do not short out terminals on gas valve or primary control to test. Short or

incorrect wiring will damage thermostat and could cause personal injury

and/or property damage.

A. Remove base from subbase: Loosen the screws on the base and remove.

B. Mount switching subbase: Use the screws provided to mount the subbase or

wallplate to wall (see Fig. 1).

PREPARATIONS

Assemble tools required: power drill, ﬂat blade screwdriver, wire cutter/stripper, level.

C. Attach wires to appropriate terminals:

• For two wire systems (Heat Only or Cool Only). Replace subbase with wall-

plate. If you have a two-wire Heat Only system, attach one wire to R and one to

wire W. If you have a two-wire Cool Only system, attach one wire to R and one to

wire to Y. Tighten any unused terminals securely. (see Fig. 5 and 6).

Failure to follow and read all instructions carefully before installing or operat-

ing this control could cause personal injury and/or property damage.

•

If your system has more than two wires: Use the cross reference chart to

determine correct wire connections. If you have a four-wire heat/cool system leave

the factory installed jumper between RC and RH attached (see Fig 2.). If your sys-

tem has ﬁve wires remove the factory installed jumper between RC and RH (see

Fig 3.).

THERMOSTAT FEATURES

COOL OFF HEAT

•

Electric heat or single stage heat pump systems: These thermostats are

conﬁgured from the factory to operate a heat/cool, fossil fuel (gas, oil, etc.) forced

air system. This is correct for any system that DOES NOT require the thermostat

to energize the fan on a call for heat. If your system is an electric heat or heat-

pump system that REQUIRES the thermostat to turn on the fan on a call for heat,

remove the yellow factory-installed jumper wire from the Y terminal and connect

it to the A terminal. This will allow the thermostat to energize the fan immediately

on a call for heat. If you are unsure if the heating system requires the thermostat

to control the fan, contact a qualiﬁed heating and air conditioning service person.

For single stage heat pump applications (no auxillary heat), install a short jumper

wire (not included) across terminals W and Y. If the system has a reversing valve

connection energized in Cooling, attach it to O. If the system has a reversing valve

connection energized in Heating, attach it to B (see Fig. 4).This thermostat will not

provide multi-stage heating or cooling.

REMOVING OLD THERMOSTAT

D. Mount Thermostat Base: Gently push excess wire back into the wall opening

and plug hole with a ﬁre-resistant material, such as ﬁberglass insulation to prevent

drafts from affecting thermostat operation. Mount the thermostat base to the sub-

base using the three captive screws on the thermostat base. (See Fig. 1) Tighten

the screws securely. Proceed to Step #5.

CAUTION

To prevent electrical shock and/or equipment damage, disconnect electrical pow-

er to the system at the main fuse or circuit breaker until installation is complete.

CAUTION

Before removing wires from old thermostat’s switching subbase, label each wire with

the terminal designation it was removed from.

Take care when securing and routing wires so they do not short to adjacent

terminals or rear of thermostat. Personal injury and/or property damage may

occur.

1. Remove OldThermostat: A standard heat/cool thermostat consists of three basic

parts:

a. The cover, which may be either a snap-on or hinge type.

b. The base, which is removed by loosening all captive screws.

c. The switching subbase, which is removed by unscrewing the mounting

screws that hold it on the wall or adaptor plate.

Terminal Designation

–

Make a note here

of the anticipator setting on the old thermostat for

–

future reference and use in step 5.

The heat anticipator pointer, if adjustable, will be set at one of a series of numbers

representing the current rating of the primary control in your furnace. The number will

be one of the following: .2, .4, .8, etc. or 0.2, 0.4, 0.8, etc.

* These are four-wire, single-transformer systems. Factory installed jumper wire

between the RH and RC terminals must remain in place.
