The thermostat is a 12V DC controlled system and is a

bimetal type. It has three (3) switches on the face of the

thermostat. On the left side there is a SYSTEM switch and

on the right side there are two FAN switches. The top switch

if for HI or LOW FAN and the bottom one is for ON or AUTO.

This thermostat will operate an air conditioner and a

furnace.

Verify the wiring is correct.

A 2-conductor cable, 18 to 22 AWG is required for the 12V

DC power source. This can be routed into the system at

either the unit or the thermostat.

Select the shortest direct route between the power supply

and the system. A negative wire must be supplied. Frame

work grounding is not adequate.

At the unit, route both leads from the 12V DC supply and the

four wires from the thermostat up through the plastic

bushing in the bottom left of the electric box for connection.

Or at the thermostat, route both leads from the 12V DC

supply through the wall and behind the thermostat.

Route the four wires from the thermostat up through the

plastic bushing in the bottom left of the electric box for

connection.

For furnace hookup or use of another thermostat, consult

the installation instructions provided with the furnace and/

or the thermostat. Normally, the furnace will connect to the

RHRH

RH and

W terminals of the thermostat.

There are four low voltage wires in the electric box of the air

conditioner. They are black, yellow, blue and orange. The

black wire goes to negative (–) DC volt power source. The

yellow goes to thermostat Y terminal. The blue goes to

thermostat

H terminal and the orange goes to thermostat

G terminal. The DC volt positive (+) from the power source

goes to thermostat

RCRC

RC terminal. If a furnace is wired to the

heat-cool thermostat, one furnace thermostat wire goes to

terminal

RHRH

RH on the thermostat. The other furnace thermo-

stat wire goes to terminal

W on the thermostat.

To check the thermostat remove all wires. Next, using an

ohm meter, with the SYSTEM switch in the COOL position

and the FAN switches in AUTO and HI and the room

temperature above the setpoint temperature, continuity

should exist between RC to G, RC to Y and RC to H. No

continuity should exist between RH to W. With room

temperature below setpoint temperature, no continuity

would exist between RC to G, RC to Y and RC to H, and RH

to W. With FAN switches in AUTO and LOW, and room
