WARNING:

•Always turn off power at the main power source by unscrewing

fuse or switching circuit breaker to the off position before installing,

removing, cleaning, or servicing thermostat.

•Read all of the information in this manual before installing or

programming this thermostat.

•DO NOT CONNECT TO 120 VAC. This is a 24V AC low voltage ther-

mostat. Do not install on voltages higher than 30V AC.

•All wiring must conform to local and national building and electrical

codes and ordinances.

•Do not short (jumper) across terminals on the gas valve or at the

system control to test installation. This will damage the thermostat

and void the warranty.

•Do not connect ground to any terminal in this unit.

Recycling Thermostat

If this thermostat REPLACES a thermostat that contains mercury,

DO NOT discard the old thermostat in the regular trash. Mercury

is harmful to humans and the environment. For this reason, do

not open, break, or crush the mercury cell. If mercury leaks from

a damaged cell, DO NOT touch or handle mercury with bare

hands. Use protective, non-absorbent gloves to place mercury

into a sealable container. Fill the container with sand or another

absorbent material and seal the container completely.

Return the mercury or mercury products, in a sealed container, to

Invensys Controls Americas or a local recycling center for proper

disposal. If you have any questions, call Robertshaw technical

support at 1-800-445-8299.

WARNING:

In heat pump applications, do not connect anything to the W1

terminal. When switched to HP mode, W1 is connected internally

to Y1 on the thermostat.

1. Turn off power to heating and cooling system.

2. Remove cover of old thermostat to expose wires. Do not

disconnect wires. (See Figure 1)

3. Label wires per the Wiring Table.

4. After labeling wires, remove wires from terminals.

5. Remove existing thermostat base from wall.

6. Refer to the following section for instructions on how to

install thermostat.

Figure 1

Installing Item C8601 Thermostat

NOTE: FOR NEW INSTALLATIONS, MOUNT THERMOSTAT ON AN INSIDE WALL, 4-5 FEET

ABOVE THE FLOOR. DO NOT INSTALL BEHIND A DOOR, IN A CORNER, NEAR AIR VENTS,

IN DIRECT SUNLIGHT, OR NEAR ANY HEAT OR STEAM GENERATING FIXTURES. INSTALLATION

AT THESE PLACES WILL AFFECT THERMOSTAT OPERATION.

9. Align base with plastic anchors and feed wires through opening

(see Figure 3).

10. Secure base to wall with supplied screws.

11. Connect wires to terminal strip. Refer to wiring diagrams on page 5.

Make sure wire connections are secure.

12. Place Electric/Gas switch into either the ELEC or GAS position

depending on the type of furnace (see Figure 3).

13. Place the HP option switch into either the NON_HP or HP position

depending on the type of system you are using (see Figure 3). Use

the HP position for heat pumps ONLY. Use the NON_HP setting for

everything else.

14. Replace cover on thermostat by snapping into place.

15. Turn on power to system. Test thermostat as described in the
