Robertshaw 8601 PROGRAMMABLE THERMOSTAT

Application
The Robertshaw 8601 is a single-stage thermostat designed to control 24 VAC gas or electric heating and cooling systems or single-stage heat pumps. The 8601 requires a common wire.

Features

• Large backlit display.
• Four preprogrammed ENERGY STAR® setpoints for each day of the week.
• Fahrenheit/Celsius display option.
• Programmable from 45°F (4°C) to 90°F (32°C).
• Accuracy within ± 1 degree.
• Adjustable temperature differential: 1-3 °F (1-1.5°C).
• Separate heating and cooling programs.

WARNING:

• Always turn off power at the main power source by unscrewing fuse or switching the circuit breaker to the off position before installing, removing, cleaning, or servicing the 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 thermostat.
  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.

Replacing Existing Thermostat

Wiring Table

Old Label	New Label	Description
M, W, Rh, Rc R5, V or 5	R	24VAC, hot side
C, X or B	C	24VAC, common side
Y or Y6	Y1	Cooling control
H, W or 4	W1	Heating control
F or G	G	Fan control relay
O	O	Cool active reversing valve
B	B	Heat active reversing valve

NOTE: THIS THERMOSTAT REQUIRES A 24 VAC COMMON WIRE FOR PROPER OPERATION.
NOTE: ON SOME OLDER MODELS, THE C TERMINAL CAN BE EITHER THE COOLING CONTROL OR THE COMMON SIDE OF THE TRANSFORMER. CHECK THE FURNACE WIRING DIAGRAM TO VERIFY C TERMINAL. IF IT IS THE COMMON SIDE OF THE TRANSFORMER, CONNECT TO THE C TERMINAL.

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 the heating and cooling system.
2. Remove the cover of the 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 the existing thermostat base from the wall.
6. Refer to the following section for instructions on how to install a thermostat.

Installing Item 8601 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.

1. Turn the power off to the heating and cooling systems.
2. Place HEAT-OFF-COOL in the OFF position.
3. Place AUTO–ON switch into the AUTO position.
4. Remove the cover using a coin or screwdriver (see Figure 2).
5. Place the thermostat against the wall at the desired location. Make sure wires will feed through the opening on the base of the thermostat.
6. Mark placement of mounting holes (see Figure 3). Set base aside.
7. Drill the marked holes using a 3/16” (5mm) drill bit.
   NOTE: Enclosed plastic anchors do not require a drilled hole for drywall.
8. Tap plastic anchors into the wall.
9. Align the base with plastic anchors and feed wires through the opening (see Figure 3).
10. Secure base to wall with supplied screws.
11. Connect wires to the terminal strip. Refer to the wiring diagrams on page 5.
    Make sure wire connections are secure.
12. Place the 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 the cover on the thermostat by snapping into place.
15. Turn on the power to the system. Test the thermostat as described in the section To Test Thermostat.

Wiring Diagrams

The following is just a sample of the most common types of HVAC systems. Refer to your system’s installation manual for wiring information.

To Test Thermostat

WARNING: DO NOT SHORT (JUMPER) ACROSS TERMINALS OF GAS VALVE OR SYSTEM CONTROL TO TEST OPERATION. THIS WILL DAMAGE THE THERMOSTAT AND VOID YOUR WARRANTY.
CAUTION: DO NOT SWITCH SYSTEM TO COOL OR LEAVE IN COOL MODE
IF THE TEMPERATURE IS BELOW 50°F (10°C). THIS CAN DAMAGE THE AIR CONDITIONING SYSTEM AND CAUSE PERSONAL INJURY.

1. Place the HEAT-OFF-COOL switch into the COOL position. The will be displayed.
2. Press the button until the temperature setting is at least 3 degrees below the room temperature. The air conditioning system should turn on within a few seconds.
   NOTE: ONCE THE THERMOSTAT TURNS OFF WHEN IN THE COOL MODE, A BUILT-IN 5-MINUTE DELAY PREVENTS THE SYSTEM FROM TURNING ON AGAIN. THIS PROTECTS THE COMPRESSOR. NO ADDITIONAL TIME DELAY RELAY IS REQUIRED. TO OVERRIDE THE 5-MINUTE DELAY FOR INSTALLATION, PRESS THE RESET BUTTON.
3. Put the HEAT-OFF-COOL switch into the OFF position. The air conditioning system should turn off.
4. Put the HEAT-OFF-COOL switch into the HEAT position. The will be displayed.
5. Press the button until the temperature setting is at least 3 degrees above room temperature. The heating system should turn on. The fan may not turn on immediately, depending on the fan delay built into the furnace.
   NOTE: If HP is selected, the heat will not come on until the 5 minute short cycle protection has expired.
6. Put the HEAT-OFF-COOL switch into the OFF position. The heating system should turn off. The fan may continue to run for a short period of time.
7. Put the AUTO-ON switch into the ON position. The blower fan should turn on. The display will show a .
8. Put the AUTO-ON switch into the AUTO position. The blower fan should turn off.
