WARNING:
- Always turn off power at main fuse or circuit breaker panel before installing, removing, cleaning, or servicing thermostat.
- Read all the information in this manual before installing this thermostat.
- DO NOT CONNECT TO 120 VAC. This is a 24 VAC low-voltage thermostat. Do not install on voltages higher than 30 VAC.
- 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.
Step 1: Replacing Existing Thermostat
- Turn off power to heating and cooling system.
- Remove cover from old thermostat to expose wires (Figure 1).
- Disconnect wires one at a time from existing terminals. Use enclosed labels to mark existing wires. Refer to cross references in the Wiring Table if existing wiring does not directly match the labels.
| Old Terminal | New Label | Description |
| R, V-VR or VR-R | R | 24VAC, return |
| Y, Y1, M | Y1 | Compressor relay (Stage 1) |
| O or R | O | Reversing valve (cool active) |
| B | B | Reversing valve (heat active) |
| F or G | G | Fan control relay |
| Y2 | Y2 | 2nd stage cooling circuit |
| W2, W-U or E | W2/E | 2nd stage heating control or emergency heating for heat pumps |
| C, X or B | C | 24 VAC, transformer common side |
| L or X | L | System monitor |
| W or W1 | W1 | 1st stage heat – non heat pump |
Step 2: Installing Model 9560 Thermostat
- Turn power off to the heating and cooling systems.
- Place EMER-HEAT-OFF-COOL in OFF position .
- Place
AUTO-ON switch into AUTO position
- Remove the cover using a coin or screwdriver Set aside
- Place the thermostat against the wall at desired location. Make sure wires will feed through opening (Figure 4) on base of thermostat.
- Mark placement of mounting holes Set base aside.
- If mounting on drywall, tap plastic anchors into wall.
- NOTE: Enclosed plastic anchors do not require a drilled hole for drywall.
- If mounting on a surface other than drywall, drill the marked holes using a 3/16″ (5mm) drill bit.
- Align base with plastic anchors and feed wires through opening.
- Secure base to wall with supplied screws. NOTE: The thermostat will mount horizontally on a single gang junction box.
- Strip end of wires 5/16” (8mm) if needed.
- Terminal screws are already loose and ready for wire insertion.
- Insert wires into terminal strip (Figure 4) matching the label to the corresponding terminal (see Wiring Diagrams). Tighten screws.
- Make sure wire connections are secure.
- Push excess wire back through opening

- A temperature limiting jumper has been included in this thermostat.
- Cutting this jumper (J3) limits the heating setpoint to no greater than 72°F and the cooling setpoint to no lower than 78°F (Figure 7).
- Replace thermostat cover by snapping into place.
Testing the Thermostat
- Place the AUTO-HEAT-OFF-COOL switch into the COOL position.
- 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.
- Put the AUTO-HEAT-OFF-COOL switch into the OFF position. The air conditioning system should turn off.
- Put the AUTO-HEAT-OFF-COOL switch into the HEAT position.
- 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. - Put the AUTO-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.
- Put the
ON-AUTO switch into the ON position. The blower fan should turn on.
- put the ON-AUTO switch into the AUTO position. The blower fan should turn off.
Customizing the Thermostat
System
- Cool: The thermostat controls the cooling.
- Off: The heating and cooling systems are off.
- Heat: The thermostat controls the heat.
- Emer:The thermostat controls the second stage emergency heat. Use only when the primary stage of heat is not functioning or requires service.
- The display will show CHECK HP when the heat pump requires service
Fan
- Auto: Equipment controls the fan.
- On: The fan operates continuously.
Temperature Differential and Deadband
The temperature differential is factory set at 1°F (0.5°C) for the 1ST stage differential and 2°F (1.0°C) for the 2ND stage. This means that whenever the room temperature changes by one degree Fahrenheit from the temperature setting, the system will turn on. If the system turns on too often, increase the temperature differential. The 2ND stage will turn on when the room temperature changes from the desired temperature by the sum of the 1ST and 2ND stage differential settings. The 2ND stage will also turn on if the temperature has not increased (or decreased in the event of cooling) for a period of twenty minutes. Although programmed at the same time as the temperature differentials, the deadband is used only during the AUTO mode. In the AUTO mode, the thermostat will automatically cycle either the heating or cooling system to maintain optimal comfort. The deadband is the minimum allowable temperature which must occur to switch to the opposite mode. For example, if the deadband is set at 3°F and the setpoint is set at 70°F, the thermostat will switch to cooling mode when the temperature reaches 73°F.

LED Indicators
The Robertshaw 9560 uses three LED indicators (in addition to icons on the LCD display) to indicate functionality of the thermostat. When illuminated, the right red LED indicates that the thermostat is calling for emergency heat. The left green LED indicates a call for auxiliary cool. When the middle amber LED is illuminated, the system is not functioning. Call your local HVACR service contractor.
Backlit Display
This thermostat is equipped with a backlight to make nighttime temperature adjustments quick and easy. Press the button to activate the backlight. The backlight will turn off after about 15 seconds of inactivity.
Emergency Heat
The Emergency Heat switch is located on the bottom right corner. To activate emergency heat, slide switch from NORMAL to EMER HEAT.
Reset
To reset the thermostat to factory preprogrammed conditions, press the RESET button located beneath the lower left corner of the display.
Troubleshooting
| Symptom | Remedy |
| Thermostat does not turn on system. | Check wiring (see Installation
section). |
| Thermostat turns system on and off too frequently. | Increase temperature differential (see Changing the Temperature Differential section). |
