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. The deadband for auto
changeover is set at 3°F (1.5°C). To change settings:
1. The thermostat is preset to display the temperature in degrees
Fahrenheit (U.S. models) or degrees Celsius (Canadian models). The
temperature display can be changed. Press and hold both the or

differential between 0.5°F - 3°F.
4. Either wait three seconds or press the button. The display will
indicate: DIFFERENTIAL 2ND.
5. The 2nd stage differential is factory set at 2°F (1.5°C). Press either
the or button to adjust the 2nd stage temperature differential
between 1°F - 6°F (1°C - 3°C).
6. Press the or button to adjust the 2nd stage timed differential
between 5 to 40 minutes. Either wait 5 seconds or press the
button.
7. Either wait three seconds or press the button. The display will
indicate: AUTOCHANGE DEADBAND.

◆LED Indicators
The Robertshaw 9560 uses three LED indicators (in addition to icons on
the LCD display) to indicate functionality of the thermostat. When illumi-
nated, the right red LED indicates that the thermostat is calling for emer-
gency 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.
