◆ 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.
