B. The DIGICOM / DIGIHP thermostat shall determine the heating or cooling demand based upon the programmed set points and space temperature deviation.
C. When the room ambient is equal to or greater than a 2.0 F. deviation from the thermostat set point, the thermostat will energize the first stage of that specific mode.
D. Upon a continued set point deviation of 3.0 F. or greater, the second stage of the specific mode will be energized. When the demand recovers to 2.0 F. or less from set point, the second stage is released. When the demand recovers to 1.0 F. or less from set point, the first stage is released.
1. DIGIHP heat pump thermostat only: When the room ambient is 4.0 F or greater from the thermostat set point, the thermostat will energize the third heat stage. When the demand recovers to within 3.0 F. from set point, the stage will be released.
