Staging Logic

Staging response determines how the thermostat stages heating or cooling calls based on the difference between space temperature and the set point (1.0°F or 1.5°F).

3.1 Staging Timers
There are 4 timers defined in the stage algorithm, MRT (Minimum Run Timer), ASC (Anti-Short Cycle Timer), Stage Delay and a fixed 3 minutes timer for quick staging down.

• When any stage is on, it has to run for the MRT, except in the scenario of quick staging down where the heating/cooling is turned off.
• When any stage is up or down, it has to wait for Stage Delay to expire.
• When all stages are turned off, the system has to wait for ASC to expire before it can be turned on again. Please note, the ASC timers run concurrently with Fan off Delay timer defined elsewhere.

Table 1 Stage Timers

3.2 Staging Temp
Stage temperature is use to determine whether there is a need for quick staging up or staging down based on a temperature setpoint differential.
