Minimum Run Time

This feature establishes the minimum allowable run time for the compressor. The minimum run time prevents short run time and lengthens the life of the compressor. The compressor will continue to run for the specified number of minutes even if the set point is reached.
Minimum run time is the number of seconds the thermostat will call for heating or cooling to ensure a comfortable cycling rate. Setting the System to Off or the opposite system call will override the timer and immediately terminate the heating or cooling call.
The minimum run time (MRT) upper limit is tied to the Stage Delay Timer (SDT) setting (600s or 10min by default). The upper limit for MRT may be set as high as 90 minutes, if the SDT is set accordingly.

Latching

This feature establishes how the HVAC Equipment will stage down. If the unit possess multiple stages of heating or cooling, the ability of controlling the stage down process can be beneficial. With this feature disabled, once the set point is met, the thermostat will stage down to the previous stage. After the stage delay, if the set point is still satisfied, the thermostat will stage down once again. With this feature enabled, once the set point has been satisfied, all stages will be turned off and the thermostat will go into standby mode.

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).

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

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.
