Temperature Cycle Control
The heat and cool cycling rate, expressed in cycles per hour (CPH), indicates how often heating or cooling
system is turned on when temperature is within the temperature differential from the setpoint (which is 1°F
[0.5°C]). There are ten options (1–10) for heat stages and five options (1–5) for cool stages. The number
selected is the maximum number of times the stage is cycled in 1 hour.
For example, when the system is set to 5 CPH, it runs at 12-minute cycles with variable duty cycle.
Depending on the heating or cooling load, which is measured by feedback from the sensor thermistor and/
or temperature error, the system could run at 50% duty cycle (6 minutes ON and 6 minutes OFF), 80%
duty cycle (9.6 minutes ON and 2.4 minutes OFF), or other variations of the duty cycle.
Note: The cycling rate described above is active only when the temperature is within the temperature
differential. If the temperature is outside of the temperature, the heating and cooling equipment
will either be fully ON or fully OFF accordingly.
The following figures show cycling control and includes general notes, if applicable, about each type of
cool or heat system.
Important: There is a built-in compressor protection delay. The delay guarantees a minimum of 5
minutes between compressor cycling ON/OFF. This built-in delay is added to a
configurable additional delay of 0 to 5 minutes as setup in Option Number 0182. The
minimum delay will be between 5 and 10 minutes.
