Page 42: Temperature Cycle Control
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. - Page 43 Temperature Cycle Control Figure 21. Auto heat and cool systems General Notes: • The number of cooling or heating cycles are fixed according to CPH setting value. • The duty cycle is varied during the cycling control. • There are five (5) options for cooling CPH selection and ten (10) options for heating CPH selection.
