HVAC Equipment Cycling Too Much

in Thermostat HVAC and Wiring

Why does HōlHōm seem to turn my equipment on more frequently than my old thermostat?

HōlHōm’s thermostat is optimized to maximize your comfort by keeping the temperature as close as possible to your target temperature.  This means it may run more often for a shorter time than an older thermostat.

Your heating and cooling equipment is designed to cycle on and off within limits and in all cases, minimum on and off times are respected to prevent damaging your equipment.  By default HōlHōm is set to cycle your heating equipment up to six times per hour and your cooling equipment up to four times per hour.  In addition, by default HōlHōm will not turn your heating equipment on or off for less than 3 minutes and your cooling equipment for less than 4 minutes to prevent damage.

If you reduce the number of cycles per hour, your temperatures are likely to be higher or lower than the target temperature more often.
