What is CPH setting?
January 2018. I find that especially with this recent subzero cold, a 1 CPH (cycle per hour) thermostat setting causes a lot of temperature fluctuation and maxes out the radiators each cycle (i.e. they get really really hot).
What is CPH value for cool?
In order to achieve more accurate temperature control, the CPH function enables the thermostat to open the valve several times per hour as the room temperature gets close to the setpoint. The value can be changed in the ISU. The default value is 4 for heating and 3 for cooling.
Why is my thermostat showing auxiliary heat?
What Does It Mean on My Thermostat? If your aux heat indicator is on, it means your heat pump needs a little help reaching its target temperature setting. Aux heat comes from the same heat source as emergency heat, but aux heat works together with your heat pump, so it’s less expensive than emergency heat.
How many times per hour should a heat pump run?
It completely depends on the unit’s cooling capacity, the room temperature and the humidity. On the average, a 10 to 20 minutes shut down should be appropriate enough depending on the factors mentioned. And it should be within 2 to 3 cycles per hour max.
How often should a thermostat cycle?
A typical forced air system will cycle about five times in an hour, this is normal. A typical hot water system would cycle less then that. Every heating system type will deliver heat to the house at a slightly different rate.
How often should AUX heat come on?
When should my auxiliary heat come on? When outside temperatures drop below 40 degrees. While undergoing the defrost cycle. When there is a 3 degree difference or more in the current temperature in your home and the thermostat setting.
Is it bad if auxiliary heat comes on?
It does need to be noted, if your thermostat stays in “Aux Heat” even when temperatures outside rises, you should call to have it serviced. Auxiliary heat uses electric resistance heating, which is much less efficient than your heat pump. Therefore, a heating system stuck in AUX heat will run up an energy bill.
Is it OK for a heat pump to run all night?
If it’s too cold out, your heat pump will work harder – and may run continuously – to pull heat from the outdoor air into your home. So, if the temperatures are below 30° or above 100°, there’s likely nothing wrong with your heat pump.
Why does my heat pump turn on every 10 minutes?
When a heat pump short cycles, it’s having trouble heating or cooling your home. The unit can’t maintain the set temperature, so it restarts over and over again. Whenever your heat pump has a problem, always check your air filter first. Over time, dust and debris form on your filter.
How often should your AC kick on?
Ideally, a properly operating air conditioner should cycle for roughly 15 to 20 minutes, two to three times per hour. If the temperature inside your home is very high, is much higher than the temperature that your thermostat is set at, or the outside temperature is very high, the run time will increase.
