Thermostat Cycles Per Hour Radiant Floor Heating

A faster cycle rate provides tighter temperature control and shorter on off cycles.

Thermostat cycles per hour radiant floor heating.

Pid thermostats use a modifiable pulse pwm to the system to regulate room temperatures. Limitations for homes with heat pumps electric resistance heating steam heat and radiant floor heating programmable thermostats are generally not recommended for heat pumps. But if your floor heating system came with the house or you just got a new thermostat and don t have the kilowatt load usage information on hand here s how to find out what it is. For most homes with hot water boilers or steam heating systems the slow heating cycle rate is optimal.

In years past we tried radiant thermostats that did not sense air temp but attempted to sense the radiant feel of the space. The standard for electric heat is nine cycles per hour. We found that some rooms required a 75 f setting for comfort while others required. The result is that the system turns on before the room gets cold and turns off before the room gets hot.

I understand how an adjustable swing temp works and determines how often the cooling and heating system operates depending on whether the swing in 1 2 degree or 1 degree or more from the set point but how does changing the cph in honeywell thermostats change anything. The standard for cast iron radiators and high efficiency furnaces is three cycles per hour 20 minutes per cycle. For most homes with ducted heating and cooling systems the medium setting is optimal. In its cooling mode a heat pump operates like an air conditioner so turning up the thermostat either manually or with a programmable thermostat will save energy and.

For example a thermostat with a 1 degree differential that is set at 70 degrees will turn an air conditioner on at 71 degrees and off at 69 degrees. If your floor heating system is located under tile or stone its wattage should be 15 watts per square foot. The increase the run time like from 5 min per hour to 30 min per hour till the thermostat finds the appropriate cycle rate to maintain room temperature. In real life each room has its own radiant image dependant primarily on whether the thermostat is facing a window or a wall.

Can anyone explain to me cycle rate per hour that honeywell uses in their thermostats. The temperature difference that a thermostat turns on and off a hvac unit is called differential.
