Page Title To actually adjust a thermostat for a radiant floor heating system do not use any set backs for at least two weeks after beginning to find your comfort settings. Start by setting the thermostat at 67 F. and allow the area to run for at least 24 hours before adjusting, now change the setting 1 up or down and wait another 24 hours before adjusting again. Remember you are adjusting for the cold periods of the day.
Many people become confused by the warm periods of the day.
Certain areas such as a room with large amounts of glass can benefit from a setback thermostat by taking a setback one to two hours before the sun begins to heat that area. Wait until you have mastered this method before adjusting for a setback.
