The different heating modes are best suited to specific heater types. If you are using a Fan-forced heater, it is recommended that you use Fan-forced mode. You can choose the cycle time for your heater from the three different cycle lengths. If you want your fan to spin less, you should select the Fan-forced long option.
Baseboard mode is for baseboard heaters and is the recommended setting for the most comfort. The radiant mode does not use proportional control and is the recommended setting for radiant heating systems.
