Here is my dilemma. I have a 5kw electric heater that I was given. I mounted it and put a double pole line voltage thermostat (Cadet T410B) in line. the problem I am having is the Fan of the unit (which is 110v) runs all the time when the thermostat is in the on position regardless of temperature selected. The heating element is operating fine and only kicks on when it reaches the set temp. I have tried putting the fan power feed wire to the control side and it still runs all the time. I am assuming that it is getting power feed back. If this was a 12v system I would just put an appropriate diode in the system but with AC current I cannot do that. Does anyone have any ideas?
The L2/T2 leads are on anytime the thermostat is in the on position and only breaks when turned to the off position, the L1/T1 leads are thermostatically controlled. if this unit had a 220v motor I would not have any issues but since it has a 110v motor and one side always has power the fan spins. I need either a t-stat that controls both sides (which I cannot seem to find) or some kind of switching device. I am at a loss
