I've got a small thermostatically controlled Holmes electric heater I bought from WalMart several years ago. It's a dual watt type--you can select low or high power on it. I use it on low power (750 watts) on a seperate circuit then my lights. It's never caused a problem. I set it at 65 degrees F. so it will come on when the lights turn off during the night cycle. I have a tiny grow room--2.5' wide X 5' long X 5' high. Never had a problem with the heater. I also have a TMP-1 CAP thermostat to turn on the intake cooling air at about 80 degrees and the CAP TMP-1 thermostat shuts off the cooling air at about 75 degrees.
The Holmes heater is shutting off by itself now. The selected temperature (65 degrees) light goes off with no temperature selected. That means the unit is in standby and wont come on automatically. This is the first time this has happened (the last couple of days). Should I turn my room temps down closer to 70 to 75 degrees because the Holmes unit thinks an overheat occured (+15 degrees higher then the selected heater temp of 65 degrees) or do you think the unit is trashed and needs to be replaced?
