I have a heater plugged into a temperature controller now. The controller turn the heater off at 78°F and turns on at 77°F. The thermostat on my Eheim heater is set to 80°F, as a backup, in case the temperature controller fails.
With this setup, the thermostats stays closed or "on" 100% of the time. Is this a bad thing for the thermostat? Can it get stuck in the on position from constant contact like this?
I understand that the temperature controller is controlling the temperature. But if it should fail in the on position, and it's been this way for years, does this increase the chance of it getting stuck in the on position?
