the thermal storage heaters are typically connected to a control box which in turn is connected to the electric meter. when the meter tells the control box its time to turn on the circuits to the heaters are activated . this is so the heaters use electricity from the night rate. this is sometimes done with an actual timeclock , if so you would want to confirm that the timeclock is set to operate during the nightrate period.
some elctric meters can remember what time it is in the event of a power failure , some not. your utility co. can confirm what you have. if the meter thinks nightrate starts at a different time than the timeclock is set to then you could end up charging the heaters on the day rate , which would cost much more money.
the knobs on top:
one of the controls is for amount of heat stored , one is to control amount released. i think if i remember correctly , the 1-6 knob is how much heat it stores each night.
