Question about Intermatic ET100C Energy Controls - Electronic Time Switches - 24 Hour Elec
It is a 2 zone HWT system. In the summer 1 zone would not shut down. We disconnected the zone valve, thinking this was the issue, but when we replaced this valve, it and the other valve would not open with a call for heat. I reset the timer box and then it acknowledged the zone valve, but as soon as it opened and it tried to start the pump it shut down. Playing with the timer box, I finally got it to run but it seems to be running wild. Does this box seem to be expired?

I don't think the timer runs on 240 volts does it? You can switch 240, but the timer uses 120 volts to run. You might check the connections and timer clock rating more closely. Also, the 'off' & 'on' trippers are different, make sure you use the right one.

Another option would be to get an electronic timer like the Intermatic P1353 that has 3 circuits on it that you could program to cut on and off at different times. For example, you could have one circuit that controls the pump and turns the pump on, then the second circuit would turn on the booster pump at a set time after the filter pump had come on and then the heater could be set to also run at a preset time after the pump circuit was activated. Since the pump, booster and heater are all 220, it's a straight forward hookup with everything in one timer box.
The lights, as stated before, would be on a separate circuit (110) and have its own timer or photosensitive eye set in line.
