Aquastat problem

JQuk89 Member Posts: 3
I have a Honeywell L8148E aquastat there is voltage between W & B2 but none between W & T,.the owners manual shows something between these two terminals that is marked 1K, is this a resistor?

    You're measuring in the wrong spot. You're lucky they are both low voltage terminals.
    Be careful or you are going to short it, at best.

    Why no voltage on T or TV can not get power to the pilot control.

    It may not be your aquastat, if that unit has a motorized vent damper call a pro.
