I have a zsr103. None of the zones are circulating. The thermostats open the valves on each zone when calling for heat, The pumps don't turn on. The output pump fuses are good. I measure 120v at the input, the transformer that's soldered on measures 24v. However, there's no power on LED. also, none of the zone LEDs light up. What do I check next?
Thanks,
Tom
