EPH 4 channel controller doesn’t seem to turn on the zone for the hot water occasionally. The zone button on the controller lights up but the valve doesn’t turn or light up. Turning off the other zones seems to get it working properly. I don’t hear the audible Click (from panel) for my water heating zone unless it’s the only zone turned on, and the remaining buttons get brighter when I turn off the water heating zone. Is it possible I have a power supply issue to my panel or that whatever internal relays are in it are beginning to get faulty?
Has anyone ever seen this zone controller give issues as described?
