Background, Buderus system mixed Radiant in Floor basement and first floor, baseboard 2nd floor. I have three Zonetrak units each controlling three or more zones. One Zone Control unit is not giving power to one of the zone thermostats. If I manually click the button the relay works and the circ tied to that zone turns on. I switched the thermostat out and that was not it. These things are fairly simple but I dont want to have to replace an entire board. Any ideas? TIA
I checked that last night and there is power there! Went back to the thermostat no power. After checking around I found a second thermoststat in the next small room with the same problem. So now we have master bedroom and master bathroom same problem. I never noticed before but there is only one zone control solenoid for the Master Suite which has two thermostats! Now I gather that the two Pop Top Control Valves underneath the master suite control where the flow goes and they are both pushed by that single circ tied back to that single solenoid. Now, there are two control valves there, both appear different and there’s like 5 or 6 sets of dual thermostat wires in there so now I need to figure that out.
