I have what I hope is a possible thermostat setup (see attached image). Can anyone tell me if they think this could be setup (note I have an old Raypak boiler (25-30 years?) with a single common wire). I’m wanting the circulator to always be on in the basement zone but only want the boiler on when the basement is calling for heat. But then I also want the upstairs to be able to call for heat but it needs to turn on it’s circulator AND the boiler... again, possible? You tell me
