So, I have installed in my shop a hot water infloor heating system. I'm using a water heater to supply it I have wired a transformer to a thermostat and a relay to turn on the circ pump. I'm on my second brand new relay and I'm getting the same result. It works sometimes and sometimes the relay just buzzes loudly and doesn't make contact. Could the thermostat be the issue? It is a digital one and I understand that sometimes there could be a compatibility issue with certain brands.
