Hello all, I'm new in this site and I can use all the help I can get from you guys. It'll be appreciated.
My question is that I have a Weil Mclain boiler and currently has one zone for my basement and my first floor. What I like to do is install a seperate thermostate in the basement. Any one know what I need to do this? I've been looking at zone switching relays with zone valves but what I don't understand is how am I going to control the 24 volt gas valve when both of the thermostats are calling for heat. I don't want to fry my gas valve it is a White Rodgers and is expansive. Also do I need to add another circulating pump?
