3 wire manual Thermostat to Programed Thermostat?
I have a 3 wire round Honeywell Stat marked R - W - Y terminals and am changing it to a Honeywell RTH2310 programable one. (this is for a oil fired burner only, with zone valves) Wireing schematic calls for Rh-Rc-W-Y-G terminals... where do my wires
Need to know what kind of zone valves you have?---Rick I have sent an inquiry to White Rogers and I waiting for them to respond to it.When they do I will post the info. An answer came back---Tom Martin at HVACPLUS.com says they have a programable thermostat
