| wiring zone valves
Hi: Have replaced old cast iron with pex. Kept cast iron radiators (hot water) on first floor. Second floor used fin and tube. Created 2 zones. Original thermostat is two wire, hooked into burner control. This wire was disconnected, and will be wired to one of the zone valves ,White-Rodgers type 1311-102 0743 the other zone will be controlled by a programmable thermostat. It has 3 wires. it is to be connected to a White-Rodgers type 1361-102 0741. I am hooking up a transformer (24v) for the valves. Problem ? The diagram shows 2 wires from the t-stat what do I do with the 3rd wire? How are these connected to the burner control? Diagram shows a T 1 and a T 2, but my controller has just T T. System has been pressure checked (air) but will need to be filled. Can I check that everything is working before firing the boiler. It's 20 degrees outside I don't want to have any freeze ups. |
