How to wire a zone valve on a boiler - Each zone valve needs a supply line from the transformer, and a control wire from the thermostat. This allows each zone valve to operate independently, but BOTH have to be wired in parallel from the "end switch" to the boiler's "control circuit", gas valve or circulator, depending on whether it is a constant temperature or "on demand" system.

 
There is an end switch connected between terminal #2 & #3 of the zone valve operator. To activate the boiler control we run another wire from #2 terminal to one of the T terminal of the boiler control. We run another wire from the #3 terminal of the zone valve to the other T or TV terminal of the boiler control.. Gas prices in victorville ca

A 3-way mixing valve, built-in to achieve the low-temperature level of the under floor heating circuit, is controlled by an accessory kit for a heating circuit with a mixing valve. IMPORTANT. System separation is required of underfloor heating systems employing non-oxygen diffusion barrier tubing. gas valve, igniter and blower. When a room thermostat calls for heat, the IBC starts the system circulator and blower. The IBC runs the blower to purge the boiler flue passages, then turns on the igniter and lets it warm up. After igniter warm-up, the IBC opens the gas valve, turns the igniter off, and checks for flame.Vitodens with Zone Valves.
