How to wire a zone valve on a boiler.

Now, for the zone valves to signal the boiler there is a call for heat, you need to wire in terminals 2 and 3 on the valve. Your boiler has "TT" terminals. One "T" is 24VAC and the other is common. Once you know which one is 24VAC (check with a voltmeter), that T attaches to Terminal 3. DO NOT ATTACH 24VAC TO TERMINAL 2.Step 5 - Removing the Zone Valve. The zone valve will be bolted onto the pipe. When it's safe to do so, the zone valve can simply be unbolted and removed from the line of pipe. Be careful when doing this because the valve can stay hot for some time, even when the boiler is shut off. Use the screwdriver to remove the electrical connections from ...Learn how to fix your hydronic heating by changing the zone valve motor with this easy tutorial. Watch the video and save money on repairs.The system has a one zone Taco switching relay and five Taco zone valves. BTW, the thing works great. So on a call for heat I would assume that the zone valve opens and the secondary circulator starts up directly. But this doesn't seem to be the case. The valve opens but the secondary circulator doesn't come on.

Consider that the zone valve is nothing more than a mechanical water flow valve on a loop of hot water heating pipe that. 1. responds to a thermostat's call for heat. 2. opens to allow hot water to flow through the zone. 3. turns on the circulator pump once the valve is open.

ZONE VALVES 1 Patent Pending CAUTION 1. Disconnect power supply before connecting wiring to prevent electrical shock or equipment damage. 2. Normally it is not necessary to remove the actuator from the valve body during installation. If the valve must be disassembled, be certain that it is reassembled with the water flow in the direction of the ...The load is now a boiler. (See Figure 4, page 20.) This wiring diagram shows 120 V coming from L1 of a circuit breaker, through a switch, powering a boiler control and returning through L2, back to the neutral bar of the circuit breaker box. This is fine if the boiler is 120 V. However, most gas boilers you will be working on have 24-V controls.
