SIMPLE CONTROL MODULE

Comments about 3 Zone Valve Control Module:

We purchased control valves without end swithches by mistake. The solution was to buy 24 volt relays or somehow install end switches in the valves. This Taco control module solved the problem. All the wiring looks simple and professional.

Comments about 3 Zone Valve Control Module:

Our Lochinvar boiler was, according to the local rep, installed incorrectly in that our zone valves were supplied with 24 VAC from the Auxiliary on the low voltage board. So after a steep bid ($674) came in to install a zone controller for our 2-zone system, I tracked this controller down to install myself. The zone valves are Honeywell (V8043 I believe), and there's even an FAQ note on how to wire it up. The zone controller just sends a "closed" dry contact signal to the boiler, and the boiler takes care of the rest.

Comments about 3 Zone Valve Control Module:

Makes wiring simple and works really well with a primary and secondary system using only two pumps and three valves. However, if you are planning to use pumps and valves then use the model with the relays. It will give you more flexibility. The transformer hums a little bit.

I bought this control to clean up an older system that has a mixture of zone valves, thermostats etc. Works beautifully. Was simple to install and has great system status indicators.

  • 3 Zone Valve Control Module

    Q:

    Can this control module turn pumps on and off or just open and close valves
    Asked on 4/24/2012 by mike from bc

      A:

      The Taco ZVC series zone valve controllers can turn on a pump using the auxiliary contact(s), (there are usually two, some models have three). Typically, if you are using valves (24VAC), you will have a single pump (120VAC). The ZVC allows you to connect the one pump (it can physically be more than one as long as you observe the voltage/current limitations of the relay contacts) so that a call from any connected thermostat will turn on its associated valve. The end switch on the valve then in turn, switches on the pump. The one pump turns on for any of the t'stats. If you have a priority zone, like domestic hot water, there is typically an extra relay output that can do an isolated operation, but the details get more complex in that circumstance. The outputs on the ZVC are 24VAC and limited current, the three zone unit shown is 40 watts I think.
       
      If you are using zone pumps rather than valves, you want to use a Taco (or other brand) pump controller. The Taco series SR-501, 502, etc. allow you to have individual thermostats that turn on their associated pump. When there's a call from any t'stat, its pump will turn on and an auxiliary contact will close allowing the activation of the heat source. Observe which terminals are connected to what and make sure you don't switch 120VAC to a 24VAC input on a heater. That would let out the smoke.
       
      My company has used many of these Taco controls for over ten years and had very few failures or problems.
       
      Good luck!

      It could, if you connected it to the boiler switch.

      A:

      It has an end switch that closes anytime a valve opens. You can use that
      to control a relay to operate your pump.

      A:

      It can turn on a single pump, like a system pump, that would be flowing to
      the zone valves.
      You do that by wiring through the separate end switch.

      It opens the zone valve and energizes the pump.

      Answered on 4/25/2012 by Another PexSupply Customer
    • VERIFIED BUYER

      A:

      When any of the zones "call" for heating, that particular zone valve is energized...once the valve is successfully opened the "end switch" of that valve closes which completes a "signal" circuit back to the zone panel.  Once the zone panel detects that any "end switch" has closed then it will close 2 "normally open" "dry" contacts (just a switch...no power to either side of switch) and open one "normally closed" contact.  One of these "normally open" contacts typically is used to close a "signal" circuit from heat source to alert that heat source that valves are open and it's OK to fire up.  I use the other "normally open" contact to complete a 110V circuit to energize one or two pumps.

      A:

      You would not wire the damper through this control. That should be wired through the boiler's control. This control is for zone valves.

      You can wire actuators in parallel to this unit. Just keep in mind that the transformer is rated for 40 VA.

      A:

      You will need to use a switching relay, such as the Taco SR503-2. Zone valve controls are designed for systems that are zoned using zone valves.

      According to the manufacturer, the unit comes with both transformers because of the load when using 570 series zone valves.
