Comments about 4 Zone Valve Control Module with Priority:

Buy this controller, wiring is a breeze, it controls all zones and DHW. Cost was well worth it's weight. I hope to get many years of use from it. Would highly recommend this product.

Comments about 4 Zone Valve Control Module with Priority:

I purchased a 4-zone relay to consolidate several pump zones onto a common variable-speed circulator. Not a lot one can add to what is said about these ubiquitous Taco controls; they are as advertised and make your wiring jobs neater. Let me re-phrase. You can always do a sloppy wiring job no matter what controls you use. The Taco line removes your bad excuses. :)

Comments about 4 Zone Valve Control Module with Priority:

Broke the house up into a Primary/Secondary Loop
Controlling 3 zone valves with end switches signaling panel when valve is open (I like this feature).
When active, operates secondary loop pump and commands a wall hung boiler on.
Have plans this summer to install same panel in
parents house, maybe with more zones.
No Complaints here on products operation

Wish everything was this simple.

By CBMTTek

Comments about 4 Zone Valve Control Module with Priority:

This unit does exactly what it says it will do. My heating system is three zones, plus an in-floor radiant system. The control wiring for this systems was a maze of cable, relays, and guesswork. Seriously needed replacing.

The Good:
Simple, clean wiring.
Zone indicator lights let you tell at a glance what zone is calling for heat
Includes transformer and relays so that you can bypass your internal boiler controls (if desired)
Simple screw down connections for control and power wiring.
Tech support was very helpful and replied quickly.

The Bad:
The manual could be a bit more clear. Need to review the manual while looking at the circuit board to get the full picture. I actually contacted Taco tech support, then found the information I was looking for printed on the circuit board.
Access holes do not prevent dust from entering unit.

The Ugly:
Working clearances internal to the unit are very tight. Need to be careful about wire routing to ensure a clean install. Ensure and test that power is off before working on unit, even connection of low voltage. 24 volts can kick up quite a few sparks.

  • 4 Zone Valve Control Module with Priority

    Q:

    Will the zone valve control module run circulators instead of zone valves?
    Asked on 6/11/2012 by heatmizer

    • CUSTOMER CARE

      A:

      If you want to control multiple circulator pumps, we would recommend that you use a switching relay, such as a Taco SR504.

      A:

      Well, not really. It's a voltage problem. Zone valves are 24 volt
      and that is what the output of this control module is. A Control set
      up to run circulators puts out 120VAC for each zone and if you have
      multiple circulators you need to get the right control.

      I would just run the thermostat wire to the first actuator and then install jumpers to the second and third thermostat inputs.

      A:

      just wire them in parallel...each acutator has 2 wires that power the actuator and possibly 2 other wires for an "end switch" (but we're not talking about end switches right now)...if the acutator "load" wires are color coded then hook all of one color together which will receive the "heat call" (as well as the heat source, pumps etc) the other actuator wires (hooked together also) get hooked to the 24VAC common wire.

    What do I use the Priority feature for? Can you give me some examples?

      A:

      You would use the priority feature for a Domestic Hot water call. It would
      send the water exclusively to that zone, then when the demand is met, or a
      time limit is exceeded, it would fire the other zones.

      A:

      The priority feature is typically used for an indirect water heater. This
      way all the other zones turn off while the water is being heated to heat
      faster.

    • VERIFIED BUYER

      A:

      When a priority zone "calls", all other zones' "calls" will be disregarded until the priority zone is satisfied.  The priority zone is most often used for DHW (Domestic Hot Water) demands....the thinking being that the spacating will not suffer from a relatively short "off" period while the water heater is allowed to heat up.

      A:

      Normally, no more than three. The key factor is that you do not exceed the maximum allowable amp draw.

      Answered on 7/27/2011 by PexSupply Staff from NY
    • A:

      I recently completed an installation with 16 zones, in my home that I am building. I found that the 24V zone actuators that I am using pulled enough amperage that I was only able to run a single actuator on each zone (otherwise the TACO unit clicks on and then almost immediately clicks off). In some of my larger rooms, I have 3 separate loops with 3 separate zone actuators, so I ended up having to get several TACO zone valve control modules to give me the 16 zones I needed to drive the 16 actuators I have. For rooms with multiple loops I then jumpered the thermostat connections at the top of the circuit board, so only one thermostat would trigger the separate actuators (note: you can only jumper three thermostat sets, otherwise this will overload the transformer and it won't work).
