5 Zone Valve Control Module with Priority

I used it to control thermal actuators in a 5-zone hydronic heating system, instead of for controlling zone valves. It works great and makes wiring easy. Thermal actuators only require 1 watt each of power so the two built-in 24VAC 40watt transformers are overkill for my application, but they would be perfect for a system with zone valves. High quality construction. The electrical connection terminals and sufficient space in the enclosure make it very easy to wire. The control lights showing when each zone thermostat is calling for heat (yellow) and then when zone pump is switched on (red) are highly visible and and allow easy monitoring of the system. It is also cheaper than other zone controllers. Note: There was already an external 24VAC transformer installed for the system so I fed it into this controller and am not using the included two internal transformers. This allowed me to skip wiring the controller to line voltage.

good quality product. easy to install. works fine. price was lower than most other vendors. i reommend both the product and the vendor.

Works as it should

I would buy this again but no need to. Once installed it works flawlessly.

Upgraded from a four zone zvc to a 5. Flawless 13 years out of the 4 zone taco still works perfectly. Expect no less from the new one.

Can't go wrong with taco this board is simple to understand there's no need to dig around in a manual to hook it up

tied in five thermostats and five zone valves. Easy to do and worked perfectly. Could't ask for better functionality. As the unit turns the boiler on with any call for heat, I do not understand why you have to jump two terminals. In my opinion, they should jump it at the factory, and have you remove the jumpers if you are going to use the switch on the zone valve. A very minor nitpick.

Simple installation, redundant transformer, expandable, whats not to like about it?

I bought this as a spare part for my boiler system that is 20 years old, because parts like this are not readily available in remote Wyoming.

The zone valve module worked great made the job look professional. Makes it easy to trouble shoot later on. Price and delivery were fantastic. Thanks you always take care of me.
