Easy to install, simple wiring works well.
I replace a Taco ZVC406-4 with this that was controlling 4 valves and 2 pumps on a single circuit which had stopped activating the pumps. The install was way easier and totally straightforward. The price was also favourable. Works great.

Easier than a Taco
The supply houses here all sell Taco control boxes, but I have had many fail recently so I decided to try another brand. The Tekmars are easier to wire because you don't have to connect the transformers or run a hot wire to the pump end switch. Only time will tell if they last as long or longer. The price at Pexuniverse is also reasonable.

what is different between 306V and 306P? Which one I should choose if I have 2 zone with 2 pump, 1pump for 1st floor radiant heat and 1pump for basement baseboard. Thank you.
Helpful? Yes 1 No
306V is a zone valve control. 306P is a circulator switching relay. Since you're zoning with circulator pumps, you would need a switching relay. All the switching relays we sell are universal and work with all brands of circulators - whether it's Taco, Grundfos, Armstrong, Wilo or any other.
