“Love it easy to install I can see it saving me a lot of money very nice unit I bought the 4 zone the price difference was only a few $ and in case I ad a zone or one of the zones on it goes bad I have back up”
“Works Better than I expected. 4stars because Could use a schematic of the relays. Although I was able to figure it out it would not be easy for the everyday DIYer. I Used this to control the zone valves in my hydronic heated floors. And a hot water circulation loop. Works great.”
“Used this to eliminate the rats nest the original installer had made with the control wiring. Also needed the isolation contacts for the aquastat connection due to a new thermostat.”
