Added a heat exchanger to back up my heat pump water heater.

Item is fine. Return policy is not because they never mention the 20% restocking fee until AFTER you return the item. It comes as a complete surprise. Sneaky? You bet.

I replaced an older generation of this unit with this one. The older one had mechanical relays ,this one appears to have solid state switching. The unit is wider than the old one

Tells you when power is on and when the zone is calling. Could use more zone capability.

I replaced an older generation of this unit with this one... Works very well, hopefully will last better than the previous generation units.
