Hi I have a evohome new ufh system with 2 manifolds and two hce80’s the boiler is at one end of the house the main controller and 1st hce80 are in the middle and the 2nd hce80 is at the opposite end of house to boiler,
The first ufh80 works great, the trouble is with the second one, the controller triggers the zones correctly and actuators work and pump turns on but it doesn’t trigger the boiler relay on any of the zones connected to it.
My question is why? Is the hce80 talking direct to the boiler relay and the distance is too great or is boiler relay triggered from central controller which is what I think is happening. If the latter any ideas why boiler is not triggered from second hce80?
