I have a failed Reliance blending valve on my UFH manifold that is still awaiting it's replacement. but the issue is with protecting the screed floor.
I have a Honeywell overheat switch sat on the manifold set at 60* and wired to stop the pump in over temperature condition.
The problem is the boiler pump when heating DHW pumps water around the UFH circuits at 80*.
If I wire the overheat switch into the motorized valve then the UFH will cycle as the circuit water temp falls.
Whats the solution?
Thanks
