honeywell evohome + ufh

[cheradenine]

Hi

I have a honeywell evohome installation that uses HR92 TRVs on ordinary radiators. Works well, I like.

Kitchen/Dining room extension in progress. ~45m^2. Am going to install UFH. Probably single zone. I would like to integrate with evohome. I am confused by what products I would need to do this.

I *think* it's a case of
1x HM 80 UNIVERSAL MIXING VALVE CONTROLLER
1x thermostat (e.g DTS92) ?

Sound right?

You need an HCC80R Underfloor heating controller and Honeywell actuators, and a thermostat

One manifold/control zone will just need a single zone thermostat and BDR.

The HCC80 is overkill fro anything below 3 control zones and can be replicated with BDRs and a pump relay. Only the 30cm rule becomes a pain.

DTS92 plus a BDR91 attached to the pump ?

Would there be any advantage to the HM80, or is it completely unneccessary?

Its not unecessary, and adds finer control, but you need a rotary valve instead of a thermostatic blending valve which adds to the cost.

Not that hard to install for someone used to dealing with them.
