Hello

I'm after some help adding UFH to an EVOHOME system. The system has ATC928G3000 evohome Wi-Fi Connected Controller and Hot water Kit together with 9 zones, all with HR92 Radiator Controllers.

I'm adding HCC80R Underfloor Heating Controller with 2 x T87RF2033 Wireless Thermostat and will use the Controller as another Zone to create 3 new zones.

On the HCC80R Controller Zones, I need to add Zone 1 (3 activators) & Zone 2 (2 activators) together to form a new Zone with temperature controlled by the System Controller. Zone 3 (1 activator) and Zone 4 (1 activator) will each be temperature controlled by T87RF2033 stats.

Is there a step-by-step guide to do this?

Many thanks

The HCC80R Controller comes with a step by step installation & setup manual, which is quite good. The thing to remember is that the thermostats communicate directly with the main controller and not with the HCC80R. I have a similar setup with a mix of rads and UF zones. The HCC80R will directly control the UF pump and the UF motorised valve, which in turn calls for boiler heat independently of the rads.
Hope this helps.
