I'm still using Evohome since more than 5 years and I'm happy with it.
I'm going to replace my old boiler by an air/water heat pump (Erset C11) that is able to refresh in summer.

I'm also replacing my radiators with a heat floor.
I noticed that the heat floor controller HCC80 is compatible with heating/cooling, and also the single zone thermostat t87rf2 or DT90, but no mention on the evohome controller...

Does anybody knows how it works?

I want also to add in each bedroom radiator with integrated fan to boost the cooling effect, can I control it with the THR92?

Will it work also in cooling or the valve will close and prevent the system to work?

Any help is highly welcomed!
