Multiple Evohome controllers

[dty]

Ha! Yes, you're right. What I meant was, having dialled in -3C for this particular rad, and the breakfast area still being 1-2C lower than required, I have no further options but to try and use the setpoint to compensate. And if I do that, it will affect the whole zone.

Does anyone have multiple EvoHome controllers working with OpenTherm?

I’ve just moved into a new house. It has 17 thermostats (!) controlling UFH via 4 manifolds, a few towel radiators and DHW. Vokera Unica OpenTherm LPG boiler.

I think I’ll need two controllers. I miss EvoHome already, unable to monitor temperatures, optimize schedule.

The OTB, like the BDR91 can be paired with up to 4 devices. You simply pair both your Controllers to the same OTB at the boiler. It really is quite clever.
