hey @ScottishGasMan thanks for the reply. I do have 10 actuators sitting in my garage that came with the UFH it seems but was never installed by the property developer. Would i need to get them installed and have room thermostats for those specific rooms? the rads upstairs all have TRV's.
Hi,
I have conflicting information from 2 different plumbers/Viessmann itself and not sure what is correct. My system is a Viessmann vitodens 222-f which powers UFH downstairs and rads upstairs.
We have no internal thermostats anywhere in the house and just work off of the weather compensator...
