We have a new 11.2 kW Ecodan ASHP and all UFH in concrete floors in a large well insulated house.

I started with Weather Compensation and was satisfied, with little cycling, but decided to try Advanced Auto Adaptation extending the cable from the little FTC box, moving it into the living room. It is working great, using low power and no cycling. The only con is that as there is no connection from the existing house thermostats to the FTC, I have to keep the living room thermostat set the same as the FTC thermostat so they switch off at the same time when the room temperature target is reached, otherwise the UFH pump will run unnecessarily, although it doesn't use a lot of power.

I now intend to order a Mitsubishi wireless controller and receiver (£167).

Any comments?

Think if you read the manual it says auto adaption is for radiators, but if you have a very thin screed if should work ok. Once you hit a cold spell make sure the room temperature doesn't start to yo-yo up and down
