Vaillant AroTherm Plus 7kW
Posted by: @scalextrix@judith we had a thermostat fitted for the kitchen as there is a lot of solar gain, and it seems to have stopped that function.
I'm not really bothered though.
If the thermostat is connected to the call for heat terminal on the vaillant or myson then I suspect it's also a call for cool (IE an 'enable'). If you turn it to max it will probably override.
4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.

In summary, the Vaillant 7kW heat pump is a mostly well-designed unit with a user-friendly and flexible control interface that operates cost-effectively, at least in my setup. The increase in noise during certain circumstances, particularly during defrost recovery, is disappointing, though it can be managed by scheduling noise reduction mode. Vaillant’s tech support has been very helpful, unlike some competitors who either refer you to your installer or refuse to answer questions altogether.
Thank you, watson did allow me to find this one!
Our experience with Vaillant installers is that they are knowledgeable. We had a relatively low rate of chancers at the pre-survey stage.
