We get huge amounts of solar gain.

I had the Maduka room thermostat installed in the sunniest room to act as a limiter if we start to overheat.

We are running on WC and have set the thermostat to 22c. So if we go above 23.5c I'd expect the HP to shutdown.

On low solar gain days the house ticks along 24/7 around 21c constant. Perfect.

Today we have hit 26.5c on the thermostat, the whole house is very toasty and I expected the HP to shut down, but it hasn't.

What settings might need changing so the thermostat does it's job?

Thanks.

You can try adjusting the Modulation & Overshoot settings in the MMI to start with. Enter installer mode to adjust these.

@radwhisperer And, in case you are unaware, to enter installer mode, you need to enter 5678 as the code. Toodles.
