The Efficient Home Forum

I have tested my system during normal operation (mode auto - I'm at home) and I've noticed that when the DWH is off and the heating is ON then the water temp drops and the water of the heating system does not go flow into the DWH system so I think that my 3-way valve is fine.

I think the reason of ...

The time is set to be received by the Wi-Fi and my home wifi is set correctly. The evohome is correctly connected to the Internet.

interesting fact: this issue started to appear exactly ...

I've moved the BDR91 and now the error is gone.

In the setup on the evohome controller, I've selected a 3-way valve. Evohome then asked me to bind with the hot water actuator a BDR91A connected to the CS92 sensor and my existing heating actuator BDR91A ...

Thanks a lot. it worked.
