Remove the HR92 from the bathroom, then remove the batteries. Wait 20 minutes then re-assemble, put back on and see if it corrects itself?

Have you turned the original analogue thermostat on the hot water tank to max? It may be restricted by the original thermostat.

Help with what? The CS92 is a sensor for the hot water tank. The BDR91 is a wireless relay for the evohome system and its not battery powered.

You need separate BDR91s for HW and CH; so 2.

Have you tried https://international.mytotalconnectcom ... ount/Login?

Could it be the batteries in the CS92 for the hot water probe?

Log out of the app. Delete, reinstall and log in again and see what you get?

See page 5 & 6 of manual here: https://www.plumbworld.co.uk/documents/ ... -guide.pdf

You need 1 BRD91s - one for hot water and the other for heating. The box on the left is a CS92 which is the sensor for the temperature probe from the hot water tank.
