Max CV water setpoint

Postby JoHe » Mon May 03, 2021 5:22 pm

Hi,
I need some help on my OpenTherm settings.
I have running Domoticz on a RaspberryPi 4
Attached an OpenTherm gateway (by LAN) and configured in Domoticz.
It returns 26 devices.
one of them is Max CV water setpoint and this is the one I want to control ie change when needed.
My project is to set the temperature higher when heating is wanted in my bathroom.
Standard it's set to 45 degrees due to the fact that my whole home is equipped with floor heating
except the bathroom. I have a temperature sensor in the bathroom so I know when to start heating.
At that point I close all valves to the floor heating and open the valve to the bathroom.
In order to get a nice temperature in the bathroom I need to increase the water temperature to a
minimum of 60 degrees. However I can't change that value. I can change it on the CV itself, so
it is possible.
I've made a screenshot of my devices however can't find any option to upload it, therefore
below in text format.
need some help on getting this solved.
