Hi all,

My boiler requires me to complete a yearly maintenance and in order to do this all valves need to be opened and the boiler off. I can then set the pressure etc. Does anyone know how I am able achieve this?

Thanks

Set all valves for 30°C and remove relay from boiler.

I have the same problem, but the current temperature is 35 degrees and the valves do not open.
What can I do?
