Hello - a short while ago our thermostat stopped triggering the hot water, it shows orange on the dial but does not trigger the boiler anymore. The boost function does the same, shows as triggering on the dial but no hot water.
The button on the link works and heats hot water.
Our plumber says it's an issue with the thermostat but I don't seem to be able to get any answers. I'm seriously thinking of going back to a traditional thermostat, our last one lasted nearly 20 years with no issues.
Does anyone have a solution?
Many thanks for your time.
