Hi there,
I am having problems with my heating and hot water. They work independently using the programmer but not both together. Have read lots of posts here about this particular programmer but not found a solution. I have isolated the programmer from everything else and then tested the voltage outputs and get what I think are unusual results as follows;
Heating only
Brown 67v
Black 240v
Grey 240v
Hot Water only
Brown 240v
Black 67v
Grey 35v
Both together
Brown 240v
Black 67v
Grey 35v
I think that the 240v signals are all as expected and that the other readings ie 67v or 35v indicate a fault with the programmer. Would be good to know before I simply replace.
many thanks.
