Resolved Question:

there. We have a Drayton Dual Channel programmer which hasn't been operating properly while (just the heating). reason it comes on in the morning, but not of the evening programmes we have set. The clock and date is right, the thermostat is set to the same level so not sure why it works first set and not the others!
thank you
