Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries
Carry out a full reset, switch power off at fused spur leave off for five minutes and then switch back on, this will cause a reset procedure to take place. Then come back to me with the results ~ Ian
Thank you Ian. By "Fused spur" I presume you mean the switch in the white box next to the controls. I have done this. The boiler shuts down, but not the control panel. When power switched on again, the controls just stay the same!
OK you have a faulty controller then, you will need to replace it, the Drayton Tempus is still available but I would have to check it the series 7 is a direct replacement for the 3 ie, unplug one and plug in the new one ~ Ian
OK the Tempus 7 mark 2 is a direct replacement for the 3
