It is a thermostat, you are showing here. The thermostat can be defect, when it does not switch on the correct temperature. But when the 3 wires I see are the only ones, connected to the system, I wonder it could work at all.
Is this in the Netherlands?

How do i wire a potterton programable controller


Hi,

All you need to do is look at the wiring diagram on the back of the old room stat, you will have the following:

(normally wired with these colours)

OLD COLOUR CODING

Live (sometimes called common) - Red
Neutral - Blue
Switch Live - Yellow

NEW COLOUR CODING

Live - Brown
Neutral - Grey
Switch Live - Black

All you need to do is wire up the new stat with this in mind. (please note: if the wires are not colour coded like this then do not proceed and get an electrician)

Any problems or questions let me know

I hope this helps

You could possibly have an ignition problem. The controller will go into a lock-out condition if flame is not established. Turning the temperature control down and then back up may be serving to reset the control system so it tries again.
