Potterton EP1001 Programmer Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

[Mike Reid]

The digital display on my EP 2001 Programmer has gone funny and not in a ha ha way! The display appears partially and none of the function buttons work with neither the CH or the HW light coming on.
Any help to solve the problem will be greatfully appreciated.

Corrosion is a common fault.

This may be caused by a damp or wet environment or it might have a leaking internal battery.

Have you tried powering down and back up again. Sometimes the electrics get screwed up and need a re-set.
