Folks,

Danfoss FP975 heating clock is acting very strange.
It will not turn on the waterand central when activated manually. The red light comes on for a few seconds
and then it turns off and shows error code of N33 whatever that means on screen.

If i decide to programme it in via the clock, it comes on at the correct time but this time it continually tries
to activate the cycle by turning on the light the turning itself off throwing the code and trying again and repeating this process continually.

Bt then even stranger if i approach the clock an hour later it works fine !!

What could be wrong here and what is code N33 ?


I think this clock is a load of CRAP - as when the power goes off the flippin programmes are all lost too !!

Any help most appreciated before i attack it with a sledge LOL.
 
get a new programmer there are many good ones out there, honeywell are the best but also expensive. drayton and danfoss also good. screw fix have a good selection.
