After the hike in oil prices (34p to 53p/ltr in 9months) I have just added a CM_Zone starter pack to my CH system to chop off unused rads.
I checked everything out before fitting and had no problems binding the rads (HR80) to master controller (CM67z) or to the boiler controller(HC60NG) etc. During the install I check the field strengths etc and that each rad commanded the boiler on/off as required. Fitting the boiler controller was simply a case of paralleling my existing Drayton room stat that looks after the rest of the 'dumb' rads.
But I have a problem. For some reason I find an odd rad ON when not requested. The set temp is 20deg which is not one I have programmed on the master controller (I deliberately set 16 & 21deg on all cycles/days just to check this). This has happened three times now on three different rads. The only common factor so far seems to be that it happens when the HR80 is close to the CM67z (10' or so).
Has anyone else experienced this behavior?
