Hi
Thanks to these forums I have been able to 'solve' my lack of heating mystery however I still have a 1 query.
My house has been fitted with 3 of the above zone actuators along with the Drayton wireless thermostats. My house has 3 areas of heating - the bathroom rads the downstairs zone and the upstairs zone. The bathroom rads are always on except for my bathroom which has never worked despite changing a 'stuck' TRV. Anyway I can live with that - just. My problem was that the upstairs heating never really worked properly after the first year of fitting. Come the winter of the second year I found that I had to operate the digital receiver manually to have heating and this year (year 3 of fitting) nothing worked. The thermostat was requesting heat and the receiver was getting the message and both seemed to be working fine but the radiators were cold. Finally found the culprit was the actuator which was permanently on the A mode whilst the others were on B and working fine. pressed the black button on the top and it slowly went to B and voila! warm radiators!
My question now is - and from these forums I understand that the black switch should move freely - indeed click from A to B and back. This one seemed to be sluggish as if coated in grease and dust - I understand that I can lubricate it - would this be with a simple spray of WD40 or is it more complicated and intricated than that?
