DANAFOSS Radiator valve head removal

[MG2004]

Hello,

please could someone tell me how to remove the control knob, the plastic cap only that regulates the temperature. The system ws fitted 9 years ago and one radiator has not been used for a while and it was turned to the lowest position. I think the adjustment pin is stuck and will not let the rad heat up. There is a small pop up clip - done that but still can't lever off the control knob.

Thank you.

Hi

Done it - Lifted the small switch with a screwdriver - held the top and twisted clock wise and pulled off.

Re-fit - hold top and twist the bottom part and it clicks - line up groves, push down - it auto locks and push down the little clip.
