  • Anyone know if you can change the actuator head only on one of these? The manual override lever works but the spring return isn’t switching the valve when the heating goes off.

  • I did a while back, rather than paying a fortune for a Honeywell valve. IIRC I had to buy / return a few motors until I got one that worked.

    Might be worth replacing the whole head unit, rather than fannying about with swapping the motor.

    (£15 vs £25 for the motor vs unit for Honeywell)
