    Replaced Actuator not working properly

    I have taken up a lot of time trying to sort this problem with great advise from members. Still unable to sort and in desperation, I called in a local heating engineer. He came recommended and seemed very professional but has now spent six hours trying to figure out the wiring of my system! He...

    Replaced Actuator not working properly

    There is a junction box in the hot water cupboard, that goes to the connecting block then to the actuator. The controller is situated down stairs. I will photograph all and post. I really do appreciate your time taken so far. I have to go out now & it is going to be dark soon, so will start...

    Replaced Actuator not working properly

    CH was switched on when I checked yellow To confirm, there was no power to the white terminal during any of the 4 combinations. My programmer is a Potterton EP 2002 The actuator is wired to a connecting block ( as in my diagram) which in turn goes to a junction box. Which do you need to...

    Replaced Actuator not working properly

    Should I have turned off power to reset actuator before doing your latest test? Actuator is still over to CH! Now check the white terminal. Does it have 240V when the HW stat is turned down or HW is OFF and 0V when HW is ON and HW stat turned up? If so that is the correct terminal for the grey...

    Disconnected white & grey, CH stat turned up, Cream was now live & I have connected white to this terminal. Now have orange & grey wires not connected. Boiler not responding. Actuator moved to H position.

    Points 7 to 9 completed. The actuator arm has moved right across and the indicator shows H, but the boiler has not lit.

    Repeated steps with orange wire disconected, boiler lights fine, water heating up. Does this tell us anything else than HW stat is ok? Where do I go from here? If there is a wiring error, is there a way I can check it with just a neon tester?

    Going through your list of instructions, your 10th. point is ' Boiler should light......' Boiler does nothing prior to this because power is off before your point 8, 'Turn the power on' & point 9 Turn HW on at the programmer'. I can't tell where the cream/white wire goes to. The only double...

    Replaced Actuator not working properly

    Good Morning D_ Hailsham I have followed your instuctions through to point 10 & the boiler is not responding. If this suggests a wiring problem, I was very careful to copy from previous actuator wire up, trusting it would be the same. If it helps, I have done a diagram of the wiring...
