drayton mid point

[poshman]

hi helpers, I have a fairly new drayton mid point actuator code MA1
occasionaly it dont click over to heating it will either stay in mid or water position. to get it to move I use programmer to put the hot water on then turn that off then put the heating on then it moves or I can gently move the switch over to H on the actuator so would a club hammer fix it

another strange thing is I have a salus RT300RF receiver wired into Drayton dual channel programmer. the green light on the receiver never seems to go out ? it says in the book " the LED ( green ) illuminates when the receiver unit is receiving a heat call transmission"....

if I lower the temp a few degrees on the thermostat the green light does go out but otherwise the green light stays on even when the heating is off for the night so over to you guys Thanks P M

Remove the actuator and check that the valve spindle can be turned easily by hand. It will only move less than a quarter turn between stops. If it is at all stiff, lubricate the spindle with a small amount of silicon lubricant - NOT WD40 which will rot the 'O' ring seals.

Obviously a wiring error, but where?

Can you post pics showing the wiring of the Drayton programmer, Salus receiver and the wiring centre (junction box)?

Thanks for that Mr H, I was only joking about the club hammer but I give the body of the valve a tap and it must have loosened something inside, hopefully done the trick

As for the green light staying on, will try and post pics but at present it isnt causing anything malfuntioning cheers P M

It would still be a good idea to remove the actuator (that's the metal box) and check the spindle is free.

But it shouldn't stay on all the time, so there is something wrong with the wiring.
