Drayton motorised valves now feature removable actuators which simplify installation and future servicing.

No tools are required to fit the actuator to the body as it simply clicks into place.

To remove just press the release button and lift the actuator from the body.

Hi
My system has this type of valve (part no ACL Lifestyle 679H340 30L0). Upon investigation as to what was intermittently tripping my electrics I found that water was leaking into the motorised part of the valve and also dripping underneath.
Please are you able to advise whether this is likely to be fixable or will I need to replace the whole unit.
Thanks in advance.

Hi
You will need to replace the whole unit. Please note it should be mounted so that any leaks drip away from the electrical actuator.

Just fiited new grundfos pump and a new mid position valve MA!/963 all plumbed in no leaks system vented.Connected the new cable to the old cable via REGIN 5 way connector on the mid position valve.My voltage pen is giving false positive with electric switched off on both pump cable and valve cable.The cables all match up within the REGIN105 AND THE WIRING ON PUMP SEEMS OK ANY IDEAS PLEASE ? Answers1

I'm not sure what you mean by power off, as the voltage must be coming from somewhere. If you mean no demand, then if the last demand was heating only, then the valve may output a lower voltage (50-150v) on the orange wire until there is another demand. This is perfectly normal operation of the valve. The pump or boiler should not be activated by this lower voltage.

Good Afternoon,Im replacing an old 679H340L0 with the new MA1.Dont have a problem draining down system and replacing valve body.With the electrics would it be ok to leave old cable connected to junction box and just join up new/old cables with inline connectors and choc box ? Answers1

Hi. Yes, but a choc box would be too small, I would recommend HCO code 11C13 instead.

If the mid position valve is letting hot water through the the heating when only calling for hot water is this something that can be repaired? Answers1

No, it will need to be replaced.

I have tried to move the Drayton Automatic control to midway from H position but cannot move it. Any idea why or how do I move it Answers1

If it stays in the H position when you switch the power off then it will be stuck and need replacing.

Hi,
I currently have a Danfoss HSA3 fitted that has failed (heating only, no hot water).
Can I replace it with this instead? This seems better as it has a manual override which the Danfoss doesn't (I mean I can't select hot water only), and this seems like a bit of an upgrade.
Thanks. Answers1

Hi,
You will need to replace the valve body to fit the Drayton. However, if it is stuck on heating only it may be because the valve body is stuck so needs replacing anyway. Neither unit allows you to override into hot water only, as they have a spring to return them to this position.

Make sure your existing valve is 22mm before ordering this one.

I have an ACL Lifestyle Mid-Position Valve 22mm 679H34030L0 which I need to replace. Please could you let me know which is the replacement valve for this. Thanks Answers1

This is the correct one.

I need to replace the actuator and plug it into a Simp-L-Fit box. Can you supply this actuator wired to relevant plug? Answers1

I'm afraid not. I would recommending using HCO Code 11C13 to connect the old plug to the new actuator.

I’ve read all the questions and answers and I have the same problem in that I have the all non removal head version. The only part that is broken, is the plastic arm under all the motorised parts. I have the entire actuator stripped and I could put it all back together if I could just take the plastic part from the MA1 and put it into the acl. don’t suppose that’ just the plastic parts are the same in both? Answers1

I have heard of it being done, but due to product development, I cant guarantee Drayton has not changed them. The fixed head ones are so old, that it really is best to just change the whole valve.

I have a faulty 679h340-3olo actuator, I know the MA1 is incompatible but could it be adapted to fit the 679h340-3olo valve body? I'm trying to avoid the expense of an engineer visit to drain down the system to fit a complete new unit. Answers1

I'm afraid not. If it is only the motor that has failed, you can change just that.

When CH & Hot water programmed to come on together it only heats up the radiators and not hot water! The only way to heat the hot water is to have the controller switch the water on separately? Is this a valve problem and if so can I change the valve without draining the system? Answers1

Assuming it previously worked (not a wiring problem), then it does sound like the actuator will need replacing. A drain is not required to change the actuator.

Does this come with wiring? Answers1

Yes it come with a 1m cable.

Hi. The boiler works on the hot water setting but will not turn the central heating on. Room thermostat is working but the Drayton Mid Position Valve does not move to heating. I can move it manually to the mid position and I get hot water and central heating. Will the MA1/679-3 replace the 679H340-30L0 and can this be done with out touching the pipe Work? Just changing the top electric bit? How is it removed? Thank you. Regards David Answers1

It will replace it, but you will need to drain down and replace the whole valve. However, it sounds like it could just be the Synchron motor inside. You can change that without draining down. HCO code 02E02.

My very old (perhaps 16 years) Drayton mid position actuator has the code MA1 written on it rather than MA1/679-3. Should I order the MA1/679-3? I actually intend just replacing the electrical top bit without touching the pipework. Answers1

If the pipework is 22mm, then it will be the MA1/679-3 The MA1 actuator is available on its own. HCO code 23D03

further to last question - when CH only is activated via the controller ( with room thermostat turned up) nothing happens. When HW is activated the boiler comes on and the valve stays on HW only . When both are activated it is the same as just HW being activated. Answers1

For CH only, both the white and grey wires should be 230v. For CH and HW, white only should be 230v. If that is what the valve is receiving, then it sounds like the valve has failed.
