Q: Hi, I have read that this is a direct replacement for Lifestyle 679H340-30L0. 1. Can I easily remove the old one (e.g. will system need draining, how many screws etc.); 2. Does the MA1 simply 'click' back in the place of the old one? Regards and thanks.

A: You will need to drain the system, and then remove the 3 nuts connecting the pipes to the valve. The new valve will fit directly in place, the existing nuts will screw onto it. Be careful that a A/B sides matches the direction of your previous valve. The new head will then click onto the new valve. The wiring of the new head is exactly the same as the old one.
Q: I want to replace a acl Lifetyle Mid-position valve 22mm Ref 679H340 30L0 that has a aux micro switch. Does this have the switch as well

A: Yes it does.
Q: Re my last question, do I need a plumber and electrician or just an electrician?

A: Most plumbers will be happy to do the electrics as well. Look for someone who describes themselves as a "Heating Engineer"
Q: I have a lifestyle mid position valve with the number 679H 340 3OLO on it. Will this fit and is it easy to swap?, thanks

A: Yes it is the replacement. The thread and gap in pipework is the same. The wiring is also the same. So it's a fairly simple swap.
Q: Does the Drayton MA1/679 3 mid position valve have similar wiring to the Honeywell V4073A1039, 3 way midposition valve?

A: Yes it is the same.

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.
