Drayton digistat not switching boiler on

[billyb24]

If you can post a pic of the upstairs zone valve you might just be able to swap the actuator

Here they are

Yes they have removable heads so you can just swap the actuator over no plumbing work involved, you get a connection adapter to make it easier if you want to do it yourself

Is there a specific part number I buy from say screwfix?

Go to city plumbing (merchant) or plumbase if you have one? Screwfix look like they don’t sell the Regin connector, but they do sell the actuator - Drayton ZA5

Hi guys I'm back. I bought a DA5.

Before attempting to fit I've tried something.

I switched the DA5 over and both activated, switched them back and both activate.

When I manually up the temp on the upstairs thermostat the switch on the side of the DA5 with flick upwards from A to B and the lever on top movers to the left but the boiler does not engage.

I have turned the valves, both seem ok as boiler will fire when I turn them manually.

So I'm not sure if it is the DA5 fault at fault.

Could it be a fault on the boiler circuit board or the Drayton +3 controller?

Sorry for all the questions.

It is absolutely nothing to do with the boiler, get that out of your head , it is a faulty end switch on the upstairs zone valve, or a bad connection at the wiring centre from either the grey or the orange wire

Hi Ian.

I switched the whole unit out. The heating is now working.
Thanks for your help and patience with me.

No problem, glad you have got it working, they can be a bit temperamental and dont always fail, sounds like your old one had a weak motor that wasnt fully opening

All working well, now to post another question in the building section. Thanks again.
