wireless stat

[scrimbotoo]

Hi all
Im trying to connect a wireless Drayton +3rf stat ( volt free )to a boiler ive never delt with before, the boiler is a Ariston micro genos 23mffi with a mechanical clock timer with 3 wires going to spade end connectors , a red wire to 1
grey wire to 5
black wire to 2 linked to 3
Is anyone familiar with this boiler and can help identify a common or a call for heat , i know its a bit sketchy im just trying to help a plumber out ( wagos and wires everywhere ). Ive dealt with the stat many times on other boilers but never with this one, have to say it looks a pretty cheap boiler .

The black link will need to be removed and ur flex from the new controller will get connected to these. I'd imagine red n grey would be live and neutral..... But that's just a educated guess.

what connections do u have on the new rf unit?

live
neutral
com
normally open?
