Hi
Recently fitted a Vokera Unica Max 35 combi boiler.
Purchased Hive hub/ thermostat. Need some advice/ info on connecting the receiver to the boiler. Wiring instructions please.
Hi Ian
you say not to connect L and 1 but all other videos say to connect L to 1 ( common) loop to supply switching power... Not questioning your wisdom /knowledge just trying to understand - dont want to damage my new boiler... possibly now thinking of getting somebody in- do you do this kind of service, we are based in Airdrie not far from you!
But all other videos say to connect L to 1 ( common) loop to supply switching power... Not questioning your wisdom /knowledge just trying to understand
Most boilers do use 230V to control them so the link to L is required to provide the 230V mains supply. However, your boiler doesn't. The installation manual specifies "Contact Must be Free of Voltage" If you make the link, the contact will not be "Free of Voltage" it will have 230V applied which will probably blow up the boilers internal circuit board. Don't forget......
There can be several variants of boilers and they can change during their manufacture. The diagram I posted I got on line from the Vokera website. Click here to see it on page 32. If yours is different post back the details.
