Wiring Hiv to Vokera Unica 28e

[Moataz Farrag]

Hi everyone,

I want to wire Hiv to a Vokera Unica 28e, the wiring on the boiler seems straight forward as far as L&N & Earth are concerned but I'm wondering which ones from Hiv goes into which on the thermostat side.

Basically out of Hiv goes L & N + "Common" and "Heating on" as per the manual, so L to L and N to N but which one goes to the black wire on the boiler and which to the red, hope that makes sense, pictures below.

Many thanks

doesnt matter it is simply a switch will work either way round, the hive doesnt need an earth
