Hi,
I have a Boulter Camray 5 (95/130) System Boiler which will be connected to 3 x 2 port valves ( central heating rads / under floor heating circuit / hot water cylinder).
With external programmer and thermostats etc.
The OSMA UH1 control centre I'm using requires boiler enable connections (volt free) SL & L1 (grey SL and orange L1).
However the boiler only seems to have a L, N , E connection lead.
Can anybody tell me where these connections are and how to wire it up.
Just noticed that the manual say's: -
If optional internal programmer is not fitted use terminal three for the switched live from the external control circuit.
Any help or advice would be appreciatted
Thank you
