red compact 35 biomass wiring any help

[diverdee]

hi
been asked to wire a red compact 35 biomass to existing s plan and instalation guide rubbish (been translated from italian).anybody wired one before think i got it just wanted to ask a couple of questions if poss ie assume terminal 1 and 2 are volt free and are for the room stat through zone valve and same for cylinder stat.when you enable room stat mode does this disable the internal clock on boiler so can use external.

there are no agents or reps or tech support in england for these boilers god help the customers

Mcz are horrendous boilers. It will disable the on board clock but these boilers should never be used on s plans they don't work properly unless used with a buffer so be wary.

It's fine to use them on an S-plan provided you design the bypass correctly..
