3 way valve

Post  Alex on Sat Feb 12, 2011 3:38 am

I have a new SAC board to fit to my Boilermate 111, the old one which burnt out is wired for the 3 way valve on terminals 12-15, I see in the boilermate instructions the valve is wired to terminals 11-14, does anyone know which is correct ?

How many wire / cores on your 3 way valve?
Also has your boiler pump over run?

Thanks again for your help, I think I'll take your advice & give them a call on Monday. Looked on the Danfoss site & the HSA3 valve wiring is
blue [N] white/brown [HTG call] orange [HWS call] Grey [HWS sat], so no earth connection.

Cheers Alex.

Thanks for your help Mike, my original wiring is correct for the Danfoss HSA3, the orange lead is [HWS call ] & is put in terminal 15 which is unused.
Alex.
