Hi, does anybody know how to wire a combie, using the combie heating side to
do the heating and a tank of hot water, and the instant (mains water) side
to do just the kitchen tap.
It is a Potterton Performa 28 and using a Siemens heating pack (3 port,
timing clock RWB9, room stat & cylinder stat)
Have got the heating side up and running and doing the water tank, but not
done the mains tap.
Have got the L,N,E coming from the wiring block going to the boiler but they
are only live when the timer tells it to be. I assume there has to be
constant live for the hot tap to be able to fire up at any time.
Any help appreciated
