I have a Trianco Tristar Optima SB - which works perfectly btw, This is attached to an ACV "Smart line" unvented Hot Water Cylinder.
The heating and hot water both work really well.
My problem is the controls end of things.
I have a Sunvic 3 port valve which needs to be connected to the cylinder and boiler. This is where the problem arises.
The boiler has a connection point for a three port valve which comprises three wires on the wiring diagram these are labelled Heating, Neutral & Hot Water.
The Sunvic Valve has Four Wires - Blue (Neutral?) Grey Orange & White.
I have looked through the wiring diagrams from both the Cylinder and the Boiler, the cylinder I am happy with - this deals with four wires,
but the Boiler.....I keep coming up with one wire left over
Can anyone assist? Please...
