Hi guys, I'm new to posting on the forum although have found many threads very useful
I'm in the process of installing my first Daikin Altherma (LT) system. I mainly install vrv's and splits so my knowledge on plumbing and chilled water is limited.
The problem I've got is with the wiring on a Honeywell V4043h 2 port motorised valve, which has been put in by the plumber to isolate the underfloor heating whilst in cooling mode.
I understand the port is normally closed. I've got three terminals on the hydrobox to wire the 2 port valve into they are labelled:
5. Normally closed valve
6. Normally open valve
7. Common
However coming from the valve I have a 5 core cable including colours, brown, blue, earth, orange and grey.
As I only have three terminals I wonder if anyone can tell me which coloured cable I need to wire into which terminal?
Any help would be sincerely appreciated
Many thanks
Joe
