Hi I am trying to wire in a new digital central heating controller Im stumped
In my current setup Swithmaster 905 -I currently have connections going to the following
B – Yellow/Green Cables x3
N – Black / Blue / Blue
L – RED x1
CH ON – RED x1
HW ON – BROWN x1
I then have a black cable belonging to CH ON cable not being used and a spare brown cable (Don’t know where from) not being uses – Wired into C (Spare Terminals)
I have no CH OFF or HW OFF Wires - Its connected to a Rayburn it it helps
Currently the central heating and water is on all the time and controlled by the temprature dial
Im trying to wire it into a Honeywell ST9400C – can anyone help?
