Hi All,
I am trying to fit a honeywell DT90E Room Thermostat.
I have removed my old thermostat which is a Sunvic TLX 2356
The wires I have are:
Brown - Live I guess
Blue - Neutral I guess
Earth
Now the DT90E has three ports, A, B, and C
Which wires do I put into A, B and C?
I have a gravity system bolier - Glow Worm Ultimate its quite old
Thanks in advance for any help.
Regards
Squiral
