Hi all,
I'm replacing an old Satchwell (or Sunvic) TLX 2356 mechanical room stat as it only "clicks" on above 25C.
New stat is a battery powered digital Honeywell DT90e.
TLX wiring as follows (as I understand it):
Terminal 1: Demand (or "Switched Live") - Yellow
Terminal 2: Satisfied - Brown
Terminal 3: Common - Red
Terminal 4: Neutral - Blue
Am I right to wire the new Honeywell stat as follows:
Terminal A: Common - Red
Terminal B: Demand - Yellow
Terminal C: Satisfied - Brown
Isolate and insulate Neutral - Blue
HW & CH both heated by a (very) old Vulcan Continental floor-standing boiler, circulator pump, 3-port valves, etc...on a gravity fed system.
Thanks,
Spencer
