Hi All,

I am replacing my Myson MRT1 thermostate for a digital Honeywell DT200, Ihave a question regarding the wiring, and looking for some help please.

The current stat is wrired as followed:
1 = Brown (Permanent Live)
3 = Black (with brown sleeve) Switch Live
4 = Grey (with Blue sleeve) Neutral.

The new stat has connectections maked

A
B
C
does anyone know which goes to which, i have the wiring examples and i think this is correct?

A = Brown
B = grey
C= Black
??? :shock:
 
In other words - that is brown to A, black with brown sleeve to B, grey with blue sleeve into a spare piece of terminal block and tucked safely away inside the enclosure as it is not needed. Terminal C has no wire connecting to it.
