Hi All -
Some advice please on replacing Thermostat and Wiring.
System - Megaflo Water and Heating - Installed 2007.
Original Thermostat - Dial type - Honeywell T6360B
Wire Connections 3
BROWN Terminal 1
BLUE Terminal 2
BLACK Terminal 3
Above Thermostat replaced with Honeywell CM900 (Digital display) Installed 2013 and works fine.
After seeking advice - wired as follows
BROWN Terminal A
BLACK Terminal B
BLUE unconnected
I now wish to replace the CM900 with a Fixed/Wireless Honeywell Y9420H Sundial RF2 Pack
The connection options are as follows.
N
L
1 HW OFF
2 CH OFF
3 HW ON
4 CH ON
The Thermostat is only required for Heating temperature - nothing else.
So the Question is - please -
Of my combination of Blue Black Brown wires - to which terminal should they be connected on the new Sundial
Regards
Martin
