Hi Guys,

just wanted to get some advice on the wiring of the new MC6 thermostat?

I have attached a picture of what I am replacing and the wiring diagram of the new Thermostat. Please also see recorded voltage readings I have taken.

Current Honeywell Stat :=
1= 230v always (Red)
4= 230v
3= 0 (Yellow)
2= 0 (Blue)

When thermostat switched on
4=0
3=230v (Yellow)
2=0 (Blue)

So based on this the new wiring diagram would be?

Red = L ( Live)
Blue = N (Neutral)
Yellow = No ( Switched Live)

Please note I am not using it to control Hot water.

Do I need to jumper between L (Live) and COM?

Thanks for any advice and if you need any more information?

Thanks.
