Honeywell cm61 to hive

[Acker82]

Hello, I’m looking to install my hive on place of a Honeywell cm61 the cabling looks different to my old stat no neutral.
At my old place I just linked from L to no 1 with a N and pin 3 as the switch … any ideas ?

Do you have a combi boiler or conventional/system boiler with motorised valves?

Hi, thanks for your reply. it’s a combi Glowworm 30cxi

Looking at the wiring it’s likely going back to the fused connection unit, which is better for you so you don’t need to remove the boiler casing (would need checking for safety afterwards). If you can find out if the blue is connected to the neutral, and if not, it could be done. This would give you a permanent live and permanent neutral, then linking the L to com and then use the switch live to the boiler, which is your yellow.

Ok, yes that makes sense. I will check it out before starting it.
Many Thanks for your input much appreciated.

That is just a battery operated switch.
Live in live out. Or volt free in and volt free out.
