Replace centaurplus c21 with Hive

[Carlik]

Hi everyone

I’m attempting to switch a centaurplus 21 with a hive active programmer.

unfortunately, there was no wiring diagram and the wiring just looks a bit unusual to me.

I’ve attached a photo and any advice on how to change this so that I can use hive would be greatly appreciated!!

Is that red wire going from Live to terminal 4? Also is there a wire in terminal 3?

Live and 4 are two different wires.

apart from L, N and the two in 4 there’s no wires in the other terminals.

Google is your friend Installation instructions for centaurplus 21

Looking at your picture it seems the unit has been bypassed. So likely you will need to do some testing.
