Help Hive Installation from this configuration

[Vynter]

Hello, I’m looking for any help to connect hive to the boiler. I have done it before but in a different setup. Look at the attached pictures, thanks.
Look at the switches on the left. I don’t know what they do exactly.. I think are connected to electro valves. When off the house get warm only downstairs. I’ll try to get a better picture of the switch’s connections. Thanks

That’s a time switch, often used with an immersion heater. Is that definitely for your heating? Do you also have a room thermostat if it is?

Hi CBW, yes we moved in a new house and I would like to install Hive. Yes I would like to replace the apt timer switch with the Hive. But I’m not sure of the wiring, if I need a bridge between common and heater on(see hive wiring setting). No there isn’t a visible thermostat around the house. When the switch is on the boiler it’s always active until stop by itself. Also when I switch off manually I can hear the electro valves buzzing. I’m waiting more information from the previous house owner. I’ll update as soon… thanks

If you want to use a Hive with that and going on the information given, get a Hive single channel, then wiring: L to L, N to N, live out to terminal 3 and link L to com (1)

Hello I’ve been out of this project untill now.. so this following is an update of it.
I draw a picture of the wiring, as per your instructions…and I’ve checked the valve too, please check the picture attached.
Looks like there’s no way to command the hot water for the sink/bath on his own. Both valve they work only for the radiators. And now yes I’ve understood what those two switches are there for..
I’m happy to go with the wiring.. like in the scheme/draw.
Just one question.. why I need to link L to Com1
What is the Function of Com 1 ?
Thanks.

Now you have provided additional information, you could possibly get a 2 channel hive and wire into the wiring center and use the hot water side for the additional heating zone, or get 2 Hive single channels. The com 1 is to provide 1 part of the switching, terminal 3 provides the other.
