Logic Combi ESP1 35 + Hive Active

[Zeixn9]

I’ve done some research as I’m looking to replace my current thermostat with the Hive Active setup.

As the Hive is wireless I’ll be fitting the receiver in place of my old thermostat which is connected to the boiler using 2 wires, and 2 that are spare likely because my current thermostat is battery powered?

Based on my understand am I right in thinking this is how it would wire into the Hive? I’m stumped as it seems I’m missing a wire to connect to the permanent live part?

Green yellow = Earth tether
Grey = permanent neutral
Brown = Common
Black = Heating on (NO)

Can anyone shed some light on if it’s a simple install and which wires need to go where please?

The battery will be a back up, the 2 wires connected are the switch wires.

Which hive have you bought ? There is a wired version now as well as a wireless.

Where is the room stat going to be located?

The new hive receiver needs to be wired into the boiler terminal strip which means removing the case which then means carrying out a performance test to make sure it's operating safely.

I would recommend paying for installation otherwise if anything goes wrong it's on you ..

Hi,

As above, to complete the wiring connections to that model of boiler, the front panel needs to be removed and that would compromise the room sealing of the appliance - this must only be done by an RGI.
EDIT: sorry, unless the other end of the cable goes into a junction box, or similar, before entering the boiler!

The existing thermostat could have the permanent live connected to the common terminal.

If you still want a smart thermostat, but don't want the hassle of calling out an RGI - the battery powered heat link with the Nest thermostat E, may be an alternative?

However, you may want to do some further research into the benefits of using OpenTherm - your boiler is capable of supporting it, but the Hive system isn't.
Again, installing an OpenTherm thermostat would need an RGI to make the connection to the boiler and carry out safety tests afterwards.

I hope that makes sense. Good luck!

You are mistaken the green,yeoow wire and the grey wire are not used, they are simply just sitting there
Green yellow = Earth tether

Your boiler is OpenTherm compatible so it's rather a shame to be fitting a crappy on/off Hive to it when you could be getting better efficiency out of it with something like Honeywell T6 or Nest connected via OpenTherm
