Installing Hive Multizone to Ideal Logic 35 with 2x ESRTP4 thermostats

[MickMcKenna]

Hi All

Apologies if this is in the wrong area just looking for some quick advice.

I want to replace our multizone thermostats (2x ESRTP4 ESi) http://www.esicontrols.co.uk/esrtp4.html
with two Hive systems which will connect to our Ideal Logic 35 combi boiler.

Ive had a look through the manuals but wanted to double check the wiring. The ESi currently have two cables each, one to COM and one to ON as shown in the two first pictures.

The documents for the Hive wiring show a lot more connections including a permanant live which I dont have but from some previous reading people have said to connect COM to 1 on the hive image below and ON to 3 and I should be good.

Does that look right to everyone before I purchase these or will I need a live as well?

Thanks for any help!!

Yes Hive does need a permanent Live to the receiver.

If you're just looking for two zone control you'd be better off with a Honeywell T6R-HW and a second thermostat unit. It can then be connected using the much more efficient OpenTherm wiring.

Be aware that any work on an Ideal Logic which requires removal of the front case (so essentially all work on the boiler) should only be carried out by a Gas Safe Registered Engineer due to the design of the boiler casing

Thanks for the reply

I have no intention of removing the boilers cover so dknt worry, I know my limits.

Thanks for the advice on the other model ill have a look at that.

I did find another post with a similar layout and circuit diagram to follow that i was going to check. There is a third cable at each wired thermostat that is blanked/terminated off which im guessing is the neutral so I should be able to do somethjng similar to the below diagram from the other thread using the three cables available but ill need to check the current wiring again.
