Hive to a combi boiler with 2 zones?

I have never worked out why one should need two Hive thermostats? From what I read the Hive thermostat has a "Demand for Heat" system, so the Hive head can switch on the wall thermostat, but the standard motorised valve it seems does not take the Hive head, it seems to be designed to have a motorised valve on each radiator rather than one valve for a group of radiators.

With all the houses I have lived in, upstairs is always warmer than down stairs, and the upstairs radiators always seem to be over sized. So if you control down stairs with a wall thermostat, you can have programmable TRV heads up-stairs as boiler run time is enough without any "Demand for Heat" being required.

I decided to use individual control for each room, with the wall thermostat in the hall, so only the hall controlled 24/7, all other rooms as required, but it has not really worked. What is missing is a big stick which raps my wife on knuckles every time she leaves a door open.

The main living room has raising butt hinges, she has a gnome she uses to hold the door open, but not all the time, so we have a learning thermostat (Nest Gen 3) that can never learn as there is no constant set up, with doors being left open or closed. Nine programmable TRV heads, 4 being wifi and 5 bluetooth, but all to no avail as doors left open.

cau'r drws she understands, but not willing to do it. So all this work and money to set up smart controls to no avail, is it just a Palmer thing? I am from the Palmer's who started the shipyard, maybe I need to stamp my feet until they go through the floor like Sir Charles Mark Palmer?

 

Hi Steve, im pretty sure i have exactly the same set up as you, looks identical, even down to the carpet haha do you have a diagram of what you ended up doing with the wiring?

 

Brill Thank you Steve, this is what I have. Like I say looks the same as yours so should be straight forward?
Only thing that looks different is my wiring in the boiler? My boiler is Ideal Logic ESP1 35

 

Step 1 is give your hives a LNE.

 

Link live - terminal 1 on both hives.

remove the black and brown wires as these belong to the old stat.

 

Then terminal 3 on both your hives go to the terminals that you removed those black wires from. 1 black wire to each brown wire.

 

That’s great thank you!

should I wire a fused connection unit between each receiver and the centre?

 

Power to the wiring centre and the rest of your controls should be from a single fused connection unit. Trace the live feed back from the wiring centre.

 

No. Easiest way is just to run a 5 core cable for each receiver from the wiring centre.

 

Okay brill, thank you.

Wired my receivers up

 

This is how I’ve wired the centre

 

Hi Mike i could be doing with your help regarding this aswell. Is there any way of messaging you

 

Looks correct.

 

Start a new post.
Include as much details as possible.
What you have fitted currently.
What you plan to fit.
What boiler you have.
Pictures of existing wiring.
The more details you initially include the less questions will need to be asked.
