Do I just copy wires Hive

[Tarquin1985]

Hi all,

Before I go ahead and cause catostophic damage, I'd just like some confirmation that I'm about to carry our the correct procedure.

I'm connecting a Hive 2 receiver. Here's a picture of the old wiring:

Unfortuntly, the Hive unit doesn't quite fit to this bracket for some reason.

Do I just put the wires in the same place on the Hive bracket which looks exactly the same?

Thanks

This is a universal backplate, but not all programmers use the same terminals for the same functions, It looks likely that they will be the same, but to be certain you need to tell us:

1. The make and model of the programmer you currently have that you want to replace.

2. You will need the dual channel version of the Hive. Is that what you have?

3. Do you have an existing room thermostat, and if so how do you anticipate decommissioning it so that it doesn't interfere with the operation of the new Hive. You can't just disconnect its wiring as it would leave the heating wiring 'open circuit' and it wouldn't work. You can ignore this bit if you don't have an existing room thermostat.

Hi Stem,

Thanks for your reply. I've attached images as they explain more than words:

We do have a thermostat. Can we just leave it in place? I read leaving it in place and turning it toax is an option?

I spoke with Hive and they sent me the unit which I needed. The only information I can find is: 'for use if you have a separate bathwater tank

Thanks

I've just confirmed, it's dual.

Thanks. In that case, they are the same as you can see below:

Danfoss CP715-Si

And you can leave the existing thermostat in and set on maximum, if you like. Hopefully it won't get moved.

Perfect, thanks, makes life very easy!

If I decide to take the old thermostat off, what would I do with the wires?

Many thanks.

The thermostat can be decommissioned in three ways. The first method is how a professional installer would do it. You have already worked out number 3.

1. Find the origin of the thermostat cable, notice where the wires are connected and disconnect them. Then link the terminals where the two switching wires previously originated from together.

2. Remove the existing thermostat and replace it with a junction box, connect the two switching wires together and isolate the neutral (if there is a neutral present)

3. Leave the existing room thermostat in place and fix it so that it is set to the highest setting. (Or put both of the switching wires in the 'Live' terminal, and isolate the Neutral, if there is a neutral present)

If you decide to do it later, and require more assistance, post back details of the wiring connections at the existing thermostat.

We've seen this problem before

Success last night! Very easy, many thanks.
