Hive and Drayton Digistat 2

[savgeax]

Good evening,

I am in the process of installing the Hive Receiver and just need to replace the Drayton Digistat 2.

Can anyone advise, having looked at the pictures attached, what wires should go where? I have a Baxi combi boiler.

The wires going into Digistat, are only common and on. The hive receiver appears to need an off aswell.

Any help on this would be appreciated.

The wires at the Drayton Digistat 2 terminals move to the terminals at the Hive that have the same function. For a Combi boiler you need the single channel version of the Hive, and move the wires over as follows:

Digistat (L) = Hive (L)
Digistat (N) = Hive (N)
Digistat (C) = Hive Common (1)
Digistat (On) = Hive Heating ON (3)

That's all you need, the other terminals are not used. Your present thermostat doesn't have a wire in its 'off' terminal, so you won't need it at the Hive either.

Thank you for your quick response.

You say Hive need four wires, however the digistat is basically three (Live, Neutral and On). The common connection gets a link from the live on the digistat, as per the picture in my first post.

Hope that makes sense? or am I mis understanding something

your hive will work if wired the same way , on to 3 and link live and 1 at the hive, to others reading this post this is not suitable for all boilers but as yours is already wired this way it will be ok

You say Hive need four wires

Not exactly. I said that 4 of the terminals will need to have wires in, which they do:

Hive (L)
Hive (N)
Hive Common (1)
Hive Heating ON (3)

however the digistat is basically three (Live, Neutral and On).

It does have three wires, but still four terminals are used. The same as the Hive.

Digistat (L)
Digistat (N)
Digistat (C)
Digistat (On)

Electrically speaking, there is no difference between the two thermostats. Their terminals are even labelled the same (Digistat 'C' = Hive 'Common') (Digistat 'On' = Hive 'Heating On') you are simply swapping thermostats that are electrically like for like.

The common connection gets a link from the live

It does and so will the Hive. The link is included in the wires to be moved to the Hive.
