Help! Hive Installation - Worcester Bosch greenstar heatslave ii 18/25

[Zman]

Hi All,

I have been given a Hive 2 With Dual Channel Receiver.

I would like to use it with my Worcester Bosch Greenstar Heatslave ii 18/25

After reading around online I am aware that the single receiver version should be used for Combi boilers. However it can also be seen a Dual Channel receiver can be successfully used for this purpose. (Also as this was gifted from a friend I have no option to return or exchange)

Currently fitted with Drayton DT20RF/LP20RF

Ideally I would still like to control the Hot water On/Off via Hive App if need E.g at night

Please can some one advise on how this should be wired up? (Possibly by annotating my wiring diagram?)

Attached is an image showing the existing wiring and a diagram for possible annotation.

Any help would be hugely appreciated as I am going cross eyed.

did your friend previously use it ? or was it a unopened box with a fresh register code

Thank you for your response. It has been used. I had not got as far as to look at pairing A quick google suggests Hive will not re register?

It can be done you need some 5 core flex.

Connect live, neutral and earth on the Hive to L N E on the orange plug in the boiler.

3 on the Hive to HW, and 4 to CH on the yellow plug.

Then you will need to disconnect the ribbon cable behind the clock from the plug that it is plugged into.

To sign into the app you would need your friend sign in details or a new hub of you can't use them.

It wont , but you do not need to change everything, some of it you can re-use

hi do i leave the live loops on boiler in position or remove them many thanks i have 2x 1 live to hw and l to ch

 

[ianmcd]

you have to remove the ribbon from the DT20 or it will over ride your hive

 

[simon dorras]

sorry im aware you have to remove ribbon but there are two loops on the boiler between live and hot water and live and central heating as per pic do i remove these loops before fitting hive many thanks

 

[Johnmdc]

Yes if your fitting the dual channel Hive. Or only the one between L and CH if your fitting the single channel one.

 

[simon dorras]

many thanks so using the single channel hive i leave the loop in place between live and hot water remove live central heating sorry but a bit lost so live neutral n and earth is pretty straight forward i then need 3 and 4 on hive to ch and hw on boiler am i correct with this

 

[Johnmdc]

Yes leave the link form L to HW.
No if using a single channel there is no connection to hot water.
Boiler - Hive
N - N
L - L
Link L - 1 on the receiver
CH to 3
