Hive wiring to grant boiler

[daf12234]

Hi, having a bit of trouble

Boiler has a manual timer fitted that has never been used, do I wire the hive up to that or remove the link between 7 and 12 and put it there.

What model Grant? On some of early combi's hot was permanently on.
Which model hive have you got?

Its a Combi 70 mk2

Okay so update, I've got it working, but if I turn the boiler thermostat up it bypasses the hive and turns the heating on constant, so I'm only able to use the hive with the low heat setting on the boiler?

Take your wiring from the plug in timer,

1 on timer to N on hive
2 on timer to L on hive
5&6 on timer to 1&3 on hive (either way round doesnt matter)

13 & 14 there should be a link which looks like it’s been taken out already…. Connect 1 & 3 of hive to 13 & 14 of boiler.
