Hive Multizone Wiring

[Russep00]

I need some help to confirm how my system should be wired.

I have a new Ideal Boiler (hot water tank system) and I'm replacing existing controls with a Hive. Also added an underfloor heating zone in a new extension. Three 2-way valves installed (radiators, water, underfloor).

Problem is that the hot water works fine but no heating from either the rads or the underfloor - pump does not activate.

Prior to the underfloor system being wired in the Hive controlled the water and rads no problem, but since the extra controller has been wired in we have no heating at all from either zone.

Any ideas what has been done wrong or what to check?

I should note that a professional electrician has done the install but this is his first Hive system and as the underfloor has been added on he's a bit unsure.

Do the rads /under floor heating zone valves open when there is a call for heat ?

No it seems no life at all

Assuming your electrician has wired it correctly has he followed the instructions ?

Yes the hive sends all the right signals but the boiler doesn't fire when there's a call for heating. Works fine for hot water

Switched lives for the heating zones are wrong then.
