Controlling manifold pumps from Ecodan outputs

[ADringer]

Hi,

 

I currently have a Ecodan and a manifold. This was originally wired up so that if a room stat calls for heat then this will trigger the circulation pump on the manifold and the heat pump itself.

 

I don't want to do this, as this could result in only one room running at a time and so poor performance, and I would like to control it remotely via MELCloud.

 

Basically, I want to reverse this - when the heat pump turns on, turn on the manifold pumps. Looking at the wiring diagram, there are outputs on the Ecodan board (OUT1,2,3) which I believe I can hook the pumps up to so that the Ecodan is the master. 

 

Has anyone else wired it up like this?
