Worcester, Greenstar Ri problems

[Scornio]

Thanks for all advice...

Turns out both ways worked... Although wired it the correct way with regards to taking feed to pump via boiler rather than before boiler.

thanks again.

"Hello again Scornio",

This message is only to try and prevent other Readers from getting misled / confused about the Pump Over-run:

The Pump Over-run is ONLY Controlled by the Boiler - when the Heat is dissipated from the Heat Exchanger the Pump Over-run is turned Off.

That is the ONLY way that the Pump Over-run can be Operated - I think that this process is controlled by Thermistors within the Boiler.

I am NOT any kind of Expert in Electrical Wiring / Installation - BUT - I know that the Pump MUST be wired to dedicated Terminals within the Boiler - identified in the Installation Instructions.

I do NOT know whether a Different / incorrect configuration of Wiring can cause the Pump Over-run to operate `Correctly` - but I very much doubt it.

I am glad to read that You got it sorted out.

Regards,

Chris - Heating Engineer

Pleased you got it sorted and yes - connecting to the boiler IS the way to go for the reasons given by Chris.
