Sunvic wiring center 2202

[richardd]

I have just installed a greenstar 24 ri . I have disconnected the old oil boiler. The system has yplan control;s with wiring center. The problem is I dont know which connection is switched live or live return to the boiler on the wiring center as it is in a tight corner . There is 10 connectors block on it. I have wired the pump direct to the greenstar also no problens there.

Any Ideas

If the live return isnt connected would you get no voltage at the pump terminals in the control panel at the boiler ( np sp ) i think.
