no permanent live required in potterton boiler??

[egginyourface]

Ive just finished wiring up a potterton promax boiler and read in the manual that no permanent live was required in the boiler if the system is fully trv'd.



So basically there is no pump over run after boiler is shut down.

sorry if this a bit vague

Switch live will bring on pump overrun if required.

no permanent live required on this boiler, if all the rads have trv's then wire the pump up to pf terminal on the boiler to get pump overun.

or rather "pump control"
