Vaillant Ecotec 418 (2013) - How to turn up pump over run

[planemad]

Hi

is there a way that i can turn up the length of time of the pump over run on a 2013 ecotec.
I would like to boiler to dissipate a bit more heat around the system as it only drops 5c on the current over run.

i would like a few more minutes.
servicing is always done by Vaillant Group Service and not due until Aug 22 so if it's some that i can do myself i will do or i can wait till Aug.

thanks in advance.

No one replied so for reference searches I am adding a reply.

The setting for pump over run time is in setting d1 in minutes. From 1 min to 60 min

The factory default is 5 minutes.

I would expect, but am not sure, that the actual time could be more than the set value if the temperature is still too high.
