radiators taking long time to heat up in party mode overide

pellattuk · 28 Sep 2010

I have a Viessmann Vitodens 200 Boiler with Vitotrol 300 controller which has been installed for about 5 years.
It works fine in normal programmed mode, but if we need to put into overide with the party mode setting it takes about an hour for the radiators to come up to heat.
I do not know if it has always been like it as it has always been on timed control, but now I have retired I need to put it on occasionally outside of normal programme times.

Any ideas please.
