Can Anyone Help With my VRT 392 and How to Reheat the Hot Water (438 Heat only)

[Richard at Home]

I have just installed a Vaillant VRT 392 controller on my wall using the BUS Cable

I have a 438 Heat only Boiler system ( Not combie )

How do i turn on the hot water as a Temp Recharge at any point in the day just for the Hot water

I know how to program the hot water in as part of the time periods

But i am trying to find how to just turn on the hot water for a 30 mins to Reheat an additional tank of hot water

Does this function not exist on this control unit

Thanks

Richard

Pain in the backside as it is vaillant controls are very good but notoriously difficult to set up you will probably save yourself a lot of time in the long run if you actually call the Vaillant helpline
