"I want hot water"?

[JohnnyZero]

In the ViCare app, I see there is a quick selection called "I want hot water". I assume this will do a one-time DHW preheat, and allow the hot water to come up to temp a bit quicker prior to taking a shower, running my dishwasher, etc?

Any further information or enlightenment on this feature will be greatly appreciated. Thanks!

From my experience: no preheat, just warming up the water to the set temperature.  I find it useful when hot water is available based on a schedule, and you want hot water outside the interval during which the hot water schedule is active. 

Hope this helps.

Hello

Hot Water will be warmed only outside the defined schedule if the current température is below the température defined less the defined delta

Current T° : 52,5

Defined t° : 52

Delta defined : 1°

If you press "i want hot water" the water will be warmed when the t° will be below 51°

If you want to produce hot water you will have to increase the defined T° 1° above 52,5 ° in my example

This is the logic of the viessmann developpers

As you i was hoping that the water will be warmed independently of the schedule and  independently of the current T° till the defined T° plus 2,5°

----------------------------------------------------------------------------------------

I suggest you have a look at "i want warm longer" when you have people staying later than the programmed warning schedule

If the hot water curent température is below 51° in my example; the hot water will be warmed before you will be able to heat the room as if the people you invited at home needed to take a shower before continuing to discuss with you

This is also the logic of the viessmann developper; the probably did not use the material they sell

When i purchased my vitodens 200 in July 2019, the user manual describe the desired behavior, the previous heating phase will be prolonged

I signalled this problem to Viessmann Belgium and they told me that "warm longer" was previously called "reception mode" and that it has always worked like this and that this was an error in the manuals (in all languages)

So someone described what we want as behavior but the developper and the tester did not read the user's manual

and now they have changed the manual in order to describe this silly behavior
