Dhw Heating Outside The Time Program - Viessmann VITOCAL 300-G Operating Instructions Manual

Setting the time program for DHW heating
Start optimisation
Start optimisation ensures that DHW is
available at the required temperature at
the beginning of a time phase.
Note
This function is only active if a time pro-
gram has been set.
Extended menu:
1.
2. "DHW"
3. "Start optimisation"
Example:
From 06:00 h you require hot water for
showering.
You set the start of the time phase to 6
o'clock. With the start optimisation, DHW
heating automatically starts a little ear-
lier, so that hot water is available at the
required temperature at 6 o'clock.

DHW heating outside the time program

You can start DHW heating immediately
either with the "DHW heating once
only" or with the "Comfort function"
("Party mode") independently of the time
program.
DHW heating once only
DHW is heated once to the "Set temper-
ature 2" (see page 29).
Standard menu
1. "DHW"
2. "1 x DHW heating"
(cont.)
Stop optimisation
The stop optimisation ensures that the
DHW cylinder is always fully heated at
the end of the time phase with the oper-
ating status "Normal".
Note
This function is only active if a time pro-
gram has been set.
Extended menu:
1.
2. "DHW"
3. "Stop optimisation"
Note
Heating DHW once only terminates
automatically when the "Set temperature
2" has been reached.
DHW heating with the comfort func-
tion ("Party mode")
The DHW cylinder will be heated to the
standard DHW temperature if the com-
fort function ("Party mode") has been
started (see page 26).
