Setting the time program for DHW heating
Factory setting: one time phase from 00:00 to 24:00 h
for every day of the week with the "Top" operating sta-
tus
1. Extended menu:
2. "DHW"
3. "Time program DHW"
4. Set the required time phases and operating status.
To see how to set a time program: see page 21.
Note
■
The DHW is not heated between the time phases.
Only frost protection for the DHW cylinder is active.
■
When setting time programs, bear in mind that your
heating system requires some time to heat the DHW
cylinder to the required temperature. Select a corre-
spondingly earlier start time. Use the "Start optimi-
sation" and "Stop optimisation" functions: see
pages 34 and 35.
■
Your rooms will not be heated whilst the DHW cylin-
der is being heated.
Operating status for DHW heating
The operating statuses for DHW heating differ as fol-
lows depending on the type of DHW cylinder you have
installed:
DHW cylinder with a temperature sensor at the top
"Top"
■
The top section of the DHW cylinder is heated to the
"Set DHW temperature", e.g. when there is little
DHW demand: see page 33.
"Standard"
■
The top section of the DHW cylinder is heated to the
"Set DHW temperature": see page 33.
"Temp. 2"
■
The top section of the DHW cylinder is heated to the
"Set DHW temperature 2": see page 33.
DHW cylinder with two temperature sensors
Applies to the following versions:
■
DHW cylinder with temperature sensors at the top
and bottom
■
Heat pump with integral DHW cylinder
"Top"
■
The top section of the DHW cylinder is heated to the
"Set DHW temperature", e.g. when there is little
DHW demand: see page 33.
"Standard"
■
The entire volume of the DHW cylinder is heated to
the "Set DHW temperature": see page 33.
"Temp. 2"
■
The entire volume of the DHW cylinder is heated to
the "Set DHW temperature 2": see page 33.
Note
Your contractor will have listed the equipment and
functions of your heating system in the form on
page 97.
For questions relating to the extent of functions and
accessories for your heat pump and your heating sys-
tem, check with your contractor.
Setting start optimisation
Start optimisation ensures that DHW is available at the
set temperature at the beginning of a time phase in the
time program.
1. Extended menu:
2. "DHW"
3. "Start optimisation"
Example:
From 06:00 h, hot water for showering is required.
Set the start of the time phase in the time program to
06:00 h. With start optimisation, DHW heating starts
automatically earlier than this.
This makes DHW available at the set temperature at
06:00 h.
