Energy Saving Tips - Viessmann Vitocal 060-A Operating Instructions For The System User

Permissible air intake temperatures
The DHW heat pump shuts down outside the permissi-
ble air intake temperatures. In some operating pro-
grams, DHW can also be heated outside the permissi-
ble air intake temperatures, through the use of an
immersion heater (accessories). With type T0S-ze, an
external heat generator can be connected.
Commissioning
The commissioning and matching up of the heat pump
control unit to local conditions and to the structural
characteristics of the building, plus the instruction of
the user in operating the system, must be carried out
by your heating contractor.
Your system is preset at the factory
Your DHW heat pump is preset at the factory and is
therefore ready for operation.
DHW heating
DHW is heated every day from 00:00 to 24:00 h to
■
53 °C (set DHW temperature).
Day and time
■ The day and time have been set by your contractor.

Energy saving tips

Saving energy on DHW heating
■ At night or during regular absences, heat the DHW to
a lower temperature. To do so, adjust the time pro-
gram for DHW heating: See page 13.
Disable automatic DHW cylinder reheating by the
■
immersion heater. Enable the "ECO" operating pro-
gram: See page 10.
Tips for greater comfort
DHW heating
Adjust the time program for DHW heating so that
■
there is always sufficient hot water in accordance
with your habitual routines: See page 13.
Example:
You need more DHW in the morning than in the day-
time.
Use the immersion heater (if installed) for automatic
■
DHW cylinder reheating. Enable the AUTO operating
program.
Permissible air intake temperatures:
■ For DHW heating in recirculation air mode and recir-
culation air mode with air discharge to the outside
(temperature in the installation room):
3 °C to 35 °C.
■ For DHW heating in outdoor air mode (outside tem-
perature):
-5 °C to 35 °C.
You can change the settings at any time to suit your
individual requirements.
Power failure
All settings are retained for 24 hours if there is a power
failure.
Utilisation of power generated on site (in conjunc-
tion with a photovoltaic system)
■ Use the power generated by your photovoltaic sys-
tem for your DHW heat pump (see page 15).
For additional energy saving functions of the heat
pump control unit, please contact your contractor.
■ Quick heat-up "bOOST" (only in conjunction with
an immersion heater; see page 11):
You can heat up the DHW cylinder immediately,
regardless of the time program. Enable the
"bOOST" operating program.
■ Immersion heater (if installed):
Use the immersion heater at low ambient or outside
temperatures, or if the DHW heat pump develops a
fault, for example.
