Product information
Vitocal 060-A, type T0E
The Vitocal 060-A, type T0E, is a DHW heat pump with
integral DHW cylinder.
The heat pump uses the thermal energy in the indoor
or outdoor air for DHW heating.
An immersion heater can provide booster heating
when the DHW demand is at its highest.
The heat pump is available for recirculation air
mode, outdoor air mode and recirculation air mode
with air discharge to the outside.
Recirculation air mode
In recirculation air mode, the thermal energy from the
ambient air (indoor air in the installation room) is used
for DHW heating. The air cooled down by this process
is discharged back into the installation room by the
DHW heat pump.
When DHW is being heated, the installation room is
cooled and dehumidified.
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.
Permissible air intake temperatures
The DHW heat pump switches off outside the permis-
sible 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).
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 to 54 °C (set DHW temperature)
■
every day from 00:00 to 24:00.
Day and time
■ The day and time have been set by your contractor.
Recirculation air mode with air discharge to the
outside
As in recirculation air mode, the DHW is heated with
the thermal energy from the indoor air. The cooled air
is discharged to the outside through a ductwork sys-
tem. At the same time, fresh air enters the installation
room through an outdoor air aperture.
Outdoor air mode
In outdoor air mode, outdoor air is supplied to the
DHW heat pump via a duct.
The air cooled down during DHW heating is dis-
charged directly to the outside via a further duct.
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.
