Safety instructions for working on the system
Working on the system
■Isolate the system from the power sup-
ply, e.g. by removing the separate fuse
or by means of a mains isolator, and
check that it is no longer live.
Note
In addition to the control circuit there
may be several power circuits.
Danger
Contact with live components can
result in severe injuries. Some
components on PCBs remain live
even after the power supply has
been switched off.
Prior to removing covers from the
appliances, wait at least 4 minutes
until the voltage has completely
dropped out.
■Safeguard the system against recon-
nection.
■Wear suitable personal protective
equipment when carrying out any work.
Danger
Hot surfaces and fluids can lead to
burns or scalding.
■Before maintenance and service
work, switch off the appliance and
let it cool down.
■Do not touch hot surfaces on the
appliance, fittings or pipework.
!Please note
Electronic assemblies can be dam-
aged by electrostatic discharge.
Before beginning work, touch
earthed objects, such as heating or
water pipes, to discharge any static.
Work on the refrigerant circuit
Refrigerant R1234ze is a colourless,
odourless gas that displaces air.
■R1234ze is mildly flammable (safety
class A2L according to ISO 817).
■R1234ze belongs to fluid group 2
(according to the Pressure Equipment
Directive 2014/68/EU).
Danger
Direct contact with liquid and gas-
eous refrigerant can cause serious
damage to health.
■Avoid direct contact with liquid and
gaseous refrigerant.
■Wear protective gloves/protective
clothing/eye protection/face pro-
tection (P280).
■Wear respiratory protection
(P284).
■If exposed or concerned: Get
medical advice/attention
(P308+P313).
■Protect from sunlight and store in
a well ventilated place
(P410+P403).
Details in brackets pursuant to
Regulation (EC) No 1272/2008
Danger
Contains gas under pressure; may
explode if heated (H280).
Do not heat the refrigerant circuit
from the outside.

Danger
Unregulated escape of refrigerant in
enclosed spaces can lead to
breathing difficulties and suffoca-
tion.
■Do not breathe dust/fumes/gas/
mist/vapours/spray (P260).
■Ensure adequate ventilation in
enclosed spaces.
Perform the following measures before
beginning work on the refrigerant circuit:
■Check the refrigerant circuit for leaks.
■Ensure very good ventilation especially
in the floor area and sustain this for the
duration of the work.
■Inform all persons in the vicinity of the
system about the type of work to be
carried out.
■Secure the area surrounding the work
area.
Danger
Damage to the refrigerant circuit
can cause refrigerant to enter the
hydraulic system. This can cause
serious damage to health.
After completion of work on the
refrigerant circuit, professionally
vent the hydraulic system on the
primary and secondary sides.
Repair work
!Please note
Repairing components that fulfil a
safety function can compromise the
safe operation of the system.
Replace faulty components only
with genuine Viessmann spare
parts.
Auxiliary components, spare and
wearing parts
!Please note
Spare and wearing parts that have
not been tested together with the
system can compromise its func-
tion. Installing non-authorised com-
ponents and making non-approved
modifications or conversions can
compromise safety and may invalid-
ate our warranty.
For replacements, use only original
spare parts supplied or approved by
Viessmann.
Safety instructions for operating the system
What to do if water escapes from the
appliance
Danger
If water escapes from the appliance
there is a risk of electric shock.
Switch off the heating system at the
external isolator (e.g. fuse box,
domestic distribution board).
Danger
If water escapes from the appliance
there is a risk of scalding.
Never touch hot heating water.

Intended use
The appliance is only intended to be installed and
operated in sealed unvented heating systems that
comply with EN 12828, with due attention paid to the
associated installation, service and operating instruc-
tions.
The appliance may only be used for heating DHW.
The range of functions can be extended with additional
components and accessories.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial use for purposes other than
domestic hot water heating shall be deemed inappro-
priate.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.

Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and will result in an exclusion of liability. Incorrect
usage also occurs if the components in the heating
system are modified from their intended function.
Note
The appliance is intended exclusively for domestic
use, i.e. even users who have not had any instruction
are able to operate the appliance safely.
Product information
Vitocal 060-A
A DHW cylinder is integrated into the type T0E-ze
DHW heat pump.
The heat pump uses the thermal energy in the indoor
or outdoor air for DHW heating.
At times of peak DHW demand, an immersion heater
can provide reheating (fitted at the factory for type
T0E-ze; accessory for type T0S-ze).
Type T0S-ze contains the full function range of type
T0E-ze. In addition, a solar thermal system or external
heat generator (e.g. oil/gas boiler) can be connected.
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 ambient temperature
(indoor air in the installation room) is used for DHW
heating.
When DHW is being heated, the installation room is
cooled and dehumidified.
Recirculation air mode with air discharge to the
outside
Ambient air is supplied to the DHW heat pump. A sep-
arate outdoor air aperture simultaneously allows out-
door air to enter the room.
The ambient air that is cooled down during DHW heat-
ing is routed outdoors by the DHW heat pump.
Outdoor air mode
In outdoor air mode, outdoor air is supplied via a duct.
The outdoor air that is cooled down during DHW heat-
ing is routed outdoors by the DHW heat pump.
Outside temperature limits
Note
What DHW temperature the heat pump can achieve
depends on the outside temperature.
The maximum achieved is 62 °C.

AMaximum DHW temperature achievable by the

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.
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.

Transport and siting
!Please note
Impacts, compression and tensile loads can
cause damage to the outside panels of the
appliance.
Never put weight on the top or front of the appli-
ance or cylinder jacket.
The DHW heat pump can be transported vertically or
horizontally.
Note for horizontal transport
Position the DHW heat pump. Allow the DHW heat
pump to stand for at least 24 hours before commis-
sioning.
Lifting straps (accessories) are available to facilitate
transport.
Installation room requirements
■The installation room must be dry and free from the
risk of frost.
■The intake air must be kept free from dust, grease
and contamination through halogenated hydrocar-
bons (e.g. as contained in sprays, paints, solvents
and cleaning agents).
■To prevent the transmission of structure-borne noise,
never site the appliance above ceilings with wooden
joists (e.g. in the attic).
■A separately fused standard power socket must be
available.
■A condensate drain pipe must be available.
■Always maintain the minimum clearances for service
and maintenance work.
