Please follow these safety instructions closely to
prevent accidents and material losses.
Safety instructions explained
Danger
This symbol warns against the risk of injury.
!Please note
This symbol warns against the risk of material
losses and environmental pollution.
Note
Details identified by the word "Note" contain additional
information.
Target group
These instructions are exclusively intended for quali-
fied contractors.
■Work on the refrigerant circuit may only be carried
out by authorised refrigeration engineers.
■Work on electrical equipment may only be carried
out by a qualified electrician.
■The system must be commissioned by the system
installer or a qualified person authorised by the
installer.
Regulations to be observed
■National installation regulations
■Statutory regulations for the prevention of accidents
■Statutory regulations for environmental protection
■Codes of practice of the relevant trade associations
■Relevant country-specific safety regulations
Safety instructions for working on the system
Working on the system
■Isolate the system from the power supply, 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 reconnection.
■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.
■Never touch hot surfaces on the appliance, fit-
tings or pipework.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing work, touch earthed
objects such as heating or water pipes to dis-
charge static loads.
Repair work
!Please note
Repairing components that fulfil a safety func-
tion 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 tes-
ted together with the system can compromise its
function. Installing non-authorised components
and making non-approved modifications or con-
versions can compromise safety and may inva-
lidate 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 electrocution.
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.

These service instructions include the following infor-
mation regarding the Vitotronic 200, type WO1C heat
pump control unit for air/water heat pumps with sepa-
rate indoor and outdoor unit:
■Function description
■Control parameters for matching the heat pump to
different requirements and operating conditions
■Diagnosis options for heating system and refrigerant
circuit
■Troubleshooting measures
■Overview of electrical connections
The functions and control characteristics of the heat
pump control unit are matched to the relevant heat
pump by means of the coding card. As a conse-
quence, the full scope of functions described here is
not necessarily available for every heat pump type.
In addition, the selected system scheme and the auxili-
ary equipment also influence the functions available in
the heat pump control unit.
Type or system-specific details are only highlighted in
those places where they have a direct effect on the
characteristics of the heat pump or the heating system.
System examples
System examples with hydraulic and electric connec-
tion diagrams as well a detailed function description
are available to aid the understanding of the heat
pump control unit function.

Air/water heat pumps for indoor and outdoor installation, monoblock version
All components of the refrigerant circuit are installed in
a single appliance.
Heat pumps for indoor installation
The heat pump is supplied with outdoor air via an air
duct. Expelled air leaves the building via another air
duct.
The refrigerant circuit has a variable speed compres-
sor. The secondary pump, the 3-way diverter valve
"central heating/DHW heating" and the heat pump con-
trol unit are built into the heat pump.
Heat pumps for outdoor installation
The heat pump is installed outdoors. The building is
heated or cooled via the hydraulic connection lines.
These hydraulic connection lines, together with the
electrical connecting cables, are laid in the ground with
frost protection.
The heat pump control unit is located in a separate
enclosure inside the building. The hydraulic compo-
nents for distribution in the secondary circuit, such as
the secondary pump, are also installed in the building.
