and all locally applicable standards
Workingonthesystem
&Isolate the system from the power
supply and check that it is no longer
'live', e.g. by removing a separate
fuse or by means of a main isolator.
&Safeguard the system against
unauthorised reconnection.
!Please note
Electronic modules can be
damaged by electrostatic dis-
charges.
Touch earthed objects, such as
heating or water pipes, to dis-
charge static loads.

This manual explains the function, control parameters and fault messages of
the WPR 300 heat pump control unit for Viessmann heat pumps.
With the control parameters, the heat pump can be matched to varying demands
and operating conditions. To avoid incorrect operation of the heat pump or other
system components, the control parameters and fault messages are available
at three different setting levels.
Setting levels
&"System operator":
Individuals who have been trained
in the operation of the heating sys-
tem by heating engineers (contrac-
tors).
&"Contractor":
Heating engineers who have been
trained the use of Viessmann heat
pumps.
&"Expert":
Heating engineers who have com-
pleted specialist expert training for
Viessmann heat pumps.
Designation
After switching on, the setting level
"System operator" is automatically
enabled. Access to the "Contractor"
and "Expert" levels is gained by enter-
ing an access code. Control para-
meters and fault messages which are
only accessible at the "Contractor"
and "Expert" setting levels, are indi-
cated in this manual with the following
symbols:
!Available at the "Contractor" and
"Expert" setting levels. Control
parameters are displayed as plain
text.
§Only available at the "Expert" set-
ting level. No plain text display;
control parameters are identified
by numbers.
Control parameters and fault mes-
sages at the "System operator" set-
ting level have no special
identification, since they are available
without entering a code.
Note
All functions and settings are avail-
able at the "Expert" setting level. The
"Contractor" level includes the
"System operator" level.
