usage instructions
1.1 General safety notes
Carefully read the operating manual before com-
missioning the units for the first time. It contains
useful tips and notes such as hazard warnings to
prevent personal injury and material damage.
Failure to follow the directions in this manual not
only presents a danger to people, the environment
and the system itself, but will void any claims for
liability.
Keep this operating manual and the refrigerant
data sheet near to the units.
1.2 Identification of notes
This section provides an overview of all important
safety aspects for proper protection of people and
safe and fault-free operation.The instructions and
safety notes contained within this manual must be
observed in order to prevent accidents, personal
injury and material damage.
Notes attached directly to the units must be
observed in their entirety and be kept in a fully
legible condition.
Safety notes in this manual are indicated by sym-
bols. Safety notes are introduced with signal words
which help to highlight the magnitude of the danger
in question.
DANGER!
Contact with live parts poses an immediate
danger of death due to electric shock. Damage
to the insulation or individual components may
pose a danger of death.
DANGER!
This combination of symbol and signal word
warns of a situation in which there is immediate
danger, which if not avoided may be fatal or
cause serious injury.

4.2 Electrical wiring
DANGER!
Danger to life and limb due to electric
shock!
Ensure that the following conditions are met
when carrying out the works described in this
section:
- During installation, all cables to the controller
must be disconnected from the mains and
cannot be inadvertently connected to the mains!
- The earth conductors (PE) from the power
supply, pump cables and valve cables are con-
nected to the terminal block earth conductors.
- All cables are located so that people cannot
step on them or trip over them.
- The cables fulfil the requirements specified in
the “Technical data” section.
- The local power supply matches the data on
the name plate of the controller.
- The power supply cable is to be connected to
the mains as follows:
-- with a plug to a wall socket or
-- via an isolating device for full isolation in fixed
locations.
- The power supply cable is located according
to the legal and local regulations of the respon-
sible electricity supply company.
NOTICE!
Danger of damage and malfunction!
–Only connect components that do not over-
load the inputs and outputs of the controller;
for more information, see the name plate
and “Technical data” section.
NOTICE!
Danger of damage and malfunction!
–When using a circulation pump, the current
consumption of the pump connected to the
controller must always be observed and the
current consumption matched to the con-
troller. In some cases the circulation pump
must be supplied directly via the power
supply. The speed is also controlled via the
PWM signal.
Important information
nThe polarity of signal inputs/outputs 1 – 4 is not
fixed during connection.
nOnly temperature probes of type Pt1000 are
permitted.
nProbe cables must be located at least 100 mm
away from power supply cables.
nUse shielded probe cables if inductive sources
are present, e.g. high-voltage cables, radio
transmitters, microwave units.
