1 Proper usage
The fresh water controller, subsequently referred to as the controller, is an independently installed electronic temperature controller for on-surface installation. Integration
into a pump assembly is possible when the technical specifications of the controller are
adhered to.
The maintenance-free controller is exclusively intended for controlling and monitoring
fresh water stations.
2 About this manual
2.1 Contents
This manual contains all information required by a technical professional for setting up
and operating the controller.
2.2 Target audience
The target audience of this manual are technical professionals who:
• have the knowledge of terminology and the skills necessary for setting up and operating fresh water stations.
• have the necessary training, knowledge and experience, and knowledge of the applicable regulations in order to evaluate and recognise the dangers inherent in the
following work:
– Installing electrical equipment
– Cutting to size and connecting data communication cables
– Cutting to size and connecting mains grid power supply cables

Note
The following section describes only the installation of the
controller
tions of each respective manufacturer when installing external components (pumps,
3.1 Opening / Closing the casing
3.1.1 Removing the front panel
by the grooves at the sides
and pull forwards
(Fig. 1).
3.1.2 Mounting the front panel
and then press it onto the casing until it latches
3.1.3 Removing the terminal cover

3.2 Mounting the casing
√ The mounting location must satisfy the prescribed conditions of use; more informa-
tion on this is provided in the Technical data section.
√ The mounting surface is vertical and allows good access for installation.
Danger
Risk of death by electrocution!
• Disconnect the controller from the power supply before opening the casing.
• Make sure that the power supply cannot be unintentionally switched on when the
casing is open.
• Do not use the casing as a drilling template.
1. If necessary, remove the terminal cover
2. Screw in the screw for the upper mounting hole (Fig. 2) until the screw head has
a clearance of 5 ... 7 mm from the mounting surface.
3. Hang the controller on the screw by the upper mounting hole and align it vertically.
4. Mark the position of the lower mounting hole through the casing.
5. Remove the controller and prepare the mounting hole for the lower screw.
6. Hang the controller by the upper mounting hole and then fasten the screw in the
lower mounting hole .
7. Mount the terminal cover.

3.3 Establishing the electrical connections
Danger
Risk of death by electrocution! Make sure that the following conditions are satisfied
when performing the work described in this section:
• All cables leading to the controller must be disconnected from the power supply and
it must be ensured that they cannot be unintentionally reconnected during installation.
• Each connection terminal must only be connected to a single conductor.
• The protective earth conductors (PE) from the mains cable and pump and valve
cables must be connected to the protective earth conductor terminal block.
• All cables must be laid so that persons cannot stand on them or trip over them.
• The cables must satisfy the requirements listed in the Technical data section.
• The local power supply must match the specifications on the type plate of the con-
troller.
• The power supply cable is to be connected to the mains power as follows:
– using a plug connected to a wall mains socket or
– via an isolating mechanism allowing complete isolation in the case of permanent
wiring.
• The power supply cable must be laid in conformance to all applicable legal guidelines and regulations of the local electricity supplier.
Notice
Danger of damage and malfunction.
• Connect only components that do not overload the controller inputs and outputs;
more information is provided on the type plate and in the Technical data section.
• Speed control must be deactivated at output R1 when an external relay is con-
nected.
Notes
• Lay the sensor cables at least 100 mm away from any power supply cables.
• Use shielded sensor cables when inductive sources are present, e.g. high-voltage
lines, radio transmitters, microwave devices.
