1Safety
This chapter contains information on:
•the proper use of the controller and
•the safe use of the controller.
Read this chapter through carefully before you install, connect or operate the controller.
1.1 Proper use
The controller is used for monitoring and controlling a heating system.
Appropriate use of the controller includes the following requirements:
•Use the controller exclusively in dry rooms in residential, commercial and/or industrial
environments.
•Use only sensor connection boxes supplied by the manufacturer.
•Use the RS485 interface (ProBusX) only for networking further devices from the
manufacturer Prozeda.
The definition of proper use also encompasses observing and complying with all of the
information contained in this manual - in particular compliance with all safety information
and instructions.
Any other use, or any use exceeding the specifications, will be deemed to be improper use
and may lead to personal injury or damage to property and shall render the warranty void.
Use of the controller in the following situations in particular is considered to be improper
use:
•If you modify the controller independently and without prior authorisation
•If you operate the controller in a humid or wet environment
The manufacturer shall not be liable for damages arising from inappropriate use.
1.2 Basic safety information
This section contains basic safety information relating to working with the controller. You
will find additional safety information relating to specific actions and workflows at the
beginning of the section concerned.
Preventing risks of explosion
•Never use the unit in areas where there is a risk of explosion.

Safety

Preventing risks of fatal injury from electric shocks
•ake sure that all regulations applicable at the point of use are complied with.
•Always make sure that the controller is disconnected from the power supply before
carrying out any work on it.
•ake sure that the connections of the protective extra-low voltage areas do not get
mixed up with the power supply connections.
•On completion of installation work, refit the terminal cover and tighten the locking
screw using a screwdriver.
•ake sure that the electrical connection of the controller can be disconnected from the
mains externally if required.
•ake sure that all cables are secured by strain relief devices.
•Use the device only if it is in a fault-free condition.
Preventing risks of fire
•Install the controller on a non-flammable subsurface.
Preventing risks of injury from burns
•Carry out installation work on the heating system only when it has cooled down.
•The process water can reach very high temperatures. Exercise particular care when
configuring settings on the controller.
•Take water samples after completion of the settings and check them using a suitable
thermometer.
Preventing damage to property
•A damaged controller may cause malfunctions in the system as well as damage to its
components. Use the controller only if it is in a fault-free condition.
•Install the controller with due observance of its protection class. Information about this
can be found in the chapter Technical Data from page 25 onwards.
•ake sure that no moisture gets into the controller.
•If any moisture gets into the controller, disconnect the controller from the power
supply.
•ake sure that the maximum permissible ambient temperature is not exceeded.
Information about this can be found in the chapter Technical Data from page 25
onwards.
•ake sure that all components to be connected to the switching outputs are suitable
for an operating voltage of 230 V/50 Hz.

Description of the controller
8
•When in "manual mode", the system must only ever be operated for a short time and
only for test purposes.
•Install sensor lines separately from 230 V lines.
•Use only sensor connection boxes supplied by the manufacturer.
2Description of the controller
The controller is used for monitoring and controlling a heating system. The controller
allows the system to be configured in accordance with the local situation at the place of
use and with the requirements of the user. In addition, the controller can be used to carry
out system protection functions.

DANGER
Risk of fatal injuries due to explosions or fire.
Never use the controller in areas where there is a risk of explosion.
Install the controller on a non-flammable subsurface.
DANGER
Risk of fatal electric shock when working on the opened controller.
ake sure that the controller is disconnected from the mains voltage
before removing the terminal cover.
ake sure that the power supply has been secured to prevent it from
being switched on again.
Check that the controller is free from voltage.
Screw the terminal cover securely back in place when work has been
completed.
ATTENTION
Risk of damage and malfunctions due to improper storage before
connection.
Store the controller at room temperature for at least four hours before
connecting it.
Select an installation location which meets the following requirements:
•The installation location must be at eye level.
•It must have access to the power supply.
•There must be sufficient space in front of the controller to allow it to be operated.

3.1 Fastening the controller
If you wish to lead cables and lines through the back of the controller, you need
to
do this before you fasten it.
ATTENTION
Risk of damage to the controller housing due to screws tightened too
firmly.
Tighten the screws only as firmly as necessary.
Use only suitable screws and dowels for fastening the controller.
Hang the controller on the top screw by the keyhole (1).
Fasten the controller with the screws from the inside through the bottom screw holes
(2).
