3 Safety
The MATRIX control panel is manufactured in accordance with the state-of-the-
art engineering standards and established technical safety codes and regula-
tions.
The MATRIX control panels are for use intended by the manufacturer. Ensure
proper and reliable operation of the unit before use. Observe all relevant safety
instructions and precautions in the operation manual. Use proper safety mea-
sures to prevent hazardous situations which, if not avoided, could result in death
or serious injury to the user or property damage-only accidents!
Have all faults repaired by an authorized specialist without delay!
3.1 Identification of safety instructions
The following symbols and notices are provided in appropriate places throughout
this document to designate the safety instructions.
3.2 Safety-conscious work procedures
Observe the following instructions when carrying out installation, adjustment or
repair work:
When carrying out work near low-voltage networks
When carrying out adjustment work on the MATRIX control panel
ELECTRICAL HAZARD!
This symbol indicates a risk of electric shock when working on the equipment.

control panels.
DAMAGE TO THE UNIT!
This section specifies procedures and precautions for preventing damage to
the MATRIX control panels.
PERSONAL INJURY!
This section specifies procedures and precautions for preventing personal
injury.
ELECTRICAL HAZARD!

parts. Non-compliance can lead to death or serious injury.

Safety MATRIX control panel
10 PR-2011-0110-GB • Subject to modifications • R9-03-2016
For all kinds of work:
•Observe all assembly instructions for the MATRIX control panels.
•Fluctuations and imbalances in the supply voltage may not exceed the
tolerance limits specified in the technical data, otherwise functional failures
and limit states cannot be excluded.
3.3 Proper use
The MATRIX control panel is specifically designed for controlling air treatment
units manufactured by DencoHappel and depending on the equipment version,
regulating other units within a building automation system.
According to the hardware version, the MATRIX control panel is used:
– to assign setpoints for room temperature
– to assign setpoints for supply air temperature
– to select fan speed
– to assign operating mode (e.g. normal, economy mode)
– to assign controller operating mode (changing between heating and cooling)
– to set mixed-air or recirculating-air mode
– to perform regulation of remote building automation system, e.g. damper or
lighting control.
The MATRIX control panels are shipped in two protection types which protect the
unit against external effects:
Protection IP20
residential area – In protection type IP20 according to DIN EN 60529 for residential areas. May only be used indoors; in this case - ensure that the unit is protected
against dust and other substances.
Protection IP54
industrial area – In protection type IP54 according to DIN EN 60529 for industrial areas. The casing is dust-proof and protected against splash water.
Proper use also stipulates the observance of the current operation manual as well
as the inspection and maintenance intervals specified by DencoHappel.
Improper use Any use other than that described above is considered improper. The manufac-
turer/supplier is not liable for any damages arising from improper use. The user
alone bears the risk.
RISK OF ELECTROSTATIC DISCHARGE!
While carrying out adjustment work on the MATRIX control panel make sure
that you discharge yourself statically before manipulating PC boards and
installing electrical components.

4 Technical Description
4.1 Product features and functions
The MATRIX control panels are designed to control DencoHappel air treatment
units and are available in two types:
– Series OPxxC (Comfort) for normal environment (IP20) and
– Series OPxxI (Industry) for commercial/industrial environment (IP54).
Both series of control panels enable communication between the user and the
MATRIX control system.
OP5xx The OP5xx MATRIX control panels are equipped with MATRIX.Net bus, through
which communication with air treatment units is performed.
Display of OP5xx The MATRIX control panels with display enable a menu structure as plain text
from where users can directly access numerous functions of the DencoHappel
units. The menus are adapted dynamically according to the configuration of the
unit. Thus, menus are also available for access to remote systems such as
damper or lighting controls (only through MATRIX.LON).
NOTICE!
For further information about the MATRIX.Net refer to the operation manual of
the relevant air treatment unit.

5.1 Planning of mounting
Mounting MATRIX-
control panels/
room temperature sensor
* recommended
installation height = 1.5 m
ELECTRICAL HAZARD!
The electrical installation and (dis)assembly of the MATRIX control panel may
only be carried out by qualified electricians in compliance with the given oper-
ation manual and current VDE regulations.
•Before drilling, ensure that the drilling area is free from electrical cables and
pipes.
•Only indoor mounting of the MATRIX control panel is allowed.
•Do not connect the MATRIX control panel to an external voltage.
NOTE!
The installation site of the MATRIX control panel or room temperature sensor
is crucial for the precise measurement of room temperature.
Therefore the MATRIX control panels or sensors must:
– notbe fitted nexttodoors,windows,passages etc.,since intensemovement
of air can cause incorrect measurements,
– not be fitted on hot or cold walls (e.g. chimney, outside wall),
as wall temperature can cause incorrect measurements.
– not be fitted behind curtains or net curtains, since the insulating layers of air
can cause incorrect measurements,
– not befitted adjacent to unit discharge grilles as discharge temperature can
cause incorrect measurements
– not be fitted below cold surfaces like windows, since descending cold air
flow can cause incorrect measurements.

5.2 Mounting MATRIX OP50x/51x control panels
5.2.1 Mounting MATRIX OP5xC (IP20) control panel
The casing of the MATRIX OP5xC (IP20) control panel is designed for on-wall
and flush-mounted sockets.
•Useascrewdrivertoreleasethefrontpanel(1)fromthe
mounting plate (2) on the bottom side of the MATRIX
control panel.
NOTICE!
Use the drilling template for the wall mounting of the MATRIX control panels
(see "Drilling Templates" on page 102).
Make sure that the mounting plate is not deformed during installation.
NOTICE!
When mounting the MATRIX control panels in a flush-mounted socket, espe-
cially hollow-wall socket, ensure that nothing can impede the correct measure-
mentof the room temperature.Toavoiddraught,provideappropriateinsulation
of the flush-mounted socket, if necessary.
If the controlpanel is mounted into a flush-mountedsocket, edges of themount-
ing plate may remain visible, which depends on the used socket and the way it
is mounted. If necessary, use paint, wall paper, orsimilar means to prepare the
installation surface.
It also possible to hide the visible edges of the mounting plate by using a wall-
lamp socket with a vertical mounting dimension (screw clearance) of 60 mm.
When tightening the fixing screws the mounting plate must belevel, flush-fitting
and is not deformed by tightening the screws.
