The GEA Cassette Gekos each have 2 air distribution openings in the                                                                       However, note that the number of air outlets used will

These make it possible to install ducts by others (e.g. DN150 flexible                                                                    Refer to the graphs below for the resulting air volume

In this case, the unit's own air vanes can remain opened or be closed.
                                                                                                                                          The graphs apply to the maximum speed of the units.

 Alternatively to a return air sensor, a room temperature sensor can be connected to a CET type switch.
 If a return air sensor is used, the fan must be operating in a continuous mode.

 Please note:
 In connection with thermostat and speed switches only 2-point valve actuators (T) can be
 used.

GEA Cassette-Geko                                                                    Controls System GEA MATRIX®
                                                                                                    Installing Control Panels


                                                 As the control panel is split into two units, the the control panel cover only
                                                 needs to be snapped on the mounting plate during commissioning. This
                                                 provides optimum protection against dirt and damage for the control panels
                                                 during the construction phase.




                                                 The cable connection is made via cage clamps. This enables quick and easy
                                                 use of solid and flexible cores.




                                                 To mount the control panel over a standard in-wall socket, corresponding drill
                                                 holes need to be provided in the mounting plate.




                                                 The control panel can also be fitted directly onto the wall (cable laid under
                                                 plaster or in cavity wall).




                                                 IP54 control panels for moisture proof applications are available on request.




                                                 To prevent dirt accumulation or accidental operation, control panel covers
                                                 are available as accessories (See Fig. 54 page 50).

GEA Cassette-Geko                                                                           Control System GEA MATRIX®


                                               MATRIX.OP71 control panel for all groups
                                               The MATRIX.OP71 control panel is designed to be operated from one central point. It
                                               can integrated at any location within the MATRIX network and can simultaneously
                                               serve up to 16 groups.
                                               Up to 16 unit groups can be assigned to one cluster:
                                               – One unit group per each cluster
                                               – Each cluster with up to 16 unit groups.
                                               Clear text menus and "push&turn" function enable easy handling during operation or
                                               configuration. A maximum of 16 unit groups can be induvidually grouped to clusters.
                                               Using the control panel the wanted setpoints for temperature, fan speed, etc. can be
                                               assigned for each cluster. Thanks to the control unit features comprising all groups, the
                                               necessary room or return air sensors are located in the respective groups (group
                                               locations).
                                               Local control panels (OP2xx, OP3xx, OP4xx, OP5x) can be additionally integrated in
                                               individual groups. Their functional scope can be defined and adjusted using the control
                                               panel for all groups. Thus, a relative daily setpoint can be entered via a local control
                                               panel, whereas the OP71C setpoint is assigned as standard.
                                               The integrated clock timer enables to assign 8 weekly programmes to clusters at any
                                               sequence. Each weekly programme enables to enter four switching times per day
                                               (2 x On/2 x Off), that can also be set to be valid for the whole day. Besides, it is possible
                                               to set 8 special switching days with up to four switching times (2 x On/2 x Off) per
                                               special switching day. Holidays / bank holidays can be set using the calendar annual
                                               programme.
                                               During holidays the unit can be set to operate in "unit off" or economy mode.
                                               The summer / winter time switch over is performed automatically.
                                               The control unit is currently supplied with 7 selectable languages:
                                               – German
                                               – English
                                               – French
                                               – Polish
