1. INSTALLATION OF OPTIMA BASIC
Important information
Safety information
This appliance can be used by children aged 8 and over and
by people with reduced physical, sensory or mental
capabilities or lack of experience and knowledge, as long as
they are supervised or have been instructed in the safe use
of the appliance and understand the hazards involved.
Children must not play with the appliance. Children must
not clean or maintain the appliance without supervision. We
reserve the right to make design or technical changes.
1.1 Installation
Installation of the control panel
The control panel is intended for installation on a flat wall.
1.2 Assembly
Find the place on the wall where you want to attach the
control panel and mark the location of the screw holes.
At least two screws must be used to secure the control
panel to the wall. The type of wall will determine the
method for drilling holes, the hole size and the correct
screws for fixing the panel.
When the control panel is securely mounted on the wall,
take the Optima Basic panel, which comes with a pre-
installed cable, and pass this cable through the opening in
the cabinet, as shown in the picture.
Secure the cable to the chassis with a cable tie as shown to
prevent the cable from being pulled out of the clamp in the
display.
Please note: If the pre-installed 1.8 metre Optima Basic
cable is not long enough, it is possible to replace this with a
4-core 0.25 mm2 twisted pair cable with a length of up to
50 metres.
Attach the control panel to the cabinet using four screws as
shown in the picture.
Complete the installation by carefully snapping the plastic
cover onto the cabinet as shown in the picture.
Please note: The control panel can installed flush with the
wall using an integrated Euronorm box.
To remove the control unit, click off the plastic cover and
remove the screws.
For further information about connecting the control panel
to the Optima 270, refer to the electrical diagram in the
installation manual.

1.1 Installation
Installation of the control panel.
The control panel is intended to be mounted on a flat wall.
1.2 Assembly
Find the place on the wall where you want to attach the
control panel and mark the location of the screw holes. At
least four screws must be used to secure the bracket to the
wall. The type of wall will determine the method for drilling
holes, the hole size and the correct screws for fixing the
panel.
Once the bracket is securely mounted on the wall, take the
Optima Touch display, which comes with a pre-installed
cable, and carefully click the display onto the bracket. Make
sure the cable is carefully routed as shown in the picture
before installing the display.
Please note: If the pre-installed 1.8 metre cable is not long
enough, it is possible to replace this with a 4-core 0.25
mm2 twisted pair cable with a length of up to 50 metres.
To remove the display, gently press the plastic clip (locking
mechanism) as shown in the picture.
For further information about connecting the control panel
to the Optima 270, refer to the electrical diagram in the
installation manual.

2. PROGRAMMING THE OPTIMA 270
CONTROL UNIT
The control system is preset from the factory, which means
that the unit can be put into operation without changing the
operating settings. The factory setting is a basic setting
that can be adapted to the wishes and requirements
applicable to the home in question to ensure optimal
utilisation and operation of the system.
Depending on the product's configuration, it is possible to
connect Optima displays directly to the connector outside
the product (connector labelled "display") or directly on the
printed circuit board.
The I/O interface includes terminals for connecting both
Modbus Master (e.g. BMS/CTS systems) and Modbus Slave
devices (e.g. district heating, fire box PCB or CO2sensors).
To expose the clamps, carefully remove the dust shield
sticker.
2.1 System without display interface
2.1.1. Connect an Optima Touch display to the Optima 270
and adjust the settings as needed. Remove the Optima
Touch control panel when programming is complete. The
Genvex ventilation system will continue to operate
according to the new set parameters.
2.1.2 Use the Genvex PC tool to adjust the Optima 270
parameters. Connect a laptop to the IO interface via the
Optima Basic or Touch display and use the PC as an
interface for programming the Optima 270, or connect it
directly to the micro-USB connector on the Optima 270
circuit board.
Optima Basic and Touch displays can be retrofitted to this
type of installation if required.
2.2 Installation with Optima Basic display
See details under 1.0.
2.3 Installation with Optima Touch display
2.3.1. Connect an Optima Touch controller to the Optima
270 and adjust the settings as needed.
NOTE: The Optima 270 control unit parameters can be
saved on the Optima Touch for one ventilation system and
transferred to a similar system by using "EA1 Save" and
"EA2 load settings" to save and load the settings,
respectively.
The latest version of the Genvex Genlog software can be
ordered from Genvex by calling [phone].
