Control and adjustment of the system
To achieve optimal operation of the system, it must be
adjusted
using specialist ventilation measuring equipment. If you
wish to put the system into operation before adjusting it,
you can do the following:
Before putting the system into operation
1. Check that the Genvex unit is correctly installed and
that all the ducts are properly insulated.
2. Check that the base plate can be opened so that it is
possible to service and maintain the unit.
3. Check that the filters are clean (may be dirty after
installation).
4. Check that the condensate drain is correctly installed
with a water trap and protected against frost. Pour 1
litre of water into the condensate tray and check that it
runs through the condensate drain unhindered.
5. Set all supply valves such that the valve closest to the
unit is opened 3 turns from the closed position and the
outer valve is opened 8 turns from the closed position.
The intermediate valves are opened between 4 and 7
turns, depending on how close they are to the unit.
6. If a reheating surface is installed in the system, the
supply air temperature is set to 0–3°C below the room
temperature in the home.
The system can now be put into operation and run until the
system
is adjusted using specialist ventilation measuring equip-
ment.
Electrical installation
The electrical connection must be executed by an authori-
sed electrician. See wiring diagrams.
“Important: for safety reasons, the machine must be con-
nected to a socket with grounding adapted to the plug con-
nection”
Access to the control board is obtained by removing the
safety screw as shown in the picture. See picture 1.
The Optima 270 control board can then be pulled down via
the integrated rail system, and the terminals are now freely
accessible for connecting additional equipment. See pic-
ture 2.
A display (accessory) is connected to the socket marked
with “display” on the outside of the cabinet.
A CTS system is connected to the Modbus connection
marked “BMS/CTS”.
Fire/district heating/CO2 sensors are connected to the
Modbus connection marked “I/O”.
An internet/router is connected to the RJ45 connection
outside the cabinet.
Also see “Operating instructions, Optima 270” for further
details.
