Electrical installation
ECO 275 is equipped for the external connection of 230
volt power plug, internet, display, BMS connection and
Genvex accessories.
See wiring diagrams and operating instructions for the
Optima 270 for more information.
In general, all electrical connections to the ECO 275 must
be made by an authorised professional.
Important!!
For functional and safety reasons, the unit must be con-
nected to a socket with grounding matched to the plug
connection.
Control and calibration of the system
To achieve optimal operation of the system, it must be
calibrated using specialist ventilation measuring equip-
ment. If it is desired to put the system into operation
before calibration, the following approach can be taken:
Before putting the system into operation
1. Check that the Genvex unit is correctly mounted and that
all the ducts are properly insulated.
2. Check that the door can be opened so that it is possible
to service and maintain the unit.
3. Check that the filters are clean (they may be dirty after
installation).
4. Set all supply air valves so that the valve closest to the
unit is opened 3 turns from the closed position and the
outer one 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.
The system can now be put into operation and run until the
system is calibrated using specialist ventilation measuring
equipment.
Optimal initial calibration of the system
Genvex recommends that the ventilation unit should be
calibrated by an authorised Genvex dealer before it is put
into operation.
Before starting the initial calibration, check that the 4
points in the section on control and calibration of the
system have been performed. Then start the unit:
Set the initial basic ventilation value, which is speed 2. To
reduce energy consumption as much as possible, first
adjust the main air flows to the desired air flow by adjusting
the speed of the fans via the control panel.
Then adjust the supply air and exhaust air valves with air
measuring equipment (during the initial calibration of the
valves, remember to lock them and to turn the baffle plate
in the supply air valves so that the air blows in the right
direction).
Check the main air volumes again and fine-tune the main air
volumes using the outdoor air and exhaust air valves (being
sure to lock the position of the valves after the initial
adjustment).
