7 - START-UP
Depending on the ducting pressure drops are available
three configurations that can be set by the ambient
thermostat through the parameter modification.
The setting must be performed both for the exhaust fan
and for the supply fan.
See section 8.3
Fan parameters
EXHAUST
P01
= 1 Low pressure drop
~ 40 Pa
= 2 Medium pressure drop
~ 80 Pa
= 3 High pressure drop
~ 120 Pa
SUPPLY
P08
= 1 Low pressure drop
~ 40 Pa
= 2 Medium pressure drop
~ 80 Pa
= 3 High pressure drop
~ 120 Pa
7.2 FAN CONFIGURATION - AIRFLOW 2020
After the fan configuration in function of the installation
pressure drop it is necessary to check the air flows.
•
Hold the On-Off button (
I
) for 5 seconds until the
unit start-up.
•
On the display is indicated the ambient setpoint.
•
Hold the ventilation button(
C
), the unit is started-
up in the ventilation only mode, check that the air
flows correspond to the nominal ones of the unit
(see the Technical Information section)
•
If necessary, change the outlet and exhaust fan
parameters as described above.
•
Hold the Ventilation button (
C
) to exit from the
Ventilation only mode
7.3 CHECK OF THE AIR FLOW AIRFLOW 2020

I
On - Off
On your keyboard:
P01 = SetUpFanRip = p232
P08 = SetUpFanMan = p233
Identifying the operating objective conditions is useful
to control the unit over time.
With unit at steady state, i.e. in stable and close-to-
work conditions, identify the following data :
•
Total voltages and absorptions with unit at full load
•
Absorptions of the different electric loads
(compressors, fans, pumps etc)
•
Temperatures and air flow of the different fluids
(water, air) both in input and in output from the unit
•
The measurements must be kept and made availa-
ble during maintenance interventions.
