Shutdown sequence :
The system shutdown procedure is as follows :
• Deactivation of the alarm management function.
• Deactivation of electrical heating (if configured).
• After a certain time interval (individually pre-set for each fan), the fans are switched off.
• The fresh air and return air dampers are closed.
• The signals sent to the actuators are re-set to zero and the pumps are stopped.
Conditions for shutdown :
The system shuts down when one of the following conditions is met :
• The programmed schedule (timer) for normal speed or low speed operation is on “Stop” and the forced run signal is
also on “Stop”.
• Activation of the external shutdown command.
• The system is shut down manually from the CORRIGO controller.
• Intervention of an alarm configured with the supplementary shutdown function. The system will restart automatically
once the alarm has been reset.
III.3 CONTROL MODES
III.3.a.
VORT NRG EC
1 speed that can be controlled by potentiometer
Each fan can be controlled individually by a potentiometer integrated in the system.
Possibility to add a remote forced shutdown control connected in series to the contactor (not supplied).
III.3.b. ECO :
1 or 2 speeds that can be controlled via the display/remote control/external control “VENTIL. MODE (%)”
Setting of a minimum speed (LS - 1/2) and a maximum speed (HS - 1/1 as %.
Equipped with factory-set timer :
• (HS - 1/1) from 06:00 to 22:00
• (LS - 1/2) from 22:00 to 06:00
Possibility to add a remote forced run control (LS - 1/2) or (HS - 1/1)
Possibility to add a remote forced shutdown control
III.3.c. DIVA
Proportional ventilation between two flow rates (HS/LS) with “AUTOMATIC CO2 CONTROL MODE”.
Setting of a minimum speed (LS - 1/2) and a maximum speed (HS - 1/1) as %.
The CO2 setpoint is factory-set to 1000 ppm (in accordance with RT2012).
The transition between (LS - 1/2) and (HS - 1/1) is controlled in accordance with the CO2
level.
Equipped with continuous run factory-set timer (LS - 1/2).
Possibility to add a remote forced run control (LS - 1/2) or (HS - 1/1) (NO volt-free contacts)
Possibility to add a remote forced shutdown control (NO volt-free contacts)
Note : In order for the CO2 control to function correctly, the system must meet the following conditions :
•
Timer (HS - 1/1) on 0 (inactive) (Normal speed timer)
•
Timer (LS - 1/2) in operation (Low speed timer)
•
Forced run (HS - 1/1) and Forced shutdown not activated.
III.3.d. LOBBY
®
Constant ventilation pressure. (Pa) “CONSTANT Pa MODE”
Setting a constant pressure (Pa).
Equipped with continuous running factory-set timer (LS - 1/2);
Possibility to add a remote forced run control (LS - 1/2)
Possibility to add a remote forced shutdown control
