III GENERAL OPERATION

III.1. GENERAL

VORT NRG ECR
The
efficiency and high performance, designed for service sector and industrial installations. Performance exceeds 80%.
VORT NRG ECR (BASIC VERSION): Fan management by potentiometer and wheel management by thermostats.
Cannot be used with coils.
VORT NRG ECR FIRST: Econological management of fans and the wheel. Allows management of a non-integrated
changeover coil (or a hot water coil and/or a non-integrated cooling coil) or non-integrated electrical heater battery.
VORT NRG ECR PREMIUM BC: Econological management of fans and the wheel. Controls an integral heating coil and
allows management of an non-integrated cooling coil.
VORT NRG ECR PREMIUM BE: Econological management of fans and the wheel. Integral electrical heater battery and
provision for the addition of an extra non-integrated cold water coil.

III.2. OPERATING SEQUENCE

Except BASIC VERSION
Start-up sequence:
• The recovery fan or VAR pressure monitoring mode starts at the same moment the fresh air damper is operated.
• The blower fan or VAR pressure monitoring mode starts at the same moment the recovery air damper is operated.
• Temperature control starts in accordance with the configured control mode. Electrical heating (if configured) starts on
the flow controller only (flow reversal). Pumps that have not yet been activated will start up.
• The alarm management function is activated after the pre-set time period. At this point the system is operating
innormal mode.
Conditions for startup:
The system starts up when one of the following conditions is met:
• The programmed schedule (timer) for normal speed or low speed operation is on "Run".
• The system is started manually from the CORRIGO controller.
• One of the digital inputs for forced run is activated.
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 ECR (BASIC VERSION):

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).
range consists of a programme of dual-flow systems with self-regulating energy recovery, with high
