III GENERAL OPERATION
III.1. GENERAL
The
VORT NRG ECR
range consists of a programme of dual-flow systems with self-regulating energy recovery, with high
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).
