H.4 Description of functions
H.4.1 Remote control
H.4.1.1 Communication to BMS systems via BACnet
If Systemair has supplied the controls for the Geniox unit, network communication using BACNet communication protocol is available.
Depending on the controls that have been provided, either BACNet/IP or BACNet MS/TP is available for communication with a BMS
system (Building Management System).
The ECB series of controllers are BTL listed as an Advanced Application Controller (B-AAC) guaranteeing interoperability with other
manufacturers of BTL listed devices. The controller communicates using the industry standard BACnet MS/TP protocol allowing ease of
installation into a new controls network or an existing one.
The ECY series of controllers are listed as a BACNet Building Controller (B-BC). It supports multi-protocol communications including
native BACNet/IP and optional BACNet MS/TP
The controller can also work as a stand-alone system without any support from other controllers.
H.4.2 Occupied/Unoccupied override
With Systemair controls, the Geniox unit can be overridden into occupied mode for testing and commissioning purposes. It can also
locally be placed into permanent unoccupied mode for extended period of unoccupied status
H.4.3 Valve and valve motor for heating coil
The supply voltage for the water valve actuator is 24 VAC, the control signal is 2-10VDC. Standard valves are available for 2 or 3-way
connections.
H.4.4 Smoke detector in return air
The unit is available with or without components for this function. The smoke detector can be installed in the return air stream. The fans
will be stopped and dampers will be closed if smoke is detected.
H.4.5 Electrical heater
The unit available with SCR electric heat which is modulated by a 0-10VDC signal.
H.4.6 Speed control of fans
H.4.6.1 Control system – frequency converters inside the unit
Fan motor revolutions are controlled by frequency converters for AC Fans. They are configured and tested to comply with the data for
the unit. The frequency converter for each fan motor is installed inside the unit beside the fan motor with cables between the motor
and converter. The frequency drives will be delivered with system parameters adapted to the motors and the project. The frequency
converter will require an enable signal and a 0-10 VDC input signal.
For units with ECM Fans, the fans will require a 24 VDC enable signal. The fan speed will be controlled by an analog 0-10VDC signal.
H.4.7 Pressure transmitters
For units with duct pressure or airflow requirements, separate control for the supply and exhaust fans are required. The required air flow
or duct pressures can be adjusted via settings in the controller when supplied with Systemair unit controls.
H.4.8 Temperature Sensors
With Systemair Controls, temperature sensors are delivered with each unit
• 1 sensor in the return air stream, installed in the unit
• 1 sensor in the outdoor air, installed inside the unit before the supply air filter
• 1 sensor in the supply air stream to be placed in the supply air duct by the installer
• 1 sensor in the exhaust air stream, installed inside the unit
• 1 sensor in the mixed air chamber, where there is a mixed air damper present, installed inside the unit
