Start-up, adjustments, use, commissioning and unit in hipernation |
33
Switch on power and the unit should be ready for the start-up.
For start-up see the Operator’s guide for the Systemair control panel - Annex 17 (this manual is delivered with the unit
– printed on paper and also available on the delivered DVD).
K.5 Adjustments and use
Adjust the factory set values for parameters on the Systemair Control Panel or via the software E-Tool on a PC. See the
Operator’s guide for the Systemair control panel - Annex 17 (this manual is delivered with the unit – printed on paper
and also available on the delivered DVD. Further information about the controller is available in the Corrigo E28 User
Manual that is available on the delivered DVD.
E-Tool software is also available on the delivered DVD and for download from a homepage.
K.6 Description of functions
K.6.1 Remote control
K.6.1.1 Communication to BMS systems with MODBUS
The controller has been prepared for communication via RS485 communication port to a MODBUS based BMS system
(Building Management System).
The controller can work as a stand-alone system without any support from other controllers.
K.6.1.2 Communication to BMS systems with LON
The controller has been prepared for communication via LON communication port to BMS systems (Building Manage-
ment Systems).The port uses LonWorks according to the LonMark-guidelines. The LON-interface variables are available
from Systemair. The controller can work as a stand-alone system without any support from other controllers.
K.6.1.3 Communication to BMS systems via BACnet
The controller has been prepared for BACnet TCP/IP interface. This can be used for communication with a BMS system
(Building Management System).
The controller can work as a stand-alone system without any support from other controllers.
K.6.2 Extended operation and external start/stop (for example by presence detectors)
When the unit is running at reduced speed or is in shutdown mode, it can be forced up one step by using a Push button
(impulse). The required number of minutes for the extended operation must be selected on the Systemair Control Panel.
Button and cable are not delivered by Systemair. Furthermore when the unit is in shutdown mode it is possible to start/
stop the unit by presence detectors. Presence detectors and cable are not delivered by Systemair.
K.6.3 Valve and valve motor for heating coil
The supply voltage for the water valve actuator is 24V AC, the control signal is 0-10 V. The sensor for water tempera-
ture has to be installed in the heating coil and the sensor is provided with cable but not connected to the terminals in
the cabinet. The cable between valve motor and terminals in the cabinet is not delivered by Systemair. Standard valves
are available for 2 or 3-way connection.
K.6.4 Valve and valve motor for cooling coil
The supply voltage for the water valve actuator is 24V AC, the control signal is 0-10 V. Cables between valve motor
and terminals in the cabinet are not delivered by Systemair. Standard valves are available for 2 or 3-way connection.
K.6.5 DX cooling
A DX-cooler can be connected to the controller. Input and output are available for:
Start cooling – Alarm cooling – Cooling Y3. Cables are not delivered by Systemair
K.6.6 Circulation pump, heating
Circulation pump is not included in the delivery from Systemair. If the pump has not been activated for 24 hours, the
pump is exercised once daily for 1 minute to keep the pump in a good condition. Cables are not delivered by Systemair.
