K.6.7 Fire alarm function
K.6.7.1 External fire signal that indicate block or run
The unit is available without components for this function. The controller is as standard configured for ordinary running
when the contact is closed (NC). By open contacts the fans stop and the dampers close. If disconnected, fire is indicated
and the unit will stop until the signal is re-connected. On the site qualified technicians are able to change the
configuration.
K.6.7.2 External fire signal
The unit is delivered without components for this function. The controller is as standard configured for ordinary running
when the contact is closed (NC). By open contacts the fans stop and the dampers close. When the unit has been shut
down by a fire signal, the unit has to be restarted on the control panel. On the site qualified technicians are able to
change the configuration.
K.6.7.3 Two fire thermostats
The unit is available with 2 thermostats installed in the unit – 1 in the extract air and 1 in the supply air. The cut-off tem-
perature in the thermostats is adjustable between 40 and 70˚C. At the factory supply is set at 70˚C and extract is set at
40˚C. The controller is as standard configured to stop the fans and close the dampers if a thermostat is released. On the
site qualified technicians are able to change the configuration.
K.6.7.4 One smoke detector in extract air
The smoke detector has been installed in extract air next to the fan. The controller is as standard configured to stop the
fans and close the dampers if the detector is released by smoke. When the unit has been shut down by a fire signal, the
unit has to be restarted on the control panel. On the site qualified technicians are able to change the configuration.
K.6.8 E tool - configuration tool
The installer can download the PC software called E tool from www.regincontrols.com and this software enables the in-
staller to configure and supervise the function of the system via a graphic interface. This software displays all the pa-
rameters to be written in a commissioning report (the commissioning report is available as a Word-file on the DVD
delivered with the unit). The TCP/IP port in the Corrigo E28 controller is prepared for communication with the E tool
software.
K.6.9 Electrical heater battery
K.6.9.1 Control of heating capacity connected to unit with Systemair control system
Electrical heater installed with separate controller beside the heater. The separate controller is designed for capacity
conversion of the 0-10 V control signal from the main control system. The electric heater is not supplied from the air
handling unit cabinet as the cabinet is not designed to supply the heater with power. No power supply cables are con-
nected to the electric heater. The separate controller is without supply disconnecting device.
K.6.9.2 Control of heating capacity connected to unit without Systemair control system
Electrical heater installed with separate controller beside the heater. The separate controller is designed for capacity
conversion of the 0-10 V control signal from the main control system. The heating capacity is adapted in steps.
The electric heater is not supplied from the air handling unit cabinet as the cabinet is not designed to supply the heater
with power. No power supply cables are connected to the electric heater. The separate controller is without supply dis-
connecting device.
K.6.10 Speed control of fans
K.6.10.1 Control system - frequency converters inside the unit are IP 20
Fan motor revolutions are controlled by frequency converters, and 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 ca-
bles between motor and converter. In units with complete control system the frequency converters are delivered with
system parameters adapted to the motors and the project.
K.6.10.2 Pressure transmitters
Separate control of the air flow or duct pressure for supply fan and for extract fan. The required air flow or duct pres-
sures with normal as well as reduced capacity are selected on the Systemair Control Panel. The actual pressure is
