Basic Setup - Swegon ESENSA Series Manual

2.1.3 Basic setup

When the air handling unit is started up for the first time, the
commissioning menu is automatically displayed. At the very end
of the commissioning (menu) the commissioning of the unit has
to be confirmed by the service technician. Once the commis-
sioning has been confirmed, the commissioning menu will not
be displayed as first menu any more. The commissioning menu,
however, will remain accessible through the advanced setup. See
Section 2.1.4.

Airflow regulation
The desired control mode can be set here. The setting can be
changed at any time in the basic setup menu. Depending on
the selected function, flows can be set as (l/s, m³/h), pressure
(Pa), input signal strength (%) or torque (%). For both "Airflow
control" and "Torque control", three setpoints are available: Low,
medium and high.

Constant airflow
Flow control involves operating the air handling unit to
keep the preset airflow constant. The speed of the fans is
automatically regulated to provide correct airflow even if
the filters become clogged, diffusers are blocked, etc. The
exhaust air fan is controlled as a slave. A ratio between
exhaust and supply pressure can be configured in order
to create over, under or balanced pressure. For units with
backward fans, constant airflow can only be selected if
the "constant air kit" has been ordered as an option. The
desired setpoint is preset in (l/s, m³/h).

Torque control
3 torque setpoints to be configured by the user (%TQ K1,

maximal torque. The exhaust air fan is controlled as a
slave. A ratio between exhaust and supply pressure can
be configured in order to create over, under or balanced
pressure. The desired setpoint is preset in %. The Torque
control mode can be deactivated in the advanced setup.

Demand control
The airflow desired is regulated in response to 0-10 V
input signals from an external sensor, such as a carbon
dioxide or a humidity sensor. The function can be config-
ured with a positive or a negative logic. A ratio between
exhaust and supply pressure can be configured in order
to create over, under or balanced pressure. The desired
setpoint is preset in (l/s, m³/h). The "sleep factor" is a
lower operating rate for the unit (due to e.g. low occu-
pancy) that will be activated by speed "III "

Constant pressure
The airflow automatically varies to provide constant pres-
sure in the ducting. The duct pressure is measured by an
external in-duct pressure sensor which is connected to
the control unit's BUS communication or the an ana-
logue 0...10V input. The function can be configured on
supply air, extract air or supply and extract air. The first
two configurations will have the second set of fans be
controlled as a slave. A ratio between exhaust and supply
pressure can be configured in order to create over, under
or balanced pressure. The initialisation will allow for an
automatic calculated pressure setpoint, determined by
the nominal airflow. The "sleep factor" is a lower operat-
ing rate for the unit (due to e.g. low occupancy) that will
be activated by speed "III "
