Economy mode ➜ "Supply-air duct pressure" and/or "Extract-air duct
pressure"
The menus "Supply-air duct pressure" or "Extract-air duct pressure" appear in
combination with the menu "Plant/fan" and are only shown whenever a fan speed
setting was selected with duct pressure (see the
"Fan submenu" on page 71 in
Chapter 7.21.6 Air handling unit submenu). If no extract-air or supply-air fan is
available or if a slave control from the setting of a factor or offset was selected,
only one of the two menus appears.
The setting of the supply-air and/or extract-air duct pressure is shown absolutely
in Pascal. In order to avoid faulty entries, the minimum and maximum adjustable
setpoint can be changed with the MATRIX.PC service tool.
Economy mode ➜ "Supply-air volume flow" and/or "Extract air volume
flow"
The menus "Supply-air volume flow" or "extract-air volume flow" appear in com-
bination with the menu "Plant/fan" and are only shown whenever a fan speed set-
ting was selected with volume flow control (see the "Fan submenu" on page 71 in
chapter 7.21.6 Air handling unit submenu). If no extract-air or supply-air fan is
available or if a slave control from the setting of a factor or offset was selected,
only one of the two menus appears.
NOTICE!
The speed setting can be influenced by the minimum and maximum permissi-
ble speed saved in the controller or the frequency converter. The values in the
controller can be changed with the help of the MATRIX.PC service soft-
ware.The values of the frequency converter can be changed using the control
panel of the power inverter.
Supply-air duct pressure
65
Extract-air duct pressure
72
Value range: 0 to 5,000 Pa (factory setting)
Adjustable steps: 1 Pa
Factory setting: 0 Pa
NOTICE!
The measuring range of the pressure sensor(s) is configured (e.g. 0-
500 Pa) during commissioning using the MATRIX.PC service tool or
the control panel (see Chapter "Sensor inputs range start/range end"
on Page 78). If this range is smaller than the adjustment range con-
figured for the control panel, then the measuring range of the pres-
sure sensor is automatically taken over as the adjustment range.
