25EcoBreeze System Operation and Maintenance
• DP Sensor Sel:
– None: No differential pressure (DP) measurements are to be supplied to the unit.
– 4-20 mA, 0-10 VDC: A user supplied DP sensor of the selected type has been
connected to the remote interface panel.
– BMS: DP measurements are to be input via the Modbus interface.
– AFC: DP measurements are to be controlled by the AFC.
• DP Filter Coef: 0.0 - 1.0 - This parameter is a filtering coefficient for the DP sensor. The
larger the value of this parameter, the more weight is given to previous sensor readings.
If sensor readings fluctuate excessively, increase the value. If the sensor is not
responding quickly enough to changes, reduce the value.
• DP Sensor Min: -2491.0 - 2491.0 Pa - When DP Sensor Sel is set to 4-20 mA or 0-10
VDC, this property specifies the minimum value that the sensor will generate. For
example, if the sensor is a 4-20mA device, this value represents the differential pressure
that the device will report at 4mA.
• DP Sensor Max: -2491.0 - 2491.0 Pa - When DP Sensor Sel is set to 4-20 mA or 0-10
VDC, this property specifies the maximum value that the sensor will generate. For
example, if the sensor is a 4-20 mA device, this value represents the differential pressure
that the device will report at 20 mA.
The IT Fan Mode setting will be in the highlighted box on the screen. Use the
DOWN key to
move the highlight box to your selection and press
ENTER to select it. Press ENTER to cause the
box to flash. Then press the
UP or DOWN keys to change the setting. Press ENTER to save your
change. Press
ESC to return to the option selection screen.
Water Setup. (Requires admin password)
• Pump Rot Intvl: (0 (never switch) - 15 days) - This property is the amount of run time that
the lead water pump will be allowed to accumulate before switching to the lag pump.
• Water Saver: Off/On
• Dry Op Delay: 24 Hrs - If the water system has not operated for the time specified by this
property, the basin will be drained.
The Pump Rotation Interval setting will be in the highlighted box on the screen. Use the Down
arrow to move the highlight box to your selection and press
ENTER to select it. Press ENTER to
cause the box to flash. Then press the arrow buttons to change the setting. Press
ENTER to
save your change. Press
ESC to return to the previous screen.
