Exhaust fan MIN day
Set the
minimum airflow
of the
exhaust
fan
during the
“day”
period. This set fan
speed will never* be undercut. Please find
additional information in chapter 8.
*during pressure, sensor calibration is in process,
all fans are turned off.
The minimum fan speed is 10%.
Additionally, “OFF” can be selected. This
means that the intake fan will be switched
off as long as the measured temperature is
below the desired temperature.
Ensure that the fan is still rotating at the set
minimum fan speed and the airflow is
sufficient for cooling the motor.
2.7
Intake fan MAX day
Set the maximum fan speed of the intake
fan during the day period. The specified
value will never be exceeded.
2.8
Intake fan turnoff day
Set the
minimum fan speed
of the intake
fan for a standard duct fan during the
day
period
. If this value is undercut in the
controller’s operation, the intake fan will be
switched off to maintain the negative
pressure inside the grow room. The
minimal possible fan speed is 10%.
Additionally, “OFF” can be selected,
whereby the fresh air fan will always be
disabled during the daytime.
This value is only relevant for standard duct
fans. EC fans always turn off at 10%.
Ensure that the fan is still rotating at the set
minimum fan speed and the airflow is
sufficient for cooling the motor.
