2.1.6 Changing the relative humidity setpoint
If a sensor for relative humidity is connected to the PROBA110 , the user can
change the setpoint of the humidity control.
Make sure that the key switch is in the PE position.
Press the HUM/GAS key.
The lower display shows the text 'RH', indicating that the RH setpoint can be
changed.
The upper display shows the present RH setpoint.
The value can be changed with the UP and DOWN keys.
After the setpoint is changed, press the HUM/GAS key to return to the
normal operation mode.
Rotate the key switch to ON . Remove the key to prevent unauthorized use.
Please note:
While the PROBA110 is executing a ripening program or is in the STANDBY
mode, this is the time to change the setpoint. The new setpoint will remain
active until the
PROBA110 is switched off or the setpoint is changed again.
