CM_P - Manual humidity calibration

1) Switch unit ON
2) On operator PCB set DIP switch 2 to „ON" position
3) Select calibration with timer dial:
4) Activate manual calibration by pressing core temperature key
5) To de-activate function test set DIP switch 2 to „OFF"
position. Switch unit off and on again.
Duration for calibration is 45 min for unit size 61-102 and 60 min for unit size 201-202.
This basic information is evaluated during „self test" after installation or during manual calibration and stored on
the PCB and EEPROM.
Manual calibration has to be done when any of the below listed service work has been carried out:
1 changing PCB
2 removing of fan wheel / motor
3 changing thermocouple B4
4 changing differential pressure sensor P1
5 changing air baffle
6 installation of a UltraVent or extraction hood on top of the unit
7 installation as the lower unit of a Combi Duo after it has done a self test as a single unit
Note: In this case do NOT run a new self test, as otherwise the boiling point and the gas blower speed
will be overwritten!
