Zero Pressure Calibration - Siemens Climatix S300 HRV Application Manual

Remark:

6.2.6 Zero pressure calibration

Parameter
Zero pressure calibration trigger POS9
Zero pressure calibration trigger QBM #1
Zero pressure calibration trigger QBM #2
A6V10733786_en_c
Above information is available for all ebm-papst Modbus fans with interface version
>= 5.0.
Error and warning codes are shown as decimal value, for example error code '17'.
They must be converted into a bit string, for example '0000 0000 0001 0001'.
According to EBM Papst documentation, this means FB (General fan fault) and
PHA (Phase error).
When using a Modbus fan, both fans must be Modbus fans.
● Both devices (POS9.., QBM97..) have integrated pressure sensors and
therefore also inbuilt zero-pressure-calibration mechanisms.
● To perform calibration, all pressure hoses must be disconnected and exposed
to the same ambient pressure.
● The calibration process can be manually initiated by activating the calibration
parameter.
