2.47.2 Fan type
Address : D1A5 - D1AA
Write authorization : ebm-papst
Coding:
The fan type is stored here in ASCII characters
D1A5 contains the first two characters of this.
D1AA contains the last two characters.
2.48 Air flow reference value
Address : D1ED
Write authorization : ebm-papst
The relative coded values for air flow are based on this reference value, i.e. for volume flow control the set
value (holding register D001) and the actual value (input register D035).
Coding:
2.49 Mass flow reference value
Address : D1EE
Write authorization : ebm-papst
The relative coded values for mass flow are based on this reference value, i.e. for mass flow control the set
value (holding register D001) and the actual value (input register D036).
Coding:
