2 Holding registers
2.1 Overview
The holding registers are stored in the RAM and in the EEPROM of the fan.
The access times (and thus also the response times) differ depending on the area
The following areas are defined:
Address
Area
Typ. time for read access
Typ. time for write access
D000 ... D0FF
RAM
1 μs / holding register
1 μs / holding register
D180 ... D37F
D400 ... D614
EEPROM
160 μs / holding register
12.3 ms / holding register
D380 ... D3FF

The following list provides an overview of all parameters.
In addition to the MODBUS address and the designation, it shows the authorization level required to write a
parameter, as well as the address of the memory location for factory setting and customer setting (if
applicable).
The function of the parameters is described in the following sections
