Analog communication settings
Analog in settings via modbus
If using analog communication (4×071=1) you need to specify the operational voltage
range and also corresponding max and min values;
1. Configure register 4×500 for analog in level configuration ( (0) 0-10V, (1) 10-0V, (2)
2-10V, (3) 10-2V) if you are using analog control of the set points. (If set points are
controlled via bus this point can be ignored)
2. Configure registers 4×501–504 with relevant data for max and min levels for the
voltage range selected in previous step. Register 4×501–502 are used if the device
is controlled with angle (4×070=1) and registers 4×503–504 are used if the device is
controlled using flow (4×070=2). If set points are controlled via bus this point can be
ignored.

*) 0% means fully closed damper position and 100% means fully open damper position.
PLEASE LOOK IN THE APPENDED MODBUS REGISTER FOR INSTRUCTIONS ON HOW TO CHANGE REGISTER
VALUES. SOME VALUES HAS SCALE FACTORS AND SOME VALUES OCCUPY TWO REGISTERS!
Default values for the relevant registers are according to the table below. (Default values for flow max corresponds to 7 m/s).
