Analog out settings via modbus
Analog out is always active but you need to specify what kind of data you want to read on the
two ports;
1. Configure registers 4×401 and 4×431 for the variables you want to read on the analog out
terminals (0 = Flow, 1 = Temperature, 2 = Damper position).
2. Configure registers 4×400 and 4×430 for analog out level configuration ( (0) 0-10V, (1) 10-0V,
(2) 2-10V, (3) 10-2V)
3. Configure registers 4×401–409 and 4×431–439 with relevant data for max and min levels
for the voltage range selected in step 2. You only need to configure the max and min values
corresponding to the variable selected in step 1.

Default values for the relevant registers related to “Analog Out 2” are according to the table below (Default values for flow
max corresponds to 7 m/s).
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!
*) 0% means fully closed damper position and 100% means fully open damper position.
