6.2.4 VAV fan voltage settings

The VAV fan settings allow the fan voltage to be controlled, the fan speed will increase

with a voltage increase, and vice versa.

Note:

Different parameters can be set for each fan, the minimum voltage available is 0V and the

maximum is 10V. To set the voltage value for each fan, please refer to the manual of FCU

manufacturer.

For auto wind, there are two options: 3 step and stepless(firmware version:HDL_V03.08U

_2015/01/20). If stepless is selected, the 0-10V output varies continuously according to

the temperature difference between desired temperature and room temperature.
