2.5.1 EC fan control
The EC fan control function is enabled and the EC fan control configuration settings are shown in
Application tool when the configuration value listed in
Table 2-15 is configured on a controller output.
Figure 2-26 EC fan control configuration settings in Application tool.
The controller outputs a fan speed signal, Y1, that is configured on a controller output by using the value in
Table 2-15 .
In auto mode, the Y1 signal corresponds to the current heating or cooling demand, as illustrated in Figure 2-
27 .
In manual mode, the Y1 signal is independent of the current heating or cooling demand. Instead, the fan
speed 1, 2, and 3 signals are defined by a number of equal thirds relative to the
Limit maximum EC fan speed
to (%) configuration setting, as illustrated in Figure 2-28 . For example, the fan speed 1 signal is equal to 0.33
times the set maximum fan speed value, and the fan speed 2 signal is equal to 0.67 times the set maximum
fan speed value.
