7. FAN SPEED CONTROL
Fan with EC motors speed is controlled with 0-10VDC signal input. Additional accessories (speed controllers) are used for users to control the
desired fan speed from 0 to 100%.
VKA EKO units are integrated with fan speed control potentiometer inside of the connection box to set the desired speed.
VSVI EKO AL CPG units are integrated with UNIcon CPG-..AV sensor-control modules. These modules control fan speed by desired air pressure
or flow. By default, air pressure tubes are connected for fan speed control by air flow. To prepare the unit to control fan speed by air pressure, tubes
must be connected as shown in the VSVI EKO AL CPG diagram on section "PIPING AND INSTRUMENTATION DIAGRAM".
More information about fan control, control module configuration and preparation can be found in "UNICON CPG-..AV OPERATING INSTRUC-
TIONS" (L-BAL-E253).
Fan with AC motors speed is controlled with supply voltage or frequency (depending on the fan unit model).
