In case of using the fan for smoke and heat extraction, remove the red bridge 16-17 (fire mode) and connect control-
ler to fire central up to wiring scheme. Warning: removing this bridge without connecting to fire central and run-
ning the fan in fire mode causes no protection is active. Running in fire mode is allowed only in case of fire or during
periodical tests.
For fan speed setting with potentiometer remove bridge 9-10 and connect potentiometer (R >= 1kΩ) according to
wiring scheme.
For fan speed setting using AN1 input (0-10V): remove bridge 9-10 and connect 0-10V input according to wiring
scheme.
Replace bridge 18-19 with start – stop switch.
Controller default setup controls the fan speed with potentiometer or AN1 input.
Using internal regulator for fan speed control requires change of controller setting via MODBUS (see controller instruc-
tions). Using MODBUS for fan speed control requires change of controller setting via MODBUS (see controller instruc-
tions).
Minimum fan speed can be increased in setup via MODBUS. Maximum fan speed can be decreased in setup via
MODBUS.
More about settings please see controller instructions.
Terminals 4 to 23 (lower markings in the
connection box) are led from controller
out to outer connection box.
3 bridges are factory inserted to allow
test of fan without connecting control
cables.
