OPERATION ALGORITHM
The motor is controlled by sending of an external control signal from 0 to 10 V to the X2 terminal block or by
the R1 internal speed controller. Control method selection is carried out by means of the SW DIP switch:
- DIP switch in IN position. The control signal is set by the R1 internal speed controller, which allows to turn the
fan on and off, smoothly adjust the speed of the fan motor (air flow) in the range from minimum to maximum
speed.
Rotations are controlled from minimum (extreme right position) to maximum (extreme left position). When
rotating clockwise, the rotations decrease.
- DIP switch in EXT position. The control signal is set by the S1 external control unit.
The
TT PRO EC U (Un)
fan is equipped with an electronic module
TSC
(speed controller with an electronic
thermostat) for automatic fan speed control (air flow) depending on the air temperature.
The terminal compartment incorporates 2 control knobs:
• presetting speed
• setting electric thermostat threshold value
The thermostat operation indicator is located on the fan cover.
To set the thermostat threshold, rotate the thermostat control knob clockwise to increase or counter-clockwise
to decrease the temperature set point.
To set the fan speed (air flow), rotate the speed control knob in the same way.
CAUTION!
In case of short-term effects of electrostatic disturbance on the
TT PRO EC U (Un)
fan, the fan may
stop. To restore it, turn the fan off and on with the speed controller, which is located on the fan casing.
