ELECTRONICS OPERATION ALGORITHM
The fan has a built-in speed controller, and a switch on the board to select a control method - by a built-in or an external
controller.
Mode 1: SW switch in IN position. The control signal is set by the R1 potentiometer.
Rotations are controlled from minimum (extreme left position) to maximum (extreme right position).
When rotating clockwise, the rotations increase.
Mode 2: SW switch in EXT position. The control signal is set by the external control device.
The motor is controlled by sending of an external control signal from 0 to 10 V to the X2 terminal block.
The TT Silent-M XXX EC U (n) fan is equipped with an electronic module TSC (speed controller with an electronic thermostat)
for automatic motor speed control (air flow) depending on the air temperature.
The terminal compartment incorporates 2 control knobs:
motor speed preset button
electric thermostat control knob
The LED indicator is placed at the front panel of the fan to show the thermostat operating status.
To set the thermostat threshold, rotate the thermostat control knob clockwise to increase or counter-clockwise to decrease the
temperature set point accordingly.
To set the fan speed (air flow), rotate the speed control knob in the same way.
The TT Silent-M XXX EC P fan is equipped with a speed controller that enables switching the fan on/off and smooth speed (air
flow) regulation from minimum to maximum value.

15
TECHNICAL MAINTENANCE
The fan maintenance periodicity is at least once per 6 months.
Maintenance steps:
Disconnect the fan from power supply and make sure
electricity has been turned off. Disconnect the air duct on
both sides of the fan.
Clean the fan with a soft dry cloth or a brush.
Wipe the fan surfaces dry. Connect an air duct on both sides of the fan. Supply
power to the fan.
CAUTION! Do not allow water or liquid come into contact with electric components!
