MOUNTING
The fan is designed for horizontal or vertical installation on the floor, on the wall or on the ceiling (Fig. 1). The fan can be installed independently or as part of a set with parallel or in-series connection (Fig. 2).
To be installed on the intake spigot side:
• 1 m long air duct in case of horizontal fan installation
• ventilation hood in case of vertical fan installation
The exhaust spigot must always be connected to the air duct.
The fan mounting steps are shown in Fig. 3–10 and 13-18.
The wiring diagrams are shown in Fig. 11-12.

CONTROL LOGIC
The
TT XXX T
fan starts running after the external switch supplies control signal to the LT input terminal (for example, during turning the light on).
After removal of the control signal the fan continues to run within the set time (adjustable with the turn-off delay timer from 2 to 30 minutes).
To adjust the fan turn-off delay time, rotate the control knob T clockwise to increase and counter-clockwise to decrease the turn-off delay time respectively (Fig. 19).
Warning!
The timer circuit is under mains voltage. Disconnect the fan from power supply prior to any adjustment operations. The fan delivery set includes a specially designed plastic screwdriver for adjustment of the fan parameters. Use exclusively the delivered plastic screwdriver to adjust the turn-off delay time. Do not use a metal screwdriver, knife, etc. for adjustment operations not to damage the circuit board.
The
TT XXX U/U1/U2(n)
fan is equipped with an electronic TSC control unit (speed controller with electronic thermostat) for automatic speed control (air flow control) depending on the air temperature (Fig. 21).
The terminal box cover incorporates 2 control knobs:
• for setting the fan speed;
• for setting the thermostat set point.
The thermostat LED light is located on the fan casing.
The thermostat LED glows as air temperature exceeds the set point.
To set the thermostat set point rotate the temperature 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.
11
EN
The fan functioning logic may be based on temperature or timer controls:
TT XXX U(n):
the fan switches to the maximum speed as the room air temperature exceeds the set point.
As the air temperature drops down 2 °C below the temperature set point or if the initial temperature is below the set point, the fan operates with the set speed.
TT XXX U1(n):
the fan switches to the maximum speed as the room air temperature exceeds the set point.
As the room air temperature drops down below the temperature set point, the timer starts 5 minutes countdown and then the fan switches to the set speed.
TT XXX U2(n):
As the indoor air temperature exceeds the set point, the fan switches to the maximum speed.
As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the fan is turned off.
The
TT XXX P
fan is equipped with a speed controller that enables switching the fan on/off, smooth speed (air flow) control from minimum to maximum value (Fig. 22).

MAINTENANCE
Clean the fan surfaces of dirt and dust each 6 months (Fig. 23–29).
Disconnect the fan from power supply prior to any maintenance operations.
For cleaning the fan use a soft cloth or a brush wetted in a mild detergent solution.
Avoid water dripping on the electric components (Fig. 28)!
Wipe the fan surfaces dry after cleaning.
