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 25-30.

The wiring diagrams are shown in Fig. 11-24.

CONTROL LOGIC

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. 31).

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) 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. 33).

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.
