INSTALLATION

The fan is suitable both for horizontal or vertical mounting 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).

Install minimum 1 m long air duct on the intake spigot side in case of horizontal fan mounting or a hood in

case of vertical fan mounting.

The outlet spigot must always be connected to the air duct. The fan mounting sequence is shown in Fig. 4-12

and 25-30. The fan wiring diagrams are shown in Fig. 13-24. Some fan models are equipped with a plastic limit

stop in front of the L1 terminal. Remove the limit stop for connection to the L1 terminal. Obey the restrictions

shown in Fig. 15 and 19.

ELECTRONICS OPERATION ALGORITHM

The TT PRO T fan activates upon control voltage application to an LT input terminal by an external switch

(e.g. indoor light switch). After the control voltage is oﬀ, the fan continues to operate within the set time

period adjustable from 2 to 30 min by the timer. To adjust the fan turn-oﬀ delay time, turn the control knob T

clockwise to increase and counter-clockwise to decrease the turn-oﬀ delay time respectively (Fig. 30).

WARNING!

The timer circuit is live! Disconnect the fan from power supply prior to any adjustment operations. The fan

delivery set includes a specially designed plastic screwdriver for fan settings adjustments. Use it to change

the turn-oﬀ delay time and the humidity set point. Do not use a metal screwdriver, knife, etc. for adjustment

operations not to damage the circuit board.

The TT PRO U (U1) fan (Fig. 32) 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 capacity) rotate the speed control knob in the same way.

The fan operating logic may be based on temperature or timer indications:

Temperature-based operating logic (TT PRO U) is used to keep air temperature to within 2 °C (fan speed

switching will be rare). The fan switches to maximum speed as the temperature reaches the temperature
