DELIVERY SET

BRIEF DESCRIPTION

The product described herein is a mixed-flow inline fan for supply or exhaust ventilation of premises heated during winter time.
The fan is designed for connection to ø 100, 125, 150, 160, 200, 250, and 315 mm air ducts.
The fan is equipped with an energy-efficient and high-performance electronically commutated motor (EC motor) and with a built-in speed controller.
An external control unit can be connected to the fan (purchased separately).
The fan design is constantly being improved, thus some models may be slightly different from those described in this manual.

OPERATION GUIDELINES

The fan is rated for connection to single-phase AC 220-240 V/50 (60) Hz power mains. The fan is rated for continuous operation.
Air motion direction in the system must match the pointer on the fan casing.
Hazardous parts access and water ingress protection rating is IPX4.
The fan is rated for operation at the ambient temperature ranging from +1 °C up to +40 °C.
The transported air temperature must not exceed +40 °C. Temperature up to +60 ° C is allowed for a short time (up to 15 minutes).
The ventilator is rated as a class II electric appliance.

DESIGNATION KEY

To comply with the ErP 2018 regulation, a local demand controller must be used.

INSTALLATION

The fan is suitable both for horizontal or vertical mounting on the floor, on the wall or on the ceiling (Fig. 1).
While mounting the fan provide extra protection against water ingress, such as:

1. For the top mounting: install an outer protecting hood above (Fig. 2).
2. For any mounting position: connect an air duct on both sides of the fan (Fig. 2).
   The mounting sequence is shown in Fig. 3-8.
   The sequence of connecting the fan to power mains is shown in Fig. 9-11, 13-14.

The fan wiring diagram is shown in Fig. 15.

TERMINAL DESIGNATIONS ON WIRING DIAGRAMS

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 turning the fan on and off, and smoothly adjust the speed of the fan motor (airflow) 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 (airflow) depending on the air temperature.
The terminal compartment incorporates 2 control knobs:
• presetting speed
• setting an 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 (airflow), 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.

MAINTENANCE

Clean the product surfaces regularly (once in 6 months) from dust and dirt (Fig. 18-21). Disconnect the fan from power mains prior to any maintenance operations. To clean the fan, use a soft cloth or a brush wetted in a mild detergent solution. Avoid water ingress to electrical components.
Wipe the unit surfaces dry after cleaning.
