BRIEF DESCRIPTION

The product described herein is a plastic sound-insulated fan for supply or extract ventilation of premises.
The fan is connected to the ø 100, 125, 150 and 160 mm air ducts.

OPERATION GUIDELINES

The unit is designed for connection to power mains with the parameters specified in the «Technical data» section.
The fan is rated for continuous operation.
Air motion direction in the system must match the pointer on the fan casing.
The Stream unit is rated as a Class II and Stream EC as Class I electrical appliance.
Ingress protection rating against access to hazardous parts and water ingress is IPХ4.
The fan is rated for operation at the ambient temperature ranging from +1 °C up to +40 °C.

DESIGNATION KEY

TECHNICAL DATA

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

MOUNTING

The fan is suitable both for horizontal or vertical mounting on the floor, on the wall or on the ceiling. The fan can be installed independently or as part of a set with parallel or in-series connection.

The diameter of the spigots in the Stream 100/125 model can be changed using adapters, and in the Stream 150/160 model using the rubber seal.
On outlet (discharge) spigot side it is necessary to install:

• in case of horizontal installation – a duct with a length of at least 1 m;
• in case of vertical installation – a canopy preventing moisture from getting into the fan.

The outlet spigot must always be connected to the air duct.

ELECTRONICS OPERATION ALGORITHM

The fan speed without options can be controlled by voltage, as well as by thyristor controllers.
A speed controller can be purchased separately.
Warning! When adjusting the voltage, ensure that there is no unusual noise or vibration at reduced motor speed.
When adjusting the voltage, the motor current may exceed the rated current.
The fan is equipped with a thermal switch without self-reset.
Probable causes of the thermal switch tripping:

• non-compliance with the operating rules
• impeller jamming (clean the impeller)
• motor malfunction (turn off the unit, contact the Seller)

To reset the thermostat:

• Switch off the power supply.
• Find and eliminate the cause of overheating.
• Switch the power back on.

The Stream …T fan activates upon control voltage application to the LT input terminal by the 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-on delay time, turn the control knob T clockwise to increase and counter-clockwise to decrease the turn-on delay time respectively.
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 Stream …U/Un fan is equipped with a TSC electronic module (speed controller with an electronic thermostat) for automatic speed control (air flow) depending on the air temperature.
The terminal compartment incorporates 2 control knobs:

• presetting speed;
•  setting electric thermostat threshold value.

This indicator lights when the air temperature exceeds the set value.
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:
As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the fan operates with the set speed.
The Stream …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.

Stream EC
The EC 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 that enables switching the fan on/off and smooth speed (air flow) regulation from minimum to maximum value. Rotations are controlled from the minimum (extreme right position) to the maximum (extreme left position). When rotating counter-clockwise, the rotations increase.
• DIP switch in EXT position. The control signal is set by the R2 external control unit.

DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD

TECHNICAL MAINTENANCE

The fan surfaces must be regularly cleaned (once in 6 months) from dirt and dust.
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.
Do not allow water or liquid come into contact with electric components.
Wipe the surfaces dry after cleaning.
