The fan is equipped with a single-phase motor with an external rotor, equipped with a centrifugal impeller. The Duo models are supplied with a two-speed asynchronous motor.
The fan is rated for continuous operation.
Electronics operation algorithm
The VK U / U1 / U2 fan is equipped with an electronic module TSC (speed controller with an electronic thermostat) for automatic speed control (air flow) depending on the air temperature.
The terminal compartment incorporates 2 control knobs: Temperature regulator
• presetting speed
• setting electric thermostat threshold value
The fan is equipped with two indicators:
• temperature sensor indicator (hereinafter referred to as TSI) - yellow colour
Air flow regulator
• motor control indicator (hereinafter referred to as MCI) - green/yellow colour
When the fan turns on, the TSI indicates the unit operation algorithm:
• one pulse - U
• two pulses - U1

30°C min max
• three pulses - U2
The MCI lights up in green when the motor rotates and in red when it stops (or rotates very slowly).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 (air flow), rotate the speed control knob in the same way.
VK U : In this case, fan speed switching operations are rare.
The TSI lights up and the fan switches to the maximum speed as the room air temperature exceeds the set point.
As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the TSI goes out and the fan operates with the set speed.
VK U1 : The speed switching operations are more frequent as compared to the temperature-based functioning logic (U), but one speed interval continues at least 5 minutes.
The TSI lights up and the fan switches to the maximum speed as the room air temperature exceeds the set point.
As the air temperature drops down below the set point, the TSI starts blinking, the timer starts a 5-minute countdown and then the fan switches to the set lower speed and the TSI goes out.
VK U2 : The fan starts only at a certain air temperature.
The TSI lights up and the fan switches to the set speed as the room air temperature exceeds the set point.
As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the TSI goes out and the fan turns off.

READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT.
The fan is suitable both for horizontal or vertical mounting on the floor, on the wall or on the ceiling. Air motion in the system must be in compliance with the direction of the arrow on the fan casing. Install a hood on the intake spigot side in case of vertical fan installation. When installing the fan horizontally, provide a straight air duct section at least 1 m long on the intake spigot side.

Mounting sequence:
1. Remove the bolts on both sides of the casing, install the mounting brackets and tighten the bolts, aligning the holes in the brackets with the holes in the casing.
2. Mark holes for drilling.
3. Drill the holes in the wall or the ceiling for dowels.
4. Fix the fan with the screws.
5. Connect the air ducts of the corresponding diameter to the fan.

• The actual wire cross section selection must be based on the maximum load current, maximum conductor temperature depending on the wire type, insulation, length and installation method.
• The external power input must be equipped with an automatic circuit breaker QF built into the stationary wiring to open the circuit in the event of overload or short-circuit.
• The position of the external automatic circuit breaker must ensure free access for quick power-off of the unit.
• The trip current of the automatic circuit breaker must exceed the maximum current consumption of the unit (refer to the “Technical data” section or to the unit label).
• The recommended trip current of the circuit breaker is the next current in the standard trip current row following the maximum current of the connected unit.
• The circuit breaker is not included in the delivery set and can be ordered separately.
