DESIGN AND OPERATING PRINCIPLE
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 double-speed asynchronous motor.
The fan is rated for continuous operation.
Electronics operation algorithm
The Centro ... G1(GT1/GI1/GTI1/GS1/GSI1) 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:
• presetting speed
• setting electric thermostat threshold value
The fan is equipped with two indicators:
• temperature sensor indicator (hereinafter referred to as TSI) - yellow colour
• 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 - G1(GI1);
• two pulses - GT1(GTI1);
• three pulses - GS1(GSI1).
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.
Centro ... G1(GI1): 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.
Centro ... GT1(GTI1): The speed switching operations are more frequent as compared to the temperature-based functioning logic
G1(GI1), 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.
Centro ... GS1(GSI1): 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.

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.
MOUNTING AND SETUP
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.

WIRING DIAGRAM
• The unit is rated for connection to power mains with the parameters specified in the "Technical specifications” section, according to
the wiring diagram.
• The connection must be made using durable, insulated and heat-resistant conductors (cables, wires).
• 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.
