DESIGN AND OPERATING PRINCIPLE

The fan casing is made of steel with an aluzinc anti-corrosion coating.
For easy installation and operation, the fan is attached to the surface using a special bracket.
Heat- and sound-insulation made of foam.
The round connecting spigots are rubber sealed.
The fan is equipped with an asynchronous electric motor with an external rotor and an impeller with forward curved blades.
The low-noise electric motor with ball bearings with specially selected grease ensures maintenance-free operation of the fan.
The duct fans are intended for mounting to round air ducts.
The fans are installed between the air ducts.
The fan is attached to the building structure using a bracket.
The fan may be installed in any position in consideration of the air flow direction (as indicated by the arrow on the fan casing).
ELECTRONICS OPERATION ALGORITHM
The Iso … G(T)I1/GS(I)1 fan is equipped with an electronic module TSC (speed controller with electronic thermostat) for automatic change of rotation speed (air flow rate) depending on the air temperature.
There are 2 control knobs on the cover of the terminal compartment:

• preset speed;
• operating threshold of the electronic thermostat.

The thermostat indicator is located on the fan cover.
It lights up when the air temperature exceeds the set value.
To set the thermostat threshold, turn the temperature control knob clockwise to increase the value and counter-clockwise to decrease the value.
To set the rotation speed (air flow), turn the speed control knob in the same way.
There are two operation algorithms – by temperature and by timer:
Iso … G(I)1: when the room temperature exceeds the set value, the fan switches to maximum speed.
When the temperature falls below the set threshold by 2 °C (or if the temperature was initially below the set threshold), the fan operates at the set speed.
Iso … GT(I)1: when the air temperature in the room exceeds the set value, the fan switches to maximum speed.
When the air temperature falls below the set threshold, the delay timer starts a 5-minute countdown, then the fan switches to the set speed.
Iso … GS(I)1: when the air temperature in the room exceeds the set value, the fan turns on at the set speed.
When the temperature drops below the set threshold by 2 °C (or if the temperature was initially below the set threshold), the fan turns off.
The Iso … FR1 fan is equipped with a speed controller that allows you to turn the fan on and off, smoothly adjust the rotation speed (air flow) in the range from minimum to maximum speed.

Caution! To reset the fan, disconnect its power supply mains.
