OPERATION GUIDELINES
The fan is rated for connection to single‐phase AC power mains 220…240 V / 50/60 Hz.
The fan is designed for continuous operation always connected to power supply.
The arrow on the fan casing must match the air direction in the system.
Ingress protection rating against access to hazardous parts and water ingress is IPX4.
The fan is rated for operation at the ambient temperature ranging from +1 °C up to +45 °C.
The transported air temperature must not 60 °C.
CONTROL LOGIC
ILM XXX T starts operation as the external switch supplies a control signal to the LT input terminal, for instance,
during switching the light on. After a control signal is off the fan continues operating for the set time as adjusted from
2 to 30 min. To adjust the turn‐off time setting rotate the T time control knob clockwise to increase or
counter‐clockwise to decrease it accordingly (Fig.
29 ).
Warning!
The timer circuit is under mains voltage. Disconnect the fan from power mains prior to any adjustments and operations!
The fan delivery set includes a specially designed plastic screwdriver for fan settings adjustments.
Use it to adjust the fan turn‐off delay time or the humidity sensor set point. Do not use a metal screwdriver, knife, etc.
for adjustments not to damage the circuit board.
ILM XXX U (U1) is equipped with the electronic TSC module (speed controller with electronic thermostat) for automatic
speed control (air capacity regulation) depending on air temperature (Fig. 3 1 ).
The terminal compartment incorporates 2 control knobs:
for setting the fan speed;
for setting the thermostat set point.
The thermostat operating LED light is located on the fan casing. It glows as air temperature exceeds the set point.
To set the thermostat set point rotate the temperature control knob clockwise to increase or counter‐clockwise to
decrease the temperature set point accordingly.
