7. SETTINGS AND USE
HUMIDITY MODEL
The fan with TIMER-HYGRO control is designed for continuous general ventilation (24 hours) of humid
rooms, activation by humidity control in the range of 40% to 90% and an adjustable timer in the range of
0-15 minutes.
When the power is applied for the first time, the fan goes into test mode for few seconds, and during that
time the displays show the factory-set Timer-Hygro values.
To adjust the timer, turn the “TIMER” pin until the desired value appears on thedisplay (0’ to 15’).
To adjust the level of humidity, turn the “RH” pin until the desired value appears on the display (40% to
90%).
To adjust the continuous ventilation (for 24 hours), turn the “TIMER” pin clockwise to increase the time
until appears “EH” on the display, and the fan will operate at low speed.
When the level of humidity is higher than the set level, the Hygro function is activated and the fan will
operate at maximum speed.
Once the level of humidity falls below the set value, the device will continue to operate as maximum
speed for the period of time set in the Timer function and will eventually continue to operate at low speed.
The extractor fan will also start at maximum speed, if activated by the light switch in the room.
When the light switch in the room is turned off, the fan will continue to work at low speed.
To complete the assembly, check that all connections are properly made and that the cables are securely
installed and show no signs of damage.
Install the front panel in place and make sure it is properly installed in the locked position.
Make sure that the impeller blades turn freely.
