LL: one speed model.
LL T HR: on this model the PCB is connected to a humidity sensor. The appliance provides two operating modes: "Timer"
operation and "HR Off" operation. One of these two types of operation must be chosen during configuration.
TIMER operation
The device allows setting 4 different working modes (below mode 1..4). The first two modes can be enabled manually,
the third and the fourth one are completely automatic.
Mode 1: the motor is started on speed V1 (minimum or maximum, as set during configuration) by pressing switch 1, after
a delay of 0 or 45 seconds. The motor will switch off after a run time of 6, 12, 18 or 24 minutes from the moment of turning
off switch 1. Instead of the switch it is possible to use a button, which must be pressed for at least 0.5 sec.
Note for the installer: if using the button you need to set the appliance switch-on delay to 0.
Mode 2: pressing switch 2 (with switch 1 off) starts the motor immediately: the operating speed is V2 (minimum or
maximum, as set during configuration). With switch 2, you can also stop the motor immediately.
Mode 3: The motor starts automatically when the humidity sensor detects a relative humidity higher or equal to an
adjustable threshold level at 60%, 70%, 80%, 90%. The operating speed is V1 (minimum or maximum, as set during
configuration). The motor will stop when the humidity drops by a value of 15 compared to the threshold value (e.g. from
60%RH to 45%RH)
In order to avoid continuous day and night operation of the extractor fan, in the event of bad weather, when the system
would not be able to reduce the humidity with ventilation, the appliance behaves as follows:
if the humidity does not drop by 15% RH under the set threshold within 2 hours of operation, the appliance will switch off
for a time of 8 hours. From this moment onwards, in order to ensure a minimum flow of air, the appliance will run on/off
cycles (2 hours on, 8 hours off). When the relative humidity drops by 15% RH under the set threshold the appliance will
automatically return to the standard operation of mode 3.
Mode 4: the motor starts automatically when the sensor detects a rapid increase in humidity (not necessarily higher than
the preset threshold value; it is a sudden increase in relative humidity, higher than 20% in 10 minutes). The operating
speed is V1 (minimum or maximum, as set during configuration). The motor will stop when at least one of the following
conditions occurs:
• the relative humidity falls by a value of 15%RH compared to the value that caused the motor to switch on
• after 2 hours of operation.
All the variable parameters described above are configured on a value set during installation. The manual operations can
overlap the automatic ones and vice versa (examples:
1. modes 1 and 2: manual start and stop;
2. modes 1 and 2: automatic stop after 2 operating hours).
HR OFF operation
With this configuration, you can temporarily disable the action of the humidity sensor. The function is enabled by pressing
switch 1 (in this way the sensor HR intervention is prevented), and it is automatically disabled an hour after the stop (this
means the HR sensor operation is restored). Instead of the switch it is possible to use a button, which must be pressed
for at least 0.5 sec.
When the function is active there is only one possible operating mode:
the motor is started and stopped manually with switch 2. The operating speed is V2 (minimum or maximum, as set during
configuration). However, when the function is not active the automations for modes 3 and 4 are operational.
N.B.
When using the wiring diagram in Figure 22 b, the humidity control cannot be disabled (models 100-120 LL T HR); you
need to set the "Timer" operating mode (switch 6 = OFF in "DIP-switch" Table).
LL MOTION: on this model the PCB is connected to a MOTION presence sensor. The appliance permits one operating
mode: the motor is activated at speed V (minimum or maximum, as set during configuration) by the MOTION presence
sensor tripping. The motor will switch off at the end of the sensor signal, after a delay of between 3 and 20 minutes (as
set during configuration, see "Instructions for the Installer).
LL T: On the electronic board there is a trimmer that allows you to set the duration of the shutdown delay
(Factory setting on 3 minutes.) By acting on this trimmer it is possible to modify the delay time, up to 20
About a minute (Fig.20a).
