The speed button is used to change the speed or to turn off the device. With repeated taps you pass, in
sequence, from minimum speed, average speed, maximum speed, to the appliance is switched off. Three tiny
LEDs next to the button will give feedback about which speed the unit is operating at.
The recovery button activates an intermittent ventilation with heat recovery, visual confirmation is given by the
LED next to the button.
The ventilation button activates continuously the ventilation in only one direction (supply or extraction). The
direction is determined by the position of the dip-switches (see next chapter). The selection confirmation is given
by the LED next to the button.
Note: In this mode no heat recovery will take place.
The LEDs have the following meaning:
Filter: this LED turns on every 90 days and indicates the need to check the filters. For more details on how to clean
or replace the filters, refer to the maintenance section. If multiple devices are connected in series and one of
them requires the replacement of filters, the master unit LED will remain lit while the affected device LED will blink.
This LED goes off as soon as the filters will be replaced.
Alarm : this LED, if on, indicates an internal fault in the device. If multiple devices are connected in series and one
of them has a failure, the master device LED will remain on while the affected device LED will blink.
Master
: this LED, if it is on, indicates that the device is deployed as master within a set of devices connected in
series.
When all three LEDs are blinking together, it means that humidity-based control was activated through dip-switch
setting (see also par. 5.3 - DIP SWITCH SETTING), and that the set humidity threshold was reached. During this time
Kers will operate at maximum speed and it will not be possible to change the speed either from remote or from
on-board buttons. Once room humidity is below the set threshold, Kers will revert to the previously set speed.
5.2 REMOTE CONTROL
The operating distance of the remote control may be affected by the environment in which it operates.
Control capabilities of the remote control:
- “ ON-OFF ” button: it turns on and off the unit. N.B. you can turn the unit on and off only when the
appropriate dip has been correctly set on the machine. For more details, refer to the section "setting of
the dip.”
