-
The contact can change the switching logic by
switching the jumper to NC or NO switching logic
(factory setting)
4.2.3.1.
Technical Parameters of External Contact EXT1
o
Switching voltage 24 VDC / 5 mA.
4.2.3.2.
Functionality of the Unit when Controlled by External Contact EXT1
-
External contact switches the unit on and off (the same functionality as on the ON/OFF button
controller) with logical termination or activation of all running processes at the time of switching off,
on.
-
If the unit is switched on/off by an external contact, it can be switched off/on by the controller on the
unit.
-
An example of the external contact functioning – a timer is used as an external contact:
o
EXT1 activates the unit at the given time (in the morning) – the unit operates according to the
user settings,
o
during operation, the unit is switched off by the controller on the unit – the unit switches off,
o
EXT1 switches the unit off at a given time (in the evening) – the unit remains switched off,
o
EXT1 activates the unit at the given time (the following morning) – the unit works according to
the user settings.
-
If you want to prevent control of the unit by unauthorised persons and you want to control the unit
by external contact, we recommend that after setting the unit parameters, you activate a child lock,
which prevents access to unauthorised persons (the unit cannot be switched off on the unit
controller). his ensures that the unit is switched on/off only via an external switch.
4.2.4.
External Contact Connection – BOOST (EXT2/FILTER)
-
The unit control allows the connection of an external button (damper switch with automatic damper
return - e.g.: bell button with return spring) to start the shock ventilation regime for a set period of time
- BOOST (hereinafter referred to as BOOST)
-
The BOOST regime is designed for shock ventilation for a certain period of time in rooms with an
immediate need for ventilation e.g.: bathroom, toilet etc..
-
The BOOST regime is indicated on the unit's controller by flashing the 8LED diode
4.2.4.1.
Technical Parameters of External Contact - BOOST
-
The external contact is designed as potential-free
-
Switched voltage 24 VDC / 5 mA.
4.2.4.2.
BOOST regime functionality
-
When the button (damper switch with automatic damper return) is pressed, the BOOST regime is
activated
o
The BOOST regime is activated and the unit starts at the set air output and run time.
o
After the set BOOST regime run time is over, the unit returns to its previous regime.
-
If you wish to exit BOOST regime before the set run time.
o
Hold the button for approx. 2 s.
o
The BOOST regime is automatically ended, and the unit returns to its previous regime.
-
BOOST regime factory setting:
o
Air output in the BOOST regime - max air output of the unit
o
Duration of the BOOST regime - 1 min
-
The air output and duration of the BOOST regime is adjustable in the customer menu, see chapter 5.5.
-
If necessary, it is also possible to start the BOOST regime directly at the unit controller, see chapter
5.4.2.
