6. Operating modes (cont.)
6.3.1 Overrun within AUTOMATIC mode
A overrun time for the AUTOMATIC mode can be set in menu 3.1 (Basic settings -
Overrun time
). In case of shu-
tup of the automatic contact (clambs 18/19 at the internal connecting board (PCB) inside the air curtain unit)
of the installation, that means if the door closes, the air curtain unit will keep in operation for the preselected
time.
6.3.2 HEATING mode within AUTOMATIC mode
In case of a switched-off automatic contact, the door is closed, the air curtain unit can activated for direct
room heating by using the HEATING mode within the cycle of AUTOMATIC mode.
The HEATING mode is active only if a room thermostat is connected at clambs 20/21 of the internal connec-
ting board (PCB).
If the room temperature is lower then the temperature adjusted at the room thermostat (accessory) the air
curtain switches ON at the preselected power level or operating stage (menu 5.2 Basic settings-
Heating stage
).
The AUTOMATIC mode and the WINTER mode (heating) have to be active.
The Automatic contact for the AUTOMATIC mode takes preference over the HEATING mode.
6.4 SUMMER/WINTER mode
The SUMMER/WINTER key switchover between an operation with activated heating battery (WINTER mode)
or an operation without heating (SUMMER mode) manually.
For using this function a selenoid valve or electrothermal valve have to be installed.
At activated WINTER mode (LED lights up) the valve is opened.
At activated SUMMER mode (LED is not illuminated) the valve is closed basically.
The functions SUMMER mode or WINTER mode can also be initiated by an associated BMS signal connected
at the clambs 26/27 on the internal connecting board (PCB) - see also chapt. 10.1 - Internal connecting board.
