TTL Air curtain systems - control and automation panel type Touch
6. Operating modes and operating settings
For action with control and automation panel TTL-Touch is generally to defferentiate between a operation with
static values concerning to blow-out temperature and air volume and a operation with control functions.
The static operation without activated controllers is equal to conventional operation of air curtain systems. But
it is less effectiv by energetic respect, because the caloric requirement of air curtain unit keeps mostly constant
and only react to variations of water supply but will not adjusted to changing ambient conditions.
6.1 Operation without controllers
6.1.1 OFF mode
In the OFF mode the air curtain system is switched off, but in serviceability and can be activated for operation
by actuation of the buttons MANUAL/HAND mode or AUTOMATIC mode.

rate with adjustment of a continous alterable slider bar.
Perhaps connected door contacts, room sensors or room thermostates are without effect.
Howether fault messages as like motor faults or frost alert faults and with it associated switchings take place
for safety reasons.
6.1.3 AUTOMATIC mode (inactivated controllers)
6.1.3.1 AUTOMATIC mode
In AUTOMATIC mode the air curtain unit(s) will be switched On or Off by a external contact transmitter
(door contact or room hermostate) contacted at terminals 18/19 at internal connecting board
.
6.1.3.1.1 OVERRUN within AUTOMATIC mode
A overrun time for the AUTOMATIC mode can be set in menu 3.2 (Basic settings - Overrun time). In case of
shutup of the automatic contact (terminals 18/19 at the internal connecting board (PCB) inside the air curtain
unit) of the system installation, that means if the door closes, the air curtain unit will keep in operation for the
preselected time
.
The switch-off of air curtain device(s) by OFF button (0) at the Touch control panel doesn`t
disconnect automatically the power connection to the electricity grid. Electrical systems in-
side the air curtain unit as well as in the control panel and also the power cable and the data
lines may still be energized. The complete electrical disconnection of the air curtain device
from the mains will be effect exclusively by a repair switch provided by customer!
