Finesse VCS -F-B-10E, Руководство по эксплуатации, Страница: 10 / 55

There are the following push buttons on the E/DA
controller for electric heater: The air curtain is
switched ON and OFF by push button A. Automatic
operation mode is switched on by button B, manual
one by button C. The fan speed is set by three buttons
D, E, F, two levels of electric heat exchanger output
are set by buttons G, H. Switching of the air curtain,
set mode, set fan speed and set output of electric heat
exchanger are signalled by diode light above each
button. Electronic system does not allow the
unsuitable combination of push buttons. It means that
it is not possible to switch the electric heat exchanger
without switching the fans on first.
At minimum fan speed it is not possible to set
maximum output of electric heat exchanger
(buttons D and H together)!
Manual mode :
The functions are set by appropriate buttons marked
by graphic symbols in the manual mode (set by
button C). The connected external switches and
outdoor temperature sensor are ignored in this mode.
However, you can se the required fan speed by
buttons D, E, F and required output of the electric heat
exchanger by buttons G, H.
Automatic mode :
In the automatic mode (switched by button B)
depends the operation of the air curtain on the connected sensors /switches and the buttons D, E, F, G, H are inoperative.
How the function of the automatic control system for the air curtain with electric heater depends on the connected auxiliary
sensors/switches is clear from the following tables.

Function of the air curtain with connected outdoor temperature sensor and without any other
external switches
Electronic control system controls the fans speed and the electric heater output according to the outdoor
temperature see following Table. Reading accuracy - +/-3°C.
Function of the air curtain with connected outdoor temperature sensor and with door switch
When the door switch is used, the electronic control system respects, if the door is opened or closed - see
following Table. When the door is closed, the electronic system sets the slowest speed and lowest heating
output. When the door opens, the fans speed as well as the heating output is increased according to the
outdoor temperature. When the doors are closed again, the automatic system reduces the speed of fans
to the original speed with about 30 seconds delay. When the door is opened within this time period, the
delay function is cancelled and reactivated after the doors are closed again. When manual mode is on, the
door switch and outdoor temperature sensor are ignored. Reading accuracy - +/-3°C.
Function of the air curtain with connected outdoor temperature sensor and with door switch and
with room thermostat
Best air curtain function and maximum power savings are ensured when of using of door switch in
combination with room thermostat and outdoor temperature sensor. Thermostat can be used also for air
curtains with water heat exchangers, where it does not control its output, it is true, but it ensures the
switching the air curtain OFF in case the required temperature in the room has been reached. Fans speed
and output of the electric heater are controlled by the electronic system, which evaluates the signals from
external switches and sensors see following Table. Reading accuracy - +/-3°C.
