Multiple units operated from one control panel
The outputs always have a global effect: The signals are always
the same in all units connected to the control panel.
See also section 2.8.
The room temperature is displayed as default. With this
function you can select another temperature to display or
switch off the temperature display.
Some fault messages may be caused by external factors such as
the central heating system and do not necessarily have an
influence on the function of the air curtain.
Use this function to suppress these messages. Messages
concerning safety are always displayed.
When you are using an input, you can allow the effect of an
incoming signal to continue for some time after the signal has
passed (releasedelay').'
This setting can be used, for example, in combination with a
door switch to allow the unit to continue to run for a short
time after the door has been closed.
When the unit is switched off, the valve in the unit is closed by
default.
Valve open
Select and set the opening percentage of the valve
to always keep a flow over the heat exchanger into the unit.
When there is only a small difference in temperature between
outdoors and indoors, there is less need for a climate
separation. In order to save energy, the fans can be switched
off when there is only a small difference in temperature.
Set this value to zero to allow the fans to run at all times.
