E1
Communication
error
Air Curtain PCB
[internal pcboard]
do not communicate.
Try to reset the alarm. Check connections, modular cables and
terminals, between all units and components. Systematically shift
position of communication cables to identify a broken terminal or
cables.
ID is set to 0 [Unit is running
continously].
Set an ID, run a Manual system check.
Cables are not original.
Make sure communication cables are correct [SchwankAir original
cables has a circuit diagram indicating how the contacts shall be
crimped on to the cable.]
The unit won’t start.
In multiple unit system, check that you have 230VAC to all units.
In Installer menu - Installer status screen, check that all units ID are
listed and that no extra units are listed.
When all units are powered up run a Manual system check.
Disconnect power, set ID=0 and reconnect power to test the Air
Curtain PCB pc-board.
Perform a factory reset and reboot the system
[disconnect/ reconnect power].
Visual damage to Air Curtain
PCB
Hardware failure - replace the Air Curtain PCB pc-board.

E2
ID Error
Two or more Air Curtain PCB
have the same ID.
Try to reset the alarm. Make sure all units have different
ID-settings and perform a Manual system check.
E3
Program error
[No program]
One or more Air Curtain PCB do
not have program.
Try to reset the alarm. Disconnect power, set ID=0 and reconnect
power to test the Air Curtain PCB pc-board - result? If the unit is
running act as if it was an E1 Communication error. If it is not running,
contact SchwankAir technical support.
E4
Room sensor
error
Fault on or missing external room
sensor Room Temp. Sensor
[Optional] connected to
Air Curtain PCB.
Try to reset the alarm. Check connections and cable. False errors can
occur in conjunction with communication error, check that all other
alarms have been reset. Measure resistance, 47kOhm at 25°C.
If the sensor intentionally has been removed, run a Manual system
check to exclude it from the system.
Wrong temperature is displayed
Try to reset the alarm. Disconnect power, set ID=0 and reconnect
power to test the Air Curtain PCB pc-board - result? If the unit is
running act as if it was an E1 Communication error. If it is not running,
contact SchwankAir technical support.
E6
Return water
temp. sensor
error.
Fault on or missing Return water
sensor SIReWTA connected to
Air Curtain PCB.
Try to reset the alarm. Check connections and cable. False errors can
occur in conjunction with communication error, check that all other
alarms have been reset. Measure resistance, 47kOhm at 25°C.
If the sensor intentionally has been removed, run a Manual system
check to exclude it from the system.
Wrong temperature is displayed
in Controller.
Try to reset the alarm. Disconnect power, set ID=0 and reconnect
power to test the Air Curtain PCB pc-board - result? If the unit is
running act as if it was an E1 Communication error. If it is not running,
contact SchwankAir technical support.
