Alarms
For easier troubleshooting, use the remote control on which all alarms are displayed.
See the Functional Description section in the user guide for how to activate the different
operating modes. Identify the problem in the left-hand column and follow the instruc-
tions on the right:
Alarm
Cause
Action
Yellow LED (30/min) and
beeping.
(The unit continues to oper-
ate but electricity consump-
tion and noise levels are in-
creased as a result of high
pressure loss in the dirty
filter).
The filters need to be
checked/replaced.
Replace the filters and re-
set the unit filter timer. See
Preventive Maintenance
Constant, red LED and
beeping.
The unit continues to oper-
ate in fail-safe mode (Fail
Safe Mode 1), which corre-
sponds to standard opera-
tion, but without access to
cooling function with by-
pass (not HCV 4).
Defect on T1 outside air
sensor or on T2 supply air
sensor.
Note that the unit in fail-
safe mode always keeps
the bypass damper closed
(not HCV 4).
Check and, if required, re-
place the sensor set.
Flashing red LED (30/min)
and beeping.
The unit operates in fail-
safe mode (Fail Safe Mode
2), during which the supply
fan operates only at lowest
speed (Fan Step 1) and the
extract fan operates at Fan
Step 1/2.
One of the following com-
ponents is defective or has
a bad connection:
T3 extract air sensor
T4 exhaust sensor
The built-in RH sensor
Or:
One of the two fans does
not achieve the required
speed
Check and, if required, re-
place the sensor set.
Check that the fans are
able to rotate unhindered
and that the cables are se-
curely connected.
