SAFETY AND ERROR CODES
The following text includes references such as [C11] and [V25]. They relate to the threshold or variable numbers used with the
KP02 unit.

Wrong Air Flow
If the pressure differential obtained by the analog sensor [V16] is less than the setpoint value
[C92] for more than 20 seconds, and if the blower fan has operated for more than 1 minute 30
seconds, the air flow safety system is activated and stops the ventilation.
The air flow safety system automatically stops after 1 minute 30 seconds and is automatically
locked out after 3 cut-outs in the same day. In this case a manual reset is obligatory. The cut-
out counter is reset to zero every evening at 20:00 if the value does not exceed 3 failures.
Dirty Filters
If the pressure differential obtained by the analog sensor [V16] is greater than the setpoint
value [C93] for more than one minute, the CLIMATIC™ indicates that the filters are dirty. The
unit is not stopped.
Missing Filters
If the pressure differential obtained by the analog sensor [V16] is less than the setpoint value
[C94] for more than one minute, the CLIMATIC™ indicates that the filters are missing. The unit
is not stopped.
SUPPLY AIR TEMPERATURE SAFETY SYSTEM
Supply Air Overtemperature Limit
1st Safety Level
If the supply air temperature is greater than or equal to the setpoint [C74], the heat control
system starts to reduce progressively. The control cycle will recommence normal operation for
a temperature lower than 3°C below this setpoint.
2nd Safety Level
If the supply air temperature is greater than or equal to the setpoint [C75], the safety system is
activated. The safety system automatically stops at a temperature lower than 3°C below this
setpoint.
Supply Air Temperature Too Low
1st Safety Level
If the supply air temperature is greater than or equal to the setpoint [C71], the cold control
system starts to reduce progressively. The control cycle will recommence normal operation for
a temperature in excess of 3°C above this setpoint.
2nd Safety Level
If the supply air temperature is less than or equal to the setpoint [C72], the unit automatically
positions its fresh air damper to the all air recycled position and cuts out cold production. This
safety level automatically stops at a temperature in excess of 3°C above this setpoint.
3rd Safety Level
If the supply air temperature is less than or equal to the setpoint [C73] for more than 15
minutes and for 15 minutes after the fan has started, the "supply air temperature too low" safety
system is activated. The unit shuts down completely.
This safety system cuts out if the supply air temperature is greater than 3°C above this setpoint.
It is automatically maintained after 3 cut-outs in the same day, and in this case a manual reset
is obligatory. The cut-out counter is reset to zero every evening at 20:00 if the value does not
exceed 3 failures.
NOTE : If a unit has a hot water battery, the temperature setpoint value is fixed at +6°C and the
