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 [C88] 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 [C89] 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 [C90] 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 [C71], 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 [C72], 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 [C68], 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 [C69], 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 [C70] for more than
