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 register time set to 5 seconds. In addition, if the antifreeze thermostat
is opened, the 3rd safety level is immediately automatically maintained. In this case,
manual resetting of the thermostat followed by the CLIMATIC is obligatory
Room Overtemperature Safety System
Upper Room Air Limit
If the room temperature is greater than or equal to the setpoint [C39], the safety
system is activated. It automatically cuts out at a temperature lower than 3°C below
this setpoint.
Lower Room Air Limit
If the room temperature is less than or equal to the setpoint [C38], the safety system
is activate
Faulty Electrical Heater Batteries
The electrical heater battery safety thermostats act directly on the heater stage
contactors. This information is fed to the CLIMATIC via auxiliary contacts.
If the CLIMATIC gives the order to the heater to operate and if 5 seconds later the
auxiliary contact is still open, the heat safety system is activated and stops the electrical
heater assembly.
This safety system is automatically locked-out. In this case a manual reset is
obligatory.
Note: This fault is also displayed in the event of a contact "shunt".
Faulty Gas Burners
If there is a fault with the gas control boxes the heat safety system is activated and
stops the respective burner.
This safety system automatically cuts out on the CLIMATIC and the control unit
must be manually reset.
Faulty Humidifier (Flexy Only)
If there is a fault with the gas control unit for more than a minute, the safety system
is activated and stops the humidifier.
This safety system is automatically locked-out. In this case a manual reset is
obligatory.
Room Humidity Safety System
Lower Room Limit
If the room humidity is less than or equal to the setpoint [C40], the safety system is
activated. It automatically cuts out at a humidity of 3% above this setpoint.
Upper Room Limit
If the room humidity is greater than or equal to the setpoint [C41], the safety system
is activated. It automatically cuts out at a humidity of 3% below this setpoint.
