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 [C41], 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 [C40], 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 [C42] or [C44], 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 [C43] or [C45], the safety system is
activated. It automatically cuts out at a humidity of 3% below this setpoint.
Faulty Pump
The internal protection of the water pump motor acts directly on the pump contactor. This information
is transmitted to the CLIMATIC™ via an auxiliary contact of the contactor.
If the CLIMATIC™ gives the pump the order to operate and if 5 seconds later the auxiliary contact
remains open, the safety system is activated and stops the pump.
The safety system is immediately automatically locked out. In this case, manual resetting is obligatory.
Note: This error is also displayed in the event of a "shunt" of the auxiliary contact of the contactor.
