Page 17: Operation And First Ignition
4.3 Operation and first ignition The device can work in two different modes, which will be described below. AUTOMATIC MODE This operational mode allows bringing the temperature of the oven to the set point using the "-" and "+" buttons. The REG_CK device will constantly detect the oven temperature by means of the thermocouple and will communicate to the ignition/flame control device the power level to be implemented on the gas valve in order to reach the set point in a controlled manner. - Page 18 AUTOMATIC mode Display Parameter / Description “tC” – Control time The “tC” parameter represents the execution time of the system's PI controller, expressed in seconds.

Page 21: Cleaning And Maintenance
Display Description NC – Not Connected The REG_CK regulating device is not connected to the flame ignition and control device. Check the connection between the two devices (“CV” cable, see section “Connection diagram”). OT – Over Temperature Exceeding the intervention temperature at automatic reset (550 °C). The system will automatically restore the heat command when the temperature measured by the probe is lower than 520 °C. - Page 22 The venturi of the burner must be cleaned with soap and water or non-abrasive detergents; Never wash the equipment with direct high pressure jet of water. Warning! If the ignition and control devices show any handling difficulties, contact the manufacturer immediately and it will provide for maintenance.
