• Fan turns on at temperatures above 40°C
• Control is done through a double thermostat

Power is supplied from the 230V AC network through the overcurrent switch.

4. Operation diagram (connection description)

• Power L (phase) led through the overcurrent switch
• From the switch:
• to the thermostat input
• Thermostat:
• contacts 11–12 → control of the heater
• contacts 23–24 → control of the fan
• Neutral wire (N):
• split by the terminal block
• common for heater and fan
• Protective wire (PE):
• connected to the heater
• then to the protective terminal (PE)

5. Safety measures

• Overcurrent switch B6A
• Protective grounding (PE)
• Enclosure protection class IP44
