5. Arahan Operasi

Once properly installed and connected to power, the Marley CDF557 heater operates automatically based on its thermostat settings.

5.1 Operasi Asas

1. Ensure the heater is connected to a live power supply.
2. Set the desired temperature on the external thermostat (if applicable, sold separately or integrated into a building management system).
3. The heater will activate when the room temperature falls below the set point.

5.2 Operasi Kipas

The heater's fan is designed for optimal comfort and efficiency:

• The fan will only begin to blow air into the room once the heating elements have reached the desired operating temperature. This prevents the circulation of cold air.
• After the heating cycle concludes, the fan will continue to operate for a short period to discharge all residual heat from the unit before shutting off completely. This maximizes heat transfer and prolongs component life.

5.3 Building Management System Integration

Optional relays are available to connect the CDF557 ceiling heater to a central building management system (BMS). This allows for centralized control and monitoring of temperatures across multiple units from a single location. Consult a qualified HVAC technician for integration with a BMS.
