- Zatvori pristupnu ploču: Čvrsto zatvorite pristupnu ploču peći.
- Vrati snagu: Vratite električno napajanje peći na glavnoj servisnoj ploči.
- Probni rad: Initiate a heating cycle and observe the furnace's operation to ensure all functions (e.g., igniter, blower fan, heat output) are working correctly. Check for any diagnostic error codes.
6. Uputstvo za upotrebu
The Nordyne 624644 control board operates automatically in conjunction with your thermostat and furnace components. Once properly installed, its function is to manage the sequence of operations for heating and cooling cycles.
- Ciklus grijanja: When the thermostat calls for heat, the control board initiates the igniter, opens the gas valve, monitors the flame, and then activates the blower fan to distribute warm air.
- Cooling Cycle (if applicable): When the thermostat calls for cooling, the control board activates the outdoor condenser unit and the indoor blower fan.
- Rad ventilatora: The board controls the blower fan for both heating/cooling cycles and continuous fan operation if selected on the thermostat.
- Sigurnosni nadzor: The board continuously monitors safety devices such as limit switches and flame sensors. If a fault is detected, it will shut down the furnace and display a diagnostic code.
Refer to your furnace's specific user manual for detailed operating instructions related to your complete heating and cooling system.
