6. Инструкция по эксплуатации
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.
- Цикл нагрева: 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.
- Работа вентилятора: The board controls the blower fan for both heating/cooling cycles and continuous fan operation if selected on the thermostat.
- Мониторинг безопасности: 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.
