4. Naudojimo instrukcijos
The Honeywell L8124C1003 operates automatically to maintain boiler water temperatures within the set limits and control the circulator pump.
- High Limit Control: This function prevents the boiler water temperature from exceeding a safe maximum. If the water temperature reaches the high limit setting, the burner will shut off until the temperature drops.
- Low Limit Control: This function ensures the boiler water maintains a minimum temperature, often for domestic hot water production. If the temperature falls below the low limit, the burner will activate to reheat the water.
- Circulator Control: The Aquastat manages the operation of the circulator pump, typically allowing it to run only when the boiler water is at a sufficient temperature to provide heat to the system.
Periodically check the temperature settings to ensure they align with your heating requirements and system specifications.
5. Priežiūra
The L8124C1003 Aquastat Relay is designed for reliable operation with minimal maintenance. However, regular system checks are recommended.
- Kasmetinė apžiūra: Have a qualified technician inspect the Aquastat and the entire heating system annually.
- Švara: Ensure the area around the Aquastat is free from dust and debris to prevent overheating or interference with components.
- Laidų patikrinimas: During professional inspections, ensure all electrical connections remain tight and free from corrosion.
