Ideal Logic Air fault 370-F24

What it means

Heat Pump fault F24: circulation pump error.

Likely causes

1. Circulation pump failure
2. Pump blocked or seized
3. Wiring fault to pump
4. Frost accumulation on evaporator due to outdoor humidity/temperature conditions
5. Electrical interference from inadequate cable separation
6. Water ingress from improperly routed cables or loose cable glands
7. Dwelling room temperature dropped to ≤8°C
8. Inadequate corrosion inhibitor dosing leading to gradual system performance deterioration
9. Missing or undersized system filter allowing debris into primary circuit
10. Dwelling ambient temperature at or below 8°C
11. Ambient air temperature at or below 1°C
12. Refrigerant leak from circuit

Where to start

1. Read Primary flow temp, Hot water temp, Outside temp, Primary water flow, Compressor %, CH1 Pump, CH2 Pump, Diverter valve, Immersion heater status directly from home screen to verify system operation
2. Identify 'Alarm' symbol to indicate a plant error
3. Identify 'Maintenance/Special operations' symbol for maintenance message or special operation feedback
