How to fix AERMEC NXP 0650 Chiller that does not start?
- J
  Jared WashingtonAug 15, 2025
  If your AERMEC Chiller isn't starting, here's what to check: * **Voltage:** Ensure there's electric voltage present and check safety systems. * **Switches:** Make sure the master, remote (if applicable), control panel, and main switches are all in the ON position. * **Circuit Breaker:** Verify the compressor magnet circuit breaker is ON. * **Power Supply:** Check for adequate power supply voltage. If the above steps don't resolve the issue, the remote control switch coil, circuit board, peak condenser, or compressor itself might be broken and need replacement.

What to do if AERMEC NXP 0650 Chiller compressor has high discharge pressure?
- R
  Rachel BarryAug 18, 2025
  If your AERMEC Chiller's compressor has high discharge pressure, consider these potential causes: * **Water Temperature:** High external or utility water inlet temperature. * **Air/Water Flow:** Insufficient air or water flow. Check fan operation, coil cleanliness, pump speed, and filter cleanliness. * **Fan Regulation:** Anomalous fan regulation operation. * **Air in System:** Air present in the hydraulic system. * **Refrigerant Load:** Excessive refrigerant gas load. To resolve, check the operational limits, bleed the circuit for air, restore the correct refrigerant load, and check/replace the fan if needed.

Why AERMEC NXP 0650 Chiller has insufficient yield?
- T
  Timothy PhillipsAug 21, 2025
  An AERMEC Chiller might have insufficient yield due to these reasons: * **Refrigerant:** Lack of refrigerant, possibly due to leaks. * **Dirty Components:** Dirty coils or a clogged water filter. * **Dimensioning:** Issues with the appliance dimensioning. * **Operational Limits:** Operation outside of operational limits. Solutions include checking for leaks and refrigerant load, cleaning the coils and filter, and verifying the appliance's dimensioning and operational parameters.

Why does AERMEC NXP 0650 Chiller compressor stop due to intervention of the protections?
- S
  shannonwoodAug 26, 2025
  The AERMEC Chiller compressor may stop due to intervention of the protections because of: * **Pressure:** Excessive flow pressure or low intake pressure. * **Voltage:** Low power supply voltage. * **Connections:** Badly fastened electric connections. * **Operational Limits:** Operation outside of operational limits. * **Component Issues:** Pressure switch malfunctioning or circuit breaker protection intervention. To address this, check the operational limits, power supply voltage, electric isolation of the windings, and replace the pressure switch if necessary.

What causes low discharge pressure in AERMEC Chiller?
- J
  Jason JacobsonAug 28, 2025
  Low discharge pressure in your AERMEC Chiller can be caused by: * **Temperature:** Low external air or inlet water temperature. * **Cooling Circuit:** Humidity in the cooling circuit. * **Air in System:** Air in the hydraulic system. * **Gas Load:** Insufficient gas load. To fix this, check the operational limits, empty and restore the gas load if there's humidity, bleed the circuit to remove air, and restore the correct gas load.

How to troubleshoot high intake pressure in AERMEC Chiller?
- T
  Terry FernandezAug 31, 2025
  High intake pressure in an AERMEC Chiller can result from: * **Temperature:** High external air or utility inlet water temperature. * **Thermostatic Valve:** Thermostatic expansion valve being too open or damaged. To resolve this, check the operational limits and adjust or replace the thermostatic expansion valve if it's damaged.

What causes low intake pressure in AERMEC NXP 0650?
- M
  Micheal RobertsSep 4, 2025
  Low intake pressure in an AERMEC Chiller can be attributed to: * **Temperature:** Low utility or external water inlet temperature. * **Thermostatic Valve:** A damaged or blocked thermostatic expansion valve. * **Flow Issues:** Insufficient water or air flow. Check fan operation, coil cleanliness, pump speed and filter cleanliness. To troubleshoot, check the operational limits, adjust or replace the thermostatic expansion valve if damaged, and ensure sufficient water and air flow.
