What does it mean if I get a sensor or transmitter error on my Daikin Chiller?
If you're getting a sensor or transmitter error on your Daikin Chiller, the wiring may be incorrect. Check if the wiring matches the wiring diagram.
What does it mean when the alarm message indicates a sensor error code on my Daikin EWWD120MBYNN?
If the alarm message indicates a sensor error code on your Daikin Chiller, it could be that the suction temperature sensor isn't properly mounted in the suction pipe. Check the sensor and ensure it's correctly placed in its holder on the suction pipe.
What to do if my Daikin EWWD120MBYNN Chiller doesn't start, but the ON LED is on?
If your Daikin Chiller unit doesn't start but the ON LED lights up, several factors could be at play. First, ensure adequate water flow to the heat exchanger by increasing it. A refrigerant shortage might be the issue, so inspect for leaks and replenish if needed. Verify the unit operates within its specified range and that the inlet water temperature to the heat exchanger isn't too low; increase it if necessary. A dirty evaporator can also cause this, so clean it. Lastly, examine the flowswitch and water pump, and check if the low pressure safety setting isn't set too high.
Why does my Daikin Chiller run continuously and the water temperature is too high?
If your Daikin Chiller unit runs continuously, and the water temperature remains higher than the set temperature, first, check the temperature setting on the controller and adjust it if it's too low. High heat production in the water circuit could mean the unit's cooling capacity is insufficient. Also, a water flow that's too high could be the culprit, so recalculate it. Lastly, check the 'enable/disable capacity limitation' remote contact.
Why does my Daikin Chiller stop soon after operation?
If your Daikin Chiller unit stops soon after starting, it could be due to several reasons. Check if the schedule timer is activated and in off mode; adjust the settings or disable the timer. One of the safety devices might be activated. Also, test the voltage in the supply panel and the electrical compartment to ensure it's not too low, which could indicate a voltage drop due to the supply cables.
What to do if one of the safety devices is activated in my Daikin EWWD120MBYNN?
If one of the safety devices in your Daikin Chiller is activated, it could be due to a failure in one of the phases. Check the fuses on the supply panel or measure the supply voltage. Another cause might be voltage that is too low, so measure the supply voltage. Finally, it could be due to an overload of motor. In this case you should reset it. If the failure persists, call your local dealer.
Why does one of the circuits not start up in my Daikin Chiller?
If one of the circuits in your Daikin Chiller doesn't start up, it might be because the anti-recycling timer is active. The circuit can only start after approximately 10 minutes. Another reason could be that the guard timer is still active; in this case, the circuit can only start after approximately 1 minute. Also, the circuit might be limited to 0%, so check the 'enable/disable capacity limitation' remote contact.
What to do if my Daikin EWWD120MBYNN doesn't start, but the ON LED is flashing?
If your Daikin Chiller unit doesn't start, but the ON LED is flashing, the remote ON/OFF input might be active, and the remote switch is off. Turn the remote switch on or disable the remote ON/OFF input.
Why is my Daikin Chiller making excessive noises and vibrations?
If your Daikin Chiller is producing excessive noises and vibrations, it might not have been fixed properly. Ensure the unit is fixed as described in the installation manual.
Why is the compressor thermal protector activated in my Daikin EWWD120MBYNN Chiller?
If the compressor thermal protector is activated in your Daikin Chiller, it's because the compressor motor coil temperature is too high. This indicates that the compressor isn't being cooled sufficiently by the refrigerant medium.
