Why won't the compressor start on my Daikin Chiller?
The compressor of your Daikin Chiller might not start due to high ambient conditions, a large switching rate (more than six hours at an ambient temperature of 55°C inside the switchbox), or other actions causing the heater sink temperature to increase.
What to do if my Daikin Chiller stops without an alarm?
If your Daikin Chiller stops operating without any alarm on the central controller, the thermal protection might be active. You can reset it by switching the power off and then on again after waiting for 10 minutes.
