1. 1

   Verify the temperature set point and the actual measured temperature values within the Otis 400's diagnostic interface or associated building management system to confirm the reported deviation.

2. 2

   Inspect power supply cabling and connections to the refrigeration unit's main contactor or power distribution module for loose terminals or visible damage.

3. 3

   Measure the supply voltage at the input terminals of the refrigeration unit's control panel or motor starter to confirm adequate power delivery.

4. 4

   Check the operational status and parameters of the refrigeration unit's compressor and condenser/evaporator fans via the Otis 400's monitoring interface or the unit's local controller, looking for fault codes or abnormal readings.

5. 5

   Inspect temperature sensor wiring and connections for integrity and proper termination, ensuring accurate temperature feedback to the control system.
