Alarms

The CANAIRE control system uses dual alarm system with two levels of signals:

  • ALARM (“RED” alarm)

  • WARNING (“YELLOW” alarm)

Parent topic: CANAIRE Controller

RED Alarm

When any RED alarm appears in system:

  • Alarm icon SERVICE WRENCH shows on display.

  • Alarm acoustic signal sounds – long beep and then short beeps repeatedly.

Arrange repairs IMMEDIATELY.

Note Any RED alarm will disable the compressor. This means that cooling (and A/C heating in case of Heat Pump units) will stop working.

YELLOW Alarm

When any YELLOW alarm appears in system:

  • Warning TRIANGLE shows on display.

  • Warning acoustic signal sounds (one long beep).

Arrange repairs AS SOON AS POSSIBLE.

Alarm codes are stored in the memory to identify possible fault conditions. The alarm records can be displayed on the driver panel by long press of F button (3 s).

Alarm symbols can be removed by restart of control system (use the ON/OFF button to switch OFF, wait for 2 seconds, and then switch ON). After restart, the alarm symbol can appear again, if the reason for alarm still exists. If the alarm comes up again, don't restart the unit repeatedly, this will be of no benefit. Contact the service department or Thermo King representative immediately.
