Function Test

The MP-5000 controller contains a special function test that automatically tests individual components including the controller display, sensors, condenser fan, evaporator fan, compressors, etc. The test includes measurement of component power consumption and compares test results to expected values.

Note The function test does not test the actual performance of the complete system. Therefore it is not a pretrip test and should not be used instead of the PTI test.

With the unit turned On, allow it to start and stabilize and the display to show the unit status display (setpoint):

  1. Press the F1 key to open the F1 Menu.

  2. Use Down key to select the PTI Commands. Press Enter key to see the PTI Commands options.

  3. Press the Up or Down key to scroll to Function Test.

  4. Press the Enter key to start the Function Test. Display shows test currently being performed. The Function Test ends automatically. Press any key on the controller to return the unit to normal operation.

Any alarm codes recorded during the test can be viewed through the controller’s Alarm List menu at the end of the test.
