Circuit connection test procedure.
The 3-Pipe system has a feature which enables it to check that the wiring and piping connections are
aligned with each other. This is carried out by allowing refrigerant to flow to one indoor unit at a time and
monitor the Indoor units coil sensor for a corresponding drop in temperature. Each Indoor unit is tested in
turn and where two Multi controllers are installed each Multi controller is tested in turn.
This test would normally be used at the commissioning stage.
Procedure for intialising the circuit test:
1.
Turn the power off.
2.
Ensure capacity codes are set correctly, capacity switches set to "0" are not tested.
3.
Set the Outdoor display switches SW1 and SW2 to 9 and Multi controller(s) display switch to 6.
4.
Turn the power back on.
5.
Set all the Remote controllers to cool mode and 29°C.
6.
Press the on / off button to start the Indoor units. The Outdoor LED's show "1020".
7.
Press the Outdoor unit switch SW3 for 3 seconds.
8.
The system is now in self-testing mode (LED's will be flashing).
9.
The system will stop at the end of the test.
In the event of cross wiring / piping the system will indicate which units are faulty, as shown by the LED's.
Refer to the table below.
