3. The signal wires must be in different colour for different terminal in order to avoid misconnection of polarity.
4. Check the address setting of the indoor unit:-
– Make sure the address settings are correct.
– Each indoor unit should have different address.
Outdoor unit checking:-
1. Check the no. of indoor unit settings are correct.
2. Make sure the capacity settings are correct.
3. Make sure the Master and Slave unit setting are correct (if applicable).
