Port Setting Error. |
SW14 set incorrectly.
Too much capacity on a single port.
– R410a maximum is 140
– R407c maximum is 81 |
Confirm that SW14 is set according to where the unit is piped to on the BC box.
Also check the system is addressed correctly, especially if you have a sub BC box.
Make sure SW2 capacity settings are set correctly according to the unit model number. |
Use SW1/SW4 dipswitches on the outdoor unit to look at port settings. |
