DVC/DVH Inverter Mini-Split Heat Controller
Remark:
Use a multimeter to test the DC
voltage between the L2 and S
terminals of the outdoor unit.
The red pin of the multimeter should
connect to L2 terminal while the black
pin is for the S terminal.
When the unit running normally, the
voltage will alternate between -50V to
50V.
If the outdoor unit has a malfunction,
the voltage will alternate with positive
voltage values.
If the indoor unit has malfunction, the
voltage will be a constant value.
Remark:
Use a multimeter to test the
resistance of the reactor (which does
not connect with the capacitor).
The normal value should be around
zero ohms. Otherwise, the reactor
has malfunctioned and needs to be
replaced.
