Outdoor unit heat exchanger capacity control
Subcooled liquid refrigerant temperature
*1.
Single-dotted lines indicate wiring not supplied
with the unit.
*2.
Dot-dash lines indicate the control box boundaries.
*3.
Refer to the Data book for connecting input/output
signal connectors.
*4.
Daisy-chain terminals (TB3) on the outdoor units in the
same refrigerant system together
.
*5.
Faston terminals have a locking function.
Make sure the terminals are securely locked in place
after insertion. Press the tab on the terminals to
removed them.
*6.
Control box houses high-voltage parts.
Before inspecting the inside of the control box,turn of
f
the power
,keep the unit of
f for at least 10 minutes, and
confirm that the voltage between FT
-P
and FT
-N on
INV Board has dropped to DC20V or less.
