closed while not being pow-
ered
Continuity
check with a
tester

unit in heating operation
SVC
Provides refrigerant to indoor
unit in cooling operation
LEV
LEV1
1) Liquid level control
2) Pressure differential con-
trol
3) Subcool control
DC12V
Opening of a valve driven by a
stepping motor
41 - 3000 pulses
Same as
indoor LEV
LEV3
DC12V
Opening of a valve driven by a
stepping motor
0 - 2000 pulses
Pressure
0~4.15 MPa [601psi]
Vout 0.5~3.5V
0.071V/0.098 MPa [14psi]
Pressure [MPa]
=1.38 x Vout [V]-0.69
Pressure [psi]
=(1.38 x Vout [V] - 0.69) x 145
