7. Outdoor Electronic Control Valve
(1) When the outdoor unit stops in cooling mode: 480 pulses
When the outdoor unit stops in heating mode: 0 pulses
(2) In cooling operation mode: 480 pulses
In heating operation mode: control of degree of superheating (∆T = gas temperature - liquid temperature) of the heat
exchanger
¶ ∆T should be 2 to 6 deg (that can be changed depending on the operation capacity).
¶ Control range: 75 to 480 pulses
