(2) Target low-pressure and high-pressure control
In order to make the evaporation pressure of the indoor unit at the proper pressure on a variety of operations,
capacity of the compressor will be controlled by low-pressure sensor of the outdoor unit.
In order to make the condensation pressure of the indoor unit at the proper pressure on a variety of operations,
capacity of the compressor will be co
ntrolled by high-pressure sensor of the outdoor unit.
Target low-pressure and high pressure temperature depends on system capacity, capacity of compressor operation,
pipe length, and capacity shift switch settings.

2-2-3 Speed Range of Start, Stop, And Operation
On stop mode : 0 rps
On operating mode : 15 - 120 rps
(1) Heating starting process
*The compressr starting process in cool mode does not have the limitated hold controlling.
For Heating operation only, the upper limit speed at starting is made 40rps and is raised in
+10rps increments every 60 seconds.
