2.2
Compressor PI Control
2.2.1 For Z-Control
Carries out the compressor capacity PI control to maintain Te at constant during cooling
operation and Tc at constant during heating operation to ensure stable unit performance.
[Cooling operation]
[Heating operation]
2.2.2 For W-, X-, Y-Control
See chapter “Field Setting”.
Controls compressor capacity to adjust Te to
achieve target value (TeS).
Te : Low pressure equivalent saturation
temperature (°C)
Te set value (Make this setting while in Setting
mode 2.)
TeS : Target Te value
(Varies depending on Te setting, operating
frequency, etc.)
