SiBE341027 Detailed Control Functions
Function 47
2.4.2 Compressor PI 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]
Controls compressor capacity to adjust Te to achieve target value (TeS).
Te set value (Make this setting while in Setting mode 2.)
Te : Low pressure equivalent saturation temperature (°C)
TeS : Target temperature of Te (Varies depending on Te setting, operating frequency, etc.)
* On multi-outdoor-unit systems, this control is made according to values of the first-priority unit, which is detected with
the pressure sensor.
[Heating operation]
Controls compressor capacity to adjust Tc to achieve target value (TcS).
Tc set value (Make this setting while in Setting mode 2.)
Tc : High pressure equivalent saturation temperature (°C)
TcS : Target temperature of Tc (Varies depending on Tc setting, operating frequency, etc.)
* On multi-outdoor-unit systems, this control is made according to values of the first-priority unit, which is detected with
the pressure sensor.
