Panasonic PAPAMY1702034CE - Cooling Overload Control (Cool); Heating Overload Control (Heat); Extreme Low Temperature Compressor Low Pressure Protection Control (Heat)

43
14.5 Cooling overload control (Cool)
 This control detect outdoor pipe temperature and perform the compressor frequency restriction during cooling
operation.
14.6 Heating overload control (Heat)
 This control detect indoor pipe temperature and perform the compressor frequency restriction during heating
operation.
 This control detect outdoor ambient temperature and perform the fan speed adjustment during heating operation.
14.7 Extreme Low Temperature Compressor low pressure protection control
(Heat)
 This control is to prevent low pressure drops too low during extremely low outdoor ambient temperature to
improve the compressor reliability.
 During heating operation, when outdoor ambient temperature is in Zone 1, this control will be activated.
Compressor frequency restriction will be based on outdoor piping temperature.
