The table below details the set point (SPC or SPF) parameter.
Display
Description
Defines the compressor cut-out temperature during the ready mode. The set
point (SP) temperature is the lowest measured temperature under normal
operating conditions.
The set point is displayed as SPC (set point Celsius) or SPF (set point Fahren-
heit) depending on whether the EMS controller is set to use Celsius or Fahren-
heit.
Considerations Must be above the freeze-up protection (dtt) temperature.
Range -9.9 to 9.9°C (14 to 50°F)
Global default
3.0°C (37°F)
ems75sz: -3.0°C (27°F)
