Oil Control
This setpoint denes how the MicroVission will manage
the crankcase’s oil. When the compressor is used in cold
climatic conditions, it might be possible that compres-
sor does not start due to low crankcase oil temperature.
Oil Crankcase Heater Temperature
• When the oil temperature falls below this setpoint,
the oil heater (7th Digital Channel on Multi IO Board)
will turn ON. Note, there is a 2°F differential associ-
ated with this setpoint. For example, when set at
100 °F, the oil heater will turn ON at 98 °F and turn
OFF at 102 °F.
