4.2 Drop-In control mode
The Drop-In mode is a Fullmotion CF10C Inverter control mode, where single ther-
mostat contact is used to set the compressor running conditions. Drop-In mode
allows the application to any refrigeration system with a simple ON/OFF thermo-
stat, without needing a control signal coming from an electronic thermostat. The
compressor speed will be adjusted automatically by the Inverter, in accordance to
the thermal load variation.
