Embraco Fullmotion CF10C - First Time Pull-down; Normal Cycling; Connection

CHAPTER 4. OPERATION 32
4.2.1 First time Pull-down
Aſter 3 minutes of intermediary speed, the speed is increased to maximum and it
is kept at this rotation until the thermostat opens, switching the compressor o.
4.2.2 Normal cycling
Compressor speed increases and decreases proportional to thermal load variation
during compressor running time. Optimum speed will be targeted to minimize en-
ergy consumption. If thermal load remains constant for a period longer than 20
minutes, the compressor speed is increased.

4.2.3 Connection
The Drop-In mode connection shall be wired according to Figure 4.3. The connec-
tion is an Energized Contact and must be used when the thermostat control signal
is energized directly from the AC phase. This signal is usually called Thermostat
Return Signal.
