Function: To Set Low Temperature Alarm Set Point for
Control (Main) Probe.
Once set at a particular value, this will not allow the Set
Point to go below this value.
Example: Setting this parameter at -40.0°C will not
allow the Set Point to go below -39.0°C (LS+1.0).

Function: To set Differential for Compressor.
Example:
If setpoint is set at 0.0°C and differential is set at 2.0°C,
then when the system reaches 0.0°C, the Compressor
relay will cutout and since the differential is 2.0°C, the
relay will cutin (restart) at 2.0°C (0.0°C + 2.0°C).
