Command FC is used to set the temperature limits for activation and deactivation of the cooling device.

Structure

Command		Notes
CommandID	FC	FC works in all XLC4 operating modes
Parameter	None
	off_temp
	on_temp
	save state
Parameter	Value	Description
None		The current values for off_temp and on_temp are queried
off_temp	Decimal number	The connected fan is switched off if the maximum of the measured temperature values are below the level of off_temp Values: “0” switches the fans off “1” switches the fans on
on_temp	Decimal number	The connected fan is switched on if the maximum of the measured temperature values are at the level of on_temp Values: “0” switches the fans off “1” switches the fans on
save state	“W”	The values are stored permanently
Response
	fc , space , off_temp, “,” on_temp
General notes
	The new values are applied immediately. FC is available in firmware release from V4.22

If a cooling device is connected to VOUT or SW1-SW2 and the corresponding flag in FARegister is set, the working range of the device is defined by the warning levels stored in Corona II or the temperature levels set with the FC command.

Example

Query	Response	Action
FC 50 , 55	fc 50 , 55	off_temp is set to 50 °C on_temp is set to 55 °C
FC 50 , 55 W	fc 50 , 55	new values are set and stored
FC 1 , 1		The fans are switched on independent of the temperature settings
FC 0 , 0		The fans are switched off independent of the temperature settings

If the levels of on_temp and off_temp are set to 0, the warning levels stored in the Corona II module are used for fan switching. In this case, a hysteresis of 5K is implemented. If the warning level is set to 60 °C, the fans are switched on at 60 °C and off again if the temperature value is below 55 °C.
