Caution The basic setpoints are stored in a non-volatile memory in the RXC controller with a limited number of write cycles. It is therefore extremely important to avoid frequent
modification of any of these values! Instead of using a time scheduler, for example, to modify the setpoints on the basis of the time of day, the same effect can be
achieved by changes the operating mode (e.g. between Comfort and Pre-comfort. It is also possible to implement temporary setpoint changes via a setpoint shift
(@TCRn.RRSC).
Note From CFE Version V2.1 the basic setpoints can, optionally, be synchronized when the controller is powered on.
Refer to the V2.1 release notes on this subject.
