26.4 - Operation
When putting under voltage or when setting the time, the information on the machine status are updated as a function of the programming
settings.
The user can change the status of his unit (Run/Stop – ½ setting regulation) but if a time range or a holiday zone is active, the information
will be updated at the starting or ending time of the programming
In the case where at least one time range or one holiday zone is validated, the parameter P120 is forced on « 2 per console or BMS
» and cannot be modified.
When going under test mode, the programming becomes non active. When leaving the test mode, the unit status information are
updated as a function of the programming settings.
In case of range overlapping, the running mode has priority over the stop mode and setting 1 over setting 2.
Same thing in case of overlapping of zones
If a programme stage is active (# non validated) and the real day is selected, the status of the unit is as follows :
Type of programme
CSG1 -stop
CSG2 -stop
STP1-STP2
STP2-STP1
If at least one time range or one holiday zone is validated, alternate the message machine stopped or setting/temp with a
message in order to signal to the user that the status will be updated on next status change of time range. Display of each
of these messages for 3 seconds.
