Setpoint priority

A6V11545892_en--_c
The supported communication objects are different in LTE-Mode and S-Mode
Changes via the local HMI or tools have the same priority (the last option is
always used)
Setting the Comfort basic setpoint resets the runtime Comfort setpoint only
when P103 = 0
Central setpoint shifting is used for summer/winter compensation in particular
Setpoint shifting does not influence the setpoints stored in P011, P019, P020
and P055
Local and central shifts are added up
Applies only to Comfort and Economy setpoints; Protection setpoints are not
shifted centrally
The current setpoint heating and cooling is limited by the Protection setpoint. If
the Protection setpoint is Off, both the minimum 5 ° C and maximum 40 ° C are
used
The current setpoints for cooling and heating of the same operating mode have
a minimum distance of 0.5 K
The result of local and central shifting, together with room operating mode,
humidity control or setpoint tracking for cooling, is used by the thermostat for
temperature control (current setpoint)
The room thermostat always takes over the setpoints received from the
controller RMB795B. Thus, the setpoints adjusted locally on the thermostats
are overridden by the setpoints from the room group (e.g., every 15 minutes)
On RMB, the circumstances under which the controller sends out the
setpoints can be defined. Refer to CE1P3122 for "Setpoint priority" and
"Setpoint Manager" functions
