Both the Comfort setpoint w and current setpoint w2 have the same values.
Heating mode Cooling mode
The Comfort setpoint w (value selectable via for example, rotary knob) is in the
middle of the dead zone (P055). The current setpoints w2.. (used by the thermostat
for temperature control) are at the boundaries of the dead zone.
w2h = Comfort setpoint (w) – ½ dead zone (X
dz
)
w2c = Comfort setpoint (w) + ½ dead zone (X
dz
)
● 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 will reset the runtime Comfort setpoint only
when P103 = 0
● Central setpoint shift is used for summer/winter compensation in particular
● Setpoint shift does not affect the setpoints stored in P011, P019, P020 and
P055
● Local shift and central shift are added together
● 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, then 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 shift, together with the room operating mode,
humidity control or setpoint track for cooling, is used by the thermostat for
temperature control (current setpoint)
● The room thermostat always adopts the setpoints received from the controller
RMB795B. Thus, the setpoints locally adjusted on the thermostats are
overridden by the setpoints from the room group (for example, 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 Master" functions
