1) Only required for heating AND cooling applications (see section 3.6.6)
2) The shift is added to the local shift (LTE mode only)
3) The last intervention wins, either S-Mode input or local operation
The current setpoint (used by the thermostat for temperature control) is available
on the bus for use in the central control unit.
∂ The supported communication objects are different in LTE mode and S-mode
∂ Changes via the local HMI or via KNX have the same priority (last always wins)
∂ Adjusting the Comfort basic setpoint will reset the runtime Comfort setpoint to
the basic setpoint
∂ Central setpoint shift is used for summer / winter compensation in particular
∂ Setpoint shift does not affect the setpoints stored in parameters P08, P11, P12,
P33
∂ Local shift and central shift are added together
∂ Applies only to Comfort and Economy setpoints; Protection setpoints are not
shifted centrally
∂ The resulting (current) setpoint heating and cooling is limited by the Protection
setpoint; if Protection setpoint is OFF, then minimum 5 °C and maximum 40 °C
are used
∂ The resulting setpoints for cooling and heating of the same operating mode have
a minimum distance of 0.5 K between them
∂ The result of local and central shift, together with the room operating mode, is
used by the thermostat for temperature control (current setpoint)
