Table 46: Settings - Setpoint shift
The Basic Comfort setpoint is fixed parameterised via the ETS. This setpoint can be changed in two
ways. Firstly, a new absolute setpoint can be specified for the controller, this is done via the
"Comfort setpoint" communication object as a 2 byte absolute value and secondly, the preset
setpoint can be increased or reduced manually, this is done via the "Manual setpoint offset"
communication object, either via 1 bit or 2 bytes.
When a new absolute comfort setpoint is read in, the controller is assigned a new basic comfort
value. This new comfort value also automatically adjusts the dependent setpoints in the other
operating modes, as these are relative to the Comfort base value. All settings for setpoint shifting do
not apply here, as a completely new base value is assigned to the controller.
The second possibility for changing the setpoint is to shift the currently setpoint as a temperature
difference. The communication object "manual setpoint offset" is used for this. The 2-byte object is
used to send the controller a positive Kelvin value for raising or a negative Kelvin value for lowering.
With manual setpoint offset via the 1-bit object, only ON/OFF commands are sent and the controller
raises the setpoint by the set step width when a "1" is received and lowers the setpoint by the set
step width when a "0" is received.
During setpoint shifting, the parameterised basic comfort value as reference value for the other
operating modes is not changed
