Individual setpoints

"Setpoint heating" is the default setting. In regions where the cooling function
is more important, it is recommended that you change this parameter to
"Setpoint cooling". This makes it easier to set the ambient temperature
controller and raise the cooling setpoints (standby temperature cooling
and automatic night setback).

If individual setpoints are used, individual setpoints are parameterised for
every operating mode ("heating setpoint comfort mode", "heating setpoint
standby", "heating setpoint night mode", "cooling setpoint comfort mode",
"cooling setpoint standby" and "cooling setpoint night mode").
In contrast to the dependent setpoints, the individual setpoints are retained
even after a manual setpoint adjustment. For example, if the user manually
adjusts the setpoint of the specified temperature "heating setpoint comfort
mode" up or down, the parameterised value "heating setpoint standby"
is always called when standby mode is enabled. This means that only
the fixed setpoints for the individual operating modes are called.
The user can manually change the parameterised setpoints with the two
push-switches "increase temperature" and "reduce temperature". Push and
hold the "increase temperature" push-switch (approx. 1 s) to switch between
"heating setpoint comfort mode" and "cooling setpoint comfort mode" in
the heating setpoint and the "reduce temperature" push-switch in the cooling
setpoint.
The parameterised setpoints for can be changed as much as desired for any
operating mode over the bus, even without the ETS. A 2-byte temperature
value must be sent to the corresponding communication object "setpoint
heating comfort", "setpoint heating standby", "setpoint heating night mode",
"setpoint frost protection", "setpoint cooling comfort", "setpoint cooling
standby", "setpoint cooling night mode" or "setpoint heat protection".
The received values are written to the device memory and are retained even
after a bus power failure and restoration. New setpoints can also be sent
to the device in the event of changes in room usage, such as by
visualisation. A new parameterisation is not required.
