Room temperature
To display a room temperature, corresponding temperature values are
expected on the nviSpaceTemp.
Controller function
The controller function can only be displayed and set using nviSccSync and
nvoSccSync.
The value in nviSccSync.heat_cool is used for display.
The controller function can only be set if the function in
UCPTenableHvacMode is enabled. It is only possible to switch between
controller functions that are entered in UCPThvacMode. The output is
done via the nvoSccSync.heat_cool.
Setpoint
In principle, setpoints can be specified in 2 different ways: relative to a
setpoint parameterised in the room climate controller or absolute. If the
standard variables nviStptOffsetFb and nvoSetptOffset are used for the
activation/request of the room climate controller, only a relative setpoint
display/presetting is possible. If the interfaces nviSccSync and nvoSccSync
are used, you can choose between both types of setpoint specification.
The setpoint to be displayed is either recorded as a setpoint shift via
nviSetptOffsetFb / nviSccSync.setpoint_offset or determined as an
absolute setpoint from the values nviSccSync.setpoint and
nviSccSync.setpoint_offset.
The setpoint can be incremented or decremented within the limits
specified in UCPTstptRange with the step size that must also be specified.
