If the input identifier for room temperature is configured in addition to the correctly
set control mode next to the input identifier extract air temperature, control always
occurs with extract air temperature.
The room temperature can be used for functions such as sustained mode, night
cooling to send to the bus or for display.
The effect of having one or several input identifiers connected at the same time is
described in detail in section 8.3 Special analog inputs.
