4.7.5 Temperature sensor function (only I3 and I4)
 The external inputs I3 and I4 can be used as analogue inputs for temperature
measurement via remote sensor.
This function is activated on the General parameter page with the parameter function of the
external inputs I3 + I4.
The temperature measured at I3 can be used internally as an actual value for the RTC
(see Source for actual value parameter).
The temperature measured at I4 can be used internally as a floor temperature for the RTC. See
parameter Use floor temperature limitation (sensor at I4) on the Settings parameter page).
Notwithstanding the above, both measurement values can also be sent to the bus.
