to enter the temperature menu. The display indicates the
present setting.
3. If this setting is correct, press the red button
to exit to the menu.
(The menu “t” re-appears”).
4. Press the blue button
to start the editing mode. If the present setting is “Auto”, press

The next menu is “t.CAL” if using the optional Remote Temperature Sensor to
measure the air temperature. If the Remote Temperature Sensor option is not fitted,
the next menu is “Ld.dEF” (see “Loading factory default values” on page 59).

5.4.11 Temperature calibration
Screen display:t.CAL
This menu option is offered if using the optional Remote Temperature Sensor to monitor air
temperature (see “Remote temperature sensor” on page 19). The recorded temperature can be
trimmed to match a another plant reading.
Note
The Remote Temperature Sensor is of a negative temperature co-efficient (NTC)
thermistor design.
Due to the effects of cable length and electronic component tolerances, the air
temperature measurement by the Remote Temperature Sensor could have an error of
±0.5 °C.
This menu option is in the engineering menu “Eng”. See “Accessing the engineering
menu” on page 49 or see Figure C-3 on page 79 for a map of the menu structure.
