10.7.5 Input for temperature reading
Options:
Internal measurement
External measurement
The parameter is used to specify whether the temperature is read via an internal or external
temperature sensor.
–
Internal measurement
: The following supplementary parameters are available:
Cyclic sending of the current actual temperature [min.]
:
Options:
Setting option from 5 - 240
The parameter is used to set the time intervals at which current temperature used by the
device is sent to the bus.
Difference of value for sending the actual temperature [x 0.1°C]
:
Options:
Setting option from 1 - 100
The parameter is used to set the temperature difference from which the current temperature
is to be sent. The temperature difference is calculated from the measured temperature and
the actual temperature sent last.
Compensating value for internal temperature measurement [x 0.1°C]
:
Options:
Setting option from -127 - +127
Each installation site exhibits different physical conditions, e.g. interior or exterior wall,
lightweight or solid wall. To ensure that the device displays the correct temperature,
measure the current temperature at the installation site with an aligned and/or calibrated
thermometer. The parameter is used to specify the difference between thermometer and the
actual temperature displayed on the device as "Adjustment value".
Note
To prevent faulty measurements, carry out the adjustment measurement
only after the device has adjusted itself to he environmental temperature.
It is recommended to repeat the adjustment measurement just prior to or
after occupying the room.
–
External measurement
: No additional parameters available.
10.7.6 Display actual temperature
Options:
Deactivated
Activated
The parameter is used to specify whether the current temperature is displayed.
10.7.7 Unit of temperature
Options:
°C
°F
The parameter is used to specify the unit with which the temperature is displayed.
