Value range of offset
The offset can be used to correct the measurement value if, for example, the measurement
deviates from a reference device.
•
The setting range is 0x01 to 0xFF; this corresponds to an offset range of
o
{-12.7 °C to +12.7 °C} or
o
{-12.7
kΩ to +12.7
kΩ}
•
One unit corresponds to 0.1 °C or 100
Ω
Value range "Range":
The "Range" parameter can be used to select temperature sensors with a positive or negative
temperature range.
•
0x00: Temperature sensors with a positive temperature range (factory setting)
•
0x01: Temperature sensor with a negative temperature range

Value range "Hysteresis":
The "Hysteresis" parameter can be used to reduce the DALI bus load. The event telegrams are
not sent until the measurement value has changed by the value of the set hysteresis.
•
The setting range is 0x00 to 0xFF; this corresponds to a hysteresis range of
o
{0.1 °C to 25.5 °C} or
o
{100 Ω to +25.5 kΩ}
•
One unit corresponds to 0.1 °C or 100
