Internal Temperature Sensor

The device has a built-in internal temperature sensor. You can set parameters for measuring and sending telegrams.

Extended settings	Internal temperature sensor
	Internal sensor compensation	0,1K * factor (- 30 – +30)
	Temperature unit	Celsius/Fahrenheit
	Object type selection	2 byte/4 byte/2 byte and 4 byte
	Send temperature when the result changes by	Disable/0,1 – 2 K
	Cyclically send temperature	0 – 255, unit = 1 min, 0 = inactive

You can set a compensation value for the sensor. This is useful, for example, if the device is mounted at an unfavourable position in the room. The temperature recording is different when exposed to a draught or close to sources of heat, for example, compared to other places in the room.

The following applies:

Actual temperature = measured temperature + compensation value

You can set the unit of temperature data. When you select Fahrenheit, the internal data convert before sending.

You can set two parameters for sending the measured temperature to the bus:

Temperature difference: The sensor compares the current temperature with the last value transmitted. If the current measured temperature is higher or lower than the selected deviation, the sensor sends the value to the bus.
Time interval: The sensor transmits temperature values cyclically after the preset time interval. (e.g. to visualisation software).

You can use one or a combination of both parameters.
