Temperature Measurement

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

	Temperature measurement	Internal temperature
		Temperature calibration	- 5 – + 5 °C
		Send temperature when the result changes by	0 – 10 °C
		Cyclically send temperature	0 – 255, 0 = inactive
		Send alarm/telegram for low/high temperature	Do not send Send on read only Send on a change

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

The following applies:

Actual temperature = measured temperature + correction value

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 visualization software).

You can use one or a combination of both parameters.

In the last setting you can define a feedback method in case of a temperature sensor alarm (if the sensor sends a temperature that exceeds the preset threshold detection range).

The High/Low temperature alarm object sends the alert always when the temperature is below or above the threshold.
