Seal the conduits to avoid influencing the sensor by draught. Use insulating pad when
installing the sensor on cold walls. Avoid sensor exposition to sunlight or other heat
sources.
Opening the
cover
When removing the display part, proceed as follows:
-
press gently the side parts of the unit and pull the right of the display part by
several millimeters
-
pull the left of the display part
-
pull the display part and remove it from the bottom.

Over Modbus, it is possible to set / reset the complete symbol set except for the 7
segment digits, „Error“ and „Setting“ texts, and symbols of °C, °F, %, and rH. Those are
part of the configurable menu profiles. The register description is available in a separate
document

Communication description.
The integrated temperature sensor range is -20 to +70
°C. Read and entered values are
available at the RS485 bus where a controller or SCADA reads them. The supervising
system can also write values to the unit (operation mode, fan stage, etc.), which are
displayed on a large LCD display. Models with digital inputs and outputs also have those
data available. It is possible to control the sunblind operation as central building
function, such as „fully closed“ at night time, „fully open“ at strong wind, etc.
Those
commands must be programmed in the BMS and communicated over the RS485 bus to
the room unit. A control algorithm must be implemented in the master; for
independent communicative control use the UC..., FC... controllers.
RoHS notice
The device contains a non-rechargeable battery which backups the real-time clock and
part of the memory. After the device is not operable, please return it to the
manufacturer or dispose of it in compliance with local regulations.
