Choose a smooth surface (a wall, panel and etc.). Follow these steps: 1. Using a flat screwdriver, remove the front white cover by releasing the snap-fits on its both sides (See Fig. 1 Snap-fits release). 2. Insert the crimped RJ45 cable through the opening on the rear plate and plug it into the socket (See Fig. 2 Mounting dimensions.) 3. Using suitable fastening materials (not supplied), position the room sensor at least 1,5 m from the floor. When planning the installation, allow enough clearance for maintenance and service. Mount the sensor in a well-ventilated area. Mind the correct mounting position and unit dimensions. See Fig. 2 and Fig. 3.

Optional settings If your unit is the first or the last unit on the Modbus RTU network (see Example 1 and Example 2), enable the NBT resistor via 3SModbus or Sensistant. If your device is not an end device, leave the NBT disabled (default Modbus setting).

OPERATING INSTRUCTIONS Calibration procedure: No relative humidity and temperature sensor calibration is necessary. By default, the sensor element is self-calibrating. Optionally, the sensor element can be calibrated and verified manually via SSCDM. For this purpose, the sensor element is removable. More information is available in the SSCDM datasheet and mounting and operating instructions. Bootloader Thanks to the bootloader functionality, the sensor firmware can be updated via Modbus RTU communication. To enter Boot mode, put a jumper onto pins 3 and 4 of the P1 header and restart the power supply (see Fig. 5). Once Boot mode is activated, the firmware can be updated via SM Boot application (part of 3SModbus software suite) or Sensistant. Fig. 5 P1 header 1 2 3 4 5 1 2 3 4 5 Put a jumper onto pins 1 and 2 and wait for at least 5 seconds to reset the Modbus communication parameters Put a jumper onto pins 3 and 4 and restart the supply to enter bootloader mode LED indications 1. When the green LED is on, the measured value (temperature, relative humidity or ) is between the minimum and maximum alert values (Fig 6-1). 2. When the yellow LED is on, the measured value (temperature, relative humidity or ) is in the alert (Fig 6-2). 3. When the red LED is on, the measured value (temperature, relative humidity or ) is below the minimum measurement value or above the maximum value. Blinking red LED indicates loss of communication with a sensor (Fig 6-3). Fig. 6 LED indications 2 1 3 NOTE By default, the LED indication refers to temperature measurements. This can be changed to relative humidity or values via Modbus Holding Register 26 (see Table Holding registers below). Ambient light sensor It measures the ambient light levels in order to activate or deactivate Input Register 6. There are two Holding Registers for setting Active or Standby light level in luxes. MIW--EN-000-30 / 03 / 2018 www.sentera.eu 7-10
If the measured light level is below the Standby level, Input Register 6 indicates Standby. If the measured ambient light level is above the Active level, Input Register 6 indicates Active. If the measured ambient light level is between the Active and Stand-by level, Input Register 6 indicates Low intensity, therefore it is advisable to set Active and Standby levels in Holding Registers 34 and 35 according to the ambient lighting. VERIFICATION OF INSTALLATION INSTRUCTIONS MODBUS REGISTER MAPS After switching on the power supply one of the LEDs lights up according to the status of the measured variable. If this is not the case, check the connections. INPUT REGISTERS Data type Description Data Values 1 Temperature reading signed int.
