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). RMFPM-2R MULTIFUNCTIONAL ROOM CONTROLLER

6 - 11 back to the table of contents 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.

Do the wiring according to the wiring diagram (see Fig. 4). Fig. 4 Wiring 5. Put back the cover and snap it in. 6. Switch on the mains supply. 5. Optional settings To assure correct communication, the NBT needs to be activated in only two devices on the Modbus RTU network. If necessary, enable the NBT resistor via 3SModbus or Sensistant (Holding register 9). RMFPM-2R MULTIFUNCTIONAL ROOM CONTROLLER

ATTENTION  t Do not expose to direct sunlight! OPERATING INSTRUCTIONS Calibration procedure: Sensor calibration is not necessary. In the unlikely event of CO2 sensor element failure, this component can be replaced. All sensor elements are calibrated and tested in our factory. 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 Put a jumper onto pins 1 and 2 and wait for at least 5 seconds to reset the Modbus communication parameters 1 2 3 4 5 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 CO2) is between the minimum and maximum alert range values (Fig. 6 - 1). 2. When the yellow LED is on, the measured value (temperature, relative humidity or CO2) is in the alert range (Fig. 6 - 2). 3. When the red LED is on, the measured value (temperature, relative humidity or CO2) is below the minimum measurement range value or above the maximum value. Blinking red LED indicates loss of communication with a sensor (Fig. 6 - 3). RMFPM-2R MULTIFUNCTIONAL ROOM CONTROLLER

8 - 11 back to the table of contents Fig. 6 LED indications 3 2 1 NOTE By default, the LED indication refers to temperature measurements. This can be changed to relative humidity or CO2 values via Modbus Holding Register 79 (see Table Holding registers below). Green LED intensity can be adjusted between 0 and 100 % with step of 10 % according to the value set in Holding register 80. Ambient light sensor The measured light intensity in lux is available in Input Register 41. Additionally, an active and standby level can be defined in Holding registers 35 and 36. Input Register 42 indicates if the measured value is below standby level, above active level or in between both levels: ■ ■If the measured light level is below the Standby level, Input Register 42 indicates “Standby”. ■ ■If the measured ambient light level is above the Active level, Input Register 42 indicates “Active”. ■ ■If the measured ambient light level is between the active and stand-by level, Input Register 42 indicates “Low intensity”. When this feature is used, it is advisable to adjust the active and standby levels in Holding Registers 34 and 35 according to the actual ambient light conditions around the sensor. VERIFICATION OF INSTALLATION INSTRUCTIONS 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. RMFPM-2R MULTIFUNCTIONAL ROOM CONTROLLER
