MOUNTING & OPERATING INSTRUCTIONS IN STEPS
Before you start mounting the RSMFM-2R room transmitter, read carefully
“Safety and Precautions”. 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
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).

OPERATING INSTRUCTIONS
Calibration procedure:
Sensor calibration is not necessary.
In the unlikely event of CO2sensor element failure, this component can be replaced.
All sensor elements are calibrated and tested in our factory.
Bootloader
anks 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

Put a jumper onto pins 1 and 2 and wait
for at least 5 seconds to reset the Modbus
communication parameters

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).

NOTE By default, the LED indication refers to temperature measurements. is can be
changed to relative humidity or CO2values 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
e 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.
