1 Commissioning
1.1 Mounting room units
The device can be installed in dry surroundings (IP20) by screws on the wall surface or on the standard
flush mounting box. The recommended installation height is 150...180 cm.
The device position should be selected carefully. All the error factors that can affect to the
measurements should be eliminated as well as possible. The following list defines the typical
measurement error factors.
• direct sun light
• occupant proximity
• air flow coming from windows or doors
• air flow coming from ventilation nozzles
• air flow coming from the flush mounting box
• differential temperature caused by external wall
1.2 Wiring
CAUTION: Device wiring and commissioning can only be carried out by qualified
professionals. Always make the wirings while the power is switched off.
The terminals are designed for maximum of 1,5 mm2 cable area. Please note that the cables for
communication (RS‑485) should be twisted pair (2x2 pairs). The cable length to the room units should
not exceed 10 m.

1.3 Changing the room unit Modbus address
The room unit Modbus address is 1 as the factory setting. The address can be changed via Modbus or
by changing the address by turning the knob within 10 seconds after the room unit power is turned on.
Only addresses 1 and 2 are available when changing the address by turning the knob.
1. Turn on the room unit power.
All indicator lights are illuminated for 2 seconds to indicate that the lights are working.
After the 2 seconds, the current address is shown by flashing the left-most indicator lights. The
address is the same as the number of flashing indicator lights.

2. Turn the knob anytime within the 10 second time frame to change the address.
Address 1: Turn the knob three steps counter-clockwise and then three steps clockwise.
Address 2: Turn the knob three steps clockwise and then three steps counter-clockwise.
When the address is changed successfully, the indicator lights start to flash to show the current
address.

2 Maintenance
2.1 CO2 measurement calibration
The device uses automatic CO2 measurement calibration function (ABC algorithm). The function
eliminates the possible long term drift. The automatic calibration function can be used when the CO2
concentration drops at least two times within a week to the level of approximately 400 ppm. Therefore
the automatic calibration is effective in spaces that are not continuously occupied.
The automatic calibration function can be deactivated in continuously occupied spaces by using ML-SER
tool.
If the automatic calibration function is not in use, the device should be calibrated every 6-12 months.
The recommended calibration interval is 5 years even if the automatic calibration is in use.

B. Orange indicator lights
C. Set point knob
With the set point knob you can set the temperature set point for controller.
The indicator lights indicate how far the user set point is from the set point center (Modbus register
40002). When the user set point is same as the set point center value, one blue indicator light and
one orange indicator light are illuminated. When the set point knob is turned away from the set point
center, the corresponding lights are illuminated. When all blue or orange lights are illuminated the user
set point has reached the user set point range limit (Modbus register 40003). All indicator lights have
three states (off, dimmed, bright).
