Room thermostat with 2,6" LCD display, temperature and humidity sensors, 24V AC/DC Modbus RTU/ASCII, BACnet MSTP

iSMA-B-LP is a room unit with 2.3” LCD display and four function buttons. Additionally, the room unit has a built-in temperature, humidity (option) and CO2 (option) sensors.

There are four different built-in sensors combination available, depending on hardware version:
• iSMA-B-LP. Temperature sensor only.
• iSMA-B-LP-H. Temperature + Humidity sensors.
• iSMA-B-LP-C. Temperature + CO2 sensors.
• iSMA-B-LP-HC. Temperature + Humidity + CO2 sensors.

iSMA-B-LP is powered with 24 V AC/DC and has the built-in RS485 port (Modbus RTU/ASCII and BACnet MSTP). Use of open communication protocol allows to connect the room unit with any controller supporting Modbus RTU/ASCII or BACnet MSTP. Together with iSMA-B-FCU controller, the room unit allows to change the basic parameters such as: temperature setpoint, fan speed, FCU mode and others.
