B-LP-H
iSMA
iSMA-B-LP-H is a room unit with 2.3” LCD display and four function buttons. Additionally, the room unit has the built-in temperature and humidity sensors.
iSMA-B-LP-H 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. Thanks to built-in USB port, there is possibility to firmware update and room unit configuration without the necessity of power supply. iSMA-B-LP has the modern design and is available in different colours (white is basic) on client request.
