iSMA-B-LP/LP-1

The iSMA-B-LP is a wall panel   with a 2.3” LCD display and four function buttons. In addition, the panel has a built-in temperature sensor and optional humidity and CO2 sensors.
 
The iSMA-B-LP can be operated from a 24 V AC/DC power supply and has a built-in RS485 port (Modbus RTU/ASCII, BACnet MSTP). The open communication protocol allows the panel to be connected to any controller that supports Modbus RTU/ASCII or BACnet MSTP communication.
 
Together with the iSMA-B-FCU controller, the panel allows you to change basic parameters: temperature setpoint, fan speed, FCU mode and others. Thanks to the built-in USB port, it is possible to maintain the configuration of the panel without power supply.
 
The iSMA-B-LP has a modern appearance and is available in two different colors according to the customer's request, as well as two versions for the appearance of the button icons.

Main features:

  • 2.3" LCD display with backlight

  • 4 function keys

  • Built-in temperature, optional CO2 and humidity sensor

  • Modbus RTU/ASCII

  • BACnet MSTP

  • More than 100 freely configurable variables

  • Option to display current time
