LP 1 top 1

Wall panel with 2.3" LCD display, control buttons, temperature and humidity sensor. Available in two button versions: for FCU and custom applications.

Intuitive Management
The LP panels interact with a user with a 2.3” LCD that indicates the working status of the device and shows the real-time measurements from sensors. Four function buttons allow for setting the desired parameters.

Unlimited Configuration Possibilities
The LP panel is equipped with a special set of Modbus registers and BACnet objects that can be used by the user to freely control lights, blinds, alarms, and set occupancy statuses that come from the BMS system, with the possibility of displaying statuses with the display icons.

Ease of Installation and Configuration
Suitable for surface and flush mounting, the LP panel offers an effortless configuration using network protocols or a built-in USB port, even without an external power supply.

Multiprotocol interface
The LP panel is factory-equipped with the two most popular open communication protocols, Modbus and BACnet, which are selectable using a DIP switch.

Ultimate flexibility
The LP panels are available in two body colors, black or white, and with a set of temperature, CO2, and humidity sensors in different configurations, depending on the selected model. The iSMA-B-LP-H version is equipped with temperature and humidity sensors.
