The Honeywell thermostat is an advanced and configurable thermostat designed for commercial buildings. It supports building automation with flexible inputs/outputs that meet the needs of most fan coil unit applications. It can therefore control both 2-pipe and 4-pipe systems. It includes dehumidification functions with heating, auxiliary heating functions, and quick seasonal mode change for 2-pipe systems.

The device supports BACnet MS/TP and Modbus communication via the RS485 bus, which is typical for HVAC systems. This bus is also used for future firmware updates and functionality expansion. Intelligent control and scheduling algorithms help achieve an optimal balance between energy efficiency and comfort.
