1. Main Function

This series of thermostats supports two-pipe, four-pipe, and dual-supply systems for fan coil

units, and is used for temperature control in water or air systems. By using touch buttons,

users can select the desired mode and set the required temperature and fan speed. The

thermostat compares the ambient temperature with the set temperature to control the

operation of the fan coil unit, electric valve, electric ball valve, or electric damper, achieving

both comfort and energy efficiency.
