                  ST-109 LCD Thermostat

                       ST-109  LCD Room Thermostat, adopting international advanced microcomputer chip control technology, is used for temperature control of central air-conditioning fan coil units system and air hose system. By comparing the room temperature with the set temperature, then we can control the open and close of the electric control valve and electric ball valve for the fan coil at the terminal air conditioning. In this way, the room temperature can stay at a stable range.
