● Automatically store data and will not lose data due to power failure.
Features
● Intelligent temperature control function: it can adjust the temperature by itself according to the environment change.
● Data storage security: with the ability to automatically store data, high data security.
● Convenient on-site operation: Supporting on-site operation, users can conveniently set the temperature, temperature correction value and timer on/off time.
● Wide adaptability: applicable to two-pipe or four-pipe fan coiler devices. It can be adapted to both two-wire and three-wire electric valves (solenoid valves), while the four-pipe fan coil unit is only adapted to two-wire electric valves.
● Flexible mode switching: cooling/heating mode can be switched manually.
● Self-adjustment of wind speed: it can be manually adjusted or automatically switched, so that the user can flexibly control the indoor airflow.
● Remote infrared control: Users can control the equipment from a distance and easily regulate various functions.
● Real-time status display: the product has a real-time status display function. The appearance of a specific logo in the main interface indicates that the air conditioner is on; without this logo, the air conditioner is off. If the main interface flashes, the communication is normal; if it does not flash, the communication is interrupted.

Installation Instructions
● Be sure to cut off the power and wait at least 5 minutes before proceeding with the installation operation, otherwise it may cause electric shock or damage the system components.
● The installation location should be on the wall of the indoor air-conditioning room, about 1.5m away from the ground, where the air is circulating, so as to ensure that the thermostat can accurately measure and control the room temperature.
● The thermostat must be installed in a place without sunlight, in a dry place or away from cooking equipment and other heat sources.
● Working environment temperature: 0°C ~ 50°C, relative humidity: <85% (24°C).
● Since the back seat of the thermostat needs to occupy part of the space of the junction box, it is recommended to use a multi-strand sheathed flexible wire with a specification of RVV 6 x 0.75 for wiring.
● During engineering installation, it is strictly forbidden to connect more than two fan coil units in parallel.
