HB403A-SRT80Y Electric Thermostat for FCU with AC Motor

SRT series thermostats are widely used in the indoor temperature control and adjustment of heating and cooling in HVAC system in commercial, industrial and civil buildings, especially for control systems such as DC fan coil units and electric heaters. These thermostats are electronic temperature controller with large-screen liquid crystal display. With RS485 communication function, they could realize remote reading, parameter modification and remote control function.
The SRT80Y adopts a simple and stylish design with smooth lines, and the panel is made of high-quality materials with a superior texture, which can be better integrated into the interior environment of various decoration styles. The display is large and clear, and the parameters can be seen at a glance. The operating buttons are well laid out and feel comfortable, making it easy for users to operate.

With intelligent temperature control function.

 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.
