E-Top provides a comprehensive range of fan coil unit solutions to meet diverse project needs. Our products support multiple control outputs and communication protocols, widely used in hotels, offices, apartments, schools, hospitals and commercial buildings.
Basic FCU Thermostat
The Basic Fan Coil Unit (FCU) Thermostat provides stable and cost-effective standalone control for traditional fan coil systems. Users can easily adjust the temperature, switch between heating and cooling modes, and select the fan speed. This thermostat supports on/off, 0-10V, and hybrid outputs, and is equipped with standard Digital Input (DI) and Analog Input (AI) interfaces for devices such as key cards, window cards, and external sensor etc.
Modbus FCU Thermostat
Modbus FCU thermostats are designed for building automation and central monitoring.With RS485 Modbus RTU communication, they can connect to BMS for centralized control and real-time status feedback, widely used in offices, commercial buildings and public projects.
BACnet MS/TP FCU Thermostat
For large-scale and high-standard building projects, BACnet MS/TP FCU thermostats are professional solutions.Compliant with standard BACnet protocol, it ensures stable and reliable integration with mainstream building management platforms.
WiFi Smart FCU Thermostat
E-Top provides WiFi smart FCU thermostats for mobile APP control.Users can remotely adjust temperature, switch mode and set schedule via APP, ideal for smart hotels, residences and apartments.
Here are some common problems and solutions
The Normal challenges of a fan coil thermostat & How we overcome these challenges
1.Malfunction in humid environment
Circuit board with moisture-proof and anti-corrosion coating, Replace with stainless steel screws.
2.Plastic shell aging and discoloration
High-quality ABS+PC plastics are selected for the shell, which is resistant to yellowing after long-term u
3.Sensor fault / Sensor selection error
Our thermostat supports sensor mode selection in the engineering menu: Internal, External, or I or E (Auto).
When set to I or E mode, if the remote sensor is disconnected, the thermostat automatically switches to the internal high-precision sensor.
When locked to External only, a sensor fault icon will be clearly displayed on the home screen for quick diagnosis.
4.Touch buttons not responsive
We use high-performance touch chips and anti-interference design. Each panel is strictly tested to ensure sensitive and stable operation.
5.Limited functions & poor compatibility with 9-pin terminal
Customers need to integrate multiple control functions, but standard 9-pin terminals restrict function expansion.
We adopt an optimized 14-pin terminal design to support flexible function customization, ensuring strong compatibility with various fan coil systems and diversified customer requirements.
