Driven by the dual drive of building intelligence and green energy saving, precise control of HVAC systems has become the key to improving indoor comfort and reducing energy consumption. E-TOP has been deeply involved in the field of temperature control equipment for 19 years, integrating industrial-grade control technology and IoT communication capabilities, and launching a full range of floor heating and fan coil thermostat products, covering electric/water floor heating, fan coils and other terminal devices. With multi-protocol compatibility, intelligent algorithm optimization and scenario-based adaptation design, it provides one-stop solutions from single-point control to system-level linkage for residential, commercial and industrial scenarios, helping to build an efficient, comfortable and intelligent modern HVAC ecosystem.

Product category introduction —— Accurately adapt to the needs of different terminal devices

Floor heating and fan coil thermostat (special for floor heating)
Core positioning: energy-saving center of electric/water floor heating system
Technical features:
Dual temperature monitoring: support real-time dual measurement of ground temperature (NTC sensor, accuracy ±0.5℃) and ambient temperature (thermocouple, accuracy ±1℃) to prevent overheating risks;
Load compatibility: 16A relay output (support 3.5kW electric floor heating)/24V valve control output (adapt to water floor heating electric valve), compatible with various floor heating types such as carbon fiber, cable, capillary, etc.;
Communication capability: Modbus RTU (RS485)/WiFi 2.4G (optional), support BACnet MS/TP protocol customization.
Core functions:
Intelligent energy saving: 7 days × 4 time periods programmable, with “preheating algorithm” to start 30 minutes in advance to avoid temperature lag;
Safety protection: automatic power off in case of over-temperature (threshold 50℃~80℃ adjustable) + leakage protection (response time <0.1 second), passed UL 943 electric heating safety certification;
Interactive design: 3.5-inch LCD screen (with backlight), supports Chinese/English menus, compatible with wall concealed installation (86-type bottom box) and guide rail installation.

Floor heating and fan coil thermostat (fan coil dedicated type)
Core positioning: intelligent terminal at the end of central air conditioning
Technical features:
Three-speed fan control: supports manual adjustment of high/medium/low wind speed or automatic mode (intelligent switching according to temperature difference), wind speed switching noise <35dB;
Mode integration: cooling/heating/ventilation/automatic four modes, compatible with two-pipe/four-pipe system, supports 0-10V analog output (adaptive electric valve);
Communication capability: BACnet MS/TP (wired)/Zigbee 3.0 (wireless), supports real-time data interaction with building automation (BAS) system.
Core functions:
Humidity linkage: external humidity sensor (accuracy ±3% RH), automatic start and stop of dehumidification function, maintaining indoor humidity in a comfortable range of 40%-60%;
Occupancy detection: linked with door and window sensors/infrared probes, automatically switching to energy-saving mode when no one is detected, reducing energy consumption by 30%+;
Fault diagnosis: real-time display of abnormal conditions such as fan overload and valve jamming, and support for remote fault code push.

Core technical advantages – full terminal coverage, intelligence, high reliability

Multi-scenario adaptation capability
Floor heating exclusive: built-in “heat flow delay compensation algorithm”, automatically adjusts the heating curve according to the thickness of the insulation layer, and improves the heating efficiency by 20%;
Fan coil exclusive: “wind speed-temperature difference dynamic matching model” to avoid energy waste caused by high wind speed and low load operation, and energy saving rate of 25%.
Full-protocol interoperability ecosystem
Supports mainstream protocols such as Modbus, BACnet, Zigbee, KNX, and provides protocol conversion gateways (optional) to achieve cross-system linkage of devices of different brands;
The fan coil thermostat is compatible with the Matter smart home standard and can be connected to Apple HomeKit and Huawei Hongmeng ecosystem in the future.
