0-10V Output Hotel Room Fan Coil Thermostat with Keycard Energy Efficient

Key Functional Highlights

(This section introduces the main control functions and their engineering value in the specific fan coil thermostat system.)

(01) 3-speed fan control
This function adjusts airflow based on room demand. It helps keep comfort stable across different load conditions. It also reduces noise and unnecessary fan operation during partial load.

(02) 2-pipe 0–10V valve control
This fan coil thermostat sends a modulating signal to the valve. This allows smoother temperature control than simple on/off systems. It helps avoid frequent switching and improves overall energy efficiency.

(03) Remote setback via keycard
The thermostat detects a keycard signal from the hotel room. When the card is removed, it shifts to a setback temperature. This helps reduce energy use in unoccupied rooms, which is very useful for hotel management.

(04) Energy-saving mode
This mode reduces output during low-demand periods. It avoids unnecessary heating or cooling. Over time, it helps improve system efficiency and lowers operating costs.

(05) Set-point limitation
This function limits the temperature range users can select. It prevents extreme settings that may affect system balance. This is useful in public or shared environments.

If the project requires integration with a building automation system, one may consider this BACnet model instead (please click → HTW-WF11-FC-MKB).

Model Code Guide

(This section explains what configuration the model code refers to in this fan coil thermostat series.)

Fan coil series	xx stands for
EC	EC fan
2/4	2 for 2-pipe on/off; 4 for 4-pipe on/off system
M	Modulating valve control
W	Wi-Fi
N/B	N for Modbus; B for BACnet
K/E	K for Keycard; E for External sensor
24	Powered by 24V, or with 24V output for 0-10V valve
Example HTW-WF11-FC-xx: if xx = 2EN, it stands for a 3-speed fan, 2-pipe system with on/off valve control, external sensor function, and Modbus communication. Most sub-models are ready-made. Kindly contact us to confirm availability.

Project Fit & Customisation

(This section describes project suitability, system limitations, and available customisation options.)

This model is not suitable for 4-pipe FCU systems or on/off valve control. It does not support BMS protocols like Modbus or BACnet. It is also not designed for EC fan applications or complex central control systems.

Despite these limitations mentioned above, some functions can be customised. Communication options like Modbus or BACnet may be evaluated. Additional sensors or control logic can also be discussed based on the project.

OEM customisation is also available for branding needs. Logo printing, housing colour, and labels can be adjusted. Packaging can also be tailored for your market requirements.

Certificates and Compliance

(This thermostat complies with European market requirements and is supported by certifications such as CE, RoHS, LVD test reports, EMC test reports, etc)

Exhibition Moments

(Our team regularly participates in international HVAC exhibitions such as Febrava in Brazil, The Big 5 in Dubai, and ISK-SODEX in Turkey, etc.)

Frequently Asked Questions

Q1: Can this thermostat be used in a 4-pipe FCU system?

No, this fan coil thermostat is designed for 2-pipe systems only. It does not control separate heating and cooling valves. For 4-pipe projects, a different model is required.

Q2: Does it support BMS integration?

This version works as a standalone fan coil thermostat. It does not include communication protocols. For BMS use, models with Modbus or BACnet are recommended.

Q3: How does the 0–10V valve control help in real use?

The valve opening is adjusted gradually instead of switching on and off. This keeps the room temperature more stable. It also reduces energy waste during operation.

Q4: How does the keycard function work in practice?

The thermostat receives a signal from the room keycard system. When the room is empty, it switches to setback mode. This helps reduce unnecessary energy use.

Q5: What is the MOQ and can we get samples?

We support sample orders for testing and evaluation. Standard MOQ is 300 units. Smaller quantities, such as 100 units, can be discussed.

Q6: How do we place an order?

Please contact us with your requirements. We will confirm details and issue a PI. Payment can be made by TT, PayPal, or Visa.

Q7: How long does it take to prepare products?

Standard samples are ready within 7 days. Custom orders usually take 3–5 weeks. Bulk orders, such as 300 units, take about one month.

Q8: How will the goods be shipped?

Courier delivery usually takes about 7 days to your door. Air freight has a similar timeline. Sea shipping typically takes around one month.
