Keycard HVAC Thermostat 2 Pipe 4 Pipe Practical for Hotel Clear Reading

Key Functional Highlights

(This section introduces the main control functions and their engineering value in this fan coil application.)

(01) 3-speed fan control
Three fan speeds help the room respond better to changing demand. This gives more stable comfort during daily use. It also helps site teams balance airflow, noise, and energy use more easily. This function supports smoother operation during peak and off-peak periods.

(02) 2/4 pipe (on/off valve control)
This series includes two sub-models for different pipe systems. The 2K version suits a 2-pipe fan coil layout. The 4K version suits a 4-pipe layout and supports separate heating and cooling valve control. This helps match the correct system design without extra wiring changes.

(03) Keycard for hotel
The keycard function is useful in hotel guest rooms. When the card is removed, the system can reduce or stop operation. This helps cut wasted energy and supports simpler room management. It also reduces manual checks for housekeeping and maintenance teams.

BACnet models with the same design are also available in this series. If one is interested, please refer to this model (please click → HTW-31-F10-2B/4B).

(04) White (positive display) or Black (negative display)
Two screen styles make project matching easier. The white display looks bright and clear in many interiors. The black display gives a stronger modern look and is easy to recognise in hotel projects. This also helps align with different room design standards.

Project Fit & Customization

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

This model is not for modulating valve projects. It is also not suitable for BMS jobs that need Modbus or BACnet. App control and remote platform control are not included in this standard version.

Despite these limits, some functions may still be discussed for ODM projects. For example, communication, sensor input, or other control changes may be considered. Final support depends on system logic, quantity, and project timing.

OEM custom work is also available for brand-based projects. We may discuss logo printing, label changes, and colour matching. This is often helpful for hotel groups, distributors, and local HVAC thermostat suppliers.

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: Is HTW-31-F10-2K/4K suitable for both heating and cooling fan coil systems?

Yes, but the exact use depends on the sub-model. The 2K version is for 2-pipe systems. The 4K version is for 4-pipe systems with separate control logic.

Q2: Does this HVAC thermostat support an external sensor?

The standard information provided here shows a built-in sensor only. An external sensor is not listed as standard. If your project needs it, we can discuss related options.

Q3: Can this model connect to a BMS system?

This standard version is mainly for local room control. It does not include Modbus or BACnet as listed here. For BMS projects, another model is usually the better choice.

Q4: Why is keycard useful in a hotel project?

Keycard helps reduce operation when the room is not occupied. This is useful in hotel energy management. It can also make room control more practical for daily operation.

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

Yes, we support samples for checking and testing. The usual MOQ is 300 units. Smaller trial orders, such as 100 units, may also be discussed.

Q6: How do we place an order and what payment terms do you support?

Please contact us with your requirements first. We will confirm the details and then provide a PI. Payment can support TT, PayPal, Visa, and terms such as EXW, FOB, and DAP.

Q7: How long does it take to prepare the products?

Standard non-custom samples are usually sent within 7 days. Custom work needs review, programming changes, and project checking. For around 300 units, production usually needs about one month.

Q8: How are the goods usually shipped?

Courier is often the first choice for samples and urgent orders. Door-to-door delivery by FedEx, DHL, or UPS is often about 7 days. Air freight or sea freight may also be arranged depending on quantity and destination.
