Project Fit & Customisation
This section helps buyers confirm whether this thermostat with keycard fits the project scope before discussing ODM or OEM options.
This model is not suitable for projects that require built-in BMS communication, WiFi connection, App control, or remote cloud management as standard. It is also not the right choice for systems that need 4-pipe control, EC fan 0–10V output, external sensor logic, or advanced centralised control without further function changes.
Despite these limitations mentioned above, ODM function customisation can be discussed based on project needs and order quantity. For example, WiFi, Modbus, BACnet, external sensor support, 4-pipe control, or different control logic may be developed or adjusted on a suitable product platform.
OEM customisation is also available for brand and market needs. Options may include OEM logo printing, colour customisation, private label, packaging design, user manual adjustment, and model code labelling. These details can be discussed according to the target market, quantity, and project requirements.

Frequently Asked Questions
Q1: Is this model suitable for a 2-pipe fan coil system?
Yes. This model is designed for 2-pipe fan coil applications. It can control heating and cooling in one water loop, making it a practical choice for standard hotel room FCU projects.
Q2: Can this thermostat connect to BMS or central control systems?
This standard version is a standalone thermostat, so it does not include BMS communication by default. If your project needs Modbus, BACnet, or other communication functions, please feel free to get in touch with us to discuss a suitable customized version.
Q3: Does this model support external sensors?
The standard configuration does not include external sensor control. For projects that need remote temperature sensing, floor sensing, or special sensor logic, we can review the system requirements and check whether ODM function customization is suitable.
Q4: Can this model be customized for hotel projects?
Yes, project customization can be discussed. Depending on quantity and technical requirements, we can review options such as keycard logic, control settings, interface details, WiFi, communication protocol, or other suitable function adjustments. This thermostat with keycard can also be reviewed for different room management requirements.
Q5: What is the MOQ and can I get samples?
Yes, we support samples for testing. The usual MOQ is 300 units, but smaller trial orders, such as 100 units, can also be discussed for project evaluation.
Q6: How can I place an order and arrange shipping?
Please feel free to get in touch with us and share your project requirements first. After confirming the model, quantity, and delivery details, we will provide a PI. Payment can be arranged by TT, PayPal, Visa, and other agreed methods. Trade terms such as EXW, FOB, and DAP are available.
Q7: How long does it take to prepare the products?
Non-customized samples can usually be sent within 7 days. If customization is required, we need to evaluate the quantity, function changes, and software adjustment first. Custom projects usually take about 3–5 weeks. For a standard bulk order of around 300 units, preparation normally takes about one month.
Q8: What shipping methods are available?
For samples and small orders, we usually recommend door-to-door courier service such as FedEx, DHL, or UPS, which often takes about 7 days. Air freight may also take around 7 days, while sea shipping usually takes about one month or longer. The best option depends on order size, destination, and delivery schedule.
