Quick Summary
The HTW-WF11-FC-2W house thermostat is designed for 2-pipe fan coil units with 3-speed fan control and on/off valve output. It operates in both cooling and heating modes, powered by 95~240Vac. Programming, energy-saving mode and Wi-Fi control support stable temperature regulation and flexible room management.
This page explains how this house thermostat works within a fan coil system, what control logic it applies, key specifications for engineering confirmation, and typical installation or deployment considerations for projects.
Key Functional Highlights
(01) 3-speed fan and on/off valve control
This house thermostat controls 3 fan speeds and a 2-pipe on/off valve. This ensures balanced airflow and water flow, reducing temperature fluctuation in daily operation.
(02) Programmable Operation
Built-in scheduling allows automatic switching between operating periods. This helps projects reduce manual adjustment and improve overall energy efficiency.
(03) Energy-Saving Mode Logic
When activated, the thermostat adjusts control behaviour to limit unnecessary fan and valve action, supporting long-term operational cost control.
(04) Wi-Fi Connectivity
This Wifi thermostat supports App and voice control, allowing remote adjustment and monitoring. This is practical for residential projects and small commercial deployments requiring flexible access.

Project Fit & Customisation
This house thermostat is suitable for standard 2-pipe fan coil systems. It is not intended for 4-pipe configurations or projects that require advanced BMS integration beyond Wi-Fi communication. Applications needing modulating-only valve control or complex central logic should consider other models.
Despite these limits mentioned above, functional customisation can be discussed. ODM support may include adjusted control logic, predefined parameter settings, or communication options based on project structure. Feasibility depends on electrical layout and system compatibility, and should be evaluated before confirmation.
OEM customisation is also available, including logo printing, colour adjustment and customised labels. Packaging modification can be discussed for bulk orders.
Frequently Asked Questions
1- Can the HTW-WF11-FC-2W wifi thermostat control different fan speeds and valve types?
This house thermostat supports 3-speed fan control and a 2-pipe on/off valve only for standard fan coil units, ensuring proper temperature regulation.
2- Which installation boxes are compatible with this house thermostat?
It is compatible with EU round or standard 86×86 mm boxes, suitable for flush mounting in most indoor fan coil installations, or for surface mounting when paired with a surface-mounted box.
3- Can it be integrated with building management systems (BMS)?
This Wifi thermostat supports Wi-Fi communication, enabling group control. However, it does not support BMS protocols such as Modbus or BACnet. Please feel free to contact us for alternative recommendations.
4- What is the minimum order quantity and sample availability?
Samples are available. Standard MOQ is 300 units, but smaller quantities can be discussed for testing or pilot projects.
5- How can I place an order?
Contact us to confirm your requirements, then a proforma invoice will be issued. TT, PayPal, Visa, etc supported. Terms include EXW, FOB, DAP and more.
6- How is shipping handled?
Courier delivery takes around seven days. Air shipping also takes seven days. Sea shipping requires approximately one month, depending on the situation.
