Quick Summary
The HTW-31-F17-2K is designed as one of Swan Controls Hotel Thermostats for indoor fan coil units in 2-pipe heating/cooling HVAC systems. It controls a 3-speed fan with on/off outputs and manages operation based on occupied or unoccupied status through a keycard contact. When the keycard contact is open, the fan coil stops and the valve closes, helping reduce unnecessary energy use in guest rooms. A power-off memory function restores the last settings after power returns, supporting stable daily operation.

Key Functional Highlights
(This section explains the core control functions and their practical value.)
(1) 2-pipe heating/cooling control for guest room FCU
These Hotel Thermostats are suited to 2-pipe fan coil applications that switch between heating and cooling by season or system schedule. It supports stable room comfort control with clear commissioning logic.(Standalone version please refer here)
(2) Keycard contact for occupied/unoccupied energy control
In hotel projects, the keycard function helps reduce unnecessary run time. When the contact is open, the fan-coil stops and the valve closes, aligning HVAC operation with room occupancy.
(3) Fan speed logic options for smoother operation
The controller offers two fan speed control solutions selectable in ISU. This supports different hotel standards, balancing comfort and noise management while keeping operation simple for staff.
(4) Clear display behaviour for daily guest use
The screen shows set-point by default and can display room temperature after setting. This supports simple guest operation and reduces front-desk complaints caused by unclear thermostat feedback.

Guide
(This section explains what configuration the model code refers to.)
| Fan coil series | xx stands for |
|---|---|
| 2/4 | 2 for 2-pipe on/off; 4 for 4-pipe on/off system |
| W | Wi-Fi |
| N | N for Modbus |
| K/E | K for Keycard; E for External sensor |
| Example HHTW-31-F17-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 & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
In hotel guest rooms, Hotel Thermostats are often required to balance comfort, energy use, and easy operation. The HTW-31-F17-2K is suitable for 2-pipe heating/cooling fan coil units where occupancy-based control is needed. It is not the best fit for projects that require full room automation logic beyond HVAC, or strict central control where local settings must be overridden at all times. If the hotel requires deeper BMS strategies, a gateway or a higher-level controller should be considered in the architecture.
Despite these limits mentioned above, we can support ODM by discussion. For example, keycard contact logic, display wording, parameter range adjustment, and control behaviour details can be reviewed based on hotel standards and commissioning processes. The goal is to keep Hotel Thermostats stable for daily guest use and simple for maintenance teams.
OEM support is available, including OEM logo printing, colour customisation, label changes, and packaging adjustments. These options help hotel projects and distributors build a consistent supply identity while using a proven platform of Hotel Thermostats.

Frequently Asked Questions
Q1. Is this thermostat suitable for all hotel fan coil rooms?
This model is designed for 2-pipe heating/cooling fan coil units. Please confirm fan wiring, seasonal changeover method, and keycard contact type before deployment.
Q2. How does the keycard function work in daily operation?
When the keycard contact is open, the fan-coil stops and the valve closes. When occupied, the system can resume operation based on settings.
Q3. Which fan speed control option should I choose in ISU?
For most hotel rooms, the default 3-speed solution is common. The 1-speed (low only) option may fit projects focusing on noise control and simpler operation.
Q4. What is the minimum order quantity and can I get samples?
Samples are available. The usual MOQ is 300 units, and smaller quantities may be discussed depending on your project plan.
Q5. How can I place an order?
Please contact us to confirm requirements. We will provide a proforma invoice. Payment supports TT, PayPal, Visa, etc., with terms such as EXW, FOB, DAP and more.
Q6. How do you ship the goods?
We usually recommend express door-to-door service, around 7 days. Air freight is also about 7 days. Sea freight usually takes one month or longer.
For hotel fan coil projects, a thermostat should do more than basic temperature control. It should match the 2-pipe HVAC system, support stable fan and valve output, and work clearly with the room keycard contact. The HTW-31-F17-2K is suitable for hotels that need simple guest operation, occupancy-based energy saving, and OEM-ready thermostat supply.
