Quick Summary
The HTW-31-F17-2KS belongs to the Swan Controls series of Energy Saving Thermostats designed for fan coil units in 2-pipe heating and cooling HVAC systems. It manages a three-speed fan and a motorised valve through SPST output, supporting stable room temperature control. A remote contact allows heating and cooling changeover from the building system side. The thermostat also includes key-card logic to manage occupied and unoccupied conditions, helping hotels reduce unnecessary energy consumption.
This page explains the operating logic of these Energy Saving Thermostats, including control behaviour, installation wiring reference, key parameters for project confirmation, model code explanation and OEM/ODM possibilities. Typical project questions and answers are also provided for hotels deploying Energy Saving Thermostats in guest room HVAC systems.
Key Functional Highlights
(The core control functions and their practical value.)
(1) 2-pipe heating and cooling fan coil control
These Energy Saving Thermostats are built for fan coil applications that switch between heating and cooling through a central system schedule. The controller manages the fan and valve to maintain room comfort in hotel guest rooms.
(2) Remote heat/cool changeover for building control
The thermostat supports a remote contact for heating and cooling mode changeover. This allows facility teams to control seasonal operation from the plant side while maintaining simple room-level control.
(3) Flexible fan control logic for quiet operation
Two working modes can be selected during installer setup. Either the fan stops when the set-point is reached, or it continues running at low speed, helping reduce noise while maintaining temperature stability.
(4) Key-card based energy saving management
The keycard function allows the thermostat to detect occupancy. When the card is removed, the thermostat either stops the FCU or switches to an energy saving temperature set-point, supporting hotel energy management strategies.(If only need keycard function, click here)

Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
The HTW-31-F17-2KS belongs to Swan Controls Energy Saving Thermostats designed mainly for hotel guest rooms using fan coil HVAC systems. It works best in 2-pipe heating and cooling installations where occupancy-based energy management is required. In projects requiring complex building automation logic or full central override control, an additional building controller or BMS integration layer may be necessary.
Despite these limits mentioned above, ODM functional customisation can be discussed. Parameters such as energy saving temperature limits, keycard logic behaviour, display functions and control strategies can be reviewed based on project requirements.
OEM services are also supported, including OEM logo printing, colour options, customised labels and packaging design. These options help distributors and hotel solution providers maintain consistent branding while using reliable Energy Saving Thermostats.

Frequently Asked Questions
Q1. Can this thermostat be used in hotel guest rooms?
Yes. These Energy Saving Thermostats are designed for fan coil units commonly used in hotel HVAC systems.
Q2. How does the keycard energy saving function work?
When the keycard is removed, the thermostat switches to energy saving mode or stops the fan coil outputs depending on configuration.
Q3. Can heating and cooling mode be changed locally?
Heating and cooling changeover is normally controlled through the remote switch input connected to the building system.
Q4. What is the minimum order quantity and can I get samples?
Samples are available. The standard MOQ is about 300 units, but smaller quantities may be discussed.
Q5. How can I place an order?
Contact us with your requirements. We will issue a proforma invoice after confirmation. Payment methods include TT, PayPal and Visa.
Q6. How are the products shipped?
Express delivery usually takes about 7 days. Air freight also takes around 7 days, while sea freight takes about one month.
For hotel fan coil projects, an energy saving thermostat should not only control room temperature. It should also match the 2-pipe HVAC system, support reliable fan and valve control, and help manage occupied and unoccupied room conditions. The HTW-31-F17-2KS is suitable for hotels that need keycard-based energy saving, remote heat/cool changeover, and OEM-ready room control.
