4-Pipe Room Thermostat with Keycard for Hotel Accurate Sensing

Key Functional Highlights

(This section explains the core control functions and their practical value.)

(01) 3-Speed Fan Control
The 3-speed fan adjusts airflow to match room temperature changes. It ensures quick response, improves comfort, and reduces energy consumption in hotel FCU systems.

(02) 4-Pipe On/Off Valve Control
This thermostat controls 4-pipe on/off valves precisely for both heating and cooling. Stable cycles avoid temperature overshoot and ensure reliable hotel room comfort.

For 2-pipe model with keycard feature, please refer to this model (HTW-WF11-FC-2K).

(03) Keycard Integration
Keycard disables HVAC when rooms are unoccupied. This prevents energy waste and aligns with hotel energy management strategies.

(04) Energy Saving Mode
Energy-saving mode optimises fan and valve operation based on occupancy and set-point. It balances comfort and efficiency, reducing operational costs.

Project Fit & Customization

(This section explains where the product can be used, its limits, and OEM/ODM options.)
HTW-WF11-FC-4K is designed for standalone hotel FCU applications. It is unsuitable for BMS integration requiring modulating valve control or high-humidity environments.

Despite these limits, ODM customization is supported. Firmware behaviour, keycard response, and energy-saving parameters can be tailored for specific projects. Discussion with our engineers ensures correct deployment.

OEM customization is available, including logo printing, colour adjustments, and labelling, making this room thermostat suitable for branded hotel deployments.
