Quick Summary
The HTW-WF08-2KE-LoRa room thermostat is designed for 2-pipe FCU systems. It controls a 3-speed fan and on/off valve for heating and cooling. It supports keycard input and external sensor function for control logic. LoRa communication enables stable data transmission across long distances in building systems.
This page explains how this room thermostat works in FCU control systems. It also covers key functions, control logic, and technical parameter confirmation. Typical questions and project considerations are included for reference. It helps guide selection and integration in LoRa-based building control projects.
Key Functional Highlights
(This section introduces the main control functions and their engineering value in the FCU system.)
(01) 3-speed fan control
Three fan speeds give simple airflow control during daily use. This helps match room temperature changes more smoothly. It also keeps the system quiet and reduces unnecessary energy use.
(02) 2-pipe (on/off)
This room thermostat works with standard 2-pipe FCU systems. It uses simple on/off valve control, which is easy to install and set up. This helps keep system control clear and reliable on site.
If the project requires 0-10V modulating valve control, one may refer to this model instead (please click → HTW-WF08-MKE-LoRa), which also supports LoRa.
(03) Keycard
The keycard function detects if the room is occupied or not. When the card is removed, the system can reduce or stop operation. This helps save energy and is useful in hotel projects. It also helps reduce unnecessary wear on system components over time.
(04) External sensor function
An external sensor can be added for better temperature measurement. It helps improve control in larger or uneven spaces. It can also be used to limit temperature for safer operation. This helps keep system performance stable under different room conditions.
(05) LoRa communication
LoRa allows long-distance communication with low power use. It works well in large buildings where wiring is not easy. This helps make system setup more flexible and stable. It also supports central monitoring across wide areas with fewer network nodes.

Project Fit & Customization
(This section describes project suitability, system limitations, and available customization options.)
This room thermostat is not suitable for 4-pipe systems or modulating valve control. It does not support BACnet or Modbus integration in this standard version. It may not fit projects that need fast real-time control through wired networks.
Despite these limitations mentioned above, function customisation can be discussed. LoRa communication can be changed or extended to other protocols if needed. Some control logic and interface changes can also be adjusted based on project needs.
OEM services are also supported for branding and appearance changes. Logo printing, colour changes, and label updates can be arranged. Packaging and simple interface changes can also be customised.
Certificates and Compliance
(This thermostat complies with European market requirements and is supported by certifications such as CE, RoHS, LVD test reports, EMC test reports, etc)
Exhibition Moments
(Our team regularly participates in international HVAC exhibitions such as Febrava in Brazil, The Big 5 in Dubai, and ISK-SODEX in Turkey, etc.)
Frequently Asked Questions
Q1: Can this room thermostat connect to a BMS system?
This model uses LoRa instead of standard BMS protocols. It does not directly support Modbus or BACnet. A gateway may be needed for integration.
Q2: What is the use of the external sensor?
The external sensor gives an extra temperature reading point. It helps improve control in larger spaces. It can also support temperature limit settings.
Q3: Is the keycard function suitable for hotels?
Yes, it is designed for hotel energy saving use. The system reduces operation when the room is empty. This helps lower running cost.
Q4: Why use LoRa in HVAC systems?
LoRa supports long-distance communication with low power use. It reduces wiring work in large buildings. It is useful for retrofit or wide-area projects.
Q5: What is the MOQ and do you support samples?
We support sample orders for testing. Standard MOQ is 300 units. Smaller quantities like 100 units can be discussed.
Q6: How can we place an order and arrange shipping?
Contact us to confirm details and receive a PI. Payment supports TT, PayPal, and Visa. Terms include EXW, FOB, and DAP.
Q7: How long does production take?
Samples ship within 7 days if no customisation is needed. Custom orders usually take 3–5 weeks. Bulk orders around 300 units take about one month.
Q8: What shipping methods are available?
Express delivery takes about 7 days. Air freight also takes around 7 days. Sea shipping usually takes about one month.
