Tuya App Control Programmable Thermostat WiFi 2 pipe Easy to Use

Key Functional Highlights

(This section introduces the main control functions and their practical value in a fan coil system using a WiFi programmable thermostat.)

(01) 3-speed fan control
The thermostat supports low, medium, and high fan speeds. This helps match airflow to different room conditions. It keeps the room comfortable while avoiding unnecessary energy use. We can also set the fan speed manually or let it run automatically.

(02) 2 pipe (on/off valve control)
This model is made for standard 2-pipe fan coil systems. The valve is either fully on or fully off. This simple control helps keep the system stable and easy to manage. We can rely on this logic for easy setup and smooth daily operation.

(03) Programmable setting
The programmable thermostat allows time-based temperature settings. It can lower energy use when the room is empty. This helps keep daily operations simple and efficient. We can adjust schedules based on different daily routines.

(04) WiFi (app control)
With WiFi, the thermostat can be controlled by a mobile app. We can adjust settings from anywhere. This is helpful for both home use and property management. We can also monitor and manage multiple rooms more easily.

If one is looking for the BACnet communication for the building management system, one may refer to these two models instead (please click → HTW-F10-2B/4B).

(05) Child Lock

This thermostat also comes with a child lock feature, which helps to prevent unwanted settings in some situations. It can avoid accidental changes from children or public use. We can keep the settings stable without frequent adjustment.

Project Fit & Customization

(This section describes project suitability, system limitations, and available customization options.)

This model is not suitable for projects needing BMS connection. It does not support Modbus or BACnet by default. It also does not support modulating valve control. Projects needing central control should consider other models.

Despite these limits, some changes can be discussed. WiFi settings or app functions may be adjusted if needed. Other small changes may also be possible based on the project. Final options depend on quantity and technical review.

OEM service is available for branding and appearance. Logo printing and label changes can be arranged. Packaging and colour options can also be discussed if required.

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 thermostat connect to a BMS system?

This model does not support BMS protocols. It is made for standalone or WiFi use. For BMS, other models are recommended. We can suggest suitable alternatives if needed.

Q2: Does it support an external sensor?

This version uses a built-in sensor only. An external sensor is not included by default. Custom options may be discussed if needed. We can review project needs and advise accordingly.

Q3: Can it handle both heating and cooling?

Yes, it supports both modes. It works with a shared 2-pipe system. The switching is stable and automatic. We can help confirm system compatibility before ordering.

Q4: Is the programmable function easy to use?

Yes, the programmable thermostat is simple to set. Users can adjust time and temperature easily. It helps reduce manual changes. We can also provide a quick guide if required.

Q5: What is the MOQ and can we get samples?

We support sample orders for testing and evaluation. Standard MOQ is 300 units. Smaller trial quantities, like 100 units, may be discussed.

Q6: How do we place an order?

Please contact us with your requirements. We will confirm details and provide a PI. Payment supports TT, PayPal, and Visa. We will guide you through each step clearly.

Q7: How long does it take to prepare?

Standard samples are ready within 7 days. Custom orders need more time for setup. Bulk orders usually take about one month. We will confirm the timeline before production starts.

Q8: How will the goods be shipped?

Courier delivery takes about 7 days to door. Air shipping is similar in timing. Sea shipping takes about one month, depending on location. We can suggest the best option based on urgency.
