FAQ

  • Q Q1: Are you a manufacturer or a trading company?

    A
    We are a dedicated manufacturer with our own factory located in China,specializing in smart home IoT devices for over 10 years. Our product lines cover Tuya WiFi/Zigbee thermostats, IR remote controllers, and temperature/humidity sensors. We hold ISO 9001 quality certification and have obtained CE, RoHS, FCC, and ETL certifications for key products. Unlike trading companies, we control the entire production process — from PCB design and firmware development to final assembly and QA testing — which means faster lead times, more flexible customization, and direct factory pricing for our OEM/ODM partners.

  • Q Q2: What smart home platforms are your thermostats compatible with?

    A All our WiFi and Zigbee thermostats are built on the Tuya Smart platform,which provides native compatibility with Amazon Alexa, Google Home, Apple HomeKit (via Matter bridge), SmartThings, and IFTTT. Our products support both 2.4GHz WiFi and Zigbee 3.0 protocols. For B2B customers requiring private-label apps, we offer full SDK support through Tuya's OEM App solution — your brand name and logo appear in the app store, with no mention of Tuya or our company. We also support custom firmware for customers with their own cloud infrastructure.

  • Q Q3: What HVAC systems are your thermostats designed for?

    A Our thermostat range covers four major HVAC application types:
    - Fan Coil Units (FCU): 2-pipe and 4-pipe configurations, 0–10V and on/off valve control
    - Underfloor Heating: Electric and water/hydronic floor heating, NTC sensor compatible
    - Central Air Conditioning: Compatible with Mitsubishi Electric, Daikin,Fujitsu, Midea, Gree VRF/multi-split systems via IR or wired gateway
    - Heat Pump Systems: Heating + cooling mode, emergency heat support

    Each product page specifies the compatible system type. If you are unsure which model fits your project, send us your HVAC brand and model number and our technical team will recommend the correct thermostat within 24 hours.

  • Q Q4: What are your MOQ requirements for OEM/ODM orders?

    A Our MOQ policy is designed to be accessible for small and mid-size HVAC brands:

    Customization Type MOQ
    Standard product (no changes) 1 unit (sample order)
    Logo/brand printing 60 units
    Retail box & packaging design 1,200 units
    App UI / color theme customization 2,000 units
    Full ODM (custom hardware + firmware) Negotiable (typically 3,000–5,000units)

    For new brand partners, we recommend starting with a sample order of 1–5 units to verify product fit before committing to a branded run.
