Whole-home climate control from one screen.
The Aqara Thermostat W400 is a wall-mounted smart thermostat with a 4-inch touchscreen, built to run VRF and FCU climate systems. It replaces the basic wall controller on your air conditioning with a panel that also drives the rest of your smart home — lighting, window coverings and scenes — so one point on the wall does the work of several.
Finished in grey, with a glass front panel over a flame-retardant ABS body.
Features:
-
Built for VRF and FCU Systems: Designed specifically for variable refrigerant flow and fan coil unit installations — the W400 (WT-A01D) is the VRF model.
-
Matter Certified: Certified to the Matter smart home standard, so it works across major platforms and stays compatible as your setup grows.
-
4-Inch Touchscreen: A clear, responsive display that anyone in the house can use without instructions.
-
Triple Wireless: Wi-Fi (2.4GHz / 5GHz), Zigbee and Bluetooth on board. No hub is needed for Wi-Fi operation, though an Aqara hub is recommended if you are adding Zigbee sub-devices.
-
Zigbee Network Repeater: Acts as a repeater to extend and strengthen your Zigbee mesh as you add devices.
-
More Than a Thermostat: Control connected lights and curtains, and trigger scene automations directly from the panel.
-
Fully Customisable Interface: Six configurable pages and ten styling options, so the screen shows what your household actually uses.
-
Mains Powered: Runs on 220–250V AC, 50/60Hz — wired in during installation, no batteries to change.
