JustCare currently offers the Aqara W400 Thermostat and Aqara Smart Thermostat S3. These models are designed for different climate-control requirements, so the existing AC or HVAC system should be checked before choosing a thermostat.
Aqara’s current climate-control ecosystem includes dedicated thermostat and HVAC controllers for applications such as fan coil units, VRF systems and other supported climate-control equipment. :contentReference[oaicite:1]{index=1}
| Model | Best For | Key Features |
|---|---|---|
| Aqara W400 Thermostat | Modern FCU climate control and smart-home integration | Touchscreen, WiFi, Zigbee, Bluetooth, Aqara Home control and compatible FCU configurations |
| Aqara Smart Thermostat S3 | Zigbee-based smart climate control | 3.95-inch touchscreen, temperature and humidity sensing, Aqara Home integration and compatible HVAC/FCU control |
The Aqara W400 Thermostat is the newer and more advanced option in JustCare’s current Aqara thermostat range.
The W400 combines a modern touchscreen with WiFi, Zigbee and Bluetooth connectivity. Depending on the specific W400 variant, it is designed for compatible climate-control applications including fan coil unit and VRF systems.
For the FCU version available from JustCare, the thermostat is suitable for compatible 2-pipe and 4-pipe fan coil systems and can provide temperature, mode and fan control through its touchscreen and supported smart functions.
Aqara officially describes the W400 as a whole-home climate-control product and lists separate W400 FCU and VRF variants in its current device ecosystem. :contentReference[oaicite:2]{index=2}
The Aqara Smart Thermostat S3 is a Zigbee-based touchscreen thermostat designed for compatible climate-control systems.
The S3 features a 3.95-inch touchscreen together with built-in temperature and humidity sensing. It can connect through a compatible Aqara Zigbee gateway for Aqara Home app control and supported smart-home automation.
Depending on the installation configuration, the S3 is designed for selected fan coil, central air-conditioning, water floor-heating and fresh-air control applications. Because the S3 is a region-specific Aqara product, gateway, app-region and system compatibility should be confirmed before purchase.
The right Aqara thermostat depends primarily on the AC system you need to control.
Choose the Aqara W400 if you want a newer touchscreen climate controller with direct WiFi plus Zigbee connectivity and your property uses a compatible W400-supported FCU or other matching system.
Consider the Aqara S3 if you already use a compatible Aqara Zigbee ecosystem and your HVAC configuration matches the S3’s supported control requirements.
For UAE properties, system compatibility should take priority over choosing a thermostat only by appearance or smart-home features.
Fan coil units are common in UAE apartments, hotels, offices and commercial buildings. Aqara offers thermostat options designed specifically for compatible FCU climate control.
The Aqara W400 FCU available from JustCare is designed for compatible 2-pipe and 4-pipe fan coil systems. Aqara’s current documentation identifies W400 FCU as a dedicated climate-control device. :contentReference[oaicite:3]{index=3}
However, not every FCU uses the same wiring or control logic. Before replacing an existing thermostat, check:
The W400 is particularly relevant to the UAE market because compatible fan coil systems are widely used in residential and commercial buildings.
The FCU model listed by JustCare uses a 220–250V AC power supply and is designed around compatible 2-pipe and 4-pipe FCU control. This differs from products such as Nest and Ecobee thermostats that are primarily designed around conventional low-voltage 24V HVAC wiring.
This means an Aqara W400 may be a more direct smart-control option for certain compatible FCU installations, although the existing wiring and valve configuration still need to be checked.
Aqara thermostats replace basic wall controls with a more modern touchscreen interface.
Depending on the model and system configuration, users can manage functions such as temperature, operating mode, fan settings and smart scenes directly from the wall display.
The W400 can also work as part of a wider Aqara smart-home setup, allowing supported devices and automation scenes to be accessed from the thermostat interface.
Compatible Aqara thermostat models can connect with the Aqara Home ecosystem for supported remote controls, schedules and automations.
For example, an Aqara thermostat can become part of a smart scene that coordinates climate control with compatible sensors, switches, curtains or other connected devices.
Available functions depend on the thermostat model, gateway requirements, device region and other products used in the Aqara ecosystem.
The Aqara W400 supports WiFi, Zigbee and Bluetooth, providing multiple connectivity options for climate control and smart-home integration. Aqara’s official documentation confirms W400’s WiFi and Zigbee architecture, while current device listings identify separate FCU and VRF versions. :contentReference[oaicite:4]{index=4}
The S3 primarily uses Zigbee for connected smart functionality and requires a compatible Aqara gateway for app-based features.
It depends on the thermostat model and the features you want to use.
The Aqara S3 relies on a compatible Zigbee gateway for connected Aqara Home functionality.
The W400 includes WiFi connectivity for supported functions, while its Zigbee capabilities can also be used as part of a compatible Aqara ecosystem. Additional Aqara devices or automations may require appropriate hub or gateway support.
Aqara thermostats are particularly attractive for customers who already use Aqara smart-home products.
Depending on the model and ecosystem configuration, climate control can be combined with supported devices such as temperature sensors, presence sensors, switches, lighting and curtains.
This can allow routines such as changing temperature when a room becomes occupied or combining AC settings with a broader home or office automation scene.

Before buying an Aqara thermostat in the UAE, identify the existing AC or HVAC system first.
A thermostat that works correctly with one apartment’s fan coil system may not work with another building that uses a different valve arrangement, voltage or controller technology.
JustCare recommends checking the existing thermostat, wiring and AC details before installation.
Professional installation support is available for compatible Aqara thermostat systems.
A compatibility assessment can identify the existing thermostat voltage, FCU configuration, wiring, fan speeds and valve control before the thermostat is connected.
This is particularly important for wall-powered FCU thermostats because incorrect wiring or choosing the wrong thermostat variant can prevent proper AC operation.
