The Dropair Pro 6s is a smart thermostat adapter for compatible chilled-water fan coil units (FCUs). It connects supported AC motor and valve systems with Google Nest, Ecobee and other compatible smart thermostats for convenient temperature and fan control.
Want to replace an old fan coil thermostat with Google Nest or Ecobee without replacing your existing air conditioning equipment? The Dropair Pro 6s is designed to make this possible for compatible chilled-water fan coil units (FCUs).
Many apartments, villas, hotels and offices use fan coil systems with conventional wall thermostats that control the fan motor and chilled-water valves. These systems may use 100–240V controls that cannot be connected directly to a conventional 24V smart thermostat.
The Dropair Pro6S adapter provides the electrical control interface needed to connect selected FCU systems with compatible smart thermostats. It supports specified AC fan motors, valve arrangements and thermostat configurations, allowing you to upgrade your room controls while retaining the existing FCU where suitable.
For customers in Dubai, Abu Dhabi and across the UAE, the Pro 6s offers a practical approach to modernizing compatible chilled-water air conditioning controls.
Popular smart thermostats are designed around specific low-voltage HVAC control arrangements. However, many existing fan coil units use different power and valve connections.
The Dropair Pro 6s bridges this compatibility gap by connecting a suitable FCU with a supported 24V smart thermostat.
When correctly installed, your connected thermostat can provide supported features such as:
The adapter itself is not a Wi-Fi device. Remote access and smart-home functionality depend on the connected thermostat and its available features.

The Pro 6s is designed for selected fan coil units with AC fan motors and compatible valve controls.
Unlike an adapter intended for a proprietary refrigerant AC communication protocol, the Pro 6s is built to handle defined electrical connections commonly found in chilled-water FCU installations.
Supported arrangements include selected 2-pipe and 4-pipe fan coil systems. The correct configuration depends on the FCU’s motor, valves, existing thermostat and wiring.
This makes the Dropair Pro 6s particularly relevant for properties where chilled-water air conditioning is controlled through a conventional multi-speed fan coil thermostat.
One of the main advantages of the Dropair Pro 6s is its support for several types of fan coil valve control.
Depending on the model-specific configuration, the adapter can work with:
Not every valve configuration is interchangeable. The valve voltage, wiring arrangement and electrical load must be checked before installation.
Many fan coil systems provide three fan-speed settings to adjust airflow according to the room’s cooling requirements.
The Dropair Pro 6s supports compatible AC fan motors with low, medium and high fan-speed connections.
When paired with a suitable smart thermostat, these connections can be configured for supported multi-speed operation.
The manufacturer’s technical specification lists AC motor operation at 100–240V with a rated motor load of 3A.
Fan control must be configured according to the actual FCU motor and thermostat capabilities.
Some chilled-water systems use modulating valves instead of conventional open/close valves.
For these applications, the Dropair Pro 6s supports a 0–10V DC valve control output, specified at 20mA in the manufacturer’s manual.
This allows the adapter to work with selected compatible modulating valve arrangements when the appropriate optional cable and wiring configuration are used.
Before ordering, confirm whether your fan coil unit uses an open/close valve or a 0–10V modulating valve, as the installation requirements differ.
The Dropair Pro 6s includes a built-in 24V AC output designed to supply compatible low-voltage smart thermostats.
The adapter itself uses a 100–240V AC, 50/60Hz power supply.
In suitable installations, the integrated 24V output removes the need for a separate standard thermostat transformer. Additional components may still be required for particular wiring arrangements.
All mains-voltage connections should be completed by a qualified technician.
At just 43 × 43 × 28 mm, the Dropair Pro 6s has a compact white housing designed to fit into suitable electrical installation spaces.
Its small size makes it useful when upgrading an existing fan coil thermostat without carrying out a complete replacement of the FCU control equipment.
Red and green LED indicators help technicians identify power and thermostat-control signal status during installation and testing.
The Dropair Pro 6s is intended for compatible chilled-water fan coil systems using AC motors and supported valve control arrangements.
Compatibility is not universal. The FCU motor type, valve design, electrical load and existing thermostat wiring must be reviewed before choosing the adapter.
Systems using 0–10V DC fan motors may require a different Dropair adapter, such as the Pro6X.
The Pro 6s installation documentation includes connection guidance for the following thermostat families:
Compatibility with newer thermostat generations should be confirmed separately.
For a documented Nest option, explore the Google Nest Learning Thermostat 3rd Generation.
If you prefer Ecobee, view the Ecobee Smart Thermostat Premium. Confirm the exact Ecobee model and FCU configuration before purchasing the adapter.
The Pro 6s is designed to connect directly with supported 24V smart thermostats.
For selected 220V smart thermostats, including compatible Tuya, Orvibo, McoHome and Heatmiser models, the manufacturer’s documentation specifies an additional Dropair iPanel interface.
The iPanel connects between the 220V smart thermostat and the Pro 6s using the specified wiring arrangement.
This additional interface must be included in the system design where required. A 220V thermostat should not be connected directly to a 24V thermostat interface without the correct conversion equipment.

Specifications are based on the supplied Dropair Pro6S installation and service manual. Additional compatibility checks are required for individual FCU systems and valve configurations.
The Pro 6s connects compatible fan coil electrical controls with a supported smart thermostat.
If you would like to understand the preparation and compatibility process, read our guide to smart thermostat installation and AC compatibility.
Although both products help connect compatible air conditioning equipment to modern smart thermostats, they are designed for different control requirements.
The Pro 6s is intended for selected chilled-water fan coil units using compatible AC motors and valve controls.
It is particularly relevant when the existing thermostat controls the FCU fan speed and water valve through conventional electrical connections.
The Dropair Mini 6s is designed for selected refrigerant-based air conditioning systems that use supported manufacturer-specific communication interfaces.
These systems may include compatible inverter, split, multi-split and VRV/VRF indoor units.
The correct adapter depends on the AC control system, not the size of the property. A large villa can have several FCUs that require Pro6S adapters, while a small room may use a refrigerant AC system that needs a Mini6S-based solution.
For conventional thermostat conversion requirements, you can also review the 24V Thermostat Conversion Kit. The correct solution should be selected after checking the existing control system.
Installing a smart thermostat on a chilled-water fan coil system requires more than replacing the wall controller.
The technician must check the existing thermostat wiring, valve operation, fan motor type, voltage and electrical load before selecting the appropriate adapter.
