Smart Thermostat Adapters & Conversion Kits
Connect your existing AC, mini-split, or VRF systems to modern smart thermostats like Google Nest and Ecobee. We supply and install specialized conversion kits across Dubai.
AC to Smart Home Interfaces
24-Volt Conversion Kit
Adds a dedicated C-Wire to older HVAC units, providing continuous 24VAC power required for Wi-Fi thermostats.
- Transformer: 40VA capacity
- Primary Input: 120V / 208V / 240V AC
- Secondary Output: 24V AC
DropAir Adapter
Translates digital communication signals into standard 24V analog logic for ductless mini-splits and VRF systems.
- Protocol: Digital to 24VAC Analog
- Compatibility: Daikin, Mitsubishi, LG, O General
- Efficiency: Retains OEM inverter ramp-up profiles
Umbrella Interface Module
Premium integration hardware designed for complex variable-speed compressors, utilizing digital bus connections.
- Comms Bus: RS-485 / Modbus integration
- Bypass: Overrides proprietary lockouts
- Fault Detection: Passes error codes to displays
DC Multi-Stage kit
Safely isolates high line-voltage from the sensitive low-voltage circuitry of Nest and Ecobee thermostats.
- Relay Type: SPDT / DPDT dry contacts
- Rating: 10A / 250VAC
- Isolation: Opto-isolated triggers

Frequently Asked Questions
Everything you need to know about converting your AC to smart home technology.
Can I install a Nest Thermostat on an O General AC in Dubai?
Yes. Most O General units in the UAE run on proprietary digital logic or lack a 24V C-Wire. By using our DropAir adapter or a 24V conversion kit, we can bypass the standard O General wall controller and allow a Google Nest or Ecobee to command the compressor without losing cooling efficiency.
Will using an adapter void my AC warranty?
Our adapters are non-destructive and interface directly with the factory-provided terminal blocks on your AC's control board. Because we do not cut OEM wiring harnesses, the installation is fully reversible and generally does not void manufacturer warranties.
Why is a C-Wire (Common Wire) so important?
Older analog thermostats ran on internal AA batteries. Smart thermostats have bright LCD screens and active Wi-Fi chips that quickly drain batteries. The C-Wire delivers a continuous flow of 24VAC power from the AC control board directly to the smart thermostat to keep it permanently powered.
