What is a smart thermostat adapter?
A smart thermostat adapter is a hardware interface that enables modern Wi-Fi thermostats (like Nest, Ecobee, or Honeywell) to control commercial VRV/VRF air conditioning systems. DropAir adapters translate standard 24V thermostat signals into protocols understood by inverter-based HVAC systems.
Which HVAC systems work with DropAir?
DropAir adapters support major brands including Daikin, Mitsubishi Electric, LG, Samsung, Toshiba, Fujitsu, and Panasonic. Our adapters work with VRV/VRF systems, multi-split systems, and inverter air conditioners using RS-485, 0-10V, or IR control protocols.
Do I need external power for installation?
No. DropAir Mini 6 and Pro 6X include integrated 24V transformers, eliminating the need for external power supplies. This simplifies installation and reduces equipment costs for contractors and integrators.
What is the minimum order quantity for B2B customers?
MOQ varies by product and region. For distributors and OEMs, we offer flexible ordering starting from 50 units. Custom white-label solutions are available for volume orders. Contact our sales team for specific pricing and terms.
Does DropAir provide technical support?
Yes. All B2B partners receive comprehensive technical documentation, installation guides, and direct engineering support. We offer 8 years of firmware updates and regional partner training programs.
Can DropAir adapters be white-labeled?
Absolutely. We provide OEM customization including custom branding, packaging, and firmware configurations for qualified partners. This enables HVAC manufacturers and distributors to offer smart thermostat compatibility under their own brand.
