Catalogues, samples & wholesale quotations
Standard MOQ: 60 units/sets
Models, protocols and software versions may be counted separately. Pricing and production lead time depend on the confirmed configuration and quantity.
Sample options
After requirements and payment are confirmed: stock samples approximately 3 working days; functional/protocol configuration 15–20 working days; logo, manual or packaging adjustments approximately 10 working days.
Confirm your application before ordering
Send the complete indoor-unit model, communication connector or wiring photos, required protocol and control functions. Compatibility depends on the exact unit and ordered configuration.
These are not one-size-fits-all products. ACMELEC loads or selects the applicable protocol only after confirming the air-conditioner brand, complete indoor-unit model and communication terminals.
Choose by control objective
Choose S20 when the project needs a visible wall thermostat and Tuya smart control. Choose AcmeLink_GW when the project needs RS485 Modbus integration, automation control or a separate compatible wall interface.

FAQ
Compatibility questions
Does one unit work with every VRF brand automatically?
No. The hardware platform is configurable, but the correct brand protocol and wiring must be selected for the actual indoor unit.
Which brands can be considered?
The supplied compatibility references cover many major VRF brands, including Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries, Hitachi, Toshiba, Panasonic, Hisense, Haier, Midea, Gree, York and LG. Exact support remains model-specific.
