Models, protocols and software versions may be counted separately. Pricing and production lead time depend on the confirmed configuration and quantity.
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.
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.
Selection and installation reference
The illustrated standard package contains an AcmeLink DK controller, two bare-ended P1/P2 wires (red and black), two self-tapping screws and an adhesive pad. The product body is 74 × 37 × 23 mm and its net weight is 50 g.
AcmeLink DK uses the compatible Daikin P1/P2 controller route, not a Mitsubishi Electric CN105 connection. The two P1/P2 conductors are non-polarized; their red and black colors do not establish positive and negative terminals. The compatible original wired controller can remain connected in parallel.
Isolate HVAC power before wiring. Follow the confirmed P1/P2 connection diagram, then restore power, pair the WiFi module and test power, mode, temperature, fan speed and original-controller operation as supported by the indoor unit. Do not use the ME configuration list as a DK specification.
