Daikin Brc1c51 61 Installation Manual Link

Before starting, review these critical safety measures provided in the official Daikin documentation :

While many Daikin remotes are non-polarized (meaning the wires can be swapped without issue), some older systems or specific configurations may require strict adherence to polarity (+/-). Consult the indoor unit's wiring diagram. The manual generally advises against using shielded cable unless necessary, but if electromagnetic interference is a concern, grounding the shield at one end only is standard practice. daikin brc1c51 61 installation manual
