The SeaAir Touchscreen Display is a phone-format Android device that runs the SeaAir app right on the bulkhead. It wires straight to DC power and straight to your machine's control board, so it is on whenever the breaker is. No battery. No charging. No pairing. The full SeaAir app, on the wall: modes, set point, fan, humidity, power budgets, system health and analytics, plus the help beacon. Wired to DC Power: powered by the boat, with no internal battery to charge or replace. Direct connection to the control board: live from power-on and automatically pairs with the connected machine. Controls every SeaAir unit aboard: reaches the other machines on the boat over Bluetooth or Wi-Fi. Keeps itself current: app and firmware updates install automatically over the air. Sips power: minimal draw, dims and sleeps when idle, wakes on touch. Specs: 5.5" capacitive touchscreen · 4.8" × 2.8" (121 × 68 mm) face · flush bulkhead mount · DC hard-wired · wired communication and also supports Bluetooth and Wi-Fi. Works with every app-enabled SeaAir climate control system. Call us before you cut the bulkhead and we'll confirm the cutout for your install.
