Many households still rely on aging air conditioners that lack modern smart features—and this creates daily frustrations. Traditional AC units need constant manual adjustments: you might turn it on to cool the room, forget to lower the setting as the temperature drops, and wake up shivering at night. Worse, their temperature control is imprecise; the displayed number rarely matches the actual room temperature, leading to wasted energy and inconsistent comfort.
The biggest issue is accessibility for the elderly. Old AC remotes are cluttered with tiny, unlabeled buttons and confusing modes (like "Auto," "Dry," or "Fan") that are hard to read or understand. For seniors who prefer simplicity, navigating these remotes can be a struggle—if not impossible. This means they either avoid using the AC or endure uncomfortable temperatures, missing out on essential comfort in hot summers or cool winters.
The solution to these frustrations is simple: an electronic thermostat. This compact, affordable device acts as a "smart brain" for your old air conditioner, turning it into a fully automatic temperature controller—no need to replace the entire AC unit. Here’s how it works:
First, the thermostat connects to your existing AC (most models are compatible with minimal wiring). It monitors the room’s actual temperature in real time, adjusting the AC’s output automatically to maintain your desired setting. For example, if you set it to 24°C, the thermostat will turn the AC on when the room warms above that level and off when it cools down—eliminating constant manual tweaks.
And for the elderly? The electronic thermostat is designed for simplicity. It has large, backlit buttons (perfect for low-light conditions) and a straightforward interface: just press "Up" or "Down" to set your preferred temperature, and the device handles the rest. No more squinting at tiny buttons or guessing modes—even non-tech-savvy users can operate it confidently in minutes.

Installing an electronic thermostat from Dongguan Ocean Controls Limited is DIY-friendly—no electrician needed. Follow these steps (note: turn off your AC’s power at the circuit breaker first):
You’ll need a Phillips-head screwdriver, wire strippers (optional, for adjusting wire length), and the thermostat kit (includes device, mounting plate, screws, and manual).
Before starting, confirm the kit has all parts: 1 thermostat device, 1 mounting plate, 2-4 screws, and 1 instruction manual. If any parts are missing, contact Dongguan Ocean Controls Limited via www.riseem.cn.
If your AC has a built-in wall controller or old thermostat, unscrew it from the wall and disconnect the wires. Use a pen to label each wire (e.g., "R" for power, "Y" for cooling)—this prevents confusion later.
Hold the mounting plate against the wall (near the AC’s wiring) and mark the screw holes with a pencil. Drill small pilot holes (for drywall/wood) and secure the plate with the included screws.
Match the labeled wires to the corresponding terminals on the mounting plate (refer to the thermostat manual for a terminal guide). Twist wire ends around terminal screws and tighten firmly—ensure no bare wires are exposed (to avoid short circuits).
Line up the thermostat with the mounting plate (most snap into place; some use small screws). Turn the AC’s power back on—the thermostat will auto-calibrate to the room temperature. You’re now ready to set your desired temperature!
