HD LED Readout Anti-Fog Waterproof Square Display Smart Control Water Heater Temperature Management

Product Overview
This square LED digital temperature display assembly is a dedicated visual temperature reading spare part for tankless gas water heaters. Equipped with anti-scratch metal decorative frame and high-brightness digital tube screen, it matches dual independent high temperature braided wire harness with lock-in plastic plugs. The screen receives resistance signal from NTC water temperature sensor, converts the signal into real-time Fahrenheit hot water temperature value and displays it digitally, allowing users to clearly know outlet water temperature for convenient summer & winter adjustment. Heat resistant braided wire and standard square outline perfectly adapt to the front panel installation layout of most household gas water heaters, ideal aftermarket replacement spare part for damaged, dark screen or loose original display screens.

Is self-installation possible, or is professional installation required?
Answer: You may install it yourself if replacing a compatible OEM component and following basic electrical safety procedures. If you are unfamiliar with electrical work or dealing with non-standard setups, professional installation is highly advised.

Which smart features is this display equipped with at present?
Answer: Local smart control is available on the core unit via the touchscreen. For remote operation, an optional Wi-Fi/Bluetooth add-on module is required. Please ask about our smart connectivity packages.

What is the proper way to clean the touch screen?
Answer: Clean with a soft, slightly damp microfiber cloth. Do not use abrasive detergents, chemicals, or spray liquid directly on the screen, as moisture may penetrate the edges.
