To keep your unit running for a decade, the TGC BC-90-1H manual recommends the following monthly routine:

Based on repair logs from eBay and industrial recyclers, the number one failure in the BC-90-1H is the input fuse (often 10A or 15A, 250V ceramic) followed by cold solder joints on the output relay. Before buying a new unit, open the case (after unplugging!) and visually inspect the main fuse and the large solder pads near the thick red and black output wires.

Since the "manual" is technical in nature, the following specifications are critical for integration:

Because the TGC BC-90-1H manual is sometimes written in dense technical language, users often ask:

Q: Can I charge two 12V batteries at once? A: Yes, if you wire them in parallel (positive to positive, negative to negative). The manual notes that the total amp-hour (Ah) capacity should not exceed 300Ah for optimal charging.

Q: My display shows 0.0 amps. Is the charger broken? A: No. If the battery is already full, the charger is in Float mode. Try connecting a known dead battery. If the amperage stays at 0, check the fuses.

Q: Where can I download a free PDF of the TGC BC-90-1H manual? A: While TGC’s official website hosts most manuals, you can often find the PDF on industrial tool databases or by contacting TGC customer support directly. Avoid third-party sites requiring credit cards for “instant access.” tgc bc-90-1h manual

The TGC BC-90-1H is a specialized bathroom remote control designed for use with TGC (Towngas) instantaneous gas water heaters in Hong Kong. This wired controller allows users to manage water temperature and safety settings directly from the bathroom, ensuring a comfortable and safe bathing experience. Key Controls and Functions

The BC-90-1H interface is designed for simplicity and safety, featuring several key buttons and indicators:

Power (On/Off) Button: Used to activate or shut down the water heater. Start: Set 12/24V → Connect red+black → Plug in

Temperature Adjustment Buttons: Typically marked with arrows, these allow you to set the hot water temperature between 35°C and 60°C.

Priority Button & Indicator: This is crucial when multiple controllers (e.g., kitchen and bathroom) are installed. Pressing "Priority" gives that specific remote control the authority to change the temperature.

High Temperature Indicator: A red light illuminates when the temperature is set to 50°C or higher as a warning to prevent scalding.

Operation Lamp: Displays the status of the heater. It often turns from green (standby) to orange or yellow when the burner is active.

Fault Display: If an error occurs, the temperature screen will show a specific fault code (e.g., "11" for ignition failure) to help with troubleshooting. Operation Guide

Turn On: Press the [On/Off] button. The display should light up, showing the previously saved temperature (often defaulting to 42°C for new installations).

Claim Priority: If the priority light is not on, press the [Priority] button. You cannot change settings unless the priority light on your specific remote is lit. If you need a specific page from the

Adjust Temperature: Use the arrow buttons to reach your desired heat. For safety, the system typically won't allow temperature changes while water is actually flowing at high temperatures.

Start Water: Simply turn on your shower or faucet. The heater will ignite automatically. Safety and Maintenance

Scalding Prevention: Always check the water temperature with your hand before stepping into the shower.

Automatic Reset: If the heater is left in standby for more than 10 minutes, priority is often released, and high temperatures (above 50°C) may reset to a safer 48°C for the next user.

Cleaning: Use a soft, damp cloth to clean the controller. Do not spray water directly onto it or use harsh chemical solvents.

Wired Connection: The BC-90-1H is a wired unit. If the screen is blank, ensure the main power to the water heater is on.
