Instruction Manual

Product Overview

The KING K102A is a double pole line voltage thermostat designed for controlling electric heating systems. It features a bimetal sensor for temperature regulation and is suitable for 120V, 208V, 240V, and 277V applications with a 22A capacity. This mechanical thermostat offers a straightforward and reliable solution for maintaining desired room temperatures.

Specifications

Setup and Installation

Installation of the KING K102A thermostat should be performed by a qualified electrician in accordance with all local and national electrical codes. Ensure power to the heating circuit is completely disconnected at the main breaker before beginning any installation work.

The K102A is a double pole thermostat, meaning it interrupts both incoming power lines when switched to the 'OFF' position, providing a complete disconnect for safety during maintenance or extended periods of non-use. It is designed to sit flush against the wall, allowing for ample wiring room within the electrical box.

Wiring Considerations:

• Verify the voltage and amperage requirements of your heating system match the thermostat's specifications (120-277V, 22A).
• Connect the line voltage wires to the appropriate terminals as indicated in the detailed wiring diagram provided with the product packaging.
• Ensure all connections are secure and properly insulated.
• This thermostat does not require a ground wire connection.

Operating Instructions

The KING K102A thermostat features a simple rotary dial for temperature control. To operate:

1. Power On/Off: Rotate the dial clockwise from the 'OFF' position to turn the heating system on. Rotate counter-clockwise to the 'OFF' position to completely shut off power to the heating system.
2. Set Temperature: Turn the dial to your desired temperature setting, indicated in Fahrenheit. The thermostat will automatically activate or deactivate the heating system to maintain the set temperature.
3. Temperature Control: The bimetal sensor provides temperature control within approximately ±3°F of the set point.

For optimal performance, avoid placing the thermostat in direct sunlight, near heat sources, or in areas with drafts, as this can affect temperature readings.

Maintenance

The KING K102A thermostat requires minimal maintenance. To ensure continued accurate operation and longevity:

• Cleaning: Periodically wipe the exterior of the thermostat with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the internal components.
• Dust Accumulation: Keep the thermostat free from dust and debris, especially around the ventilation slots, to prevent interference with the bimetal sensor.
• No User Serviceable Parts: There are no user-serviceable parts inside the thermostat. Do not attempt to open or repair the unit.

Troubleshooting

If you experience issues with your KING K102A thermostat, refer to the following common problems and solutions:

• Thermostat Not Activating Heating System:
  • Ensure the thermostat dial is turned past the 'OFF' position to a desired temperature setting.
  • Check the circuit breaker for the heating system to ensure it has not tripped.
  • Verify that the thermostat is correctly wired according to the installation instructions.
• Inaccurate Temperature Readings / Room Too Hot or Cold:
  • The bimetal sensor can be affected by internal current flow, potentially leading to readings that are 5 to 7 degrees off. This is a characteristic of mechanical bimetal thermostats.
  • Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources (e.g., lamps, appliances) that could influence its internal temperature sensor.
  • Allow sufficient time for the thermostat to stabilize and react to changes in room temperature.
• Thermostat Feels Warm to the Touch:
  • It is normal for line voltage thermostats to feel slightly warm due to the current passing through them. This does not indicate a malfunction unless accompanied by other issues like burning smells or excessive heat.

If problems persist after attempting these troubleshooting steps, contact a qualified electrician or KING customer support.
