4. Setup

1. Unpack: Carefully remove the thermostat plug and temperature sensor from its packaging.
2. Connect Sensor: Plug the 3-meter temperature sensor into the designated port on the thermostat unit.
3. Position Sensor: Place the waterproof temperature sensor in the area where temperature needs to be measured and controlled (e.g., incubator, greenhouse, aquarium). Ensure the sensor is not directly exposed to heat sources or extreme drafts that could affect readings.
4. Plug In: Insert the KETOTEK KT3100BL thermostat plug into a standard wall outlet (AC 100-250V).
5. Connect Appliance: Plug your heating or cooling appliance (e.g., heater, fan, pump) into the outlet on the front of the thermostat plug.

5. Operating Instructions

5.1. Temperature Control Range

The KETOTEK KT3100BL supports a wide temperature control range, making it suitable for both heating and cooling applications.

Image 5.1: Temperature Control Range. This image highlights the broad temperature range of -40°C to 120°C (-40°F to 248°F), suitable for various heating and cooling devices.

5.2. Temperature Control Mode

In temperature control mode, the device regulates the connected appliance based on set start and stop temperatures.

Image 5.2: Heating and Cooling Modes. This graphic illustrates how the thermostat operates in heating mode (start temp < stop temp) and cooling mode (start temp > stop temp).

• Heating Mode: The appliance turns ON when the measured temperature is ≤ Start Temperature and turns OFF when the measured temperature is ≥ Stop Temperature. (Requires Start Temperature < Stop Temperature).
• Cooling Mode: The appliance turns ON when the measured temperature is ≥ Start Temperature and turns OFF when the measured temperature is ≤ Stop Temperature. (Requires Start Temperature > Stop Temperature).

5.2.1. Setting Temperature Parameters

1. Press the SET button once. The "Start Temperature" value will flash.
2. Use the UP (▲) or DOWN (▼) buttons to adjust the desired Start Temperature.
3. Press SET again. The "Stop Temperature" value will flash.
4. Use the UP (▲) or DOWN (▼) buttons to adjust the desired Stop Temperature.
5. Press SET a third time to save the settings and exit. If no button is pressed for 10 seconds, the device will automatically save and exit.

5.3. Timer Functions

The KETOTEK KT3100BL offers four distinct timer modes. Press the MODE button to cycle through the timer functions (F01, F02, F03, F04) and temperature control mode.

Image 5.3: Timer Functions F01, F02, F03, F04. This image displays the interface for setting each of the four timer modes, showing the 'ON' and 'OFF' durations.

• F01 Cycle Timer: The appliance works for a set "ON" time and then stops for a set "OFF" time, repeating cyclically.
  Setting: Press SET, adjust "ON" time (hours/minutes) with UP/DOWN, press SET, adjust "OFF" time, press SET to save.
• F02 Countdown ON: The appliance starts working after a set countdown period.
  Setting: Press SET, adjust countdown time (hours/minutes) with UP/DOWN, press SET to save.
• F03 Countdown OFF: The appliance works only for a set duration and then stops.
  Setting: Press SET, adjust working duration (hours/minutes) with UP/DOWN, press SET to save.
• F04 Countdown ON, Countdown OFF: The appliance starts working after a set "CD ON" time, then stops after a set "CD OFF" time.
  Setting: Press SET, adjust "CD ON" time, press SET, adjust "CD OFF" time, press SET to save.

5.4. Temperature Calibration

If the measured temperature deviates from a known accurate reference, you can calibrate the sensor.

1. In temperature control mode, press and hold the SET button for 3 seconds to enter the advanced settings.
2. Use UP (▲) or DOWN (▼) to navigate to the calibration setting (usually indicated by a 'CAL' or similar icon).
3. Press SET. Use UP (▲) or DOWN (▼) to adjust the calibration value (-9.9 to 9.9 °C/°F).
4. Press SET to confirm and exit, or wait for automatic exit.

5.5. Reset Function

To restore the device to factory default settings, locate the reset button (often a small pinhole) and press it with a thin object (e.g., paperclip) for a few seconds. Alternatively, some models may allow a button combination press for reset. Refer to the device's specific instructions if a pinhole is not present.

6. Typical Applications

The KETOTEK KT3100BL thermostat plug is versatile and can be used in various environments requiring precise temperature regulation.
