2.2 Key Features

• Wide Temperature Control Range: Regulates and maintains temperatures from -40°F to 248°F (-40°C to 120°C).
• IP65 Waterproof Rating: The integrated waterproof shell allows for outdoor use, protecting against rain. For optimal waterproofing, hanging the unit is recommended.
• Illuminated LED Display: Provides clear temperature readings and settings, even in low-light conditions.
• High and Low Temperature Alarms: Alerts users if the temperature exceeds or falls below a set range, protecting connected devices or environments.
• Switchable Units: Easily switch between Fahrenheit (°F) and Celsius (°C).
• Temperature Calibration: Allows for fine-tuning of temperature readings for accuracy.
• Compressor Delay Protection: Customizable delay settings protect refrigeration equipment from frequent on/off cycles.

4. Operating Instructions

The DTC310 features an intuitive interface with a SET button, an Up button, and a Down button for configuration.

4.1 Display Overview

The LED display shows three main values:

• PV (Process Value): Current temperature detected by the probe.
• RV (Run Value): The temperature at which the connected device will activate (e.g., heater turns on, cooler turns off).
• SV (Stop Value): The temperature at which the connected device will deactivate (e.g., heater turns off, cooler turns on).

Indicators for 'Run' and 'Stop' will illuminate to show the status of the connected device.

4.2 Setting Temperature Parameters

Follow these steps to configure the temperature settings:

1. Switching °F or °C: Press the Up and Down buttons simultaneously to toggle between Fahrenheit and Celsius.
2. Enter Preset Mode: Long press and hold the SET button for 3 seconds to enter the temperature preset mode.
3. Set Run Temperature (RV): Use the Up or Down buttons to adjust the desired Run Temperature.
4. Set Stop Temperature (SV): Short press the SET button to move to the Stop Temperature setting. Use the Up or Down buttons to adjust the desired Stop Temperature.
5. Save Settings: Long press and hold the SET button for 3 seconds to save your settings and exit the preset mode.

4.3 Advanced Settings (P0-P8 Parameters)

The DTC310 may include advanced parameters for fine-tuning operation, such as compressor delay, temperature calibration, and alarm thresholds. Refer to the detailed parameter list below for specific functions and adjustment methods. To access these settings, typically a longer press of the SET button or a combination of buttons is required.

To access advanced parameters: Long press the SET button and the Up button simultaneously for 3 seconds. Use Up/Down to navigate parameters (P0-P8). Press SET to enter a parameter, adjust with Up/Down, then press SET again to confirm. Long press SET to exit.
