4. Setup

4.1 Initial Connection

1. Unpack the temperature controller and its accessories.
2. Insert the temperature probe into the designated port on the controller. Ensure it is securely connected.
3. Plug the temperature controller into a standard 230V AC 50HZ power outlet. The display will illuminate.
4. Plug your heating or cooling device (e.g., heater, fan, pump) into the controlled outlet on the temperature controller.

4.2 Probe Placement

Place the temperature probe in the environment where you wish to monitor and control the temperature. Ensure the probe is not directly exposed to heat sources or drafts that could skew readings. For liquids, ensure the probe is fully submerged if applicable.

5. Operating Instructions

5.1 General Operation (Both Models)

• Power On/Off: The device powers on automatically when plugged in.
• Display: The LCD screen displays the measured temperature, set parameters, and current mode.
• Celsius/Fahrenheit Switching: For TC819, press and hold the SET button for 3 seconds to switch between °C and °F. For TC816, this function is typically integrated into the settings menu.
• Backlight Control: For TC819, press the DOWN button to turn off the backlight. Press any button to turn it on again.
• Memory Function: All current settings are saved automatically after power off.

5.2 TC816 Specific Modes and Settings

The TC816 offers various timing and temperature control modes:

Figure 5.1: TC816 Timing Functions. This image displays the four main timing modes of the TC816: F01 (Cycle Timer), F02 (Countdown On), F03 (Countdown Off), and F04 (Countdown On and Countdown Off), along with brief descriptions of each.

• F01 Cycle Timer Mode: Sets a repeating ON/OFF cycle. Useful for intermittent operation.
• F02 Countdown On Mode: The device remains OFF for a set countdown period, then turns ON.
• F03 Countdown Off Mode: The device remains ON for a set countdown period, then turns OFF.
• F04 Countdown On and Countdown Off Mode: Combines F02 and F03, allowing for a delayed ON followed by a delayed OFF.

Setting Temperature Range:

1. Press the SET button to enter temperature setting mode.
2. Use the UP and DOWN buttons to adjust the start temperature.
3. Press SET again to move to the stop temperature setting.
4. Use UP and DOWN to adjust the stop temperature.
5. Press SET to confirm and exit.

Temperature Calibration (TC816):

Figure 5.2: TC816 Temperature Calibration. This image illustrates the process of calibrating the temperature on the TC816 by long-pressing the 'Mode' button for 2 seconds to enter real-time temperature calibration.

To correct temperature readings if they deviate from a known standard:

1. Long press the MODE button for 2 seconds to enter real-time temperature calibration.
2. Use the UP and DOWN buttons to adjust the calibration value.
3. Press MODE again to save and exit.

5.3 TC819 Specific Modes and Settings

The TC819 offers 5 distinct modes for temperature and countdown control:

Figure 5.3: TC819 Instructions for Use. This diagram details the functions of the TC819's buttons and features, including how to switch modes, set parameters, adjust temperature correction, switch between Celsius/Fahrenheit, control backlight, and the memory function.

• TC MODE (Temperature Control): Standard temperature control mode, allowing setting of start and stop temperatures for heating or cooling.
• CD TC ON MODE (Countdown to Turn On Temperature Control): The device counts down for a set period, then activates temperature control.
• CD TC OFF MODE (Countdown to Turn Off Temperature Control): Temperature control is active, then deactivates after a set countdown period.
• CD ON MODE (Countdown On): The device turns on after a set countdown period.
• CD OFF MODE (Countdown Off): The device turns off after a set countdown period.

Switching Modes (TC819):

• Press the MODE button (represented by the house icon) to cycle through the 5 available modes.
