Setup

1. Unpack: Carefully remove the temperature controller and its probe from the packaging.
2. Connect Probe: Insert the temperature probe into the designated port on the side of the controller.
3. Placement: Position the temperature probe in the area where you wish to monitor and control the temperature. Ensure it is not directly exposed to heat sources or drafts that could skew readings.
4. Plug In: Plug the temperature controller into a standard 120V AC power outlet. The VA display will illuminate.
5. Connect Appliance: Plug your heating or cooling appliance (e.g., heater, fan, refrigerator) into the outlet on the front of the temperature controller.

Operating Instructions

Button Functions:

• SET Button: Used to enter and confirm settings. Press and hold to enter parameter setting mode.
• FUN Button: Used to switch between different functions or modes (e.g., temperature control, timing modes).
• UP Button: Increases values or navigates up through options.
• DOWN Button: Decreases values or navigates down through options.

Setting Temperature Control (Heating/Cooling):

1. Press and hold the SET button for 3 seconds to enter the parameter setting mode.
2. Use UP or DOWN to select the desired parameter (e.g., Start Temperature, Stop Temperature).
3. Press SET to confirm your selection.
4. Use UP or DOWN to adjust the value.
5. Press SET again to save the adjusted value and move to the next parameter, or press FUN to exit.
6. The controller will automatically switch between heating and cooling based on your set start and stop temperatures.

Timing Modes:

The controller supports various timing functions for advanced control.

• Cyclic Timing Mode (F01): Allows setting timed ON or OFF periods.

To access timing modes, press the FUN button repeatedly until the desired mode (F01-F04) is displayed. Then use the SET, UP, and DOWN buttons to configure the timing parameters.

Temperature Calibration:

If you notice a discrepancy between the controller's measured temperature and a known accurate thermometer, you can calibrate the device:

1. Enter the parameter setting mode (press and hold SET).
2. Navigate to the temperature calibration setting (refer to the full manual for specific parameter code, usually indicated by 'CA' or similar).
3. Adjust the offset value using UP or DOWN until the displayed temperature matches your reference thermometer.
4. Save the setting by pressing SET.
