6. Setup and Wiring

Before wiring, ensure the power supply is disconnected. Incorrect wiring can damage the device or connected equipment. If you are unsure, consult a qualified electrician.

Wiring Connections:

1. Power Input: Connect the DC 12V power supply to the designated input terminals on the back of the controller. Observe polarity (+/-) carefully.
2. Load Output: Connect the device you wish to control (e.g., heating element, cooling fan) to the output terminals. The controller acts as a switch for this load. Ensure the load's power requirements do not exceed the controller's maximum output (120W for the 12V model).
3. Temperature Sensor: Insert the temperature sensor probe into the environment where temperature measurement is required. Ensure it is securely placed and not directly exposed to heat sources or drafts that could skew readings.

Warning: Always disconnect power before making or changing any wiring connections.

7. Operating Instructions

Setting the Target Temperature (SV):

1. Press the SET button once. The SV (Set Value) display will begin to flash.
2. Use the Up and Down arrow buttons to adjust the target temperature to your desired value.
3. Press the SET button again to confirm the setting and exit the setting mode.

Cooling/Heating Mode Selection:

The controller can operate in either cooling or heating mode. This is typically configured via an advanced parameter (often labeled P0 or P1). Please consult the full product manual for specific instructions on how to access and set the cooling or heating mode.

Advanced Parameter Settings (P3, P4, P5):

To access advanced parameters, typically a long press of the SET button is required. Use the Up/Down buttons to navigate between parameters (e.g., P0, P1, P2, P3, P4, P5) and then press SET again to enter the parameter's value adjustment mode.

• P3 Setting (Delay Stop/Compressor Protection): If P3 is set to '1', the thermostat will stop running for 1 minute. This function is often used for compressor delay protection in cooling systems. A long press of the SET button is required to trigger this function again after it has completed its cycle.
• P4 Setting (Delayed Start): If P4 is set to '1', the thermostat will begin operation after a 1-minute delay. During this delay, the digital display will not illuminate until normal operation commences. A long press of the SET button is required to trigger this function again.
• P5 Setting (Parameter Lock): By default, P5 is set to 'OFF'. Once the desired temperature and other parameters are configured, setting P5 to 'ON' will lock the data, preventing accidental changes. To modify settings again, P5 must be set back to 'OFF'.

Temperature Calibration:

The device supports temperature calibration to fine-tune accuracy. This is usually an advanced parameter (e.g., P7 or P8). Refer to the full product manual for specific instructions on how to access and adjust the temperature calibration offset.

High/Low Limit Temperature Setting:

The controller allows setting upper and lower temperature limits to prevent extreme conditions. These are typically accessible through advanced parameters. Consult the full product manual for details on setting these limits.

8. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Sensor Care: Ensure the temperature sensor is clean and free from debris for accurate readings.
• Connection Check: Periodically check all wiring connections to ensure they are secure.
• Storage: If storing the device for an extended period, disconnect it from power and store it in a dry, cool place.
