Setup Instructions
1. Mounting the Controller
The controller features two keyholes on its back for convenient wall mounting. Choose a suitable location away from direct heat or moisture.

This image displays the rear of the thermostat controller, clearly showing the two keyholes designed for easy and secure wall mounting.
2. Connecting Devices
The controller has two independent outlets: one for heating and one for cooling.
- Plug your heating device (e.g., heat mat, ceramic heater) into the outlet labeled "HEATING".
- Plug your cooling device (e.g., fan, chiller) into the outlet labeled "COOLING".

This image highlights the front panel of the controller, detailing the "HEATING" and "COOLING" outlets, the "SET" button, and the "UP" and "DOWN" arrow buttons for temperature adjustment.
3. Placing the Temperature Probe
Insert the waterproof temperature probe into the environment you wish to control. Ensure the probe is securely placed and will accurately measure the temperature of the target area. Avoid placing the probe directly on a heat source.
Operating Instructions
1. Power On/Off
Plug the controller into a standard electrical outlet. The display will illuminate, showing the current temperature.
2. Setting the Desired Temperature
- Press the SET button once. The display will flash, showing the current set temperature.
- Use the UP or DOWN arrow buttons to adjust the desired temperature.
- Press SET again to confirm your selection, or wait a few seconds for the setting to save automatically.
3. Switching Temperature Units (°F/°C)
To switch between Fahrenheit (°F) and Celsius (°C), press and hold the SET button for approximately 3 seconds until the unit changes on the display.

Advanced Settings
The controller offers several advanced functions for precise environmental control. Refer to the detailed instructions below for specific programming steps.
Compressor Delay
This feature prevents rapid cycling of cooling devices, extending their lifespan.
High & Low Temperature Alarm
Set upper and lower temperature limits. An alarm will sound if the temperature goes outside this range.
Temperature Calibration
Adjust the temperature reading to match an external, accurate thermometer if necessary.

Maintenance
- Regularly wipe the controller unit with a dry cloth. Do not use abrasive cleaners or immerse in water.
- Inspect the temperature probe and cables for any signs of damage. Replace if necessary.
- Ensure the probe tip is clean and free from debris for accurate readings.
Troubleshooting
Display Not Working
- Check if the power cord is securely plugged into a working electrical outlet.
- Verify the power outlet is functional by plugging in another device.
Incorrect Temperature Reading
- Ensure the temperature probe is correctly positioned and not directly touching a heating or cooling element.
- Check the probe cable for damage.
- Perform a temperature calibration if you suspect consistent inaccuracies.
Heating/Cooling Device Not Activating
- Confirm the device is properly plugged into the correct outlet (HEATING or COOLING).
- Check the set temperature and ensure it is outside the current temperature range to trigger activation.
- Verify the device itself is functional by plugging it directly into a power outlet.
