3. Setup
- Unpack: Carefully remove all components from the packaging.
- Connect Probe: Insert the temperature probe into the designated port on the main control unit.
- Position Probe: Place the temperature probe in the environment where temperature needs to be monitored and controlled. Ensure it is not directly exposed to heating or cooling elements to get an accurate reading.
- Plug In: Connect the power outlet unit to a standard UK electrical socket. The main control unit will power on and display the current temperature.
- Connect Appliance: Plug your heating or cooling appliance (e.g., heater, fan, incubator) into the power outlet unit of the controller.
4. Operating Instructions
4.1 Basic Temperature Control
The controller operates in two main modes: Heating and Cooling. The mode is determined by the relationship between the Start Temperature (ON) and Stop Temperature (OFF).
- Heating Mode: When Start Temp < Stop Temp. The appliance will turn ON when the measured temperature drops below the Start Temp and turn OFF when it reaches the Stop Temp.
- Cooling Mode: When Start Temp > Stop Temp. The appliance will turn ON when the measured temperature rises above the Start Temp and turn OFF when it drops to the Stop Temp.

4.2 Setting Temperatures
- Press the SET button once. The Start Temperature (ON) will flash.
- Use the UP/CLK and DOWN buttons to adjust the desired Start Temperature.
- Press the SET button again. The Stop Temperature (OFF) will flash.
- Use the UP/CLK and DOWN buttons to adjust the desired Stop Temperature.
- Press the SET button a third time to confirm and exit the setting mode, or wait a few seconds for it to auto-save.
4.3 Timing Modes
The controller offers four timing modes for advanced control. Press the MODE button repeatedly to cycle through these options (F01, F02, F03, F04).

Image: Display examples of the four timing modes (F01 Cycle Timer, F02 CD ON, F03 CD OFF, F04 CD ON, CD OFF) on the controller's LCD screen.
- F01: Cycle Timer (ON/OFF Cycle): Set an ON duration and an OFF duration for the appliance to cycle repeatedly.
- F02: Countdown ON: Set a countdown time after which the appliance will turn ON and stay ON.
- F03: Countdown OFF: Set a countdown time after which the appliance will turn OFF and stay OFF.
- F04: Countdown ON, Countdown OFF: Set a countdown for the appliance to turn ON, and then another countdown for it to turn OFF.
To set the times for each mode, select the desired mode using the MODE button, then press SET and use UP/CLK and DOWN to adjust the hours and minutes.
4.4 Temperature Calibration
If the measured temperature deviates from a known accurate thermometer, you can calibrate the controller:
- With the device powered on, press and hold the SET button for approximately 3 seconds to enter the advanced settings menu.
- Use UP/CLK or DOWN to navigate to the temperature calibration setting (refer to the on-screen indicator or specific symbol in the full manual).
- Press SET to select, then use UP/CLK or DOWN to adjust the calibration value. A positive value increases the displayed temperature, a negative value decreases it.
- Press SET to confirm and exit, or wait for auto-save.
4.5 Backlight Settings
The backlight duration can be adjusted for energy saving or continuous visibility. Access this setting through the advanced settings menu (press and hold SET for 3 seconds) and adjust the backlight timer as needed.
5. Maintenance
- Cleaning: Wipe the controller and probe with a soft, dry cloth. Do not use abrasive cleaners or immerse the units in water.
- Probe Care: Ensure the temperature probe is clean and free from debris for accurate readings. Avoid bending or damaging the probe cable.
- Storage: When not in use, store the controller in a dry, cool place away from direct sunlight and extreme temperatures.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | No power to the outlet; faulty unit | Check the power socket; ensure the unit is properly plugged in. If issues persist, contact support. |
| Inaccurate temperature reading | Probe dirty or damaged; calibration needed; probe placed incorrectly | Clean the probe; perform temperature calibration (Section 4.4); reposition the probe away from direct heat/cold sources. |
| Appliance not turning ON/OFF as expected | Incorrect Start/Stop temperature settings; wrong mode (heating/cooling); appliance not plugged in or faulty | Verify Start and Stop temperature settings (Section 4.2); ensure the appliance is functional and correctly plugged into the controller's outlet. |
| Timing function not working | Incorrect timing mode selected or parameters set incorrectly | Review and adjust timing mode settings (Section 4.3). |
