Frequently Asked Questions - ITC-306T Inkbird
How do I set the target temperature on my ITC-306T?
Press the SET button until the display flashes, then use the UP and DOWN arrows to adjust the desired temperature. Press SET again to confirm and exit.
Can I switch between heating and cooling modes?
Yes. Press and hold the SET button for 5 seconds to enter parameter mode. Navigate to parameter P0 (H/C) and change it to H for heating or C for cooling. Press SET to save.
How do I calibrate the temperature reading?
Enter parameter mode (hold SET for 5s), go to parameter P4 (CAL), and adjust the offset value using the arrow keys. Positive values increase the displayed temperature, negative decrease.
My controller shows '---' on the display. What does it mean?
The '---' display indicates that the sensor is not connected or is faulty. Check the sensor wiring and ensure the probe is properly plugged into the controller.
What is the hysteresis and how do I adjust it?
Hysteresis (parameter P1) defines the temperature range around the set point where the controller stops and starts. For example, if set to 2°C, cooling turns on 1°C above set point and off 1°C below. Adjust in parameter mode.
Can I use the ITC-306T with a 12V DC power supply?
No. The ITC-306T requires 100-240V AC power. Using a 12V DC supply will not power the device properly and may damage it.
How do I clean and maintain the controller?
Disconnect the unit from power before cleaning. Wipe the exterior with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners. Ensure no moisture enters the housing.
What sensor does the ITC-306T use and can I replace it?
It uses a NTC 10kΩ thermistor probe. You can replace it with any compatible 10kΩ NTC sensor. Ensure the probe is securely connected to the controller terminal.
How do I mount the controller in a panel?
Cut a panel opening of 71x29 mm (2.8x1.14 inches). Insert the controller from the front, then secure it using the included mounting bracket from behind. Tighten gently.
Why does my controller display a negative temperature?
A negative reading means the sensor is below zero. The ITC-306T can measure down to -50°C. If the reading is unrealistic (e.g., -40°C in a room), check sensor placement or replace the probe.
