Frequently Asked Questions(FAQs)

• Is the STC-3008 compatible with standard K-type thermocouples?
  No, the STC-3008 is specifically designed to work only with the included waterproof NTC 10K thermistor probes.
• Can I use the STC-3008 to control both a heater and a cooler simultaneously? Yes, it features dual independent displays and two separate relay outputs, allowing you to manage heating and cooling processes at the same time.
• Does the STC-3008 work with 110V AC or 12V DC systems?
  No, this specific model requires a 220V AC power supply to operate the main controller unit.
• Can I extend the length of the included NTC probes?
  Yes, you can carefully splice and extend the sensor wires, though extending them beyond a few meters may slightly alter the resistance and affect temperature accuracy.
• What voltage does the STC-3008 require to operate?
  The controller itself must be powered by a standard 220V AC mains supply.
• How much current can the internal relays handle?
  Each of the two internal relays is rated to safely switch loads up to 10A at 220V AC.
• Can the relays output 220V directly to my heater or cooler?
  No, the relays act as dry contacts (switches) and do not output voltage; you must route your own power supply through the relay terminals to your load.
• How do I wire a heating element to the STC-3008?
  You must wire the live AC line into the relay's common terminal and connect your heating element to the normally open terminal, completing the circuit back to neutral.
• Which terminals do I use to connect the NTC probes?
  The NTC probes connect to the dedicated sensor input terminals (typically terminals 3-4 and 5-6) clearly marked on the wiring diagram sticker on the device.
• Do I need an external contactor to use the STC-3008?
  If your connected heater, compressor, or motor draws more than 10A of current, you must use an external AC contactor to prevent melting the internal relays.
• Which Arduino library should I use for the STC-3008?
  The STC-3008 is a standalone industrial controller and does not require an Arduino, microcontroller, or any external libraries to operate.
• Is there a MicroPython library for the STC-3008?
  No, this device operates completely independently and does not run MicroPython or accept custom code.
• Where can I find example code to set the temperature limits?
  You do not need code; all programming, including setting target temperatures and hysteresis, is done directly via the front panel buttons using the P0-P3 internal menu.
