FAQ's of Selec CH403B-2-NTC Cooling Controller:


Q: How do I install the Selec CH403B-2-NTC Cooling Controller?

A: Install the controller by cutting a panel hole measuring 28 x 70 mm, securing the unit in place using mounting hardware, and wiring the NTC sensor and SPDT relay according to the user manual. Ensure all connections use copper conductors suitable for the rated voltage (230V AC).

Q: What types of applications are suitable for this cooling controller?

A: This controller is ideal for use in refrigeration units, commercial freezers, chillers, and cooling cabinets, providing reliable temperature management in both commercial and industrial settings.

Q: Where should the NTC thermistor sensor be placed for accurate temperature measurement?

A: Install the NTC thermistor sensor (10k Ohm at 25C) in the critical temperature zone inside the cooling chamber or area requiring precise monitoring. Ensure it is away from direct airflow or heat sources for optimal accuracy.

Q: What is the process for setting the desired temperature on the controller?

A: Adjust the temperature set point using the keypad located on the front panel. Refer to the controller's user manual for detailed instructions on accessing and modifying the set point settings through the 3-digit LED display interface.

Q: How does the ON/OFF control mode benefit cooling systems?

A: The ON/OFF control mode enables the controller to efficiently manage compressor operation by activating or deactivating the cooling relay based on temperature deviations from the set point. This reduces energy consumption and maintains consistent cooling performance.

Q: What are the main benefits of using this controller in a refrigeration system?

A: Benefits include precise temperature regulation with 1C accuracy, clear status indication via LEDs and buzzer, easy panel mounting, and compatibility with standard NTC thermistor sensors-all ensuring enhanced operational safety and reliability.
