FAQs:
Q1. What is the sensor input type used in CC-522?
A1. The CC-522 uses an NTC sensor with a temperature measurement range from –50.0°C to +99.9°C.
Q2. Can the controller operate in both heating and cooling modes?
A2. Yes, the controller can be configured for heating, cooling, or both based on your application's requirements.
Q3. What happens if the sensor fails or is disconnected?
A3. The display will show an error (OPN), and the compressor relay behavior can be configured to turn ON, OFF, or operate in a duty cycle for safety.
