Frequently Asked Questions
Q: What types of refrigeration systems is this controller compatible with?
A: The EK-3030 is designed for middle and low-temperature cold storage systems, compatible with most commercial refrigeration units up to 1HP compressor capacity.
Q: How does the defrost cycle memory function work?
A: The controller remembers the defrost cycle timing even after power interruptions, ensuring consistent defrost operation without manual resetting.
Q: Can I use different sensor types with this controller?
A: The controller is designed for NTC sensors (10KΩ/25°C, B value 3435K). Using other sensor types may require additional calibration.
Q: What's the difference between the three work modes?
A: Refrigeration mode cools, heating mode warms, and constant temperature mode maintains precise temperature within set parameters.
Q: How do I access the advanced parameter settings?
A: Press and hold specific key combinations (detailed in the manual) to enter advanced setting mode. The key lock can prevent accidental changes.
