N321R NTC defrost Temperature controller, 1 relay The N321R is a specialized temperature controller designed for refrigeration systems, featuring an efficient compressor-off defrost cycle that enhances system performance and prevents ice buildup. It supports Pt100 and NTC sensors for precise temperature monitoring across a wide range. A key benefit is its programmable defrost functionality, allowing users to set automatic intervals and durations while maintaining accurate temperature display during defrost cycles. The controller includes configurable minimum ON/OFF times to protect compressors from short cycling, adjustable hysteresis for fine-tuned control, and a manual defrost button for immediate operation. With its robust IP65 front panel and multiple power options (including 24V DC and RS485 communication models), the N321R ensures reliable operation in demanding environments while optimizing energy efficiency and extending equipment lifespan.
