: An adaptive regulation function balances fluid temperatures in chillers working without an external buffer or water storage tank, preventing short-cycling. Wiring and Connection Architecture
Before diving into the manual, familiarize yourself with the face of the SB655 C:
Prevents end-users from setting the target temperature too low. Compressor On Time (Probe Failure) 0 to 250 min Duty cycle run-time if the main control probe fails. OFt Compressor Off Time (Probe Failure) 0 to 250 min Duty cycle rest-time if the main control probe fails. dty Defrost Type Selection 0 (Electric) 0=Elec; 1=Hot Gas; 2=Timed
To change a value, press , adjust with arrows, and press SET again to store it. Critical Parameters to Monitor: eliwell sb655 c manual
The Eliwell SB655 C is a microprocessor-based digital temperature controller with an onboard relay output. It is part of Eliwell’s “Easy” series, known for its simplicity and robustness. The device is typically panel-mounted and features a bright 3-digit LED display, four buttons for navigation, and a user-friendly interface.
Cause: The cabinet temperature has exceeded SEt + HAL for longer than the tAO time delay.
To clean the front face of the controller, use a soft, damp cloth. Never use abrasive chemicals, solvents, or direct water sprays. Factory Reset (Defaulting the Unit) OFt Compressor Off Time (Probe Failure) 0 to
