Installation guide
Electronic superheat controller
Type EIM 316 / 336
Introduction
Superheat controller EIM series is for use where superheat must be accurately
controlled, typically in commercial air conditioning, commercial and industrial heat pumps,
commercial refrigeration and food retailing applications.
Reference: For details please see EIM data sheet.
