The company’s new electronic appliance temperature control, ETC1H, reportedly eliminates the need for defrost controllers, fan and light controls, and has integral compressor protection to provide accurate temperature control. The ETC1H cold control can have up to three temperature sensors, an optional remote display with controls, and output for direct control of compressors up to 16 A without an intervening relay. The control features two auxiliary outputs for heaters, fans, and lights in any combination. The optional remote display provides temperature information, high temperature tracking, alarm indication, and pushbutton setting. An alarm buzzer is also optional.
Other features include compressor protection from over- and under-voltage conditions and a built-in timer that is said to ensure pressure equalization on startup. Built-in routines include diagnostics and self-checking for the appliance.
