AT1-5

Cooling point controller plus cooling / OEM

The AT1-5 series comprises low-cost refrigeration controllers with heating or cooling function and a high-performance relay up to max. 16A (heating) and 8A (inductive compressor switching capacity). Its strengths lie in the simple parameterization, self-explanatory membrane keypad, an INFO menu with the most important information and door contact switch. The function of the second output can be freely selected and thus triggered, for example, by the I/O button or, in the case of light control, via the M button.

  • Universal controller for flush mounting
  • Integrated defrosting functions
  • Approval for R290 (version …EH-G)
  • Direct compressor control via high-power relay up to 16(8)A
  • Selectable NTC10K or PTC input
  • Configurable auxiliary output for four operating modes
  • Alarm messages due to temperature and door opening
  • Optional light control button
  • Connection to monitoring systems such as LAE TAB
  • UL-certified
