Digital controller applied for cooling and/or heating, they feature an internal audible alarm (buzzer), configurable digital filter and accept 3 types of sensors: NTC thermistor (-50 to 105°C / -58 to 221°F), PT100* and PT1000* (-200ºC to 300°C / -328 to 572°F). It has 5 configurable outputs: refrigeration, heating, minimum ventilation, alarm and timer. When used for climate control in CPD rooms, for example, it rotates up to 4 air conditioners at a time and provides a backup based on temperature in case of failure of one or more devices. Its fifth relay can be used as an alarm and/or power outage alert. In addition, it features a clock, hourmeter and datalogger which allows storage of the temperature value at specified periods of time, the variation of temperature and the status of the outputs. It also features a built-in rechargeable battery, which allows the data recorded to be kept even after a power fault.

It monitors HACCP critical points (Hazard Analysis and Critical Control Point) by means of records in the controller's memory of high temperature alarm, power failure, and digital input. Complies with FDA guidelines - CFR 21, part 11.
