Series 59 displays temperature and other parameters on large, easy-to-read LEDs and provides accurate, stable control. Temperature is sensed by a thermistor, RTD, thermocouple or solid-state relay, and it can be used to turn a heater or refrigeration unit on or off as programmed. Differential and setpoint offset values are adjustable, permitting application-specific programming for stable control and less frequent cycling. Settings can be tamperproof, factory preset or field adjustable.
