Series 58

Series 58 Analog Electronic Controls
Low cost reliable water temperature thermostat

□ Precise temperature control to ±1.5°F
□ Safe thermistor sensor allows direct immersion
□ Interchangeable components, no matched parts

□ Remote sensor and set point knob
□ Second pot available for two location adjustment
□ Fail safe operation, de-energizes on sensor open/short
□ UL listed

Series 58 is designed for reliable control of water temperature and finds application in pools, spas and hot tubs. In addition, a two- zone control feature is offered, which is particularly suitable for boilers and for hot tubs. Through an SPDT relay, series 58 will control a gas valve or electronic ignition and activates when the sensor temperature drops 1 degree F below set point. The standard series 58 includes a controller, sensor and set point potentiometer. For two-zone control, a second potentiometer is supplied, which operates from the single sensor. A precise thermistor assembly is supplied as standard (22 AWG lead wire with PTFE insulation and 3/8in diameter x 0.9in length probe) - safe for direct immersion. All components are fully interchangeable (no matched components).
