The Star Mfg Z5958 Griddle Thermostat 100°F–450°F is a temperature control component designed to regulate heat in compatible parts used in commercial electric systems. It operates within a 100°F to 450°F temperature range and uses a sensing bulb connected by a capillary tube to monitor the griddle surface temperature. When the selected temperature is reached, the thermostat cycles the heating elements on and off to maintain consistent heat during cooking.
