This feature gives unusual speed of response to rapid changes of water temperature thereby preventing thermal lag. It has open on rise contact action. This control may be used as a high limit or as a low limit control. These controls have special contacts which are suitable for use on low voltage and millivolt (thermocouple generator type) circuits as well as line voltage gas valve and motor loads. DESCRIPTION THESE CONTROLS MUST BE INSTALLED BY A QUALIFIED INSTALLER. Do not exceed the specifica
