Watlow High Limit Control

Replacement Only - Watlow High Limit Control

This FM approved limit control is operated using a separate thermocouple. Mechanical relays (not included) break power to the elements when tripped. A High Limit Control gives added assurance at a small cost that the furnace and materials fired do not exceed the temperature indicated.

NOTE: This item is the replacement controller for an existing furnace. It should not be used in place of another controller, or in a furnace that did not originally use this same controller. Controller only - does not include relays thermocouple, wiring, etc.
