The Hatco 02.16.039.00 temperature control is a mechanical control component designed to regulate heat by monitoring temperature changes and cycling electrical power to the heating element as needed. It operates through an internal sensing mechanism that opens or closes contacts to maintain the selected temperature range during use. This controlled operation helps prevent overheating while supporting stable and efficient performance. Benefits include reliable temperature regulation, straightforward adjustment, consistent operation without electronic complexity, and durable construction suited for routine commercial environments, making it a practical replacement part for maintaining proper temperature control and overall equipment reliability.
