The Hatco 02.16.039.00 Temperature Control is a replacement part component used in compatible commercial systems and heated holding equipment to regulate internal temperatures. It senses the cabinet’s heat level and opens or closes its internal electrical contacts to cycle the heating element on or off, helping maintain the desired set temperature during service. Installed within the equipment’s control panel, this temperature control works with the warmer’s thermostat and heating assembly to deliver consistent warmth throughout the holding area.
