Heating System
The heating system consists of:
Water Tank
Heating Elements
High-limit Thermostat
Temperature Sensor
DV Switch
The heating circuit maintains the water in the tank at a preset temperature this ensures that the water is always ready
for brewing.
Water for brewing is contained in a 3 gallon stainless steel tank. This tank contains a 1680W @ 120VAC heating
element that is powered by the line voltage into the machine. The heating element is controlled by the control board
through a mechanical relay. The dual voltage ITCB-DV HV brewer adds an additional 2268W for 208/240VAC ap-
plication; the two elements are wired in series when selected for 208/240VAC.
The control board monitors the water in the tank by a temperature sensor that is in contact with the water. This
temperature sensor is a digital thermistor; the control board reads the temperature as value of resistance. The tem-
perature sensor allows the control board to trigger the heating element triac when the temperature drops below its
programmed value and shut down the trigger voltage when the water temperature reaches the programmed holding
value.
