An exclusive design with a shield next to the funnel handle that deflects hot liquids away from the user’s hand.

Static pressure is the measurement of water that is not moving or flowing.

Switches are devices designed to allow current/voltage to pass or not to pass, depending on whether it is "open" or "closed". There are many different configurations available to satisfy many different applications. They are as simple as a single pole, single throw (wall switch), to the much more sophisticated "gauge" type switches that have multiple layers and can switch many components off or on at the same time. They come in many different packages as well. Membrane switches are common in touch pads, float switches are reed switches that are activated by magnets, and mechanical switches are sets of contacts.

Thermal cut off, or sometimes referred to as TCO, is a fuse that acts in the same way as a limit thermostat. If the temperature reaches a certain level the TCO fuse will blow just the same as any other fuse, cutting power to the tank heater. The TCO is also current sensitive.

A thermistor is a temperature sensitive resistor used to monitor temperatures. It changes value as it cools or heats. NTC (Negative Temperature Coefficient) thermistors will decrease in ohms value as it heats, and are commonly used in temperature sensing. PTC (Positive Temperature Coefficient) thermistors increase in ohms value and are generally used in protective circuits by monitoring over current conditions.

A thermoelectric cooler (TEC) is a small cooling device that relies on a Peltier junction. Composed of two conductors made of different materials, a Peltier junction acts as a heat pump which can cool or warm when current is passed through it. For example as current passes through one side is hot and the other is cold. This device is used to chill, (approximately 20º from ambient air temperature), but not refrigerate concentrate product.

BUNN offers a full line of vacuum-insulated servers and brewers that brew directly into these servers that keep coffee at optimal flavor for hours and save on energy consumption and by not requiring warming plates.

The timer board is designed to provide the voltage to a specific device in order to energize it. It can energize a relay, inlet solenoid, pump, dump valve or other device for brewing or can energize a motor to grind coffee, to name a few.

The board consists of an inferred LED and a photo transistor which monitor the auger shaft and motor pin distance. The microprocessor will determine the shut off point of the refrigerant solenoid in relation to the thickness (distance) setting in the function menu.

Total dissolved solids, or TDS, is the total weight of the solids that are dissolved in the water, given in ppm per unit volume of water.
