10.16 Heater Circuit
The water temperature in the heater tank (instant/freshbrew machines)/pressure
boiler (B2C machines) is controlled by a thermistor probe. The thermistor has a
variable resistance; when cold it has a high resistance and when hot it has a low
resistance.
1.
The thermistor probe sits directly in the water and continuously senses
the water temperature. The resistance of the thermistor is interpreted by
the controller as a temperature reading.
N.B. The resistance of the thermistor when at ambient (room)
temperature should read about 3000 ohms, when hot (96°C) it should
read approximately 220 ohms.
