Hardware Setup

Hardware setup options for the Teensy Fan Controller (fe. pin mapping, thermistor resistance, etc.).

Input fields on this screen are described when hovered with the mouse cursor.

Temperature Sensors

Up to five (5) temperature sensors are supported, and labeled as supply water temp, return water temp, case temp, aux1 temp, and aux2 temp.

Hardware configuration options for each sensor:

Field	Description
Pin	Teensy (actual) pin number (must support Analog/ADC). Set to 0 if not connected, or to disable the sensor
Thermistor Beta Coefficient	Thermistor Beta coefficient, usually between 3000-4000 (fe. 3950 NTC)
Thermistor Nominal Resistance	Thermistor resistance, usually 10000 (fe. 10k, 50k, etc.)
Thermistor Series Resistance	Ohm value of series resistor used to pull-up thermistor, adjust this to calibrate reading (use a 10k Ohm resistor for 10k thermistor)

Fans

Up to six (6) fans are supported, and labeled by position (fan 1 through fan 6).

Hardware configuration options for each fan:

Field	Description
PWM Pin	Teensy pin number (must support PWM). Set to 0 if not connected, or to not control fan's PWM signal
RPM Pin	Teensy pin number (must support interrupts). Set to 0 if not connected, or to not monitor fan's RPM
