+# Temperature-triggered cooling fans (one may define any number of
+# sections with a "temperature_fan" prefix). A "temperature fan" is
+# a fan that will be enabled whenever its associated sensor is above
+# a set temperature. In the event of an MCU software error the
+# temperature_fan will be set to its max_power.

+# sensor_pin parameters.

+#   The maximum range of valid temperatures (in Celsius) that the
+#   sensor must remain within. This controls a safety feature
+#   implemented in the micro-controller code - should the measured
+#   temperature ever fall outside this range then the micro-controller
+#   will go into a shutdown state. Set this range just wide enough so
+#   that reasonable temperatures do not result in an error. These
+#   parameters must be provided.
+#temp: 40.0
+#   A temperature (in Celsius) that the sensor must exceed before the
+#   fan is enabled. The default is 40 Celsius.
+#fan_speed: 1.0
+#   The fan speed (expressed as a value from 0.0 to 1.0) that the fan
+#   will be set to when the sensor temperature exceeds the set value.
+#   The default is 1.0.
