When the program runs, the lamp will turn on and heat the NTC device until the resistance drops below
the value you have stored in the Analog Branch element (under the Start element). When the resistance
drops below the value you have stored, the lamp will turn off and the fan motor will turn on to cool the
NTC device until the resistance rises above the stored value in the lower Analog Branch element. When
the resistance rises above the stored value, the fan motor will turn off and the lamp will turn back on,
repeating the cycle.
