The overall block diagram of the series of RLC Circuit (s-domain) is shown in the following figure. In fact when forward biased, the forward voltage drop accross a diode has a temperature dependance, in particular has a negative linear(ish) slope. This is a 230VAC Temperature Fan Control circuit. If the temperature should increase high enough, the switch will open and break connection to the high pressure pump motor relay and time delay relay. The interior fan is powered through two separate fuses and a blower motor relay. (104 engines) Schematic Besides, a popular BiMos Op-amp CA3140 (IC2) is used to sense the status of the temperature sensor IC1, which also controls a solid-state switch formed by a high power Triac BT136 (T1). THe transduced is a diode in the forward polarization regime.
