When U2 is located between VCC2 and VCC3, for U2 is smaller than VCC3, comparator C outputs a low level, QC1 is off, pull-in switch JCK of relay ZC is off, QC2 is on, pull-in switch JBK2 of relay B2 and pull-in switch JBK3 of relay B3 are both off, for comparator B, since U2 is greater than VCC2 at this time, comparator B outputs a high level, pull-in switch JBK1 of relay ZB1 is on, pull-in switch JAK2 of relay ZA2 is off, and for comparator a, since pull-in switch JAK2 is off, it is off, so the parallel resistance at this time is RB.
When U2 is greater than VCC3, comparator C outputs high level, QC1 switches on, and the pull-in switch JCK of relay ZC is closed, QC2 opens, and the pull-in switch JBK2 of relay B2 and the pull-in switch JBK3 of relay B3 are all open, and the parallel resistor R3 this moment, so this temperature control circuit can select what kind of resistance is parallelly connected according to specific temperature, because the resistance of parallelly connected resistance is different, can exert an influence to the electric current of resistance wire, and then adjust the temperature, so it has the advantage that realizes temperature control voluntarily.
