Thermostat Operation (Gas Model)

There are three thermostats in the gas valve circuit for temperature control, the safety, control inlet
and drum outlet.
When the selector is set on No Heat/Fluff, power is supplied to terminal 16 but terminates, so there
is no gas valve operation.
When the selector is set on Normal Heat/Cotton Regular, power is fed through the gas valve circuit
only so the safety thermostat controls temperature.
When the selector is set on Med Heat/ Permanent Press, power is fed through the gas valve circuit
but also from terminal 8 through the control inlet resistor circuit.
When the selector is set on Low Heat/ Knits Delicates, power is fed through the gas valve circuit,
from terminal 8 through the control inlet resistor circuit, and terminal 6 through the drum outlet
resistor circuit.
