PROPORTIONAL CONTROL (PWM)
The proportional channel (from set point to set point -
for heating, from set point to set point + for
air-conditioning) is divided into four equal zones. At the
end of each cycle time, the thermostat controls the
ambient temperature and, according to the differences
recorded, it modulates the proportion of the ON and OFF
commands transmitted during the cycle time. The
diagrams below show the behaviour of the proportional
control in heating and air-conditioning operations.
