Sophisticated pulse proportional thermostat,
ideal for controlling higher power ceramic heaters.
The function of this thermostat is far more
sophisticated than the simpler on/off switching
devices. It will very accurately control heaters
and has a maximum load of 600 watts. A normal
thermostat switches a heater on full power until
the set temperature is achieved. It then switches
the heater off completely until the temperature
drops below the set value, when the cycle starts
over again. The gap between the heater being
switched on and then off is called hysteresis.
It is between these points that the accuracy
of the controller is assessed. The pulse
proportional thermostat pulses electricity to
the heater.
