THREE EASY STEPS

STEP 3 - (continued)

Comparison between ON/OFF and propor

tional contr

Due to it’s high diff

erential, ON/OFF control mode w

astes a lot of energy. The graphic below shows

how the ON/OFF method creates high "o

ershoot" abov

e the temperature set point while the

electronic proportional method keeps the temperature close to the set point. The shaded areas

correspond to wasted energy

A proportional control can thus maintain an accurate room or discharge

temperature without the typical v

iations of the ON/OFF method. This represents an energy sa

ving

of approximately 15%.
