PWM operating mode (Pulse-Width Modulation)
By changing the hysteresis settings (chapter “Configuration settings”), you can turn on
the PWM operating mode. In this mode, AURATON Libra cyclically turns on the heating
device in order to minimize temperature fluctuations. AURATON Libra checks
temperature rise times and temperature drop times.
Knowing these values makes AURATON Libra turn on and off the heating device in
appropriate cycles to maintain the temperature to the set value as close as possible.
1 – Temperature
2 – Time
3 – Set temperature
4 – Room temperature
IMPORTANT:
AURATON Libra can turn on the heating device despite the fact that the
temperature in the room is higher than the set temperature in the PWM mode.
This is caused by the PWM algorithm aiming at maintaining the set
temperature and anticipating the behavior of the thermal system.
