PWM input signal (S - solar)
PWM input signal (S - solar)
At low PWM signal percentages (duty cycles), a hysteres is prevents the circulating pump
form startingand stopping if the input signal fluctuates around the shifting point.Without
PWM signal percentages, thecirculating pump will stop for safety reasons. If a signal missing,
for example due to a cable breakage, thecirculating pump will stop avoid overheating of
the solar thermal system.
