Details about Function Parameters
119
The sleeping function requires sleeping mode settings.
If water consumption is small and only
one pump is in variable frequency operation, the system will switch to the sleeping mode and the
main pump will shut down when the working frequency is lower than the sleeping frequency
((F8-20) and the operation time exceeds the sleeping latency time (F8-21). If the small sleeping
pump is used, the small sleeping pump will be started.
①
If the working frequency is the upper
frequency limit or the line frequency and the pressure persists at a value lower than the wakeup
pressure (setting: +F8-22), the system will be restored to normal water supply when the working
time exceeds the wakeup time delay (F8-23);
②
If the pressure persists at a value above the upper
limit of switching pressure (setting: +F8-14), the small pump will operate as determined by the
PID lower limit options (F8-02) (see Page 72); if there is no small sleeping pump and the water
consumption increases, the system will be restored to normal water supply when the pressure
drops below the wakeup pressure (setting: +F8-22) and persists for a time longer than the wakeup
time delay.
