Pool pump synchronisation
For installations where the filter pump, which also provides water to your HPP, is controlled by a time clock
(supplied by the installer) your HPP can over-ride "pump off" periods set on the time clock so that the filter
pump will run if your swimming pool requires heating. By doing so your filter pump will only run when:
a) A block period of pump "running" has been set on the time clock for filtration purposes.
b) The pool requires heating.
This feature operates by overriding the filter pump time clock for three minutes each hour so that water is
pumped through the HPP
If during this sampling period the heat pump detects a need for water heating it will continue to over-ride
the time clock until the swimming pool temperature is satisfied. If water heating is not required, the filter
pump will turn off after the three minute sampling period and not restart until the next hourly sampling
period or time clock pre-set run time. This feature will reduce the filter pump run time and consequently
save energy as well as unnecessary filter pump wear and tear.
