For installations where the filter pump, which also priovides water to your
heat pump, is controlled by a time clock (supplied by the installer) your
Calorex heat pump can overridde "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 heat pump.
If during this sampling period the heat pump detects a need for water
heating it will continue to override 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 untl the next
hourly sampling period or time clock pre set run time. This feature will
reduce filter pump run time and consequently save energy as well as
unnecessary filter pump wear and tear.
