POOL PUMP SYNCHRONISING A POOL PUMP WITH A PP22BC CHILLER
For installations where the filter pump, which also provides water to your chiller,
is controlled by a time clock (supplied by the installer) your Calorex chiller can
override “pump off” periods set on the time clock so that the filter pump will
run if your swimming pool requires chilling. 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 chilling.
This feature operates by overriding the filter pump time clock for three minutes
each hour so that water is pumped through the chiller.
If during this sampling period the chiller detects a need for water chilling it will
continue to override the time clock until the swimming pool temperature is
satisfied. If water chilling 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 filter pump run
time and consequently save energy as well as unnecessary filter pump wear
and tear.
A pair of volt free terminals (numbered 15 and 16) are available to allow for the
chiller to be switched on or off remotely.
