OWNER/INSTALLATION MANUAL

3.9 POOL PUMP OVERRIDE

TERMINALS P1/P2
For installations where e pool filter pump runs
continuously, ese terminals do not need to be used.
For installations where a timeclock controls e pool
filter pump, and e same pump provides water flow
to e heat pump, e heat pump can override "pump
off" periods to ensure e pool is heated/cooled. To
activate is setting please speak to your installer.
When installed in parallel wi
filter pump will run when:
a) a period of "pump on" has been set on e time
clock for filtration purposes.
b) a period of "pump off" has been set in e time
clock and e heat pump runs e pool filter pump for
temperature sampling and if e pool subsequently
requires heating/cooling.

This feature operates by over-riding e timeclock
whenever e controller measures a water temperature
at needs heating/cooling. If e pool does not need
heating/cooling e filter pump will be turned off until
e controller next measures a water temperature
at needs heating/cooling. If e pool needs heating/
cooling e heat pump will continue to run e filter
pump and heat/cool e pool.
This feature will reduce e pool filter pump run time to
minimise pump energy usage.
