Variable Speed Application Example - Pentair ControlPro Series Installation Manual

Variable Speed application example

ControlPro will enable you to get the most out of a variable speed pump. The system will enable you to use a slow
and energy efficient setting for most of the time and only ramp up the speed when required.
Check your pump manual for selecting pump speeds.

Pump Settings
Speed 1 (step 1 on the pump): low speed filtration.
Set duration to 0 and speed at:
Speed 2 (step 2 on the pump): heating speed
Move the pump speed up to a level where your heater will work. Select one speed higher.
Set duration on the pump to 0. Speed 2 is selected whenever the heater is activated.
Speed 3 (step 3 on the pump): solar speed
Move the pump speed up to a level where your solar system is working OK. Select one speed higher.
Set duration on the pump to 0. Speed 3 is selected whenever the solar is activated. This speed can also be used for
programming a higher filtration speed in one of the timer schedules.
Speed 4 (override on the pump): backwash speed
Select 2850 rpm for a 600mm filter and 3450rpm for a 750mm sand filter in order to generate sufficient flow
when backwashing.
ControlPro settings
Set program 1 at speed 1 from 08:00 to 00:00
This is the 'normal' filtration at low speed for 16 hrs/day.
Set program 2 at speed 3 from 12:00 to 13:00
Set program 3 at speed 3 from 17:00 to 18:00
This is a 'high' filtration speed for 2 hrs a day to provide for even distribution of heat and chemicals in the pool. It will
also help to evacuate heat from under a pool cover when the pool is covered for longer periods.
If you use an automatic pool cover it would be possible as well to link speed 2 or 3 to work whenever the pool cover is
open (see 'setting' menu).
Energy saving example
Applying this programming for a 50m3 pool, 2.4 kWh of electricity is used on 1 day for filtration with the VS pump.
Using a conventional 0.55 kW pump for 10 hrs. a day, 8,5 kWh will be the daily power consumption.
This results is a 6.1 kWh per day (72%) energy saving when using a VS pum !
