Changes To Settings - Pentair Pool Products Nocchi R4TE Use And Maintenance Manual

The dP-c setting maintains the system's differential pressure constant at the Hset value entered based on
load changes.
Proportional differential pressure dP-v setting.
The dP-v setting varies the delivery value of the head from the Hset value entered to half its Hset/2 value
based on load changes.
Constant curve Frq setting.
The pump is not regulated. The curve can be set within a range varying between the curve of the pump
obtained at minimum CPS outlet frequency to the curve of the pump obtained at maximum CPS outlet
frequency.

4.2.2 CHANGES TO SETTINGS

"tEP" temperature function.
The default function is deactivated. When it is activated in the constant or proportional pressure setting, the
head set point for the pump is reduced based on the temperature of the water. 4 different positive and
negative settings can be entered (see Chpt. 5.3.2).
AUTO ADAP "Aut" learning function.
The function is deactivated by default. When activated using the constant or proportional pressure setting,
the system modulates the pump's performance in order to satisfy system requirements with the lowest
possible energy consumption level. If the system has a work point with a head lower than the set point head
at maximum frequency, the CPS updates the Hset set point with the minimum value measured. It checks
working conditions and re-updates the set point every 12 hours (see Chpt. 5.3.2).
External "InA" analogue setting.
The default function is deactivated. If activated, the Hset value can be changed using a potentiometer (i.e.
2.5K; 10K) or variable power from 0 to 5V external to the system.
