1. TO CHOSE THE TYPE OF CONTROL
Choose the type of control required between constant differential pressure "dPc", proportional
pressure RdPv" or constant frequency "Frq".
2. TO SET THE SET POINT
- SET POINT 1: head or frequency required by the system. The module varies the motor speed to
maintain the system pressure as near as possible to that set. During the regulation of this
parameter, the writing "dPc 1, dPv 1 o Frq 1" appears.
- SET POINT 2: Present only if the module was set to function with two set points (SETn = 2", see
"ADVANCED PARAMETERS"). When setting this parameter the display shows "dPc 2, dPv 2 o
Frq 2".
If two SET POINTS are present, it is possible to select the one desired using the "S.P." external contact (see
chapter 3.5) or the internal clock (see Chapter 5.3).
3. tEP TEMPERATURE FUNCTION
The default function is deactivated (tEP=5).
Set tEP<>5 to activate the function and install the optional NTC
temperature sensor. In this case, the set point for the head of the
pump will be reduced or increased based on the temperature of the
water.
If (5<tEP<=9), delivery head for the pump will increase to between
the minimum set value and the set point value.
If (5<tEP<=9), delivery head for the pump will decrease to between
the set point value and the minimum set value.

4. AUTO ADAP (auto-learning) FUNCTION Aut
The default function is deactivated (OFF).
To activate the function, set the value to ON. If the work point head is less than Hset and the pump is
at maximum speed, the control assumes this value as a set point. After running for approximately 12
hours, the control system will change the status of the hydraulic system increasing the set point by
0.2 m, if necessary.
