As soon as the pump is connected to the supply, lights up the screen, indicating the current
power consumption.
Defects appear on the screen as "E1", "E2" or "E3" errors.
When the pump goes to the "phase of tilt" when the night-time temperature reduction is acti ated, the on-
screen display is - C.
Selection of pump curves
Whene er the key is pressed, the pump changes.
Press se en times all settings will be executed once.

Fall of ni ht-time temperatura key
By pressing the key automatically the night temperature gets lower. Pressing again the button 5
seconds acti ates the night-time temperature reduction instantly, appearing - C on the display. By pressing key
again, turns the night-time temperature reduction.

Re ulation of the constant pressure curve
During operation, by pressing the pressure cur e requiring the installation (according to the losses of load
and the necessary flow) is chosen.
The pressure cur e is indicated in the diagrams with PD1, PD2, PD3 and PD4.

Curves of constant speed
In the cur es I, II, and III the pump operates at constant speed and flow rate aries according to the load loss of
the circuit along the selected cur e.
Form of the ni ht temperature decrease performance
To acti ate the night temperature decrease press the key If turns on the adjacent field, the decrease of
temperature is enabled and the pump automatically changes from normal operation to the night-time
temperature reduction.
The change depends on the temperature of impulsion. The pump automatically switches to night-time
temperature reduction, when the temperature drops in the next hour more than 10 ° - 15 ° C. The display
shows "-C".
The change to normal operation is carried out without delay, as soon as the temperature rises 3 ° C.
Permanent ni ht-time temperature reduction
The night-time temperature reduction could be adjusted permanently. After acti ating the decrease of
temperature, you ha e to press the button again for 5 seconds. After releasing the button in the display
appears "-C".
The pump is stable in operation decrease until:
- do not press the key again
- does not increase the temperature of impulsion.
In these cases turns on the night temperature decreases, as well as after a power failure.
