Curves of constant speed
In the curves I, II, and III the pump operates at constant speed and flow rate varies according to the load loss of
the circuit along the selected curve.
Form of the night temperature decrease performance
To activate 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 night-time temperature reduction
The night-time temperature reduction could be adjusted permanently. After activating the decrease of
temperature, you have 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.
