The Controlmatic E.2 automatic control unit is used to start and stop the pump (1) in
line with consumer demand. Pressure is indicated by a pressure gauge (2).
Phase No. 1:
When the consumer installation is closed, the pump is stopped. The green "Power"
indicator lamp of Controlmatic E.2 is lit.
Phase No. 2:
When the consumer installation is opened, the water pressure in the system
decreases. The pump is started up.
Phase No. 3:
The pump is running, the yellow "On" indicator lamp is lit.
Phase No. 4:
When the consumer installation has been closed and the flow rate is zero, the pump
is stopped after 10 seconds. The pump is protected from dry running by simultaneous
pressure and flow monitoring. If there is a lack of water, Controlmatic E.2 stops the
pump and the red indicator lamp is lit.
