5. Overview of components
The
RM Favorit
has a modular design. Each component can be separately changed.
5.1 Components of the pump-controller
The pump-controller (see Chapter 4.1) monitors the pressure and volume flow rate in the pressure line
system. The direction of flow is marked by an arrow on the housing
.
The
green LED (3)
indicates ready to use. The
red LED (2)
indicates an error. That means the pump
controller registers air in the system and when this happens the red LED flashes. If this state continues for
more than 12 seconds, the pump undergoes an EMERGENCY STOP. The red LED then remains
continuously lit.
After an EMERGENCY STOP, the pump is restarted by pressing the
RESET button (1)
(or alternatively, by
disconnecting the plug from the electrical supply).
The pump-on pressure can be set using the
adjustment screw (5)
. This adjustment is required only in
special cases. It is recommended that only experienced professionals use the pressure setting option. The
pump-on pressure is set to 1.5 bar by default. That means the pump switches on when the system
pressure falls below 1.5 bar. (Anti-clockwise rotation decreases the power-on pressure. Clockwise rotation
increases the power-on pressure
.)
The pump-on pressure
can be
controlled whereby the water pressure is
released very slowly. (
The only way to know
the
exact pump-on pressure
is by the pressure indicator,
which will indicate the slowly dropping pressure.)
Note:
The adjustment screw (5) should not exceed the limit of maximum pump pressure! If it is too high for use,
then a separate pressure limiter must be added on the pressure side. In special cases of constant pressure
use, the RM Favorit-SC is suitable. Here you can electronically set the maximum allowable pressure.
