* This special cable with an active built-in NTC protection
circuit, reduces possible inrush currents. To be used in case of
for instance poor quality of relay components that are
sensitive to inrush current.

13.1 Product introduction
Fig. 45 ALPHA SOLAR pump
13.2 Application
The new ALPHA SOLAR pump is designed to be integrated in all
kinds of solar systems with either matched-flow or constant-flow
rate.
13.3 Product description
High-efficiency ECM pumps, such as ALPHA SOLAR, must not
be speed-controlled by means of an external speed controller
which varies or pulses the supply voltage. You can control the
speed with a low-voltage PWM signal from a solar controller to
optimise the solar harvesting and temperature of the system. As a
result, the power consumption of the pump is reduced
considerably.
If no PWM signal is available, you can set the pump to constant
speed, only switched on and off by the controller.
13.4 Operating the product
13.5 Setting by means of the control panel
The user interface is designed with a single push button, one
red/green LED and four yellow LEDs.
.
Fig. 46 User interface with one push button and five LEDs
The user interface shows the following:
• operating status
• alarm status
• settings view, after pressing the button.
13.6 Operating status
During operation, the display shows the actual operating status or
the alarm status.
13.7 Alarm status
If the circulator has detected one or more alarms, the red/green
LED switches from green to red. When an alarm is active, the
LEDs indicate the alarm type as defined in the table below. If
multiple alarms are active at the same time, the LEDs only show
the error with the highest priority. The priority is defined by the
sequence of the table.
When there is no active alarm anymore, the user interface
switches back to operating status.
