The temperature sensors should be connected to the
following terminals with no dependence on polarity:
1 / 2 = sensor 1 (collector outlet)
3 / 4 = sensor 2 (tank bottom)
5 / 6 = sensor 3 (tank top – optional, not included)
7 / 8 = sensor 4 (return flow temperature – optional, not
included)
The power supply is connected to the following terminals:
19 = Neutral - N
20 = Line power - L
12 = Ground
The control is equipped with two relays, one for the
integrated pump in the solar pump station and one for use
in specialty custom applications requiring a second pump:
• Relay 1 (primary pump)
18 = Line power - R1
17 = Neutral - N
13 = Ground
• Relay 2 (secondary pump – optional, not included)
16 = Line power - R2
15 = Neutral - N
14 = Ground

backward through the indication menu or to decrease the
adjustment values.
For system settings adjustment press the forward key to
reach the last display channel. Then hold the forward
button down for 2 seconds and the system setting screens
can then be shown. If an adjustable value is shown on the
display is indicated. To change the set value press the
Set button (3) so that flashes. Adjust the value using
button 1 or 2 until the desired value is shown then press
button 3 so that permanently appears. The adjusted
value is now saved.
