PUMP STATION CONTROL INSTRUCTIONS
CONTROL INSTRUCTIONS
Prior to operation of the control on the solar pump station the collector and tank temperature sensors must be prop- erly connected. Remove the control cover and connect the sensors to the proper terminals.
Figure 32
Figure 33
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 
OPERATION AND FUNCTION
Figure 34
The controller is operated by 3 pushbuttons below the display. The forward key (1) is used for scrolling forward through the indication menu or to increase the adjustment values. The backwards key (2) is used for scrolling 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.
