Uwaga! Podanie napięcia na zaciski 1-12 powoduje uszkodzenie regulatora – Note! Connecting power
supply to terminals 1-12 will damage the controller
Temperature sensors
Temperature sensors should be connected to the following (polarity not important):
1,2 T1 – solar panel sensor (type T1301)
3,9 T2 – bottom sensor of primary tank (type T1001)
4,10 T3 – top sensor of primary tank (type T1001)
5,11 T4 – additional sensor, in a system with precise heat measurement, sensor of
return from the coil pipe (type T1001)
Sensor cables must be routed separately from the power supply cables.
Flow meter
8,12 Flow meter, input for connecting the flow meter pulser.
