Wiring the Solar Control Panel
Terminal Clamps in the lower part of the controller (terminal cover removed)
1
Power connection terminal block
L: 1x phase conductor (mains input)
R1, R2: 2x output (TRIAC, for pumps or valves)
X: not used
Lconst.: 2x phase conductor (outputs, permanent voltage)
N: 4x neutral conductor (common neutral conductors for mains power input and outputs)
Note: Outputs R1 and R2 are protected by an electronic fuse.
2
Protective conductor terminal block:
PE 4x protective earth (common protective earth for power connection) terminal block
3
Signals terminal block:
1 – 4: 4 x sensor input (Pt1000 temperature sensor)
5: 1 x sensor input (Pt1000 temperature sensor or pulse water meter input)
RS: 1 x signal output (potential-free relay contact for safety extra-low voltage)
PWM R1, R2: 2 x control output (for PWM-controlled high-efficiency pumps)
7 x mass connection (common mass for sensor inputs and control outputs)
4
