2 Electrical connection

The regulator must be supplied with electricity at a voltage of 210 ... 250 V (50...60 Hz) via an external switch (final step!). The cables must be clamped in the
unit's cable clamps by tightening the screws provided.
1 Sensor terminals
2 Terminal block earth
3 T6.3 A fuse

The regulator is fitted with 3 relays to which the following components are
connected:
• Relay 1 (primary circuit pump, speed control)
R1 = Cable R1
N = Neutral N
PE = Earth terminal
• Relay 2 (secondary circuit pump, speed control)
R2 = Cable R2
N = Neutral N
PE = Earth terminal
• Relay 3 (tank zone changeover valve)
R3 = Cable R3
N = Neutral N
PE = Earth terminal
The temperature sensors (S1 to S3) are connected to the following
terminals (SX and GND):
S1= Collector temperature sensor
S2 = Tank temperature sensor
S3 = Heat exchanger temperature sensor
Connection to the mains is made via the following terminals:
Earth terminal
Neutral N (terminal block)
Cable L
