SECTION III: SOLAR CONTROL SYSTEM
1.2 Electrical wiring
The power supply of the controller must only be
made by an external power supply switch (last step
of installation!) and the line voltage must be
210 ... 250 Volt (50 ... 60 Hz). Flexible lines are to
be fixed at the housing by enclosed strain relief sup-
ports and screws.
The controller is equipped with 2 standard relays, to
which the
consumers
e.g. pumps, valves etc. can be
connected:
• Relay 1
18 = conductor R1
17 = conductor R1
13 = ground clamp
• Relay 2
16 = conductor R2
15 = neutral conductor N
14 = ground clamp
The
temperature sensors
(S1 up to S4) have to be
connected to the following terminals independently
from the polarity:
1/2 = Sensor 1 (e.g. Sensor collector 1)
3/4 = Sensor 2 (e.g. Sensor store 1)
5/6 = Sensor 3 (e.g. Sensor collector 2)
7/8 = Sensor 4 (e.g. Sensor store 2)
The
power supply
is effected to the clamps:
19 = neutral conductor N
20 = conductor L
12 = ground clamp
Please note:
The relays are semi-conductor-relays for pump speed
control – they need a minimum load of 20 W (power
consumption of the consumer) for faultless function.
If auxiliary relays, motor valves, etc. are connected,
the condenser which is enclosed in the mounting
material, must be connected parallely to the relevant
relay output.
Attention:
for connection of auxiliary relays or
valves, the minimum pump speed must be adjusted
to 100%.
Dangerous voltage on contact!
Electrostatic discharge can lead to damages of
electronic components!
