12.1.1. Use of connectors
The controller is provided with spring loaded
terminals suitable for reception of wire with an
end sleeve.
The table below includes permissible size ranges
for wires connected to the controller terminals:
Circuit type Wire cross-section
Power supply circuits 0.75÷1mm
2
*
Low-voltage circuits 0.25÷0.75mm
2
*For installations with bare wire cables the maximal size is
1.5mm 2
For good connection between the terminal
and cable, insulation and sleeve free length
should be in the range of
8÷10mm.
To place wire in terminal press the terminal push
with flat screwdriver, insert the wire end
(with a sleeve on) and then release the push.
Fig. 12.2 Using clamped terminals
12.1.2. Power supply connection
Unit must be installed at disconnected
power supply voltage.
The controller is designed for supply
voltage 230V~, 50Hz. Supply is connected to
terminals marked „

”, „L” and „N”. Electric
connection diagram is presented in Fig. 12.3
230V supply wires must be lead so as
their contact with sensor and other low-voltage
cabling is prevented, additionally, all cables may
not contact surfaces with temperatures that
exceed the cables operating temperature limits.
The controller has no PE protective
connector, because the controller itself does not
require grounding. PE terminals of the pump shall
be connected with PE of supply network,
according to periphery instructions and regulation
concerning electric systems. Proper electric
installation method is responsibility of the
electrician. It is recommended to connect PE
circuits through external screw connector, as
presented in diagrams.
Collector pump must be installed on the
return from the reservoir

12.1.3. Temperature sensor connection
PCSol 150 controller works with temperature
sensors with pt1000 structure, types CT6w and
CT6, with the temperature ranges:
Sensor Type
Temperature range
T1 CT6w
(collector)
-40÷210°C
T2 CT6 (reservoir) -10÷110°C
Sensor CT6 is provided in standard with 2m
long cable, while the collector sensor CT6w with
cable. If you need longer cables, use
0.5÷1.5mm
2
cable not longer than 30 meters,
and connection points must secured against short
circuit and humidity.
CT6w sensor is provided with special
high-temperature silica cables, it must
not be replaced with CT6 sensor, because
of possible insulation damage when the
collector temperature is high.
