Installation in the Solar Circulation Unit
●
Affix the SUNGO S with the appropriate screws to the
wall mounting bracket of the solar circulation unit.
●
Open up the cable ducts next to the centre crosspiece in
the bottom of the control.
●
Remove outer insulation of the cables in such way that
single isolated wires start as they enter the casing from
the bottom.
●
Hold the connectors with one hand while tightening the
screws in order to minimise pressure on the circuit board
and to avoid tearing the connectors off.
●
Last connection should be to mains.
●
If power is switched on now, 230V AC will be present on
the casing of the triacs.
3.2 Connecting Wires
Layout of the SUNGO S connections
All connections are made to the circuit board at the bottom
of the control. On the right hand side you will find the con-
nections for the sensors (low voltage area) while on the left
hand side you will find the connections for mains and
switching output A1.
General connection rules
●
If flexible wires are used and the controller is fitted to the
wall, wires must be tied externally in such way that strain
to the controller is avoided.
●
In this case you must tin or crimp the wire ends.
●
If required PG9 screws can be fixed at the feed-throughs
if the control is mounted to the wall.
230 V mains connection
●
Mains power is connected from outside the connector
via an ON/OFF switch.
If the unit is connected with a plug to a socket, the switch
can be omitted.
●
The unit is designed to work with 230V AC/50Hz. Please
check that your pump has compatible specifications.
●
All earth wires are connected to the PE-connectors.
●
The neutral terminals (N) are connected electrically.
●
Switch output A1 is a 230 V normally open contact which
is activated via speed-control.
Connecting the temperature sensors
●
The wires for the temperature sensors can be extended:
Up to 15 m length = 2 x 0.5 mm² cable can be used; up to
50 m = 2 x 0.75 mm² cable is necessary.
For long connections it is recommended to use shielded
cable.
Do not connect the shielding at the sensor end, just trim
and isolate!
●
Temperature sensors are without polarity and can be
connected any way.
●
Sensor wires must be installed away from mains carrying
cables.
Lightning protector module
The SUNGO S is fitted with spike protection on all sensor
terminals. Generally, further protection of the cylinder sen-
sors is not required.
Sensor T1 (collector) requires installation of sensor con-
nection box SP2 with excess voltage protection.
