5 Installation
Wiring plan 5
- Boiler from third party manufacturer
- Wiring via standard wiring box
- Solar circuit control via VRS 560
- Solar cylinder reheating control via a separate hot
water programmer from a third party manufacturer
- Heating circuit control via a separate central heating
programmer from a third party manufacturer
- Overview of the connection of the cylinder thermostat
to the wiring box.
- Installation of two VR 10 temperature sensors in the
solar cylinder (see Fig. 5.35)
- Attachment of the solar gain sensor to the solar
circuit return (see Fig. 5.35)
- Connection of the solar pump to the solar control via
its own thermal cut out (see Fig. 5.36)
• Fit a wiring box near to the cylinder for easy electrical
connection.

Fig. 5.35 Installation of the VR 10 temperature sensor
• Push one of the VR 10 temperature sensors (1)
supplied with the solar control in an immersion sleeve
where there is still room, as illustrated in Fig. 5.36.
• Connect this temperature sensor to terminal "SP 1" in
the auroMATIC 560 solar control.
• Push a VR 10 temperature sensor (3) in the immersion
sleeve for the bottom cylinder area.
• Connect this temperature sensor to terminal "SP 2" in
the auroMATIC 560 solar control.

• Attach the temperature sensor for the gain (2) to the
return pipe of the solar circuit nearby the solar
cylinder.
• Connect this temperature sensor to the terminal
"Ertrag" in the auroMATIC 560 solar control.
• Make sure the temperature sensors of the immersion
heater, solar cylinder and solar control fit properly in
the immersion sleeves.
h Note!
Set the controller of the cylinder thermostat to
target temperature (1, Fig. 5.20).
• Set the maximum temperature (MAXT 1) of the
auroMATIC 560 solar control to 70 ºC
(see auroMATIC 560 manual).
• Connect the collector temperature sensor to terminal
"Kol 1" in the auroMATIC 560 solar control.
Fig. 5.36 Connection diagram of the solar pump TCO
• Connect the solar pump, the thermal cut out intended
for this purpose and terminal "Kol 1-P" of the solar
control to each other by means of an additionally
protected terminal strip.
• Wire up the boiler of the third-party manufacturer, the
programmer and the room thermostat.
• Establish the connections to the mains supply.
