Fig. 5.23 Installation of the VR 10 temperature sensor
• Push one of the VR 10 temperature sensors (1)
supplied with the solar control in the now vacant
immersion sleeve, as illustrated in Fig. 5.23.
• Connect this temperature sensor to terminal "SP 1" in
the auroMATIC 560 solar control.
• Push a further 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.
• Connect the collector temperature sensor to terminal
"Kol 1" in the auroMATIC 560 solar control.
• Establish the connection between the terminal "EP" in
the auroMATIC 560 solar control and the terminal
"Cyl." in the Control Center VR 65.
Manual - Solar hot water systems
• Establish the eBUS connections from the boiler and
VRT 360 to the Control Center VR 65.
The electrical connection of the VR 65 is described in
the VR 65 installation manual (item no. 00 2000 7476),
the connection of the VRT 360 in the operating and
installation manual of the VRT 360 (item no. 838 568).
Fig. 5.24 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.
• Establish the connections to the mains supply.
h Note!
Programme the hot water channel of the VRT
360 or VRC 400 to constant. Programme the
auroMATIC 560 solar control to provide hot
water when required by the customer.
Note!
h
The auroMATIC 560 control will only signal to
the boiler if the cylinder is below target tempe-
rature, if solar system is not operating and if
the programmer is on.
