12.18 Solar Operation (Optional)
12.18.1 Solar Operation:
Solar function:
-
This function allow user to control the solar pump to operate depend on the solar sensor reading compare to
the tank installed. Solar pump will circulate the hot water energy store at solar panel to heat up the DHW
Tank or Buffer Tank.
Solar Connection Diagram:
a) Solar function can only enable when the Optional PCB is connected.
b) Few part as below need to install to control the solar operation:
-
Solar
Panel
-
Solar
Pump
-
Solar Panel Sensor
-
Tank Sensor (Buffer tank sensor
OR
DHW Tank sensor depend on the connection direction)
* During Solar Connection to the system, installer need to alert on the high water temperature may flow to the
zone circuit or DHW piping circuit. Therefore pipe which withstand higher water temperature need to be
installed.
