Explanation
SXĂćĂMaximum cylinder temperature
2
to
90ĂºC
Prevents the cylinder from further loading if
the selected value has been exceeded. The
maximum cylinder temperature control is
factory activated by FNĂ=Ă1 (see pageĂ20).
CLĂćĂCollector limit temperature
110
to
200ĂºC
The solar circuit pump is switched OFF
when this temperature has been exceeded
to protect the solar components.
CXĂćĂMaximum collector temperature
100
to
190ĂºC
The solar circuit pump is started (collector
cooling) if this temperature is exceeded
(solar circuit idle, maximum cylinder
temperature has been reached).
The cylinder temperature can go beyond the
maximum cylinder temperature "SX", but
no higher than 90ĂºC (safety shutdown).
CNĂćĂMinimum collector temperature
ć10
to
+90ĂºC
Minimum start-up temperature which must
be exceeded to start the solar circuit pump.
This prevents the pump being started too
frequently.
With CNĂ=Ă10ĂºC, this function is not active.
ć10.0 to +Ă9.9ĂºC for frost protection function
10.1 to 90ĂºC for minimum temperature
