4.4 Main menu - TEMP Temperature
For every system, the factory set parameters are in the best condition that is fully integrated
into the entire solar system. But these parameters can also be set individually to cater the
special requirements, please carefully observe the operation data of system components
after setting.
Note:
parameters that can be set depend on the selected system, not all the parameters
can be adjusted in a solar system.
Following submenus and parameters can be set under TEMP main menu.

4.4.1 EMOF maximum switch-off temperature of collector (Collector Emergency Shut
Down Function)
Function description:
When collector temperature rises up to the maximum switch-off temperature of collector
(EMOF), this function is activated, solar circulation pump is stopped in order to avoid the
damage of system other components caused by high temperature. The adjustable range of
this EMOF temperature is
(
ON+3
℃)~
200
℃
, factory set is 130
℃
. When the temperature
of collector rises up to EMOF temperature, solar circuit pump is locked, but when collector
temperature drops to the maximum switch-on temperature of collector (EMON)( factory set
is 120
o
C), solar circuit pump is unlocked, and this function is deactivated.
