►Repress “SET” button, activate and deactivate this function, if deactivate the function,
“EMON - - -” displays on screen.
►Press “ESC” button to exit menu or wait for 20 seconds to exit, set parameters are saved
automatically.
When lighted, and blinks on the screen, it indicates this function is in activated,
and at this moment temperature of tanks reaches to its maximum limited temperature
When only blinks on the screen, it indicates collector temperature is over EMOF
temperature,this function is activated,
but temperature of tank doesn’t reach to its maximum
limited temperature
7.6.2 Submenu - CMX Maximum limited collector temperature( collector cooling function)
Function description:
The collector cooling function delays the vaporization of the heat transfer fluid. Shortly before
reaching the maximum temperature of the collector, the solar pump starts working in order to
cool down the heat transfer fluid using the heat losses occurring in pipelines and storage
cylinder.
When tank temperature rises to its preset maximal temperature, solar circuit pump is ceased
compulsively even the temperature difference is satisfied. If the sunshine is very good, as a
result collector temperature will rise continuously, when collector temperature rises up to its
maximal temperature, solar pump will be triggered again even at the case that tank
temperature is already to its maximal temperature. And solar pump works until the
temperature of collector drops since this reversed circulation or when tank temperature rises
to its emergency temperature 95
o
C ( namely tank emergency stop temperature).
When displays, and blinks on the screen, it indicates that tank emergency
temperature reaches, tank temperature is ≥95
℃
Setup steps:
To access main menu TEMP, then select submenu CMX ,
“CMX 110oC” displays on screen
►Press “SET” button, parameter “110
℃
” blinks.
