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 its emergency temperature (95
o
C).
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 110
℃
” displays on
screen
►Press “SET” button, parameter “110
℃
” blinks.
►Press “+”“-” button, to adjust the collector protection temperature, adjustable range
(100
℃～
190
℃）
, factory set is 110
℃
►Repress “SET” button, activate and deactivate this function, if deactivate the function,
“CMX - - -” displays on screen.
►Press “ESC” button to exit the menu or wait for 20 seconds to exit automatically,
parameters are saved automatically.
CMX signal displays on screen, it indicates that this function is in activated.
4.5.3 CMN
low temperature protection of collector
Description:
When the temperature of collector is below preset CMN temperatures, solar circuit
pump is ceased, even when the temperature difference between collector and tank
exceeds switch-on temperature difference, solar pump doesn’t work yet. When
temperature of collector is 3
o
C higher that the preset CMN temperature, solar circuit
pump is restarted, controller exits this program.
Setup steps
:
To access main menu TEMP, then select submenu CMN, “CMN-----” displays on screen,
default set is off.
