4.3.4 CMN low temperature protection of collector 

Description:   

When the temperature of collector is below preset CMN temperatures, solar circuit pump is 

locked,  even  when  the  temperature  difference  between  collector  and  tank  exceeds  the 

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 unlocked for 

operating, controller exits this program.
