Introduction:

1  collector  array  –  1  storage  tank 1  pump  and  auxiliary  heating  Description:  The  solar  circuit  pump  (R1)  is  switched  on  as  soon  as  the  switch-on  temperature  difference  (Ton)  between  the  collector  array  (T1)  and  the  storage  tank  (T2)  is  reached.  If  the  temperature  difference  between  the  collector  array  (T1)  and  storage  tank  (T2)  drops  below  the  switch-off  temperature  difference  (?Toff),  or  the  temperature  of  storage  tank  (T3)  reaches  the  preset  maximum  storage  temperature,  then  the  solar  circuit  pump  (  R1)  is  switched  off.  Back-up  heating  by  auxiliary  boiler  (detailed  see  paragraph  4.3):  Within  the  preset  time  section  of  back-up  heating,  if  the  temperature  T3  is  below  the  switch-on  temperature,  then  the  circulation  pump  (  H1)  of  back-up  heating  is  triggered,  when  T3  is  heated  to  the  switch-off  temperature,  circulation  pump  H1  of  back-up  heating  is  ceased.
