Settings  of  each  controller  option  are 

described below. 

6.1.

 

Setting of deltas 



14 

The 

controller 

allows 

to 

set 

temperature difference 

dT=T1-T2

 that 

will start the collector pump.  

Possible  setting  values  are: 

4,  6, 

8, 10, 12, 14K

.  

6.2.

 

Critical  temperature  alarm 

AL 

Critical  temperature  is  such  collector 
temperature  (T1  sensor)  that  despite 

collector  pump  stopping,  after  reaching  reservoir 
temperature  preset,  will  start  collector  pump  in 
order  to  discharge  excessive  heat  from  the 
collector.  

The  controller  allows  you  to  turn  on  or  off 

loud alarm for the collector critical temperature. If 

AL

  option  is  off,  the  controller  will  not  sound 

audible  alarm  when  the  critical  temperature  is 
reached,  but  it  will  take  alarm  action  (discharge 
heat from the collector into the reservoir). 

6.3.

 

Maximal 

DHW 

temperature 

Max85÷95 

The  controller  allows  you  to  set 
maximal temperature for the reservoir. 
It  is  T2  temperature  above  which  the 

controller  will  start  the  reservoir  overheating 
alarm  and  it  will  stop  heat  loading  to  the 
reservoir. 

This alarm has the highest priority and it will 

always  stop  the  collector  pump  operation.  It 
means  that  even  in  case  of  critical  collector 
temperature, the reservoir overheating alarm will 
disable the collector pump from further operation. 
 

It  possible  to  set  three  values  for  the 

reservoir  maximal  temperature  option:  85,  90, 
95°C

CONTROLLER 

OPERATING 

ALGORITHM 

When 

switched 

on 

the 

controller 

automatically starts to control the collector pump 
operation. 

When  the  T1  sensor  temperature  reaches 

minimal  collector  operation  value  (TCOLmin),  the 
controller  will  enable  the  collector  pump 
operation. Such status is indicated by illumination 
of  the  sun  symbol  indicator.  When  the  collector 
temperature  drops  two  degrees  below  minimal 
temperature  preset,  the  sun  symbol  will  go  off 
and the controller will disable the collector pump, 
if the last was working.  

 

The 

collector 

minimal 

temperature  

TDHWmin is set by selecting edition at the 
sun symbol indicator 

If  the  temperature  difference  between  the 

collector  and  reservoir  (T1-T2)  exceeds  value  set 
in  options  as  d4÷14  and  the  minimal  collector 
temperature  is  reached  (sun  indicator  is  lit),  the 
controller  will  start  the  collector  pump  and  it  will 
be loading heat into the reservoir (sun indicator is 
lit)  until  the  temperature  difference  T1-T2<dT-2 
(current dT is lower than preset by two degrees) 
or  the  collector  temperature  (T1  sensor)  drops 
below  minimal  collector  temperature  (TCOLmin-
2). Then, the collector pump will be turned off.  

The controller turns the collector pump off 

and  on  in  cycles,  depending  on  sunlight intensity 
and  reservoir  conditions,  by  the  time  when  the 
DHW  reservoir  preset  temperature  (TsDHW)  is 
reached.  

 

The  reservoir  preset  temperature  TsDHW  
is  set  by  selecting  edition  at  the  T2 
indicator 

When 

the 

DHW 

reservoir 

preset 

temperature  is  reached,  the  controller  will  stop 
the 

collector 

pump, 

until 

the 

reservoir 

temperature (T2 sensor) is lower than the preset 
by  one  degree  (T2<TsDHW-1).  Then,  the 
controller  will  restart  the  collector  pump,  if 
current conditions allow the reservoir loading. 

When  the  collector  pump  is  stopped, 

because  the  reservoir  preset  temperature  has 
been  reached,  the  controller  will  monitor  the 
collector  temperature  (T1  sensor)  and  if  it 
exceeds  preset  value  TCOLcr,  the  controller  will 
start  the  collector  pump  to  discharge  the 
collector’s critical temperature. When the collector 
temperature drops in relation to TCOLcr preset by 
2°C, the controller will stop to force its operation.  

 

The  collector  critical  temperature  TCOLcr  
is  set  by  selecting  edition  at  the  T1 
indicator
