6.1 T summer 
When this menu is chosen, it is possible to  change 
this value between 11 and 30 °C. The entered value 
is  confirmed  by  pressing 

.  As  soon  as  the  air 

temperature  before  the  heat  exchanger  is  higher 
than  this  value,  the  Aquacom  will  start  up.  When 
the measured outside temperature gets lower, the 
Aquacom will turn itself off until a switching point 
is  reached  again.  Summer  operation  is  not 
dependent on the date. 

 

6.2 T2 Aquacom 
When this menu is chosen, it is possible to change 
this value between 11 and 22 °C. The entered value 
is  confirmed  by  pressing 

.  As  soon  as  the  air 

temperature  after  the  heat  exchanger  during 
summer  operation  is  lower  than  this  value,  the 
Aquacom  will  turn  itself  off.  This  way  the  unit 
makes  sure  the  air  is  not  cooled  back  too  far, 
possibly  causing  draft  complaints.  If  the 
temperature is set  too high, the unit will often be 
turned  off.  It  is  recommended  to  maintain  the 
factory  setting  of  18  °C.  This  parameter  will  be 
ignored  when  the  switching  point  for  winter 
operation is reached. 
 
6.3 T winter 
When this menu is chosen, it is possible to change 
this  value  between  10  and  -10  °C.  The  entered 
value  is  confirmed  by  pressing 

.  As  soon  as 

the  air  temperature  before  the  heat  exchanger  is 
lower  than  this  value,  the  Aquacom  will  start  up. 
When  the  temperature  becomes  higher,  the 
Aquacom  will  switch  off  until  a  switching  point  is 
reached again. Winter operation is not dependent 
on the date. 

 

6.4 Frost limit 
When this menu is chosen, it is possible to change 
this value between 0 and -10 °C. The entered value 
is  confirmed  by  pressing 

.  As  soon  as  the  air 

temperature  after  the  heat  exchanger  is  lower 
than  this  value,  the  pump  will  start  working 
continuously.  When  the  measured  temperature 
becomes  higher,  the  Aquacom  will  turn  itself  off 
until  a  switching  point  is  reached  again.  This 
protection  will  prevent  the  heat  exchanger  from 
freezing by continuously pumping the glycol water 
mixture  in  case  of  severe  frost,  provided  that  the 
unit is not turned off. When this temperature is set 
higher  than  the  switching  point  for  winter 
operation, the switching point for winter operation 
does  not  have  any  effect  anymore  on  the 
operation  of  the  Aquacom.  If  the  temperature 
after  the  heat  exchanger  will  not  rise  by  0.5  °C  in 
10  minutes,  the  unit  will  display  the  error  ' 
Tempdiff  <  0.5K'.  This  error  message  has  to  be 

removed manually by pressing one of the buttons. 
Also see section 5.2.4. 
 
6.5 P summer 
This  submenu  enables  you  to  set  the  reaction 
speed  of  the  pump  during  summer  operation, 
using the P-factor. When this menu is selected, it is 
possible  to  change  this  value  between  8  and  15 
using the 

 and 

 buttons. The entered value 

is confirmed by pressing 

. For a high value the 

Aquacom will respond less quickly. For a low value 
the  Aquacom  will  respond  very  fast.  It  is 
recommended not to change this value. 
 
6.6 P winter 
This  submenu  enables  you  to  set  the  reaction 
speed of the pump during winter operation, using 
the  P-factor.  When  this  menu  is  selected,  it  is 
possible  to  change  this  value  between  8  and  15 
using the 

 and 

 buttons. The entered value 

is confirmed by pressing 

. For a high value the 

Aquacom will respond less quickly. For a low value 
the  Aquacom  will  respond  very  fast.  It  is 
recommended not to change this value. 
 
6.7 Set language 
This submenu enables you to change the language 
of the control unit. After this menu is activated, the 
language can be changed by pressing the 

 and 

 buttons. 

 will confirm you choice. 

 
6.8 Calibrate sensors 
In  this  menu  the  sensors  can  be  calibrated  with 
each  other. 

Only  perform  this  action  when  a 

sensor is replaced and the sensors are at the same 
temperature

. Before you perform this action, place 

both  sensors  together,  preferably  in  a  container 
with  melting  ice-water.  Next  you  select  this  menu 
from  the  main  menu  and  press 

  twice.  The 

control unit now middles the measured values and 
saves these. If you erroneously  entered this menu 
and the control unit shows 'Calibrate sensors', you 
can go back to the main menu by pressing 

. 

 
6.9 Operating hours 
When  this  menu  is  entered,  you  can  switch 
between  displaying  the  operating  hours  during 
summer and winter operation by pressing the 

 

and 

  buttons.  This  counter  is  not  resettable, 

and  if  the  pump  is  replaced,  the  number  of 
operating  hours  needs  to  be  written  down  in  the 
maintenance schedule. 
 
6.10 Error messages 
When this menu is accessed, the display will show 
the  saved  error  messages.  Also  repaired  errors 
which  are  not  deleted  will  be  shown  here.  Using
