 User permission level

The user interface can be programmed to make certain buttons

and functions unavailable for the user. There are 2 permission

levels defined. Both levels (level 2 and level 3) are basically the

same, the only difference is that for level 3 no water temperature

settings are possible (see table below).

By default  no  level is defined so  all  buttons  and  functions are

operable.

The  actual  permission  level  is  determined  by field  setting.  For

permission  level  2,  set  field  setting  [0

-

00]  to 2,  for  permission

level 3, set field setting [0

-

00] to 3.

Once the field setting is set, the chosen permission level is not

yet  active.  Enabling  the  selected  permission  level  is  done  by

simultaneously pressing buttons 

 and 

 immediately

followed by simultaneously pressing buttons 

 and 

, and

keeping all 4 buttons pressed for at least 5 seconds. Note that

no indication on the user interface is given. After the procedure

the blocked buttons will not be available anymore.

Deactivating the selected permission level is done in the same

way.

 Room temperature compensation value

If needed, it is possible to adjust some thermistor value of the

unit by a correction value. This can be used as countermeasure

for thermistor tolerances or capacity shortage.

The  compensated  temperature  (=  measured  temperature  plus

compensation value) is then used for controlling the system and

will  be  displayed  in  the  temperature  read-out  mode.  See  also

"[9] Automatic  temperature  compensation"  on  page 21

  for

compensation values for leaving water temperature.

  Status:  defines whether  the  ON/OFF  instruction  can  be

used in the schedule timer for space heating.

Refer  to  the  operation  manual  for  details  how  to  program  the

schedule timer.

The  schedule  timer  for  space  heating  can  be  programmed  in

2 different  ways:  based  on  the  temperature  set  point  (both

leaving water temperature and room temperature) and based on

the ON/OFF instruction.

In the following tables both methods on how to interpret the schedule

timer are shown.

INFORMATION

Changes  made  to  a  specific  field  setting  are  only

stored when the 

 button is pressed. Navigating to

a new field setting code or pressing the   button will

discard the change made.

The field settings are grouped by their field setting first

code.

For example, field settings [0

-

00]; [0

-

01]; [0

-

02]; [0

-

03]

are defined as "Group 0".

When  different  values  are  changed  within  the  same

group, pressing the 

 button will save all the values

changed within this group.

Be aware of this when changing field settings within

the same group and pressing on the 

 button.

INFORMATION

Before  shipping,  the  set  values  have  been  set  as

shown  under 

"8.4. Field  setting  list  for  Installation

Manual" on page 22

.

When  running  through  the  field  settings  you  may  notice

that  there  are  some  more  field  settings  as  there  are

mentioned  in  the
