Detailed description

[0] Remote control setup

■

[0-00] User permission level

The remote controller 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] is 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 

pi

 and 

pj

 immediately

followed by simultaneously pressing buttons 

s

  and 

ba

, and

keeping all 4 buttons pressed for at least 5 seconds. Note that
no indication on the remote controller is given. After the
procedure the blocked buttons will not be available anymore.

Deactivating the selected permission level is done on the same
way.

■

[0-01] 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 

23

  for

compensation values for leaving water temperature and
domestic hot water temperature.

■

[0-03]  Status: defines whether the ON/OFF instruction can be
used in the schedule timer for space heating.

The schedule timer for space heating can be programmed on 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.

Operation example:  Schedule timer based on temperature set
points.

When setback function is enabled, the setback operation will have
priority over the scheduled action in the schedule timer.

NOTE

By default space heating based on temperature set
point (method 1) is enabled, so only temperature shifts
are possible (no ON/OFF instruction).

Advantage of this method is that you can simply switch
off the space heating operation by pushing the 

y

button without disabling the automatic domestic hot
water storage operation (e.g. during summertime
when no space heating is required).

Method 1

Space heating based on temperature set point

(a) For leaving water temperature and/or room temperature

During operation

During schedule timer operation the operation LED is lit 
continuously.

When pushing 
the 

y

 button

The schedule timer for space heating will stop and will 
not start again.
The controller will be switched off (operation LED will 
stop working).

However, the schedule timer icon will stay displayed 
which means that the domestic water heating stays 
enabled.

When pushing 
the 

r

/

p

 button

The schedule timer for space heating and domestic 
water heating along with the quiet mode will be stopped 
and will not start again.

The schedule timer icon will not be displayed anymore.
