Changing the settings
Opening the hinged control panel
cover causes the operation-control
module to switch automatically to In-
formation and Programming mode.
The operating controls are assigned a
new significance (which can be seen
from the printed designations which will
now appear beneath the keys).
All entries can be made on the basis
of the same principle
1. Open the hinged cover on the front
of the controller; the controller
switches to INFO mode. The three
keys are then assigned the function
printed on the inside of the hinged
cover.
2. Choose the required parameter of
the current level or another level
with keys +/-.
3. Press the Programming key .
4. If you press key and have se-
lected a lower operating level
-> continue at Point 2!
5. If you press key and have se-
lected a setting, the controller
changes to Programming mode
(Programming indicator

).
6. The parameter value can be
changed with keys or .
7. Press key again; this saves the
new value.
8. If you close the hinged cover before
pressing key , this quits Pro-
gramming mode. The controller
switches to the standard display
(boiler temperature and time). The
changed value is not saved.

ating level by pressing key and
selecting the "RETURN" function.

Operating levels
After you open the hinged control panel
cover (Info mode), you can choose six
different operating levels with the
+/- keys. You can activate the selected
level by pressing the Programming
key.
Heating Prog1 / Heating Prog2
The BM allows entry of two heating
programs between which the user can
select.
! If switching time entry in blocks (Mo-
Fr, Sa-Su, Mo-Su) is activated, the
current switching times of the first
day of the block are displayed. The
display does not show the switching
times of the entire block. If you acti-
vate a switching time with the Pro-
gramming key (Warning triangle
 ) and then save the value by
pressing the Programming key
again. All switching values in the
block are overwritten by the switch-
ing values of the first day in the
block!
Recommended procedure
1) Enter all heating times for the pe-
riod Monday-Sunday (overwrite all
switching times of the week!).
2) Enter different switching times for
the corresponding days.

Parameter
Room sensor adaptation
The actual display can be varied by
±5 K in order to adapt the room tem-
perature display to the installation con-
ditions or other thermometers. The cor-
rected display value is used in the
calculations for all relevant functions.
Display
This parameter allows you to set
whether the current desired room tem-
perature is shown on the display.
Warm-up optimisation
Warm-up optimisation determines the
optimum advance time of start of
heating. The time advance ensures
that the heated rooms have reached
their desired temperature at the switch-
on times of the heating times.
Display: Last time advance required
Setting: Maximum time advance
Control I/0 <=> Proportional
Selection between two-point and pro-
portional control.
CONTROL I/0
Heating mode starts if the actual tem-
perature drops below the room tem-
perature by the displayed amount [K].
If the temperature is exceeded by the
amount [K], Heating mode ends. A
minimum switch-on/switch-off time can
be set with the delay setting.
PROPORTIONAL control
Heating mode is switched on for a per-
centage (50 %) of the adjustable cycle
time as a function of the deviation be-
tween the measured and desired tem-
perature of the room. The hysteresis
setting allows you to set an allowable
deviation from the desired tempera-
ture. This avoid short On times of the
boiler.
CONTROL OFF
No control function. The relais switches
only time dependent.
Heating/Cooling
The controller can also be used for
controlled cooling of rooms. If the
"Cooling" function is selected, the con-
nected cooling system is closed if the
desired temperature is exceeded by
the set hysteresis and is opened if the
actual temperature drops below the
desired temperature. In Proportional
mode, the relay is also switched as a
function of the control deviation. The
greater the set desired temperature is
exceeded at the instant of computa-
tion, the longer the cooling system re-
mains active.
Telephone switch/window contact
Telephone switch: The controller
switches to Heating mode  for as long
as the contact between terminals 3/4 is
closed.
Window contact: The controller
switches to Frost-protection mode -
for as long as the contact between
terminals 3/4 is interrupted.

Temperatures
Room temperature
This parameter allows you to program
the required desired room temperature
for the three heating times. The en-
tered value is set by the control on the
basis of the integrated room sensor.
ECO-TEMP
The reduced temperature or economy
temperature represents the tempera-
ture to which the system stabilises out-
side the heating times, e.g. during the
nighttime or during ECO mode.
Holiday
You can use the controller’s Holiday
program during the holiday period. The
duration of the holiday and the holiday
start are entered in days. The Holiday
program is always activated at 12.00
hours and always ends at 24.00 hours
of the last day of the holiday.
! If the holiday period is entered be-
fore 12.00 hours, the Holiday pro-
gram starts on the day of entry (S-
HOLIDAY=00; with S-HOLIDAY=05
in 5 days). If the holiday period is
entered after 12.00 hours, the pro-
gram starts on the next day at 12.00
hours. It thus also ends one day
later.
The controller switches to Standby
mode during the holiday. The Holiday
symbol is shown on the display. Holi-
day mode is terminated by operating
the Program switch.
! Please check batteries!

Battery change
 When the batteries reach a low
charge state (M), the system
switches to Heating mode. (Relay
contact is closed -> burner /
pump is on resp. valve is open).
! Always dispose of spent batteries
properly (spent battery collection
point).
Swivel upper part of controller upwards

within 2 minutes. If the battery change
should last longer, press the Reset
button and reset time and weekday
(see Reset function). Then re-engage
the top section at the upper edge of the
