1. Operating instructions
• The direct select keys for ON/OFF, holiday and party settings, operating mode switchover
and the entry of programs enable to manipulate the device in a very simple manner, even
after longer operating pauses.
• The device is, in order to gain a fast overview of the actually adjusted values, equipped
with a separate information mode, the selection of which is possible also directly by a key.
In this mode, no values can be misadjusted in error.
• The adjusting knob with the °C imprint on it enables to set and read the desired set
temperature in an uncomplicated manner.
• The setting of the times for both comfort and ECO mode operation has been modelled
on the example of shift segments or so-called “shiftable stops” (wellknown from the setting
of mechanical switch clocks). The term “handling without studying” best describes the idea
behind this concept.
• Pressing, during the entry of data, one of the keys
or
longer, activates a scroll
function.

Installation intructions
Then press the
key to enter the weekday programs. To do so, select the
corresponding weekday fi rst. For Monday, the number 1 appears fl ashing on the display.
The selection of all other weekdays is made by means of the
and
keys.
After confi rmation of the selected weekday with the
key, the shift segments
or “shiftable stops” can be set (beginning at 0.00 o’clock). In addition to the time to be
adjusted, the position at which the related “shiftable stop” can be set starts fl ashing too.
Any actuation of the
key sets a shiftable comfort temperature stop (equivalent to a
quarter of an hour), while actuating the
key enables to advance by another quarter
without setting any shift segments. Pressing the
or
key longer activates the scroll
function. Repeating the entry step and replacing it by a new one can correct misentries.
This can be realised without leaving the actually selected weekday simply by overstepping
the 0.00 o’clock marker and repeating the related entry step.
After confi rmation with the
key, the next weekday starts fl ashing for selection.
After selection of the next day by means of the
key, the copy function is enabled
and the system suggests continuing with the program that has been entered for the
previous day. The suggestion can either be imported by means of the
key or another
program be entered instead. After confi rmation with the
key, the next weekday fl ashes
for selection, etc. The copy function is stopped when selecting Saturday. In this case, the
program chosen for Saturday is again suggested by the system for use on Sunday. Once
the radio room temperature sensor has been adjusted to a heating & cooling system, the
weekday programs for the operating mode “cooling” are extending the entry range.
Regarding other setting options, please see section 3., “Adjustment functions”.

,
,
The device has 6 direct select keys in total that enable to select and quit the desired func-
tion. All keys are deactivated that are not required while remaining in one of the functions.
The selection of another function is enabled only after having quitted the currently selected
function.
2.1. Entry of programs
The program entry function serves for the adjustment of the ECO temperature, the time,
the date and the different weekday programs. Once activated, it works according to the
principle that is commonly known as „compelled guidance“. When confi rming a certain
value by actuating the
key, the display will change over to the next entry to be made.
The letter “P” is being displayed to indicate the active state of the function. Depending
on the entry step to be made, the function allocated to the next value to be entered is
being represented through easily comprehensible symbols while the fi elds for the value to
be entered are fl ashing. When confi rming the Sunday program, the program entry mode
is being quit all automatically. Actuating the direct select key
at any time can also
terminate the program entry. Once no key is actuated for any longer than 2 minutes, the
entry mode function is terminated all automatically. Entries will be imported only after
confi rmation with the
key. After termination of the program entry function, the display
changes again back to the previously indicated operating display.
Entry procedure:
Press the direct select key
fi rst, and then enter the ECO temperature (the logogram
„ECO“ appears on the display). Depending on the adjustment settings, the actually
entered ECO temperatures are either stored as absolute values within a range from 5
to 29°C (factory setting 17°C) or as set value-dependent values (temperature decrease
during operation in heating mode -1°... -6° (heating OFF) and temperature increase during
operation in cooling mode 1°... 6° (cooling OFF) factory setting: heating -2°, c2°).
After confi rmation with the
key, the clock time can be entered (the clock symbol
is shown on the display). Enter the hours fi rst and then the minutes.
After confi rmation with the
key, the date can be entered (the letter „D“ appears
on the display). First enter the year, then confi rm with
. After that, enter both the
corresponding month and weekday.
2.2 Heating system, climate conditioning or cooling system indication
If the sensor has been adapted to a heating system (factory setting) the heating symbol
is being displayed permanently during operation in all three operating modes, i.e. comfort,
ECO and automatic mode. If it has been adapted to a cooling system, the cooling symbol
is being displayed permanently. If adapted to a climate conditioning system (heating &
cooling), both symbols
are being displayed while operating in automatic mode. In
this mode, the program indication and the corresponding symbols will alternate every 15
seconds from heating mode to cooling program indication and vice versa. If deactivating
the program indication during operation in adjustment mode (corona symbol), the symbols
and are also indicated during operation in automatic mode.
2.3 Switchover between the operating modes “automatic”
, “comfort”
and
“energy-economizing mode” (ECO)
This function has been implemented for switchover between the three operating modes
“automatic”
, “comfort”
and „energy-economizing“ (ECO). Special shift segments,
so-called shiftable stops (known from mechanical switch clocks) that have been arranged
in a corona-like manner represent the actually adjusted operating mode on the display.
Shift segments (“shiftable stops“) indicate the comfort mode times visibly, while energy-
economizing times are indicated through missing segments. The operating modes
“automatic“ and “energy-economizing“ are indicated additionally by the clock program
symbol
and the logogram “ECO“. The operating mode “comfort“ is exclusively indicated
through the circumferentially arranged corona of shiftable stops. Once the device operates
in comfort mode
, the controller controls all operations permanently in dependence
on the comfort temperature value that has been set at the adjusting knob beforehand. If
operating in energy-economizing mode (ECO mode), the controller regulates all operations
subject to the ECO temperature value entered beforehand. If operating in automatic mode
, the system toggles all automatically between comfort and energy-economizing mode
operation.
2.4 The ON/OFF function
Actuating the
key deactivates the control system. When actuating the key
again,
the control system returns to the previous operating mode. Once the control system is in
OFF condition, “OFF” is being indicated on the display in order to delimit this condition
against a radio room temperature sensor supply voltage failure due to depleted batteries.
Once it has been deactivated, the system nevertheless ensures frost protection (5°C). The
valve and pump protection remains likewise active if activated in the adjusting menu.
2.5 Holiday function
The holiday function has been implemented for energy saving purposes. It serves for
the economization of energy during longer absences and for the timely heating up to
the desired temperature prior to the time the return of a person was scheduled. When
actuating the
key, the date of the next day is being displayed. After the setting of the
return date by means of the keys
,
and
, the holiday time temperature is being
displayed (factory setting 17°C). This holiday time temperature too can be changed within
a range from 5 to 30°C. After confi rmation of the holiday time temperature by means of the
key, the holiday function is rendered active and both the return date and the holiday
symbol
are being displayed. Actuating the direct select key
at any time cancels
the holiday function. If not terminated this way, the function is cancelled all automatically
at 0.00 o’clock of the actually entered return day. Once the holiday function has been
cancelled, the control operations are being continued in the previously selected operating
mode and the related indications displayed again.
2.6 Information function
The info function enables to indicate all actually adjusted values. No inadvertent
misadjustment can take place while doing so. Once this function is active, the symbol
is being indicated on the display. After actuation of the
key, the actually adjusted
ECO temperature is indicated fi rst. Actuating the keys
and
enables to inquire all
actually adjusted values. Within this function, values can neither wilfully nor inadvertently
be misadjusted. Actuating the direct select key
at any time cancels the info function. If
not terminated this way, the function is cancelled all automatically 2 minutes after the last
keystroke was made. The selection of the info function does not impair any of the control
operations currently performed. Once the info function has been cancelled, the display
returns to the previously indicated operating screen.
