USER MANUAL: SR 200.R10/1
User manual
This electronic room thermostat. serves for two-step temperature-
dependent On/OFF control of heaters, zone valves, storage
heatings etc. in dry, closed rooms.
1. Operating elements
1. Knob „comfort temperature“
2. Knob „temperature setback“
3. Key „RESET“
2. Function
The SR 200.R10/1 measures the ambient temperature by means
of an internal sensor. The output is a floating
doble-throw contact. A seven-day timer controls the heating and
temperature setback periods in the automatic mode.
You can select between automatic-, heating-, temperature
setback, frost protection and „off“ by means of the keys. An
indicator at the left part of the display shows the relay position.
2.1. Comfort temperature
The desired comfort temperature (5 bis 40°C) is selected at the
upper knob (1). The corresponding value is indicated at the right
part of the display instead of the actual temperature. Three
seconds after the last movement of the knob the thermostat
shows the actual temperature automatically again.
Hint:
A change of the comfort temperature results in a change
of the setback temperature by the same value, as the
temperature setback is interconnected relatively to the
comfort temperature.
(However, a change of the setback temperature does not
result in a change of the comfort temperature.)
2.2. Temperature setback
The temperature setback can be set at the lower knob (2): It is
indicated absolutely in the right part of the display. Three
seconds after the last movement of the knob the thermostat
again shows the actual temperature.
Caution
:
In order to avoid freezing the setback temperature
cannot be adjusted below +5°C.
In order to avoid freezing the setback temperature cannot be
adjusted below +5°C.
2.3 Frost protection
The frost protection temperature is fixed at 5 °C. This temperature
step can be polled by pressing both keys + and –. at the same time.
The frost protection cannot be reached over the timer
programme resp. in the cooling mode. The setback relay is not
controlled.
2.4 Off
If you press
and + at the same time the thermostat can be
switched off. On the right part of the display there isn’t any step
indicator now. The thermostat continues measuring the actual
temperature, however, the relay isn’t controlled any longer.
3. Clock
The clock is a seven-day-timer with approx. 15 minutes battery
reserve power. It offers 16 programme positions by means of
which you can programme 112 switching poins.
3.1 Time setting
The time can be set after the key
has
been pressed for 3 seconds or after a new
start following a reset. Each flashing value
can be changed
MO DI MI DO FR SA SO
with + und — keys.You can reach the next setting point with
„SET“ (hours -> minutes -> day). As soon as you confirm the day
with „SET“ the timer is started to the second and the thermostat
goes back to the operating mode out of which the menu „time
setting“ was polled. A timer which hasn’t been set yet is indicated
flashing.
3.2 Timer programming
The timer programme can be entered by a
short pressing of „PROG“. The display
shows programme position (P01-P16),
prevailing time and the days, at which
MO DI MI DO FR SA SO
the corresponding temperature step (comfort step or setback step,
indicator at the right side) is valid. The prevailing flashing value can
be changed with + and — . The next menu points can be reached
with „SET“ (programme position -> time -> days -> temperature
step). By pressing „PROG“ when the programme position number
is flashing the thermostat goes back to the mode, out of which the
menu (setting of time programme) was polled. Ineffective
programme positions are marked by ––:–– instead of showing the
time.
Works standard setting is as follows:
MON – SUN: from 6:00 a.m. comfort temperature
MON – FRI: from 10:00 p.m. temp. setback
SAT – SUN: from 11:00 p.m. temp. setback
3.3 Manual-Key
The
-key enables the user to change the present temperature
in the automatic mode. The selected temperature step is shown
with the indicators at the right part of the display. This function is
cleared with the next programme position.
4. Selecting operating mode
The operating mode can be selected by
means of the left three keys. Here, you
can choose between automatic
mode
, comfort mode
(long-
MO DI MI DO FR SA SO
term), temperature setback mode (long-term), frost protection
and Off
. The operating modes „“off“ respectively „frost
protection“ can hereby be reached by simultaneously pressing
the left upper - and middle key respectively the lower - and
middle key. The selected mode is shown by the indicators at the
right part of the display. In the automatic mode a second
indicator shows the valid temperature step. If the thermostat is
operated in the cooling mode, frost protection cannot be polled.
5. Setting of control parameters
By pressing PROG for three seconds you
reach a menu whithin which different
control parameters may be set. The left
part of the display shows the
MO DI MI DO FR SA SO
parameter and the right part shows the prevailing value
respectively the position. The value can be changed with + and
— . The next parameter can be reached with SET. With
confirming the last parameter by „SET“ the thermostat goes back
to the operating mode, out of which the menu „setting
parameters“ has been polled. The individual parameters have
the following meaning:
