Comfort indicator
The comfort indicator reflects the climate in the room (ratio of temperature to humidity). You can find a table
of values for the display areas in section 15 on page 56.
The comfort indicator displays three different smiles:
10. Changing battery
Depending on which batteries or accumulators you use, the replacement interval can be very diffe-
rent. High-quality alkaline batteries keep the longest, accumulators for cheap zinc-carbon batteries
require more frequent changing.
a) Base station
If the battery flat symbol appears in the display (
•
Always replace the whole set of batteries.
•
Do not mix full with "half-full" batteries".
•
Always use four batteries of the same type and manufacturer.
•
Do not mix batteries with accumulators.
•
As already mentioned, accumulator operation is possible, the durability is, however, appreciably lower
than with batteries.
•
For changing the batteries, proceed as described in section 7. c).
Please observe the following:
After replacing the batteries, all data, values stored in the base station (e.g. time, date etc.) are delet-
ed and have to be entered again.
b) Combination sensor, outdoor sensor
When the display of the sensor concerned fails for more than 24 hours, the batteries are to be replaced with
new ones as described in section 7. a) and b).
Check as whether there is possibly some disturbance in the radio transmission which is the cause
for the failure of the data transmission. In this case also, there will be no indication in the display of
the base station.
The cause could be, for example, a metal object in the radio path (e.g., a parked vehicle).

), the batteries have to be replaced by new ones.
b) Operation
Selecting indoor temperature display
In normal operation, the indoor temperature and internal humidity are displayed in the display field
"INDOOR".
By repeatedly pressing the "IN" key, you can switch between:
•
indoor temperature
•
respective dew point
Selecting outdoor temperature display
In normal operation, the indoor temperature and internal humidity of the selected outdoor sensor are dis-
played in the display field "OUTDOOR".
By repeatedly pressing the "OUT" key, you can switch between:
•
outdoor temperature
•
respective dew point
•
temperature measured (wind chill)
Selecting outdoor sensor
In the display field "Sensor", the outdoor sensor selected at the moment concerned is displayed together
with its sensor number. Only active (in the synchronisation phase) sensors are displayed.
To select the outdoor sensors or combination sensors, press the "SENSOR" key so long until the desired
sensor number appears:
•
for outdoor sensors 1-8, the sensor number concerned (1-8) is displayed
•
no sensor number is displayed for the combination sensor, the overlay "SENSOR" (alongside the outside
humidity) disappears.
Selecting rain quantity display period
By repeatedly pressing the "RAIN" key, you can switch between:
•
display for the last hour
•
display for the last 24 hours
•
display of the total quantity since the last clearance of the rain quantity after inserting the batteries.
Deleting total rain quantity
Press "RAIN" key for approx. 2 seconds. After releasing the key, the total rain quantity is deleted.
Displaying MIN-/MAX figures
For the measurement figure of the indoor/outdoor temperature and indoor/outdoor humidity, the minimum
and maximum figures reached since the last clearance of data are stored.
Only the MAX figures are stored for the wind velocity and rain quantity measurements.
The point of time and date of incidence of the extreme value are also stored for all figures.
Pressing the "MIN/MAX" key switches between the display of the minimum values, the maximum values and
the normal display. Proceed in retrieving the stored date as follows:
