10.2.6  Rain Gauge Settings 
 
Heater mode:  The device can be configured for heating in different operating modes. 
Configure as ‘automatic’ in normal operating mode. You can find a precise 
description of the operating modes on page 32. 
Followup time precipitation type: for this time (in seconds) the detected precipitation type is 
shown; to cover all events, this time must be adjusted to the poll rate. 
Note: All other parameters, especially those in the ‘Rainfall calibration data’ tab‚ may only be 
changed after consultation with the manufacturer, as they have a major influence on the 
functioning and accuracy of the sensor. 
10.2.7  Energy Management 
 
With the button "Maximum energiesaving", the power consumption of the device is reduced 
by the following action: 
  The ventilation of the temperature / humidity unit is switched off 
  All heaters are switched off 
  The rain sensor is not working continuously; per minute, the sensor is activated for one 
second, if then precipitation is detected, it remains until the end of the event turned on, 
otherwise it is deactivated after the one second again. 
Note: This setting has the following restrictions: 
  With the fan switched off deviations in temperature and humidity measurement can occur 
by solar radiation. 
  Winter operation is not possible in this operating mode because any icing might prevent 
the correct operation of the rain sensor or wind meter. 
  The rain detection may be delayed up to 2 minutes. Short events are possibly not 
detected. Thus, deviations in the accuracy of the precipitation quantity are possible. 
  For maximum energy saving, a device with version 025 or higher is required (last position 
of the serial number).
