Moisture
limit xx
Displays the set moisture limit for the selected sensor; adapt setting
with "Set" and then "+" / "-"; save with "Set".
Setting "-x" = the moisture limit set in the "Configuration" menu will be
used.

Error codes
In case of a failure, the menu "Show Status” will display an error code for the detector or the sensor(s). The
value "0” indicates that currently there is no error. The error codes are explained in the following tables. If more
than one error condition is active at any one time the display will show the sum of the related error codes (e. g.
error 1 and error 4 active at the same time will cause an error code 5 to be displayed).
a) Ice and snow detector
Error code
Description
Possible cause
1
Slab/gutter temperature cannot be determined;
all active temperature sensors report
temperature measurement failure.
• see sensor error code 1 (slab/gutter sensors
only)
• internal detector failure
2
Outdoor temperature required but not available
(slab idle mode only);
outdoor temperature sensor reports
temperature measurement failure.
• see sensor error code 1 (outdoor temperature
sensor only)
• internal detector failure
4
Moisture cannot be determined;
all active moisture sensors report temperature
measurement and/or moisture detection failure.
• see sensor error codes 2 or 4 respectively
• temperature loop of affected sensor faulty
• internal detector failure
8
Configuration problem
• no sensor defined for temperature
measurement
• no sensor defined for moisture detection
• slab idle mode enabled but no valid sensor
defined for outdoor temperature measurement
Note: As long as a single sensor failure does not cause the entire ice and snow detection system to fail, this will
not be shown as a system error in one of the above error codes. In this case please check the error codes of the
individual sensors.
b) Sensors
Error code
Description
Possible cause
1
Temperature sensor faulty
• temperature detector inside the sensor faulty
• internal detector failure
• open loop or short circuit in sensor cable
2
Supply voltage prior to start of the last
moisture detection cycle not within the defined
voltage range; detection cycle was not started.
• detector supply voltage more than + 10 %
above rated voltage
• detector supply voltage more than - 15 %
below rated voltage
• internal detector failure
4
Last moisture measurement faulty
• supply voltage too low during last moisture
detection cycle
• open loop or short circuit in sensor cable
• moisture detector inside the sensor faulty
• internal detector failure
8
Internal failure during last moisture
measurement
• configuration problem
• internal detector failure
16
Internal failure during interval between two
moisture detection cycles
• current > 25 mA although no detection cycle
is active on any sensor
• internal detector failure
32
Measurement is not executed because
measurement values are not meaningful or in
order to avoid damage to the sensor.
• temperature too high (> 30 °C) when
measurement cycle begins
64
Measurement is aborted to avoid damage to
the sensor.
• temperature too high (> 55 °C) during the
measurement
