This parameter* is used to set the value below which the air temperature must fall for a
period of at least 18 hours. If this condition is fulfilled and the temperature rises sharply,
there is a risk of freezing rain. Make sure that the base temperature is set lower than the
ground temperature value for the 18-hour period. Otherwise the temperature will never fall
below the value for the 18-hour period and the freezing rain warning will not work.
The OVERRULING parameter is used to configure the relevant logic input. If the parameter
is set to 'OFF' the input is not evaluated by the control device. The control device is not
affected.
In the 'ON' setting the control device cannot switch the heating on for 10 min. if the input is
or was short-circuited. This prevents peakloads in buildings. If the input is still short-
circuited or has short-circuited again after 10 minutes have elapsed, the device cannot turn
on the heating for another 10 minutes.
If the device is set to 'CONTROL' the heating output is remote controlled. If the input is
short-circuited, the control device switches the heating off. If the input is open, the device
will switch on the heating in any event.
The sensor values of the ice indicator are displayed but not evaluated.
This parameter allows you to select what status the heating timer should assume in the
event of a fault. The 'OFF' setting is recommended for all energy sensitive applications,
whereas the 'ON' setting should be selected for safety applications.
This menu option indicates the heating time in hours (H) and minutes (M).

5.1. What to do during set up
When the device is first put into operation it carries out an auto-test. During this test the
display indicates, "POWER-UP TESTS". If the device finds a fault during this test, it displays
a number on the second line of the display. Otherwise the device goes into the standard
operating mode.
* The air temperature is indicated only when "local detection" is selected.
