Maintaining the keys pressed makes increasing or
decreasing the value quicker. The new limit value
is automatically accepted after 20 sec. (back to sur-
veillance mode).

surveillance mode.
7.3 Temperature tolerance value :
Starting from the normal surveillance mode, press
and maintain the „UP“-key (2), then press
additionally the „M“-key (3). On the lower line of the
display, „tol“ is shown and the temperature toleran-
ce value shown on the upper display line can now
be altered with the „UP/DOWN“ keys (2/7).
This tolerance value determines the temperature
difference from the programmed limit value (see
7.1), at which the acoustical pre-alarm sounds.
The new tolerance value is automatically accepted
after 20 sec. or after having pressed the „M“-key (3).
The unit then switches back to surveillance mode.
