* Setting internal parameters.
Next to the adjustment of the setpoint, some other internal settings are possible, like differential,
sensor-offset, setpoint range.
By pushing the
DOWN
key more than 10 seconds, you enter the 'internal programming menu'. In
the left display the upper and lower segment are blinking. With the
UP
and
DOWN
keys the
required parameter can be selected (see table for the parameters). If the required parameter is
selected, the value can be read-out by pushing the
SET
key. Pushing the
UP
and
DOWN
keys
allows you to change the value of this parameter.
If after 20 seconds no key is pushed, the
ALFA(NET) 13
changes to it's normal operation mode.
* Parameters ALFA(NET) 13.
