0.5K increments. (FS = 28.0°C)
P-BAND
Proportional band, heating and cooling. Range
0.5...99.5K in 0.5K increments. (FS = 5.0K)
I-TIME
Reset time. range 0...999 seconds. (FS = 0)
N.B.
the range is 999 and not 99.9.
N.B.
0 = P-control, no integration factor.
CAL
Temperature reading calibration. The sensor
value can be corrected ±3K in 0.1K increments.
N.B.
Use with care. All units are factory calibrated.
Presence detection. ON / OFF. When active, one
of two symbols will be displayed to indicate
which of the two running modes is active.
Man in rectangle = Occupied mode
Man outside rectangle = Unoccupied mode
Setpoint offset
During normal running the configured sepoint value can be
offset ±3K in 0.5K increments.
Klick on either the + button or the - button and the present
displacement will be shown. Change the value using the
+ button or the - button to increase or decrease the value. The
ALD24A1 will automatically revert to normal running display
after 3 seconds of button inactivity.
