value setting
131 °F 95 °F The internal enclosure temperature setting is
preset at the factory to 95 °F (35 °C) and may be
altered within a range of 68 – 131 °F (20 –
55 °C).
60 99 To enable filter mat monitoring, the display
(= off) should be set to a minimum of 10 K above the
temperature difference shown in programming
mode "Fi"; filter mat monitoring is disabled at the
factory (99 = off).
Not applicable for NEMA 3R/4 units!
19 0 See section 6.1.8 "Setting the master/slave
identifier"
1 0 The temperature display can be switched be-
tween °C (0) and °F (1). The LED displays the
current unit of temperature.
10 5 The cooling unit is preset in the factory to a
switching hysteresis of 5 K. This parameter
should only be changed in consultation with us.
Please contact us for advice.
15 5 If the internal enclosure temperature exceeds
the set value by more than 5 K, then error mes-
sage A2 (internal enclosure temperature too
high) appears on the display terminal. If neces-
sary, the differential may be altered here within
the range of 3 – 15 K.

15 0 This parameter allows you to change the "22"
