20°C 55°C 35°C The internal enclosure temperature setting is
preset at the factory to 35°C (95°F) and may be
altered within a range of 20 – 55°C (68 – 131°F).

2 Fi Filter mat monitor-
ing 10°C 60°C 99
(= off) To enable filter mat monitoring, the display
should be set to a minimum of 10 K (18°F)
above the temperature difference shown in pro-
gramming mode "Fi"; filter mat monitoring is dis-
abled at the factory (99 = off).

tifier 0 19 0 See section 6.1.8 "Setting the master/slave
identifier".
4 CF Switch between
°C/°F 0 1 0 The temperature display can be switched be-
tween °C (0) and °F (1). The LED displays the
current unit of temperature.
5 H1 Setting for switch-
ing difference (hys-
teresis) 2 K 10 K 5 K The cooling unit is preset in the factory to a
switching hysteresis of 5 K (9°F). This parameter
should only be changed in consultation with us.
Please contact us for advice.

6 H2 Differential for error
message A2 3 K 15 K 5 K If the internal enclosure temperature exceeds
the set value by more than 5 K (9°F), then error
message 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 (5 – 27°F).

27 PSO Changing the au-
thorisation code 0 15 0 This parameter allows you to change the "22"
authorisation code (factory setting).
The new code results from the sum of 22 +
PSO.
