B1 Probe 1
Parameter P28 represents the “alarm activation delay”, in minutes;
with reference to probe 1 the low temperature alarm (E05) is activated
only if the temperature remains lower than the value of P25 for a time
greater than P28. The alarm may be relative or absolute, depending on
the value of parameter P29. In the former case (P29=0), the value of P25
indicates the deviation from the set point and thus the activation point
for the low temperature alarm is: set point - P25. If the set point changes,
the activation point also changes automatically. In the latter case (P29=1),
the value of P25 indicates the low temperature alarm threshold. The low
temperature alarm active is signalled by the buzzer and code E05 on the
display. The same applies to the high temperature alarm (E04), with P26
instead of P25. Likewise parameters P30 to P34 refer to probe 2.

The low and high temperature alarms are automatically reset; if there
is an alarm active on the control probe, these alarms are deactivated
and monitoring is reinitialised.
When alarms E04/E15 and E05/E16 are active, the buzzer can be
muted by pressing Prg/mute. The display remains active.
5.3.6 Mode 6: Direct/reverse with changeover from
DI1 c0=6
The controller operates in “direct” mode based on St1 when digital input
1 is open, in “reverse” based on St2 when it is closed.

For models W & Z the activations of the outputs are equally distributed
inside the di erential set (P1/P2).
Parameter c29 is not active in mode 6.
5.3.7 Mode 7: Direct with set point & di erential,
changeover from DI1 c0=7
The controller always operates in “reverse” mode, based on St1 when
digital input 1 is open and based on St2 when it is closed.
