Parameter P28 represents the “alarm activation delay” in minutes; the
low temperature alarm (E05) is activated only if the temperature remains
below the value of P25 for a time greater than P28. The alarm may 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.

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 and E05 are active, the buzzer can be muted by pressing
Prg/mute. The display remains active.
5.2.6 Direct/reverse with changeover from digital input
1 (parameter 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.
5.2.7 Direct with set point & di erential, changeover
from digital input 1 (parameter 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.

5.2.8 Reverse with set point & di erential, changeover
from digital input 1 (parameter c0=8)
The controller always operates in “reverse” mode, based on St1 when
digital input 1 is open and based on St2 when it is closed.
