•
the request from the external signal is greater than 10% or the humidity
/ temperature measured is less than the set point selected in steps 8/9
and 9/9 of the guided procedure;
•
the unit is in ON from the keypad and the zones are in RUNNING mode;
•
there an external signal that enables operation, i.e. the voltage-free
contact between M2.7-M2.8 on the c.pHC controller is closed;

5.8.2 Set
Fig. 5.e
The information on the Set screen depends on the selected control mode.
When control by probe has been selected, this screen is used to set the
zone humidity / temperature set point and the limit probe set point, if
used. Each set point is associated with the amplitude of the proportional
band inside which the unit modulates atomisation.
Example: set point = 50%rH and band = 5%rH means that atomisation in
the room will be modulated starting from 45%rH.

5.10 Alarms
If there are active alarms, these are shown on the corresponding screen,
accessible by pressing the dedicated button (triangle with exclamation
mark).
The ALARM button starts flashing when an alarm occurs: pressing the
button once displays the type of alarm.
The alarms are divided into three categories:
•
potentially dangerous alarms that automatically stop production,
forcing the unit off until they are reset (alarm code AB***);
•
signals that do not stop production (alarm code AL***);
•
warnings only logged in the notification centre, neither signals nor
alarms that stop production (alarm code WR***).
For some alarm events, together with the signal the alarm relay is
activated. When the cause of the alarm is no longer present:
•
the humidifier and the alarm relay are reset, either automatically or
manually (see Chap. 7.1 “Alarm List”);
•
the message displayed can only be cleared manually
Even if no longer active, the alarm status will continues to be shown until
the “reset display” button is pressed. Alarms that are still active cannot be
reset. If more than one alarm is active, the display indicates all of these in
sequence. From the alarm screens the log can be displayed by pressing
ENTER. For the complete table of alarms see chap. 10 "Alarm table".
