4. STARTING, USER INTERFACE AND BASIC FUNCTIONS

Before starting the humidifi er, check:
□ water connections: in the event of water leaks, do not start the
humidifi er before having restored the connections;
□ electrical connections

4.1 Starting

See chap. Electrical connections
1 The humidifi er, once powered and enabled for production (remote
on-off /humidistat, terminal M14), is ready for operation
2 If there are no other external connections, the humidifi er will start, and
operation will only stop if the enabling signal (M14) is no longer present.
3 If TH humidity probe (optional) is connected to terminal G, the
humidifi er will operate until reaching the humidity set point (default
50%rH). See chap. Operating principles

4.2 Shutdown/Standby

1 To switch the humidifi er off , disconnect power
2 The humidifi er goes into standby when:
•
the remote ON/OFF contact is open
•
TH probe is fi tted and the humidity set point has been reached
•
the ON/OFF contact is open and serial enabling is set to 0 (see
chapter Humidifi er control via network)
•
a modulating signal is used (optional card) and there is no
request
When the humidifi er is in standby, the unit is emptied
automatically. When in standby the fan stays on for 5 min.

4.3 Autotest

Whenever the humidifi er is fi rst started (from off ), if enabled and humidity
production is required, a test cycle is run. A complete fi ll and drain cycle
is performed, during which the level sensor is monitored; if the test is
successful, regular atomized water production will start. If the test fails,
production is disabled (see the alarm table).

4.4 ON/OFF switch lights

The ON/OFF switch has 2 lights: white and red:
WHITE LIGHT
Steady Humidity production
Flashing slowly* Stand-by or Set point reached
Flashing quickly* Autotest or wash
*Flashing slowly: 1s ON and 1s OFF
** Flashing quickly: 0.2s ON and 0.2s OFF
The red LIGHT means an alarm is active. See Alarm table for information
on alarms.

4.5 Disabling

The humidifi er can be disabled in 2 diff erent ways:
•
Opening contact M14.1 and M14.2 (enabling signal)
•
There are active alarms.

4.6 Reset tank hour counter

The humidifi er is fi tted with an hour counter that records operation.
After a set number of hours (5000), a signal is activated to indicate
maintenance should be performed on the tank and operation of the
piezoelectric elements checked (see ...). To reset the hour counter at any
time, proceed as follows:
•
Switch the humidifi er OFF;
•
Close the water-tap and wait for the tank to empty completely;
•
Disconnect the Lumberg (see Fig. 4.a) connector on the control board;
•
Open the ON/OFF contact;
•
Switch the humidifi er (with the Lumberg connector disconnected
from the control board). White and red lights will be fl ashing;
•
Close the ON/OFF contact, white and red lights remain on steady;
•
Switch the humidifi er OFF;
•
Plug the Lumberg connector (see Fig. 4.a) onto the board, making sure
it is inserted in the correct direction;
•
Switch the humidifi er ON.

4.7 Automatic washing

The humidifi er automatically runs a washing cycle at intervals in
operating time set by parameter b1 (default 60 minutes, parameter b0
can be used to convert this value into hours, see b0 parameter table).
The washing cycle involves a complete drain cycle, a phase in which
fi ll and drain are activated together (default 1 minute, parameter b3) to
fl ush out any residues in the tank, a complete fi ll cycle and fi nally another
complete drain cycle.
During this operation, atomized water production is stopped.

4.8 Washing due to inactivity

If the humidifi er remains inactive (on but in standby) for an extended
period (parameter b2, default 24 hours) a washing cycle is performed, as
described in the previous paragraph. This cleans the tank of any residues
(e.g. dust) that may have accumulated during the period of inactivity.
Parameter b0 can be used to set the time when this washing cycle is
performed. By default, the washing cycle is run after 24 hours (continuous)
of no operation, i.e. the humidifi er is in standby. This is because the
humidifi er is normally connected to a reverse osmosis system, which
needs to operate frequently in order to avoid malfunctions. B0 (see
parameter b0 reverse osmosis) can be set so that the washing cycle is
performed when fi rst restarting after a period of continuous inactivity set
by b2.
