3. GENERAL DESCRIPTION
3.1 General description
humiFog Direct is a direct humidier for room installation. It consists
of a pumping unit (also called the cabinet) and a distribution system
(comprising blower units) to be installed directly in the room to be
humidied and cooled. The pumping unit is connected to the blower
units by high pressure hoses.
The cabinet is tted with a pump that delivers water at high pressure (70
bars) to the nozzles on the blower units, where it is atomised into very
ne droplets that evaporate spontaneously.
The cabinets are available in the single zone and two-zone version. The
latter can manage two independent zones, reading two separate signals
(from a probe or external controller).
For all models, the minimum ow rate that can be supplied by the pump
is 10% of its nominal ow rate. For this reason, it is recommended to
couple a distribution line that can atomise a ow-rate of water equal at
least to the minimum ow-rate delivered by the pump.
It is important to install the distribution system in a suitable environment
(in terms of volume, air change and operating temperature) so as to
ensure absorption of the atomised water. Carel can provide support for
calculating the required humidication load.
3.2 Operating principle
System operation is based on a request signal from a probe (temperature
or humidity) or external controller. When the operation consent is
enabled (remote ON/OFF) and at the same time there is a request for
humidication or cooling, the system opens the delivery solenoid valve
(see par. "Structure") and activates the pump, which pressurises the water
at high pressure (70bar). After having also opened the outlet solenoid
valve, the initial stage of operation begins, involving washing and lling
the line, after which, when the line is lled and pressurised, the nozzles
will start spraying water.
Modulation is available in PWM mode (pulse width modulation): the
controller alternates a time (set on the display) in which the outlet
solenoid valves are operation, thus atomising the water, with period in
which the outlet valves are closed and the bypass valve is open, thus
interrupting atomisation into the room.
The set point is managed directly by the electronic controller using a
proportional band (P+I) or an oset when reaching the set point.
On reaching the set point, the system stops and enters standby mode,
restarting when there is a new request. For this reason, the system should
be powered on at all times.

N.B. to manage the 230V - 60 Hz power supply a 230V-120V transformer
can be installed upstream and connected to the cabinet. The transformer
must be installed according to safety standards in force.
3.4 Hose part numbers
The high pressure hoses (OD = 10 mm, ID = 6.4 mm) are supplied by
Carel in dierent lengths. The part numbers available are listed below.
All the hoses have with M16x1.5 female couplings with O-rings, ideal for
direct connection to the cabinet and the blower units without needing
to use sealants. Each hose kit includes an M16x1.5 nipple to be used for
coupling dierent hoses together.
Stainless steel pipes can also be used to connect the blowers to the
cabinet. The recommended outside diameter is 10 mm. This solution is
the installer’s responsibility.
Carel recommends using hoses rather than pipes.

4. CABINET INSTALLATION
4.1 Positioning
As the pumping station is IP20, it must be located in a roofed technical
room, protected from rain, splashing, direct sunlight and any source
of heat. The temperature/humidity sensors required to control the
humidier must not be aected by misting and they must be placed
away from direct sunlight and any heat source.
The cabinet must be installed in an environment with a temperature
between 5 and 40°C.
Around 1 m clearance must be left in front of the cabinet to allow the
door to be opened and maintenance to be performed. At the sides, a free
space of about 0.5 m (on both sides) must be provided, in order to allow
for the hydraulic connections on the right and the electrical connections
on the left.
Fig. 4.a
4.1.1 Wall mounting
The cabinets can be wall-mounted or oor-standing.
In the event of wall mounting, it is recommended to use the metal frames
and screws supplied. See the distances shown in the following image for
drilling the holes and fastening the brackets.
Fig. 4.b
4.1.2 Floor-standing installation
For oor-standing installation, the unit needs to rest on a raised platform

4.2 Water connections
WARNING: electric shock hazard.
Before making the electrical connections, the appliance must be
disconnected from the mains power supply and must be prevented
from being powered on. Electrical disconnection must be veried by
measurement.
NOTE: observe the local regulations for connecting the system to the
drinking water supply (see VDI/DVGW 6023, DIN EN 1717 and DIN 1988-100).
4.2.1 Feedwater line
An expansion vessel should always be installed upstream of the cabinet,
so as attenuate variations in pressure in the feedwater line. It is also
suggested to install a mechanical lter on the feedwater line to the
cabinet (P/N ECKVESS050 for the lter vessel and P/N ECKFILT050 for the
lter cartridge). Finally, an on-o ball valve should be installed on the line
upstream of the cabinet, so as to allow for any maintenance operations
on the water circuit downstream.

4.2.2 Feedwater characteristics
humiFog Direct requires demineralised water, so as to ensure:
• minimum maintenance;
• no blockages of the nozzles;
• no dust (the droplets that evaporate will not leave mineral salts in the
environment);
• improved hygiene.
The use of demineralised water is also required to comply with standards
UNI8883, VDI6022 and VDI3803.
humiFog Direct must only operate on demineralised water that falls
within the limits listed in the following table. Normally, these values can
be obtained by reverse osmosis or nanoltration of the feedwater.
Ion exchange softening is not recommended, as it is ineective in
removing salts and as it can cause microbial contamination.
Temperature 5 ÷20°C (41÷68°F)
Specic conductivity 25 ÷ 80 μS/cm
ph 5.5 – 8.5
Total hardness (TH) 0 ÷ 25 mg/l CaCO3

Iron + manganese (Fe + Mn) 0 mg/l
Silicon dioxide (SiO2) 0 ÷ 1 mg/l
Chlorine ions (Cl-) 0 mg/l
Calcium sulphate (CaSO4) 0 ÷ 5 mg/l
With regard to microbiological parameters, the water used must be
of drinking quality. If it is not possible to keep the water temperature
below 20°C (68°F), appropriate measures must be provided for in the risk
assessment document by the person in charge of running the system.
4.2.3 Cabinet drain connection
The drain point located at the bottom of the cabinet must be connected
externally (3/4" GAS F tting) to an open discharge with drain trap.

5. DISTRIBUTION SYSTEM INSTALLATION
5.1 Blower unit installation
The humiFog Direct system works by connecting the cabinet to a
number of blower units installed directly in the room to be humidied
and/or cooled.
The following simple rules must be kept in mind when installing the
blower units:
• the minimum ow-rate that can be atomised in the room is 8 l/h
(irrespective of the size of the pump). The minimum number of blower
units must therefore be dened based on the number and size of the
chosen nozzles.
The maximum numbers of blower units that can be connected to a
cabinet are:
• 12 blower units with 2 nozzles
• 6 blower units with 4 nozzles
• 3 blower units with 8 nozzles
The blower units must be suitably positioned so as to allow complete
absorption of the sprayed water. Consequently it is recommended to
install the blowers a due distance apart, at a sucient height from the
oor and with free space at the front without obstacles.
Do not install the head units in recesses, closed corridors or behind curtains,
as this would hinder the uniform diusion of humidied air. At the fan heads
the air is cooler and more humid and the noise emission of nozzles and fans
must be taken into consideration. Position the heads so as not to cause
discomfort to the occupants of the room. Do not install in areas where the air
is contaminated, particularly by microorganisms or allergens.
The blower units can be mounted either on the wall or on the ceiling.
For a correct installation, see the example or contact Carel for dierent
temperature and humidity conditions.

The blower unit installation procedure is as follows:
1. Unpack the blower unit from the box it was delivered in. The blower
units are delivered fully assembled.
2. Remove the side plastic covers cover from the blower. Unscrew the
long screws on the side using a screwdriver. Make sure to keep the
screws, as they will be needed again for assembly at the end.
3. Mount the blower unit on the metal support. See paragraph
"Mounting single blower units on the wall / ceiling".
4. Connect the water line to the inlet on the blower units (M16x1.5).
See paragraph "Mounting single blower units on the wall / ceiling".
5. Electrically connect the blower units to the cabinet, which supplies
power and controls operation of the fans. See paragraph "Blower unit
electrical connection".
6. Complete blower assembly by repositioning the side plastic covers
removed previously, and xing them with the same screws as
removed at the beginning.
5.2 Mounting single blower units on the
wall / ceiling
The single blower units (P/N DLA%F) are designed to be installed on a
vertical wall using a special metal support to be xed to the wall using
screws. Check that the wall is made from suitable material and is able to
support the weight of the blower unit (concrete, not plasterboard).
Fig. 5.b
First remove the blower unit from the packaging and take o the side
plastic covers. Remove the blower unit from the steel bracket on the rear.
Rest the bracket against the wall in the position where the blower will be
installed, and then drill four holes in the wall, using the steel bracket as
the drilling template.
Fig. 5.c
Fig. 5.d
After having drilled the holes in the wall, x the metal support using
anchor screws (not supplied).
Then attach the blower to the protrusions on the wall-mounting support
bracket.
Fix the blower unit to the bracket using the screws supplied in a bag
inside the packaging.
Fig. 5.e
When tightening the rst screw (M6 self-tapping in Ø=5.5 mm holes),
slightly loosen the screws on the ring clamps that support the nozzle
manifold, so as to be able to turn it and free up space to continue
mounting the unit. Tighten one screw on the right and one screw on
the left.
Then tighten the third screw (M4 self-tapping in Ø=3.5 mm hole) on
the right-hand side of the blower (opposite the terminal block). When
tightening this screw, the angle of the blower can be adjusted between
-10°/-5°/0°/+5°/+10° from horizontal, using one of the ve small holes
provided.
Then make the water connections, connecting the feedwater line
either on the right or left of the blower, and the water return line on the
opposite side.
Fig. 5.f
Finally, t the two cable glands and complete the electrical wiring, as
described in paragraph "Blower unit electrical connection".
Carel also provides an additional kit (including a special plate bent at 90°)
for mounting single blower units on the ceiling.
Fig. 5.g
5.3 Mounting double blower units on the
ceiling
The double blower units (P/N DLA%B) are designed to be installed on
the ceiling by anchoring them to a metal support that can support their
weight and the vibrations due to the pressurised water. To mount the
blower unit, use the special attachments provided on the unit’s metal
structure.
Carel provides additional kits with everything needed to complete
installation easily. Make sure to carefully choose the point where the
vertical support bar will be anchored. The support bar must not be longer
than 1 metre, so as to avoid excessive bending and vibrations.

ENG
"humiFog direct" +0300073EN rel. 1.4 - 29.03.2022
Fig. 5.h
After installing the blower, make the water connections by connecting
the feedwater and return lines to the two pipes provided on the top of
the blower. The feedwater/return lines can be connected either to the
right or left.
Fig. 5.i
Finally, t the two cable glands and complete the electrical wiring, as
described in paragraph "Blower unit electrical connection".
5.4 Blower unit electrical connection
The blower units must be electrically connected to the cabinet so that
they are activated only when there is a humidication request. The
necessary cable ttings are included in the delivery.
Before electrically connecting the blower units to the cabinet, make sure
that the cable glands supplied with the cabinet and the blower units are
available. All connections to be made by the user (cabinet power supply,
blower unit power supply, probe connections, etc.) must be performed
by running the cables through the cable glands, and in accordance with
local safety standards.
Also check that the cable is the right size for the distance and voltages
used. Carel recommends an AWG14 or AWG12 cable, as shown in the
technical data at the end of the manual.
To connect power to the blower units, connect three suitably-sized wires
(line + neutral + earth) from the terminals on the cabinet (shown in the
gure) to the terminals on the blower (shown in the gure). To power
a second and subsequent blowers, start from the free terminals on of
the previous blower and connect to the terminals on the next blower, as
shown in the gure.
Fig. 5.j
Important:
• remember to run the wires through the cable glands (marked in the gure).
• check the maximum number of blower units that can be connected to each cabinet in the tables in Appendix 12 at the end of the manual.
• when connecting the line (L) and neutral (N) from the cabinet to the blower units, never reverse L and N. Reversing or crossing over the wiring may cause
short-circuits.
After having completed the wiring, close the side plastic covers again and x them using the screws. The system is now ready to operate.

6. ELECTRONIC CONTROLLER SET UP AND CONNECTIONS
After having correctly installed the cabinet and completed the water and
electrical connections, connect the signals used to interface with the
humiFog Direct humidier to the c.pHC electronic controller (and the
c.pCO controller on two-zone cabinets.
Fig. 6.a
6.1 Remote ON/OFF signal connection
The remote ON/OFF contact is used to enable operation from an external
device. It is a digital contact that can be either open or closed: when the
terminal is open, humiFog cannot operate. The contact refers to inputs 7
[GND]- 8 [digit] on terminal M2 on the c.pHC.
The remote ON/OFF contact must not be confused with the ON/OFF
signal that manages operation, described in paragraph "Digital signal
from humidistat or external controller".

If not intending to use an external contact to start / stop the unit, leave
the terminal short-circuited (as supplied).
6.2 Analogue signal from the main probe
and limit probe in the rst zone
humiFog Direct can be controlled using an analogue signal (modulating)
from a main humidity or temperature probe connected to the c.pHC
electronic controller. If connected to a humidity probe, humiFog Direct
will display the relative humidity read by the probe. If connected to a
temperature probe, on the other hand, humiFog Direct will display the
temperature. Based on the probe reading and the deviation from the set
point, humiFog Direct will modulate the humidication load according
to the PWM principle (see paragraph "Control"). The following types of
probes are allowed:
• 4-20 mA, 0-20 mA current probes
• 0-10 V, 0-1 V, 2-10 V voltage probes
The analogue signal from the main probe in the rst zone is connected to
the c.pHC controller via inputs 1 [IN a] 2 [GND] 3 [+12 Vdc] on terminal M2.
The limit probe (optional) is used for the auxiliary function to reduce
humiFog Direct humidication or cooling capacity when approaching
a set humidity or temperature threshold (on the display or external
controller). To set the threshold, select operation with limit probe on the
display. The threshold will either be a humidity or temperature value. The
limit probe can also be used without using a main probe.
The following types of probes are allowed:
• 4-20 mA, 0-20 mA current probes
• 0-10 V, 0-1 V, 2-10 V voltage probes
The analogue signal from the limit probe in the rst zone is connected to
the c.pHC controller via inputs 5 [IN a] 6 [GND] 3 [+12 Vdc] on terminal M2.

c.pHC, the third wire must not be connected to input 3 [+12 Vdc] but
rather to terminal GA1 [+24 Vac], made available on the cabinet terminal
block, right above the c.pHC.
6.3 Analogue signal from the main probe
and limit probe in the second zone
If a second zone is used (only with UA%DD201 and UA%DU201 cabinets),
the main probe corresponding to the second zone must be connected to
the c.pCOe expansion installed under the c.pHC controller.
The following types of probes are allowed:
• 4-20 mA, 0-20 mA current probes
• 0-10 V, 0-1 V, 2-10 V voltage probes
The inputs used for the main probe are U1 [IN a] and [GND] on terminal
J2, and the power supply is taken from the +Vdc on terminal J9. The limit
probe (optional) corresponding to the second zone is connected to
inputs U2 [IN a] and [GND] on terminal J2, and the power supply is taken
from the +Vdc on terminal J9.

"humiFog direct" +0300073EN rel. 1.4 - 29.03.2022
6.4 Analogue signal from an ext. controller
As an alternative to the main probe, a signal from an external controller
can be used. The latter processes the request to send to humiFog Direct
via an analogue signal, which varies from 0 to 100%. humiFog will adjust
the capacity delivered proportionally to the signal received, and the
display will show the request sent as a percentage.
The following types of proportional signals are allowed:
• 4-20 mA, 0-20 mA current signals
• 0-10 V, 0-1 V, 2-10 V voltage signals
The external signal for the rst zone is connected to the c.pHC controller
via inputs 1 [IN a] and 2 [GND] on terminal M2.
The external signal for the second zone is connected to the c.pCOe
controller via inputs U1 [IN a] and [GND] on the terminal J2.

second zone to the c.pCOe expansion card: U2 and GND of connector J2
and voltage supply to Vdc terminal of connector J9.
6.5 Digital signal from humidistat or
external controller
The signal from the external controller can be replaced by the signal from
a humidistat, thermostat, or any external device with digital contact. In
this case, humiFog Direct will work in ON/OFF mode, either delivering
100% of ow-rate or remaining in standby. The capacity delivered can
be reduced by setting parameter P0 (the reduction is managed by PWM,
see paragraph "Settings"). The electrical connection is the same as in
the previous case (see gure in para. "Analogue signal from external
controller"). WARNING: congure the setting of humiFog Direct (via
display screens), so that it can be controlled by an ON/OFF signal from an
external controller or device.
6.6 Serial or Ethernet communication
humiFog Direct can be controlled by a supervisor that reads the humiFog
Direct parameters and sends commands. To connect a supervisor, the
RS485 serial port (terminal M12, inputs 1 [Tx/Rx-] 2 [Tx/Rx+] 3 [GND]) or
Ethernet port is used. The choice of which port to use depends on the
supervisor. Modbus and BACnet communication protocols are available

"Connectivity"), so as to monitor and control humiFog Direct via a local
network, without needing a supervisor.
6.7 Alarm relay output
The digital output for communication of an alarm status is connected to
contacts 1-2-3 on terminal M6 on the c.pHC. N.C. logic is set by connecting
the two wires to contacts 1-2, while N.O. logic is set connecting the two
wires to contacts 1-3.

6.8 Unit status digital output
The c.pHC controller provides a digital output corresponding to unit status.
This is a voltage-free contact that provides the following information:
• contact closed: unit on or in standby
• contact open: unit o (OFF from keypad or from remote contact, or
no power)
The unit status digital output is available at contacts 1-2 on terminal M5
on the c.pHC.
6.9 Production percentage analogue
outputs
The c.pHC controller provides an analogue output (0-10 V) corresponding
to the percentage of production that humiFog Direct is delivering.
The output replicates the request signal relating to the corresponding
humiFog Direct zone.
The production percentage analogue outputs are connected to the
following terminals:
• zone 1: outputs 1 and 2 on terminal M8 on the c.pHC.
• zone 2: outputs U3 and GND on terminal J2 on the c.pCOe.

unit parameters. There are at most 10 steps to set up the unit:
Step 1/10
Enter the humidier model.
Step 2/10
Enter the humidication load in kg/h for zone 1 and, if present, zone
2. The humidication load can be easily calculated by multiplying the
number of atomising nozzles in the zone by the ow-rate delivered by
each nozzle.
Step 3/10
Select zone 1 control mode from the options:
• ON/OFF contact (e.g. humidistat);
• External signal:
• External signal + humidity limit probe;
• External signal + temperature limit probe;
• Main humidity probe;
• Main temperature probe;
• Main humidity probe + humidity limit probe;
• Main temperature probe + temperature limit probe;
• Main humidity probe + temperature limit probe;
• Main temperature probe + humidity limit probe;
• Two main humidity probes (weighted average);
• Two main temperature probes (weighted average);
If using wireless probes, select the parameter that is shown by default
and at the end of the wizard refer to chapter “9. WIRELESS PROBES;
INSTALLATION AND CONFIGURATION”.
Step 4/10
Select zone 2 control mode. The options available are those already listed
in step 3/10.
Step 5/10
Select the type of signal from the main probe or from an external
controller to control zone 1:
