1 GENERAL INFORMATION
1.1 What can be expected from the work of an EBCeasy, what can't
1.1.1 Primary purpose
The miniClima Constant Humidity Devices EBC are built for the regulation of the relative air-humidity in both
air- and steam-tight enclosed museum showcases, switchboards, deposit cupboards, containers and similar
applications (hereinafter only referred to as "cases"). The devices help in reaching and keeping a desired
level of relative air-humidity inside the cases. They are not built for the purpose of influencing or changing
any other state or condition of the air being processed (e.g. temperature, pollution, etc.), but further
equipment1 can be added to an EBC for filtering dust and particles out of the system air.
1.1.2 Characteristic features
Once set up correctly, the EBC, the case and the interconnections between EBC and case (hosepipes)
together form a tight air circulation system. As long as the EBCeasy is turned on and has adjusted its internal
air-leading parts, the air circles almost continuously through it. More in detail: The air is exhausted from the
case, led to the EBC, where it is going to be either humidified, dehumidified or left unchanged - depending on
the set and actual RH values. The conditioned air is then led back into the case. Conditioning is achieved by
means of a solid state polymer ionic membrane. On one side of the membrane it splits hydrogen ions (H+)
from the air, migrates it through the membrane and discharges it on the other side. The membrane can only
be used in one direction. Therefore the EBCeasy is equipped with a mechanism to switch the air-stream
between both sides of the membrane depending on the necessity to humidify or dehumidify. The respective
other side of the membrane is opened to the surrounding air to equalize the generated humidity level.
When the EBCeasy has to change its operation-state between humidifying, dehumidifying or just circulating,
it first stops its circulation fan, then closes flaps being open to the outside and then opens flaps according the
new operating state and starts the circulation fan again. The outside air is therefore never opened to the
internal air-stream directly. Moreover to avoid the transport of external particles into the internal air-stream,
the outside air is filtered by filter-pads of filter-class F6 on the incoming side and of filter-class F3 on the
outgoing side.
During all these times a digital sensor measures the values for relative air humidity and temperature within
the case. The EBC receives these values and compares the measured RH value with the setpoint, the

hysteresis and the threshold values, which can all be set via the menu prompts on the front panel of the
EBC.
Through the work of the EBC, the desired level of the air humidity in the case is constantly approached -
duration and speed depending on the initial values, on the conditions (temperature, humidity) the case is
exposed to, and on a number of further variables (like the temperature at the EBC's place of installation, the
size and shape of the case, the air/steam tightness of the case, the kind of materials stored inside the case,
the length of the hosepipes, whether or not the hosepipes are laid in many bends and turns etc). After the
setpoint range (=setpoint +/- hysteresis) has been reached, the RH is going to be kept on a constant level. A
negligible movement around the setpoint might be observed. This behaviour is technically induced and does
not constitute an error.
A typical reaction process can be seen in the following picture, showing the humidification and
dehumidification by an EBCeasy1 for a showcase of 1,0m³ (RH: blue, T: red) at 30%RH, 22°C surrounding
conditions.

1.2 Risk of use, recommendations
Our devices are first and foremost used for the regulation of the relative humidity of the air surrounding
precious and/or irreplaceable works of art or artefacts. It is therefore necessary to cover all possible
imponderables, when installing and using the EBCs. For this purpose, please do bear in mind the following
recommendations and risks of use.
A clean installation, carried out according to the instructions found in this manual, is the basis for a working
system. In particular essential are:
The use of a climate-ready case (air-tight, steam-tight).
The positioning of the miniClima RH/T sensor on a spot that features the same environmental conditions
as the one where the exhibit is placed (see section 3.2.3 "RH/T sensor", p. 1 ).
The design and positions of the air inlets and outlets on the case (see section 3.1 "Setting up the EBC,
establishing the hosepipe connections", p. 10).
That the air resistance within the air circuit is kept low (short hosepipe connections, avoidance of too
many bends and turns when laying the hosepipes etc. - see section 3.1 "Setting up the EBC, establishing
the hosepipe connections", p. 10).
Preventing different temperatures inside the case (light installations, solar radiation,...). The miniClima
RH/T sensor and the exhibit in particular need to be exposed to the very same temperature.
The temperature surrounding the EBC and the hosepipes (see section 3.1 "Setting up the EBC,

establishing the hosepipe connections", p. 10).
Regular visual inspection of the EBCs, regular maintenance and care of the EBCs (see section 7
"Maintenance and care", p. 38).
We recommend a beforehand verification by the user/customer that our product is going to be able to fulfil
the individual expectations and needs required for the specific case. Please don't hesitate to get in touch for
any questions.
It is further recommended to test the function of a completely installed system (consisting of the case, the
interconnections and the EBC(s)) before using it to control the relative air-humidity of sensitive exhibits or
components. In doing so, possible errors (i.e. wrong installations) can be discovered early enough to have
them corrected.
Please bear in mind that every technical device can break. So, to be on the safe side with respect to the
lasting integrity of your sensitive and valuable exhibits or components, further actions should be considered:
Regular inspections of the case and the EBC through skilled personnel probably provide for the highest
possible safety against technical failures or breakdowns.
Installation of external signal devices for every EBC, to be alarmed in time when one of our devices
needs attention (see section 3.2.5 "Wirings for the external signals (Composite error alarm and on-off
status)" on p. 16).
Having a spare unit at hand if need be or when the regular inspection at our workshop becomes due. You
can save time and avoid delays during which your case might remain without humidity control. Those who
decide for this option should actually best have their EBCs rotate in regular intervals.
Please mind to install, use, maintain, deinstall, pack up, store and ship your EBC and all accessories
correctly and in accordance to the instructions.
1.3 ermissible ambient conditions
-5 - 30°C, 15-80%RH, non-condensing (applies to the storage of the EBC as well as to the operation of
the completely installed system as a whole).
Note: The performance ot the EBCeasy also depends on the humidity of its environment, as a high
difference of the humidity inside and outside of the showcase can cause diffusion of humidity through the

membrane.
NOTE: The values -5 - 30°C and 15-80%RH refer to the air-conditions surrounding the EBC and the case
which are generally obligatory for operation (or damage-free storage) of the EBC. They do not refer to the
surrounding air-conditions were the full capacity with respect to the achievable setpoint range (inside the
case) will be given (see also section 9 "Technical data", p. 0).
1.4 Further requirements for using EBCs
The EBCeasy has to be operated with 12V DC, 2 W. An according wall power supply is usually part of
delivery.
1.5 Available types
EBCeasy-1 device for air volumes of up to approx. 1,0m3.
EBCeasy-2 device for air volumes of up to approx. 2,0m3.
NOTE: The capacity of an EBC will differ depending on the ambient conditions, the tightness and
constitution of the case, the tightness and constitution of the connections between case and device, the kind
and consistency of the materials stored/presented inside the case, and the like.
Every EBC of the current series can be used as both a master unit and a slave. The decision for one of the
two hierarchic states is selected automatically dependant upon the type of cable connected to the EBC. If it
is the cable of a miniClima RH/T sensor then the EBC becomes a master controller; if it is the control line
coming from another EBC then the unit becomes a slave and will duplicate the function of the EBC that is the
first in the line (chain of EBCs).
With this it is possible to increase the max. volume of the air that can be conditioned: Every added
EBCeasy1/2 increases the capacity by approx. 1,0/2,0m3.

3 INSTALLATION
3.1 Setting up the EBC, establishing the hosepipe connections
NOTE: If you have ordered air-distribution-boxes (LVB20), filter boxes, or other accessories relevant for
the hosepipe connections, do also regard their additional installation manuals at this point.
The EBC should be positioned as close as possible to the case, to keep the air resistance, which increases
with the length of the used hosepipes, low. The EBC should not be located in the air-conditioned part of the
case itself. The device has to be installed horizontally and firm. The device has to be given the possibility to
emit its self-produced heat during the operation. It is therefore necessary to ensure, that…
1) ...the device's place of installation (mostly the plinth of the case) is aired (e.g. by means of ventilation
holes in the plinth , or by ventilation fans, if necessary);
2) ...the EBC is placed on a plain surface
3) ... the filter grills on the sides are not blocked and that edge distances of min. 10mm (right side, left side)
are kept for an adequate ventilation;
) ...the air slits are vacuum cleaned regularly, if necessary, and the filter(s) behind the air grill(s) on the right
Recommended sizes and positions for the ventilation holes: 2x50cm2 per EBCeasy: top & bottom panel of the plinth and/or both side panels of it.

and/or left side are regularly checked and replaced (see section 7 "Maintenance and care", p. 38).
 CAUTION: Absence of ventilation at the device's place of installation or blocked cooling air in-/outlets of
the device might overheat the device, as well as reduce the dehumidification and humidification capacity of
the device.
Note: The performance ot the EBCeasy also depends on the humidity of its environment, as a high
difference of the humidity inside and outside of the showcase can cause diffusion of humidity through the
membrane.
Two hosepipe connections for the air circulation have to be established between each EBC and the case.
Follow the steps described below for each device that shall be connected to the case (includ. every slave
unit, if any):
The device itself is already equipped with two hosepipe fittings. The hosepipe fittings on the case wall need
to be affixed now. You need two hosepipe fittings for every EBC - one for the air inlet, one for the air outlet.
Firstly define the ideal positions of the air in-/outlets on the case so as to best enable an equal distribution of
the conditioned air.
NOTE: The positions shown in Fig. 6 do not represent a general solution or recommendation.
Mind the following rules before deciding:
1) As already mentioned above, all used EBCs should be positioned as close as possible to their respective
cases, though they can also be placed some meters away, if necessary. Due to the growing air resistance
the efficiency of the EBCs diminishes a little with the length of the tubes. Mind the total length of the
hosepipe provided with your EBC.
2) The hoses must not be laid next to heat-emitting parts.
3) In- and outlets (even those of different EBCs) must not be located directly next to each other on the case
wall (you may position inlets next to inlets and outlets next to outlets). If they need to be positioned close
to each other, anyway, the inner construction of the case should be realised along the ideas presented in
Fig. 6.
) The constructions on the inside of the case should be realised in a way that enables the air to stream
over the whole volume of the case. Should i.e. some air in- and outlets be located behind the same
partition wall or divider, the inlets need to be sealed off from the outlets even if much space is left
between those in- and outlets - see Fig. 6.

5) For partition walls / dividers / sealed off separations between in- and outlets: The overall surface of the
openings between each partition / separated part and the rest of the case should at least be of the same
size as the sum of the cross-sections of all hosepipes connected to this partition / separated part, thus
ensuring that the air does not need to overcome a higher air resistance there than it does inside the
hosepipes.
6) There is no universally valid figure for the permissible max. total length of the hosepipe connections per
air circuit between EBC and case but the length that is usually delivered with a device (3m) can be taken
as a reference.
Fig. 6 - The shown positions of the hose fittings do not represent a general solution or
recommendation.
As soon as the positions are fixed, you need to clarify whether the thickness of the case walls exceeds 6mm
on those positions where you want to bring on the hosepipe fittings. If the thickness is 6mm or less you may
cut, drill, or crack the holes for the hosepipe fittings directly in the case wall5: EBCeasy: Ø 20mm. If the
thickness is above 6mm on the other hand, you need to use intermediate pieces (not part of the delivery by
default) whose thicknesses actually are max. 6mm, e.g. metal plates like our flanges. The necessary
diameters for the boreholes when using flanges or the like result from the size of the counter nut and gasket
of the respective hosepipe fitting: VE20.. (EBCeasy): Ø 30mm;
 IM ORTANT: Mind the necessity that every air in-/outlet on the case has to be carried out airtight.
Hosepipe fittings, which are fitted directly to the case wall with the delivered gasket, need no further sealing.
3.1.1 Handling the hosepipe fittings
3.1.1.1 Handling VE20_V3
1) Cut the hosepipe as straight and even as possible. We recommend the use of nippers built for that
purpose (can be ordered with us).
2) The connectors have to be affixed to either the showcase wall or to an intermediate piece/flange using
5Mind that purpose-made models might be equipped differently. Always measure off the delivered parts before cutting/drilling/cracking. Also, EBCs that shall be used together
with LVBs will need different boreholes on the case walls - see the delivered installation manual for the LVBs.

3.1.2 Connecting the hosepipes to the EBC
Dispose of the protective coverings on the hosepipe fittings of the EBC, if any. After that, proceed as
described above in order to attach the hosepipes to the EBC's fittings. Mind the different types of fittings
mentioned above.

3.2.1 Plugging and securing the 12V Connection
The cable of the 12V power supply shall be laid betweenthe handle and the housing to achieve a kind of
strain relief.
3.2.2 Handling the ferrite core
In case you need to take off the ferrite core(s) of the RH/T sensor cable or the control line temporarily, this
can be done easily (kind and colours of the cores vary):
 IM ORTANT: Do not forget to put the core(s) back on the cable before using the EBC: Wind the cable
through each core once - see the pictures above. The core(s) should be positioned next to the RJ 5 plug of
the sensor cable or next to each of the RJ 5 plugs of the control line respectively.
3.2.3 RH/T sensor
(Applies to EBCs used as master units only.)
Please see the printed note that has been added your delivery before handling the sensor.

necessarily have to be placed in the visible part of the case, but even so, it has to be positioned on a spot
and under conditions that are comparable to those of the exhibit in the case. Especially lighting installations
and their effect on the temperature of the air surrounding the sensor may have a heavy impact on the
functioning of a correct humidity control. Do not cover, wrap, or in any other fashion separate the sensor from
the air that surrounds the exhibit.
By default the sensor comes complete with housing, a 2.5m or 5m cable, a RJ 5 plug and a ferrite core. As
neither all parts of the sensor housing nor the plug can be detached from the cable, you need a borehole of
min. Ø 13mm in the case wall so as to be able to lead the complete sensor with housing and cable (sensor
sided) through. It is also possible to just plug the top of the sensor including its housing into the showcase, a
borehole of Ø 10mm is then enough.  IM ORTANT: The chip of sensor is an easily damageable electronic
component. Therefore it is important to take good care to not harm it when leading it through the wall! It is
also essential to take care for an airtight lead-through of the sensor cable through the wall of the case.
Once the sensor is positioned and mounted inside the case, verify that the EBC is still not plugged to the
mains connection. Then plug the sensor cable to its jack on the front plate of your EBC, labelled Sensor &
Control in. With the sensor plugged in, the EBC is already defined to be a master unit.
 IM ORTANT: Do not plug or unplug the sensor to/from the EBC during operation! Always turn the EBC off,
wait for the completion of the pumping process (if any) and then pull the mains connection before handling
the sensor cable. Otherwise the electronics of the EBC might be harmed and/or unexpected malfunctions
might occur.
3.2. Control lines
(Applies to master/slave-systems only.)
 IM ORTANT: Do not plug or unplug the control line to/from any affected EBC master or slave set as long
as they are operating! Always turn the master off (all slaves follow automatically) and pull the mains
connection cables of the affected EBCs before handling the control line(s) interconnecting the EBCs.
Otherwise the electronics of the EBCs might be harmed and/or unexpected malfunctions might occur.
Every EBC that is ordered as a slave unit is going to be delivered with a 2m or 5m control line - a customary
category-5e patch cable, twisted pair/non-crossed, with RJ 5 plugs and ferrite cores on either end. Verify all
EBCs are still not plugged to the mains connection, then plug one RJ 5 to the master unit's jack labelled

3.2.5 Wirings for the external signals (Composite error alarm and on-off status)
Every miniClima Constant Humidity Device is equipped with two potential-free changeover contacts that can
be used for the installation of external signals, i.e. red/green lights in a control room, or sirens. One signal
indicates whether the EBC is turned on or off, the other switches whenever the EBC issues an alarm.
 CAUTION: Max. voltage/amperage for using of the changeover contacts: 8V/ A.
The wires that shall be connected to the changeover contacts of the EBC have to be put to the EBC's 6pin
plug-in connector. Proceed as follows for handling the plug-in connector:
1) Grip the plug-in connector on its sides with index and thumb and pull it off from its connection plug. Hold
the EBC with your free hand when doing so, to keep it from being torn away ( IM ORTANT: The
connector has to be pulled off the EBC for all works that shall be done on it):
2) For removing or adding wires to the 6pin plug-in connector, press a small screwdriver into the hole to
open the according clamp beneath and pull/push the wire out/in at the same time:
3) It is best to accomplish all wished cable connections at once. For putting the plug-in connector back on
the device it has to be pressed onto the connection plug. Do hold the EBC with your free hand when
doing so, to keep it from slipping away.
Clamp positions: The live wire for each external signal has to be plugged to the resp. leftmost clamp, which

4.1 mains connection
Use the delivered wall power supply. At first plug the cable to the socket-inlet (backside) of the device. Then
plug the power supply to an appropriate (see section 1. "Further requirements", p. 8) socket-outlet. If
necessary, you can use any common and approved international mains plug adapter - still, voltage and
frequency of the mains connection have to be within the above (p. 8) mentioned range, and the connection
has to be fuse protected and earthed.
NOTE: In case of a power outage (or when the mains connection has been cut in any other way), the EBC
will always return to the last mode it had been working in (Stand-by or humidity control) as soon as the power
supply becomes reestablished. Also, all settings that had been taken on the EBC will remain intact despite of
any power outage.
4.2 Stand-by mode
Once a working mains connection has been established the EBC's LED lights up green and the display
indicates the software version programmed into the EBC's processor. After some seconds the display
switches to (“ser_no” corresponds to the respective serial number):
S t a n d B y s e r _ n o
Fig. 8 - Display message during stand-by mode (Master sets).
èS t a n d B y s e r _ n o
Fig. 9 - Same message on a slave unit. Slave mode requires an established connection to the master and
both the slave and the master have to be plugged to the mains supply.
The EBC adjusts its internal flaps to control the internal air-stream, the according engine noise can
be heard for some seconds. While in stand-by mode, an EBC will neither circulate the air between case
and EBC, nor will it start/continue with any humidifying or dehumidifying processes. Also no data will be
logged or provided live on the RS232 interface at this stage. Previously recorded data can be read out during
stand-by, though, and the menu on the EBC's front panel is accessible, too (see section . "Settings and
read-outs - working with the menu", p. 20).

4.4 Settings and read-outs - working with the menu
NOTE: The menu can be used both during operation and while the EBC is in stand-by mode.
The following variables can be set with the menu on the EBC front panel:
The setpoint for the desired level of the relative humidity inside the case (%RH) - Menu entry 1.
The upper and lower thresholds for the humidity alarm (%RH) - Menu entries 2 & 3.
The acoustic alarm (On/Off) - Menu entry .
The delay for the first humidity alarm (Days) - Menu entry 5.
The menu and display language (English/German) - Menu entry 6.
The correction for the interpretation of the data coming from the RH/T sensor (Calibration; %RH) - Menu
entry 11.
The hysteresis - Menu entry 12
Furthermore the following data can be read out from within the menu:
The temperature inside the case as read from the RH/T sensor (°C) - Menu entry 7.
The temperature at the membrane inside the EBC (°C) - Menu entry 8.
The temperature at the electric circuits inside the EBC (°C) - Menu entry 9.
The hours of operation of the EBC (Hrs) - Menu entry 10.
 IM ORTANT: Note down the current hours of operation of your EBC for future reference (cp. section 7.3
"General service" on p. 38).
NOTE: The menu is identical at masters and slaves, but some settings can only be taken on masters. If
you i.e. try to alter the setpoint or one of the alarm thresholds within the menu of a slave unit, the software
will switch back to the value set in the master shortly after.
NOTE: Any EBC will cancel the menu mode after a few seconds of inactivity. All changes that have been
made and then confirmed with ↵ Enter will remain intact. All changes that have not been confirmed before
will be rejected.
