User Manual HomeVision®
Intended use
HomeVision® is developed and intended for wireless control and supervision of Corroventa CTR STD-
TT and CTR 300TT2 crawl space dehumidifiers and it consists of aControl Unit and a Control Panel.
Through use of the Control Panel mounted in the in the aparent the system can be monitored and its
settings adjusted. The climate can be controlled traditionally with a set point relative humidity as
well as through the use of Mould Growth Index which under certain circumstances has the potential
to further decrease the energy consumption.
For easy follow-up, the Control Panel provides a graphic presentation of operational hours, average
temperature and relative humidity. Any detected disturbance to the operation is automatically
presented as an alarm and so is the service reminder. The Control Panel also stores operational data
on a USB memory stick readable with Excel or other similar software.
A Control Panel can connect up to eight Control Units so even if the building requires more than one
dehumidifier, all control and monitoring can be done from one and the same position provided of
course the Control Units are all within radio coverage.
•Control and supervision of crawl space
climate, temperature and relative humidity
•Logging of operation and climate data on USB-
stick – available for users of the Pro version
•Operation indicators and alarms
•Easy to install – wireless Control Panel
•Service reminders
•Graphical display with an easy interface

Safety Information
This equipment is not intended to be used by individuals with physical or mental disabilities impeding
their operation or understanding of it or by individuals lacking required knowledge or experience
unless they are supervised and instructed by another person with responsibility for their safety.
Children must only use this equipment under supervision of an adult to ensure that it is not used as a
toy, something that it is not designed for.
Electrical installations made in connection with the installation of the dehumidifier or the
HomeVision® shall be made by authorized personnel in accordance with local and national
regulations.
1. Read and observe the Safety Information in the user manual of the dehumidifer that is to be
installed and/or used.
2. Incorrect settings in HomeVision® can result in damage to property and/or the equipment as
well as too high energy consumption.
3. The Control Unit is connected to the dehumidifier with its cable and is mounted in the crawls
space at approximately half the height in such a way that it is not affected by:
a. The dry air from the dehumidifier.
b. The wet air from the dehumidifier.
c. Radiation from surfaces warmer than ambient air.
d. Radiation from surfaces colder than ambient air.
4. Place and mount the Control Panel:
a. In hallway or similar space where it is often passed and seen so that any appearing
alarm is spotted shortly.
b. Beyond the reach of small children in order to avoid unintentional changes to system
settings.
5. As the Control Panel is intended to be continuously powered through included AC/DC
adapter, do not leave batteries in the Control Panel as many makes and types have a
tendency to leak as they age.
6. To use electrical equipment i a very humid or wet environment can be dangerous. Do not use
or operate the dehumidifier if it, or its Control Unit are in water.
7. Water must not come in contact with or reach the electrical components of the dehumidifier
or the HomeVision®. If this still happens, make sure they are dry before the system is
powered and used again.
8. It is recommended that the power socket used to supply the dehumidifier is protected
through a residual current device / ground fault circuit interrupter.
9. Be careful not to damage the cables. They must not be submerged in water or pass sharp
edges.
10. HomeVision® must not be used with any other accessories than those presented in this
manual or that are explicitly approved by Corroventa Avfuktning AB.

Relative humidity and its effect on substances
All air contains more or less moisture but the naked eye cannot see it until it condensates in small
droplets on for instance a metal or glass surface. Already before it is visible however, the moisture
affects substances and production processes, causes corrosion and micro organism growth. In the
Nordic climate in particular, one must always count on ambient humidity due to the large water
surfaces of the many thousands of lakes and of the surrounding sea.
Air humidity is measured and referred to in terms of relative humidity (%RH) which is a measure how
much water it contains relative how much it can contain at given temperature. The higher the
temperature, the more water the air can contain but it is still the Relative Humidity that counts and
that needs to be controlled.
At RH 100% the air is saturated – there is fog and the moisture condensates in small droplets.
Already at RH 60% steel corrodes and at 70% there is a risk for mould growth. As a rule of thumb, RH
50% is a good climate for most substances but in the Nordic countries the humidity is rarely that low.
The yearly average for most places is closer to 80% and it can be as high both summer and winter.
Control of crawl space humidity
When a dehumidifier is installed in the crawl space in accordance with instructions in manual, vents,
cracks and other openings are sealed and the ground is covered with non-aging plastic foil, all
prerequisites are there for achieving and sustaining a good climate where rot, mould and bad smell
are prevented. As an extra prevention, downpipes that end by the foundation wall should be
modified so that the water is lead away from the building and do not leak into the crawl space.
HomeVision® with its wireless Control Panel offers easy and convenient monitoring of the crawls
space environment and allows the user to set desired operating parameters for Fixed RH control and,
for Pro also Mould Growth Index RH control.
Fixed RH control
With RH control a setpoint is selected, a relative humidity one wants the system to use as basis for its
dehumidification. Furthermore, one defines an upper and a lower hysteresis as well as an alarm limit,
the latter defining an alarm level at which, should it ever be reached, an automatic alert is triggered
on the Control Panel. The diagram is not to scale but only intended as an illustration of the principle
presented and its different parameters.

To further facilitate the understanding of the principal, the example below presents all the
parameters and explains how they are applied.
As can be seen from the example above, the setpoint shall not be seen as, or confused with, a
maximum level as it is exceeded with Hysteresis Upper before the dehumidifier is even activated. At
times of high moisture load, the relative humidity can climb even further before it starts declining.
Consequently, the setpoint is, if not perfectly correct, more to be seen as an upper limit for the
average relative humidity and therefore there must always be a margin bigger than the Hysteresis
Upper between the setpoint and the level at which damage arises.
The reason for HomeVision® allowing the user to set the hysteresis is to allow for each and every
installation to be optimized. A too narrow span results in many starts and stops of the dehumidifier
with increased wear on the equipment. A too wide span normally results in the system drying the
crawls space to unnecessarily low levels which consumes more energy than necessary.
Setpoint, %RH: 65%
Activation: Setpoint+Hysteresis Upper = 65% + 4% = 69%
Deactivation: Setpoint +Hysteresis Lower = 65% - 4% = 61%
Hysteresis Upper/Lower: + 4%, -4%
Alarm, +%RH: 10% Added to the activation level to give the Alarm Level.
Alarm Level = Setpoint + Hysteresis Upper + Alarm =
65% + 4% + 10 % = 79%

Mould Growth Index RH control
In addition to Fixed RH control, HomeVision® Pro also implements Mould Growth Index, MGI,
control. The control mechanism makes use of the fact that mould growth, in addition to being
humidity dependant also is temperature dependant. At lower temperatures, higher humidity can be
tolerated without causing mould growth, the positive side of which is of course the potential to save
further energy.
The MGI control principle, as explained implemented in HomeVision® Pro for its energy saving
potential, is visualized in the schematic diagram below. The diagram is not to scale but intended only
to explain and clarify the principle and its parameters.
The upper curve, the Mould Growth Index curve, is programmed in HomeVision® Pro and is not
affected by user settings. The user is instead allowed to set RH safety margin, Hysteresis Upper and
Lower and alarm limit, the meanings of which are explained by the following example.
The principals are familiar to those acquainted the Fixed RH control but instead of a set point a safety
margin is defined. As with the Fixed set point, the RH safety margin is exceed by the Hysteresis Upper
before the dehumidifier is activated. The RH safety margin does thus not constitute a maximum
level. As for Hysteresis and the Alarm, these function the same way with MGI as with Fixed.
RH safety margin, %RH: -15% Activation:
Current MGI– RH safety margin + Hysteresis Upper =
= Current MGI – 15% + 4%
Hysteresis Upper/Lower: + 4%, -4% Deactivation:
Current MGI – RH safety margin – Hysteresis Lower =
= Current MGI– 15% - 4%
Alarm, +%RH: 10% Added to activation to level to give Alarm level.
Alarm level:
Current MGI – RH safety margin + Hysteresis Upper + Alarm=
= Current MGI – 15% + 4% + 10 %
Current MGI = The relative humidity that for current temperature is the lower limit for mould growth.

As the reader has understood already, it is in the lower temperature interval that the relative
humidity supported by Mould Growth Index can be allowed to rise somewhat higher and thus
achieve an energy saving. For higher temperatures, the two control modes coincide and the energy
consumption is thus identical.

Installation
Installation of Control Unit and connection of Control Panel
When installing the Control Unit, prepare the Control Panel by removing the battery protection and
bring it to the crawl space.
1. Mount the Control Unit where its cable can reach the dehumidifier and where its
measurements of temperature and relative humidity will be representative of the ambient
crawl space environment, securing that:
•The unit is at approaximately half the height of the crawl space.
•The unit is not directly affected by the dry air from the dehumidifier.
•The unit is not directly affected by the wet air from the dehumidifier.
•The unit is not affected by radiation from heat sources/surfaces hotter than ambient air.
•The unit is not affected by radiation from surfaces colder than ambient air.
The Control Unit is mounted in bracket, part of the installation kit (Monteringskit TT Multi)
with the sensor downwards. The bracket is preferably fixed as depicted below.

the Control Unit, the Control Panel
displays a warning about the temperary
nature of service pairing. If this screen is
presented and the selection of this type
of pairing was unintended, push Exit to
return to previous menu and restart the
process.
The Control Panel now searches for and
identifies Control Units available for
connection. Wait for this process to
finish which is to be expected within 30
to 40 seconds. If the process should take
considerably longer, restart the Control
Unit and try again.
When the process is finished, identified
Control Units are presented. If there are
several units on the list, select by

Installation of Control Panel
When the Control Unit is installed and radio connection between that and the Control Panel is
established, proceed as follows:
1. Select position for the Control Panel where there is power outlet within reach of the power
adaptor cable and preferably where any alarm would be noticed as soon as possible (the
screen back light starts to flash when alarms are presented). Furthermore, if there are small
children in the household, the Control Panel should be placed beyond their reach.
Put the Control Panel at the intended position and leave it there for a couple of minutes to
let the signal quality indication reflect current conditions. Verify that at the indication is at
level two or higher.
2. Detach the wall bracket from the Control Panel by pushing it downwards. Hold the bracket to
the wall at the intended position and mark the position of the three holes to be drilled. Drill
the holes and insert the wall plugs. Fix the bracket to the wall using the three screws.
3. Remove the batteries from the Control Panel and connect the power adaptor. (The Control
Panel, if correctly paired, will automatically reconnect the Control Unit after power down.)
4. Mount the Control Panel on the wall bracket by holding it over the bracket and pulling it
downwards. Connect the power adaptor to the power outlet.

To use HomeVision® Pro
HomeVision® has an easily understood user interface with a display and three push buttons. The
push buttons are so called soft buttons meaning that their respective functions vary with the menus
to make the maneuvering as simple as possible.
The menus are all depicted below except for automatic alarms and reminder which are presented in
separate chapter. From the default view, the menus are reached through the center setup button.
The right Overview button presents current status data for all connected Control Units in a tabular
form to allow comparison. The left down arrow in the default view is used to present operation,
temperature and relative humidity statistics. In the statistics views, the first column from the right is
the current calendar month, followed by the last completed calendar month and so forth.
When using and operating HomeVision®, remember the following:
•If no button is pushed, the Control Panel presentation automatically returns to the default
view after 30 seconds. The only exception to this is when a Diagnostic test is activated in
which case the presentation remains with this test until it is completed and only thereafter
returns to default.
•If no button is pushed, the display back light goes out, switches off, after 15 seconds. When
the back light is not lit, the first button push has no other function than turning on the back
light. This also applies if and when an alarm is active and the back light is flashing.
•The Control Unit connected to the dehumidifier is, for its own function and control of the
dehumidifier, independent of the Control Panel. Thus even if the radio communication with
the Control Panel should be interrupted, the Control Unit continues to operate and control
the dehumidifier according to its settings.

Default view
Default view
In the default view, current crawl space relative
humidity and temperature are presented.
The user can also read whether dehumidification is
currently ongoing and whether the fan is active or not.
The far right symbol with the bars presents radio
communication quality.
If more than one Control Unit is connected, the default
presentation steps between all of them in a continuous
loop where each unit is displayed for five seconds. The
A1 identity in the top center of the example to the
right indicates that the data currently displayed is that
of the first unit.
The indications in the lower part of the screen show,
from left:
•Dehumidification, if the dehumidifier is
currently active or not. When active, the water
level in the droplet is moving and the outer
circle rotating.
•Fan – if the fan is currently active or not. When
active the fan wheel and the outer circle are
both rotating.
•Signal quality, how good the connection with
the Control Unit is. The higher the indication,
the better quality. When connection is lost, the
entire symbol flashes.
Please note that the signal quality reflects how
many data packages are correctly received in
their first transmission. The level normally
builds up over time and may then vary slightly.
Standard paired systems automatically
reconnect after power reset. When the Control
Unit has been powered down it takes
approximately three minutes for the system to
reestablish communication.

Overview
The Overview, a function accessible with the left
button in the default view, presents current status
data of all connected Control Units in a tabular format
allowing comparison.
In addition to temperature and relative humidity, the
user can also see whether dehumidification is ongoing
and if the fan is active or not. The respective symbols
used are recognizable from the default view.
When more than three units are connected and thus
all units cannot be simultaneously displayed, the right
button has a down arrow symbol and allows for the
user to step down the list, machine by machine.
Setup
With center button <Setup> in the default view, all
setup and configuration available with the system are
accessed.

Connect new unit
For new installation or other situation where the
Control Panel does not already have a Control Unit
connected, please refer to chapter Installation of
Control Unit and connection of Control Panel.
If a new unit is to be connected as a replacement of
an old unit, make sure this old unit is deleted from
the system first so that its identity becomes available.
If not, the replacement unit will not get the same
identity as its predecessor which is unnecessarily
confusing to the user who might already have
memorized what identities corresponds to what
machines/positions in the building.
In default, status view push <Setup> to get to the
Administration view where the “Connect new unit”
function is found.
Push <Select> which makes the Control Panel highlight
the first row, Date/Time. Use down arrow, <▼>, to
step to “Connect new unit” and push <OK>.
For normal installation, select alternative ”Standard”
so that the units will reestablish communication
automatically, should there be for instance a power
cut.

After selection of connection type, for the Standard
alternative, the system will display a reminder of the
fact that the Control Unit is open to connection for
only two minutes after power-up. If Service connection
was selected, the system displays a warning informing
that this type of connection is not permanent. Push
<Continue>.
The Control Panel searches for, and identifies,
available Control Units. Wait for this process to finish
which it normally does within 30 to 40 seconds. If not,
restart the Control Unit and try again.
When the search is finished, the Control Panel displays
a list of the units found. Units that are already
connected to the Control Panel are not found in the
list, even if they were restarted. Also, normally, there
is only one unit in the list but if multiple Control Units
within radio coverage was recently restarted there can
be several units. Choose correct unit, if necessary by
comparing listed identities with the identity found on
the backside of the Control Unit, and push <OK>.
When unit for connection is selected, the system tries
to execute this order by exchanging required
information. Wait for this process to finish, at what
time the Control Panel displays applicable result as
depicted at the bottom of the illustration to the right.
If the connection was successful, the new Control Unit
is given an identity consisting of capital letter A
followed by the lowest available number in the interval
1 through 8.
