5. WALL-MOUNTING OF THE CONTROLLER
Figure 2. Installation of the controller
The controller must be mounted on an interior wall, preferably in a clean room where
the humidity level is not excessive. Do not mount the controller above a heating system
or the like. When installing, ensure that the display is located at eye level and that the
perforated plate (Fig. 1, item G) is facing downwards. Keep an area of up to 26 cm free
to the left of the controller to ensure that the cover can be opened (see Fig.2).
Open the cover of the controller by removing the screw from the upper cover (see
Fig. 1, item D). Remove the cover from the connection compartment (Fig. 1, item J)
by removing the two retaining screws. There are 4 mounting holes: 2 in the top corners
of the housing, and 2 at the bottom (Fig. 1, item F). M4 or M5 screws can be used for
these holes. You will nd the hole pattern in the diagram below:

230V connection
Connect the incoming mains voltage to terminals L and N. When the main switch is set
to ‘On’, L will be connected through to L’.
It is then possible to connect, a humidier to L’, for example.
Optimization of energy and water consumption.
A humidier also uses energy (10 Watt) and water (rinse program) in the stand-by posi-
tion (230V switched on, no humidity generation).
You can reduce this by switching off the humidication completely if the RH is 10%
higher than desired. The dehumidication relay is used for the connection. The
dehumidication bandwidth must thereby be set to 10%. Up to and including the HU-85,
the humidier can be connected directly to the relay. If an HU-245 humidier is
installed, an auxiliary relay must be used. See the connection diagram on page 20.
7. OPERATION
Figure 5. Operation.
IMPORTANT
- Ensure that all the connections are soldered when lengthening a cable.
- In order to prevent interference, ensure that low-voltage cables (0-10V) are
never installed parallel to high-voltage lines (230V).
- Sensor wiring must cross electricity lines at a 90˚ angle.

Basic conguration for DZR-45
The DZR-45 has 3 different congurations, which can be selected via this menu.
Single hygrostat
Single hygrostat with 1 humidity sensor, 1 humidication output and
1 dehumidication output. For more data, see General Hygrostat Operation.
IMPORTANT
Some of the menus are hidden from the user if they have no inuence on the
operation of the controller.
For example: In a single hygrostat conguration, the menu for hygrostat 2 is
not visible.

Hygrostat with max.
This hygrostat operates in the same manner as the single hygrostat, but with an
additional sensor for maximum humidication. The additional sensor can be
placed in an air channel in order to limit the maximum humidity.
The sensor can be selected as follows:
Hygrostat -> maximum humidication -> sensor selection.
This will limit the humidication as soon as the measured relative humidity has
reached the set maximum value.
The set maximum value can be adjusted as follows:
Hygrostat -> maximum humidity -> humidity set point.
The setting for the bandwidth can be found under:
Hygrostat -> maximum humidity -> bandwidth.
Figuur 8. Hygrostat with maximun control.
Double hygrostat
In principle, this is the same as 2 single hygrostats. The regulation of
dehumidication is hereby not possible.
The output of hygrostat 2 uses the dehumidication output.
Two hygrostat submenus are available in the main menu.
In this way, 2 areas can be monitored with one controller.
Block mode
In block mode, the regulator is divided into several blocks with settings. Each
block can be activated based on time and/or an external signal. This makes it
possible for the conguration to operate during the day with a variety of settings.
It is also possible to indicate a uid type for each block. This feature allows the
regulator to supply R.O. water or another uid to the humidier.
For comprehensive information, please refer to chapter X Block conguration

Block conguration
The block conguration becomes active if Block mode is selected under DZR
Conguration. This conguration makes it possible to use time or another external
signal to operate the regulator in another manner. Firstly, the correct time needs to be
set. System -> Setting the time. The start screen will now be as follows:
All available blocks can be seen under Block settings. The rst block is the Standard
block. This features all settings that are active if none of the other blocks are active.
The other blocks (1 to 10) will only be active if the stipulated conditions have been met.
This could involve being within a certain time or could require a certain external control
signal to be present.
Block settings
Settings in the standard block mainly resemble those of the single hygrostat, but without
de-humidication. The Start time and Stop time setting is used to indicate the time within
which the block will be active. The Fluid type setting can, as an option, be used to
switch between different uids via an electrical valve.
Overview of congured blocks
An overview of congured blocks can be found by pressing twice on the [UP} key
in the main screen. The rst 4 blocks are shown. Blocks 5 to 8 will appear if the
[UP] key is pressed once again. Blocks 9 and 10 are located in the nal screen.
If several blocks are subject to overlapping times, then the block with the highest
number will be given priority over other blocks.
Rinsing
Block mode makes it possible to switch between two uids. In this case, it may be
important to rinse the humidier during the change process. This means old uid will
no longer be sprayed after the change, but only the newly selected uid. It would be
wise to measure how long it takes for the humidier to become empty and how long it
takes to ll it. These times can be entered under Emptying time and Filling time in the
Rinsing menu.

Sensor settings
Two HS-91 humidity sensors can be connected to the DZR-45. It is also possible to
connect 1 HS-10 humidity sensor to sensor input 1, instead of an HS-91.
Select the correct type of sensor as follows:
Sensor settings menu -> sensor 1 -> sensor type setting.
If desired, an offset can be dened for the sensors.
Sensor settings menu -> sensor 1 and sensor settings menu -> sensor 2.
Sensor selection: Select the sensor (1/2) that controls each hygrostat (1/2).
Hygrostat (1/2) -> Sensor selection.
General hygrostat operation
The hygrostat uses a sensor to measure current air humidity in an area. The measured
value and the congured air humidity will be used by the hygrostat to implement a
humidier or de-humidier so the required value can be achieved.
The hygrostat features various settings. Firstly, the appropriate hygrostat mode
must be selected for the application in question, after which the other settings can
be congured.
Sub-conguration
Mode Hygrostat: Standard hygrostat function with set value.
Hygrostat 1/2 -> humidity set point.
Capacity: Provides a xed output value.
Hygrostat 1/2 -> Capacity.
Hygrostat / Capacity: The output will act as a hygrostat below a set
temperature. Above this set value, the output will
be dened by the capacity value.
Hygrostat (1/2) -> Temperature. Selection.
Capacity / Hygrostat: The output will act as a hygrostat above a set
temperature. Below this set temperature, the
output will be dened by the capacity value. The
temperature setting can be adjusted as follows:
Hygrostat (1/2) -> Temperature. Selection.
Dead zone: A dead zone is an inactive, neutral area.
A dead zone of 2% and a humidity setting of 50% results in a neutral area
of 49 – 51%. The dead zone is often used to prevent oscillations.
Bandwidth: The bandwidth can be set in:
Hygrostat (1/2) -> (De)humidication -> (De)humidication bandwidth.
The bandwidth monitors the reaction speed of a humidier between
1 and 20% around the setpoint.
Minimum: A minimum can be set for any output. This can be set as follows:
Hygrostat (1/2) -> (De)humidication -> Minimum (de)humidication
settings (0-99%).

13
DZR-45
Maximum: A maximum can be set for any output. This can be set as follows:
Hygrostat (1/2) -> (De)humidication -> Maximum (de)humidication
settings (0-99%).
Figuur 9. General hygrostat operation.
Output
The hygrostat generates a 0-100% signal that corresponds to a 0-10V signal at the
outputs of the DZR-45. Relay 1 switches on if Output 1 reaches 100% (10V), it switches
off when Output 1 is below 95% (9.5V) again.
Relay 2 has the same function, but corresponds to the Output 2 level.
Thermostat
The DZR-45 is tted with a built-in thermostat for heating or cooling.
All settings for this function can be found in the Thermostat submenu.
- Set point: The desired temperature.
- Sensor selection: The sensor used (sensor 1 or sensor 2).
- Mode: Cooling: Relay 3 will be activated if the current temperature is
above the set value.
Heating: Relay 3 will be activated if the current temperature is
below the set value.
- Hysteresis: The range within which the thermostat will not change the
output.
Alarm
Every sensor readout can be activated with the DZR alarm function. It is possible to
adjust the settings in the submenus Alarm -> Sensor 1 and Alarm -> Sensor 2.
Alarm relay (4) will be activated if one or more readouts reach their minimum or
maximum values. Alarm -> Alarm delay. The alarm relay will immediately turn off if the
value falls below the set alarm level again.
