2.1
DESCRIPTION
General
The microprocessor based, Ultra-Series controller is a
highly versatile and flexible humidification controller. It is
designed primarily for STULZ Ultrasonic Humidifiers with
variable humidity output. The controller is equipped with
factory configured software designed to precisely control
the operation of this Ultrasonic Humidifier.
The Ultra-Series controller is factory programmed therefore
most applications will require no additional field setup
except for the addressing of the humidifiers. However, the
set points and their ranges are easily adjusted from the
user interface display panel. The program and operating
parameters are permanently stored in FLASH-MEMORY in
case of power failure. The Ultra-Series controller may be
configured to monitor and control a complete humidification
system consisting of multiple ultrasonic humidification units.
Depending on the Humidifier capacity, a full size UltraSeries controller may hold output power supplies for up to 8
STULZ Ultrasonic Humidifiers. When controlling groups of
Humidifiers, auxiliary control boxes, containing additional
Humidifier output power supplies, may be utilized to
achieve up to 16 humidifiers on a system. Auxiliary control
boxes contain no controller or interface display panel. They
are powered independently of the controller allowing them
to be installed near the Humidifiers they operate, resulting
in reduced wire lengths and wire size.
control box are provided with a door interlocked, main
power disconnect switch with a lockable handle. The switch
must be turned "Off" to open the door of the box. The
disconnect switch isolates power only from the Humidifiers
connected to that box.
The Ultra-Series controller is designed to manage humidity
or dew point levels to a user defined set point via
proportionally controlled output signals to the Humidifier(s).
Control set points are established to maintain the necessary
level of humidification needed to achieve the room's design
conditions. The controller has the ability to monitor the
conditions (such as humidity, temperature, supply air
velocity) via sensors or BMS control inputs. The internal
logic determines if the room conditions require
humidification. The controller communicates with the
Humidifiers the percentage output they need to be
delivering in response to the demand for humidification. The
controller responds accordingly to changes in conditions
and proportionally varies the output(s) controlling humidity
production to maintain humidity levels to the control set
point.

Controller Nomenclature
The Ultra-Series controller box contains the main operating components. The control box layout, shown in Figure 3, is a
typical layout showing power supplies for up to eight individual Humidifiers. One power supply is provided for each
Humidifier to be controlled. The higher the Humidifier capacity is, the larger the power supply for it must be. Depending on
the number of Humidifiers that need to be controlled (up to 16), the number of power supplies required may not fit inside
the Ultra-Series enclosure. In that case auxiliary control boxes are utilized to house additional power supplies as needed.

the control signal is interrupted by turning off the Control Box disconnect switch or if the control signal is lost over the
Modbus. Auxiliary Boxes must have their service disconnect switch turned off to stop the operation of the Humidifiers
connected to them while other Humidifiers are continuing to run off the Control Box and other Auxiliary Boxes.

2.6
Auxiliary Terminals
The Ultra-Series controller is equipped with customer
interface positions on terminal blocks located in the control
box. For auxiliary device wiring connections, refer to the
electrical drawing(s) provided with the unit.
2.6.1
Control Sensors
The controller is equipped with terminal positions for the
connection of sensors (temperature, or relative humidity).
If customer supplied, the sensor(s) may be a 4 to 20mA, a
0-1V, a 0-10V or a 0-5V signal to the system controller.
Parameters inside the controller need to be set
appropriately before connecting the sensors. Sensor(s) may
6
be duct mounted to monitor return or supply air and/or wall
mounted to monitor the room air to determine the
humidification demand against the control set points for
automatic control of humidity production. A wall mounted
sensor or return duct mounted sensor is typically used to
control room conditions. A duct mounted supply humidity
sensor is typically used as a high humidity limit sensor.
2.6.2
Alarm Contacts
Dry relay contacts (N/O or N.C.), are available for remote
monitoring of alarm conditions. The alarm contacts are
rated for a resistive load at 250VAC/ 8 Amps.
2.6.2.1 Summary Alarm
A summary alarm dry-contact is provided for remote
notification of an alarm condition. As programmed into the
system controller, an alarm condition activates the
summary alarm logic which energizes a summary alarm
relay and audible alarm if enabled.
2.6.2.2 Custom Alarm
In addition to the summary alarm, dry contact relays may be
optionally provided for remote annunciation of customer
selected alarm condition(s). Any alarm may be programmed
in the controller to activate the user configurable custom
alarm logic.

STULZ Ultra-Series Humidifier Controller
2.6.3
Water Conductivity Probe
To ensure proper demineralized water supply quality, the
controller is equipped with terminal positions for the
connection of a conductivity probe. The conductivity probe
is shipped loose with a 10 ft. long cable. The conductivity of
the demineralized water is monitored via the sensor (probe)
mounted in the pipe supplying water to the Humidifier (see
Section 3.3.5). The controller alerts the operator with a
"High Conductivity Pre-alarm" if the water conductivity rises
to between 5 and 20 microSiemens. Above 20
microSiemens, the controller shuts down Humidifier
operation following a 5 minute time delay and signals a
"High Conductivity" alarm.
2.6.4
Shutdown". The humidification system is automatically reenabled when the remote On/Off signal calls for the unit to
turn back on.
2.6.8
Multiple Humidifier Grouping
The Ultra-Series controller can be configured to operate two
individual groups of Humidifiers (Figure 5) via a common
Modbus.
Air Velocity Sensor
This controller is equipped with terminal positions for the
connection of an optional Air Velocity Sensor/Transmitter to
allow monitoring of the air flow in ductwork. The system
controller displays a “Low Airflow” or a "High Airflow" alarm
when the measured air velocity is outside the established
range (too high or too low). The system controller is
programmed to recognize an "Air Velocity" alarm condition
as a Non-Critical alarm. This alerts the operator of the
alarm condition but allows the Humidifier(s) to continue
operating.
2.6.5
Air Proving Switch
The controller is equipped with terminal positions for the
connection of an optional Air Proving Switch for use as a
safety feature. The switch contacts close when there is
sufficient airflow in the ductwork. The contacts open upon
loss of Airflow, triggering an alarm. The controller displays a
“Loss of Airflow” alarm when this occurs. Additionally, the
system controller is programmed to provide a “Summary
Alarm” indication. The system controller is programmed to
recognize a “Loss of Airflow” alarm condition as a “Critical
Alarm” and shut the Humidifier(s) down. The system will
automatically resume operation when airflow is restored.
2.6.6
Water Leak Detector
The controller is equipped with terminal positions for the
connection of optional Water Leak Detector(s). The water
leak detector(s) may be a spot or cable (20 ft.) type sensor.
The system controller is programmed to recognize a "Water
Leak" alarm condition as a critical alarm. Upon sensing a
water leak, the system controller shuts down Humidifier
operations and displays a “Water" alarm message. It
remains shut down until the cause has been determined
and corrected. Once corrected, the alarm can be reset.
2.6.7
Remote On/Off
If the controller is configured for the Remote On/Off option,
terminal positions are provided to connect a remotely
located, On/Off switching control device. If the Humidifier is
turned on and the Ultra-Series controller receives a remote
input signal to turn it off, the controller disables all controller
outputs and provides a status message "Off by Remote
(August, 2013)
Figure 5 - Multiple Humidifier Groups
The 2 groups can be configured with duty assignments:
Rotating, Capacity-Assist, and Bank Select.
2.6.8.1 Group Rotation
In Rotating mode, controller will rotate duty between the
Humidifier groups to promote equal run time. The rotation
time period is typically 1 week, however it may be set by the
user via the Factory menu. Call STULZ Product Support for
assistance when accessing the Factory menu.
2.6.8.2 Capacity Assist
In Capacity Assist mode, the system can be used to
maximize efficiency for conservation of energy and to allow
more precise control of humidity production during periods
of low demand. The Capacity-Assist option enables one
group of Humidifiers to proportionally handle the demand
for humidification up to their maximum capacity. If the
output of the first group of Humidifiers reaches 100%
capacity and they are unable to satisfy the demand, the
controller enables the second group of Humidifiers to
operate, controlling their output proportionally while the first
group continues to operate at 100% capacity. As humidity
conditions approach set point, the controller scales back the
proportional output control signal to the second group
accordingly until they are no longer required. At this point
7
STULZ Ultra-Series Humidifier Controller
the Humidifiers in the second group are turned off and the
Humidifiers in the first group return to proportional control.

Rotate mode.
2.6.8.3 Bank Select
Bank select is controlled by a digital input from an external
source. It selects which group will operate. The other group
does not assist. If customer provided, the bank select
control contacts must be sized appropriately. The contacts
must have a minimal rating of 24 VAC.
2.6.8.4 Proportional Humidifier/Duct Limitation
The Proportional Limitation option limits humidity production
of a group of Humidifiers based on humidity or dew point to
prevent condensation from forming on cold surfaces. For
example, Humidifiers that may be positioned near the
ceiling or floor of an AHU, where condensation may occur,
can be configured as a group with a threshold applied to
limit humidity production. In this case, the limited
Humidifiers will be in Group A (see Figure 6) and limited by
the Limit Sensors. Group A would be selected to be limited.
The Humidifiers in Group A and B operate up to their full
rated output capacity based on the demand for
humidification. As the user selected limit humidity or limit
dew point temperature limit set point is reached, the
Humidifiers in Group A start scaling output back humidity
output proportionally until it is zero output. Limitation can be
set for either Group, but based on only one limit sensor.
The enables for Proportional limitation are set in the Service
Option Loop>Startup Menu.
Multiple Humidifier controllers can be connected to a BMS or
central control terminal allowing the communication of data
and information to the BMS. Instead of sensors, control
signals from an Ethernet interface may be used to mimic
sensors used by the Ultra-Series controller to manage
humidity levels. The controller develops and transmits
control output signal(s) to the Humidifiers based on those
input signals.

Uncrating and Inspection
Mounting
The control box is designed for indoor installation only.
Mount the control box within 10 feet of the supply water
source for the STULZ supplied water conductivity probe to
reach. Avoid installing the controller in locations where
ambient temperatures are above 90°F or where the relative
humidity is above 90%. Do not install the controller where it
will be subjected to strong vibrations or bumps. Avoid
mounting in areas exposed to direct sunlight or with wide
and rapid temperature fluctuations. The control box may be
mounted to an equipment rack, a wall or a flat surface.
Secure the enclosure through the 4 mounting holes taking
care not to damage the internal components. Ensure the
mounting surface is capable of supporting the total weight
of the unit. Ensure that the areas around the enclosure
vents are free of obstructions that may impede Airflow.
(August, 2013)
When the unit is operating, the enclosure vent
openings must be completely free of obstructions.
3.3
Wiring Connections
The controller is provided with terminals for all required
field-wiring connections. Refer to Figure 3 for the location of
the interconnect terminals and see the electrical drawing(s)
supplied with the unit for all field wired power and control

before
making
AC Input
It is important that the controller nameplate be examined to
determine the operating voltage, frequency and phase of
the system. The supply voltage measured at the unit must
be within ±10% of the voltage specified on the system
nameplate. The unit nameplate is located inside the
controller enclosure. The nameplate also provides the full
load amps (FLA), the current that the unit will draw under
full design load, the maximum fuse size for circuit
protection, and the minimum circuit ampacity (MCA) for wire
sizing.
When the main power wires are connected, the electric box
has power to the main power non-fused service switch.
A separate equipment ground lug is provided within the
electrical box for termination of an earth ground wire.
3.3.2
DC Output to Humidifier(s)
Consult the wire sizing table in the Humidifier IOM to
determine the correct wire gauge, by Humidifier model, for
the length of wire to be run. Insufficient wire gauge will
result in excessive voltage drop between the controller and
Humidifier(s). Distances over 75 feet are not recommended.
STULZ recommends the use THHN or NTW, stranded
conductor (not solid conductor) wire.
3.3.3
Control Wiring to Humidifiers
CAT 5e cable, with RJ45 connector terminations; connect
the controller to the Humidifier(s) in a daisy chain fashion
(See Figure 5). Do not exceed 1,000 feet in total length.
Ensure the termination resistor (shipped loose) is plugged
on the last Humidifier in the string as shown in the electrical

mode selected. If provided by STULZ, sensors and
transmitters are shipped loose for installation by the
customer. Interconnecting field wiring should be installed in
accordance with NFPA 70 of the National Electrical Code
(N.E.C.). The wiring connections for sensors must be made
using shielded cable with a minimum AWG 22 (0.5 mm2
cross section) for each lead. Trim the length of the sensor
cables where possible to minimize wire resistance and
avoid wrapping the cable around power devices.
A remote sensor must be located so that it will properly
sense the conditions to be controlled. Refer to Sections
3.3.4.1 or 3.3.4.2 when mounting sensor(s). Refer to Figure
3 for the location of the controller interface terminals and to

STULZ Ultra-Series Humidifier Controller
4.0
4.1
OPERATION
General Theory of Operation
This Ultra-Series controller is designed to control the output
of an ultrasonic humidification system in a space or process
application to humidity levels as defined by the user.
Humidified air is supplied to the conditioned space as
needed to maintain the relative humidity or dew point
control set point. The controller may also be networked with
a group of Humidifiers to manage their outputs as a system.
The controller I/O module includes inputs and outputs as
depicted in Figure 11:
4.1.1.2 Dew Point Control
The controller calculates dew point based on signal inputs
from temperature and humidity sensor(s) to manage
humidity production against a dew point control set point.
4.1.1.3 Proportional Control
The controller uses an external input signal representing 0
to 100% output to control humidity production.
4.1.2
Operating Modes
There are 6 operating modes for the controller depending
on how many and what types of inputs are used. The
operating mode has been pre-set by the factory and should
not require adjustment. BMS Signal indicates the input is
sourced by the serial BMS interface. Sensor indicates the
input is a physical signal and may originate from a sensor
or a voltage/current generated by another control system.

4.1.2.1 Room Control
The controller may be configured for room installations with
only one control input. In room installations the controller
maybe configured to manage humidity production based on
a control signal from a return air humidity sensor or
optionally from a relative humidity and temperature sensor
for dew point control or, a signal from an external controller
or BMS can be used (Modes 1 & 2).
Figure 11 - Control Inputs and Outputs
4.1.1
Humidification Control
The method of operation depends on the controller's
programmed operating mode. Control takes place by
means of the controller analyzing signal inputs from
sensor(s) and/or from an external supervising controller or
Building Management System (BMS).
4.1.2.2 Return Air Duct Monitoring (DAH Units)
When used for duct installed, DAH Humidifiers in air
handling units, two inputs may be utilized. Input 1 is the
control for the humidity in the return air duct and input 2 as
a proportional high limit signal downstream of the
Humidifier. The inputs may be from a BMS/external
controller and/or remote sensors (Modes 3 - 6).
4.1.1.1 Humidity Control
The controller responds to relative humidity sensor signal
input(s) to manage humidity production against a relative
humidity control set point.
12
(August, 2013)
STULZ Ultra-Series Humidifier Controller
4.1.3
P/I- Proportional/Integral Control
The controller calculates proportional control output
signal(s) based on the analysis of sensor input signals,
which determines the amount of humidification needed (see
Figure 12).
Signal 1 represents the return air humidity and is calculated
by the controller as a percentage value compared to the
maximum control set point value for input 1, taking into
account the prop band. Signal 1 is compared to the
maximum control set point value for input 1 resulting in a
control value that will be proportional to signal 1. Signal 2
represents the limit humidity and is calculated as a
percentage value for input 2 taking into account the prop
band. Signal 2 is compared to the maximum control set
point value for input 2 resulting in a control value that will be
proportional to signal 2. The control output signal to the
Humidifier(s) will be directly proportional to the combined
input signals by the following process:
Signal 1 x Signal 2
100
If input 2 is not used, the controller only works with
reference to signal 1. The effect of integral on the control
signal (Signal 1) has been neglected from the above
calculation for simplification. With integral control, the
added element of time is factored into the Humidifier output
algorithm. The integral value is used to gradually adjust the
proportional output when the calculated output does not
move the process variable closer to set point in a given
period of time. Decreasing the integral value decreases the
interval for the output corrections (speeding the rate of
adjustment). Increasing the integral value increases the
interval for corrections (slowing the rate of adjustment). The
P/I control factors are hard coded in the controller and
cannot be user adjusted.

any programmed alarm condition. This illuminates the alarm
key and activates an audible alarm. A summary alarm also
energizes Normally Open/Normally Closed summary alarm
contacts to remotely monitor alarms. If a Critical alarm
condition is detected, a summary alarm will be
accompanied by Humidifier shutdown.
4.5.1.2 Custom Alarms
A Custom Alarm (user configured) is activated upon
detection of one or more individual alarm conditions as
selected by the operator in the Service>Options>Custom
menu loop (see Section 5.5.4.3.2). When a custom alarm
condition is detected, the alarm key illuminates and a
designated set of N.O. & N.C. Custom Alarm relay contacts
are energized to provide remote indication of the selected
alarm condition(s).
For example, it may desired to have a remote notification
when a High Conductivity pre-alarm is detected, giving
notice that the mineral content of the supply water is
approaching an unsafe level. This gives an alert before the
mineral content of the water reaches the high conductivity
threshold and the Humidifier is shut down.
The controller may be factory configured to activate up to
four Custom Alarms. One user configurable Custom Alarm
with relay contacts is provided as a standard and up to
three additional may be provided as an option.
4.5.1.3 Customer Alarms
A customer provided digital (on/off switching) alarm sensor
may be connected to the terminals provided in the electric
box. This may be for any site specific alarm condition the
user wishes to monitor that may or may not be provided in
the standard alarms menu; i.e. gas detection, intrusion
alarm, etc. Upon detection of a customer alarm, the alarm
key illuminates and the alarm display screen provides a
message indicating a customer alarm message. The screen
message "Customer Alarm 1" will appear (default) in the
controller display or the user may re-configure the controller
to display any alpha-numeric message desired, up to 20
characters long, in the Service>Options>Custom Setup
menu loop (see Section 5.5.4.3.1). One Customer alarm
(August, 2013)
STULZ Ultra-Series Humidifier Controller
input is provided as a standard and up to two additional
customer alarm inputs may be enabled as an option.
4.5.1.4 Air Flow Proving (DAH option)
When the Airflow proving switch detects an insufficient air
flow condition, the system controller will display a "Loss of
Air Flow" alarm and shut down the Humidifier(s). When the
Airflow problem is corrected and the alarm is re-set, the
Humidifier(s) will automatically resume operation.
4.5.1.5 Air Velocity Monitoring (DAH option)
The Humidifier outlet air velocity may be monitored by a
sensor. If enabled, the controller provides a display screen
with the current air velocity. An air velocity alarm will be
triggered if the velocity falls outside a selectable minimum
and maximum range.
4.5.1.6 Low Temperature Limiting (Optional)
The Humidifier return air temperature may be monitored by
a sensor. As the low air temperature threshold is
approached, the controller linearly limits the humidification
signal. If the return air temperature drops below a
selectable threshold temperature, a low temperature alarm
will be signaled. The controller is programmed to shut down
the Humidifier and drain the reservoir upon sensing a low
temperature alarm to prevent damage due to freezing.
4.5.1.7 Cabinet Temperature Monitoring
A digital output signal from the controller turns on a cooling
fan located inside the control cabinet when the internal
temperature rises to a threshold plus dead band. If the
enclosure temperature continues to rise, the controller
activates a high temperature alarm and stops Humidifier
operation. The "Fan On" set point and "High Cabinet
Temperature Alarm" threshold are adjustable in the
Control>Alarm Set menu loop (see Section 5.4.2).
4.5.1.8 Water Conductivity Monitoring
A sensor installed in the water supply piping permits
monitoring the water conductivity as a measure of
determining when the mineral content is too high. This will
ensure clean, mineral free mist production. The supply
water quality specified for STULZ Ultrasonic
Humidifiers during normal operation should not exceed 5
microSeimens. The controller will provide a pre-alarm
message if this water conductivity rises above 5
microSeimens for more than 5 minutes. If water conductivity
rises above 20 microSeimens for more than 5 minutes, the
controller will shut down the Humidifier(s) and provide a full
alarm text message and indicate a summary alarm
condition, energizing the N.O./N.C. summary alarm
contacts, and optional audible alarm.
4.5.1.9 Water Leak Detection (Optional)
The Humidifier controller may monitor water leaks via
optional water detector(s). Refer to Section 2.6.6. Upon
sensing a water leak, the controller activates the summary
(August, 2013)
alarm logic and displays a "Water" alarm message. The
controller recognizes a water alarm as a Critical Alarm and
shuts down Humidifier operation.
4.5.2
Remote On/Off
For Remote On/Off operation, terminal positions are
provided to connect a remotely located, On/Off switching
control device. If the Humidifier is turned on and the Ultra
series controller receives a remote input signal to turn off
the Humidifier, the controller disables all control outputs and
a message "Off by Remote Shutdown" appears in the main
display screen. The system will automatically be re-enabled
when the remote On/Off signal calls for the Humidifier unit
to turn back on.
The control device may be an On/Off switch, thermostat or
a humidistat. If customer provided, the remote On/Off
control contacts must be sized appropriately. The Remote
On/Off contacts must have a minimal rating of 24 VAC.
Refer to the electrical drawing included with the unit for the
electrical specifications and for wiring details.
4.5.3
Automatic Drain Cycle
The controller is configured to activate a drain cycle of the
Humidifier reservoir(s) during periods of inactivity. This
ensures a fresh supply of water in the reservoir. If the total
demand for humidity production has been below 10% for
the time interval for the drain cycle is programmed (Default
of 72 hours, the humidifiers will be commanded to drain.
The idle time and drain duration may be adjusted in the
Service menu (see Section 5.5.1.2). When a drain cycle is
initiated due to the idle time elapsing, the following occurs:
1. Humidification stops.
2. The drain valve is energized open.
3. At the end of the drain duration time, the drain valve
closes.
4. When a demand is present, the fill valve opens and
humidification returns to normal.
The water reservoir is emptied entirely during the auto drain
cycle. If there is a demand for humidification, the drain cycle
is interrupted. The drain valve closes and the fill valve
opens. When the water level in the reservoir is at an
appropriate level, the unit begins producing humidity.
4.5.4
Manual Drain
The operator may manually drain the reservoir of an
individual Humidifier by energizing its drain solenoid valve.
This is accomplished with the controller by accessing the
Manual Control screen from the Service>Humid menu loop
(see Section 5.5.1.14).

4.5.5
Communication with the Controller
It is possible for the controller to communicate in a variety
of ways.
4.5.5.1 Serial Communication
Using an expansion card, the controller may be connected
to a BMS for monitoring and control of data points using a
choice of available serial communication protocols (see
Section 5.5.7).
Loading New Software
The procedure must be executed if new software is emailed
to a site and then uploaded onto a Smart Key (STULZ
typically sets up Smart Keys before shipping them to a site).
After downloading the emailed software onto a Smart Key,
the technician must upload the new software from the
Smart Key into the controller.
1. Turn the controller off.
2. Disconnect the Interface Display Panel from the
Controller I/O module.
3. Plug-in the Smart Key.
4. Turn the controller on.
5. Wait until the LED’s stop blinking on the Smart Key
and the start button illuminates.
6. Press the start button on the Smart Key.
7. When the upload operation is complete, a chime
sounds.
8. Turn the controller off.
9. Unplug the Smart Key.
10. Turn the controller on.
4.5.6.1 Multiple Humidifier Units
The Ultra-Series controller is designed to be the central
terminal for up to 16 Humidifiers (Figure 5). This enables
the monitoring and management of the operation of multiple
humidifiers from a single Ultra-Series controller interface
display panel. The controller interface display panel allows
access to the data and operating functions for each
networked Humidifier via additional menu screens. See
Section 5.5.1.3 to set up Humidifier groups.
When serial communication is utilized, the controller
incorporates a communication port that is field connected
through an optional serial interface to a central BMS. Inputs
& outputs are remotely monitored (address readable) and
remotely controlled (address writable) via a BMS control
system that communicates with the controller via Modbus
RTU, BACnet MS/TP or IP based protocols such as
BACnet over IP, HTTP, or SNMP protocols. Each E-Ultra
Controller added to the network must be configured for
BMS communication.
4.5.5.2 Direct BMS Control
The output of the unit may be controlled directly via a
proportional current or voltage signal in certain modes. In

5.5.1.1 Humidifier Cut-in/Cut-out
The first screen in the Service->Humidifier loop allows
adjustment of the cut-in / cut-out setpoints for the control
and limit inputs. If the control is set up for humidity, the cutin and cut-out are in terms of %RH. If the control is set for
dew point, the cut-in and cut-out is in terms of °F or °C
(depending on the selection of US or SI units). If a limit
sensor is setup, the cut-in and cut-out values appear,
again in RH or dew point.
The restrictor imposes a scaling on the actual output of
each group of humidifiers. In the example above, Group A
will physically output 0 to 100% over the range of the
called for humidification of 0 to 100%. Group B will
physically output 0 to 90% over the range of the called for
humidification of 0 to 100%. It is equivalent of taking the
output of control output and multiplying it by 0.9. This is
useful if the installation has a group of humidifiers that
would cause condensation due to proximity to objects. The
output of the humidifiers can be prevented from reaching
maximum capacity.
5.5.1.2 Humidifier Drain
This screen is used to set the interval and time duration for
the automatic drain cycle to occur when the Humidifier(s)
have been inactive (no command to humidify). The "Drain
Now" field to initiate a manual drain cycle by changing
"No" to "Yes". The Humidifier drain valve will stay open
for the duration set in the "Drain Time" field and then
return to the closed position (for either Manual or Auto
drain). The word "Draining" appears in the status field
when in the Auto or Manual drain mode. The bottom line
shows the number of hours left until a drain will occur. It is
reset to zero whenever there is a call for humidification.
Humidifier Drain
Cut-in and Cut-out work based on the set point and set the
span of the control range. In the example below, the
control cut-in is set to -4%RH. Assume the humidity set
point is 45%RH. With this value of the cut-in, 100%
humidification will be reached at 41%RH. The cut-out is
the point at which 0% humidification occurs. Again, the
control would be at 0% when the humidity reaches
46%RH. The span is the difference between the cut-in and
cut-out and in this case over a 5%RH change in RH, the
output would go from 0 to 100%.
In the example below, the limit goes from 0% at the set
point to 100% at 5%RH below the set point. Cut-in must
always be less than cut-out.

5.5.1.4 Change Humidifier Modbus Address
If a new Humidifier is added to an existing group of
multiple ultrasonic Humidifiers, it must be configured with a
new unique address for Modbus communication. From this
screen a Humidifier may be selected and its assigned
Modbus address number may be changed. A new
Humidifier is typically shipped from the factory with its
Modbus address set to one. In this case it will need to be
assigned a new address to differentiate it from the current
Humidifier in the group that is already addressed as
number one.

humidifier is responding to the address shown as
the Change to Hum number. New Hum in use
indicates that a humidifier is responding to the
Change to Hum number already. Wait is displayed
during changing of the display number, waiting for
the assignment change to be complete. This

(August, 2013)
5.5.1.4.1
Procedure to Change Humidifier
Assignment:
With power turned off at the control box, complete the
Modbus and power wiring connections to the Humidifier to
be added.
Turn Off all the Humidifier circuit breakers inside the
control box and any in auxiliary boxes (see Figure 3 Control Box Internal Layout; item 17), except the one
power supply for the Humidifier to be addressed. This
isolates the existing Humidifiers from the Modbus allowing
only the address of the new humidifier to be changed.
When power is re-applied to the control box (and with the
circuit breaker turned on only for the new Humidifier to be
addressed in the appropriate control or auxiliary box),
bring up this screen. Go to the last line and change the
“NO” to “Yes” indicating the desire to change the address
of the humidifier. The third line in the screen displays
"Wait” while the E-Ultra sends out the change command
and waits for a response at the new address. The third line
will change to New Hum in Use” and the fourth line will
change to “Current hum not ready” indicating it is
communicating using the "Change to Hum" address and
not the original address. If the third line displays "New Hum
Available", it indicates the Humidifier did not accept the
change.

If multiple Ultra-Series controllers are connected to a BMS,
each controller must be configured with a unique address
for BMS communication. This is done by programming the
serial interface port from a lap top. Contact STULZ Product
Support for assistance (see Section 9.0).
BMS Communication
SERVICE MENU software
Run Hours
5.5.7.1 Direct BMS Control
The controller may be configured to accept proportional
analog signals that mimic sensors. The controller will act
on that signal whether it comes from a real sensor or a
BMS analog output. Refer to Appendix A for the UltraSeries controller BMS parameters.
BMS COMM
Factory
The BMS Comm menu is used to set up parameters to
allow a Building Management System (BMS) to interface
with the controller. The unit may be connected to a BMS
for monitoring and control of data points using a multitude
of different serial communication protocols.
When BMS communication is utilized, the controller must
be equipped with an expansion card designed for one of a
variety of serial communication protocols available.
A RS-485 serial port is available for Modbus or BACnet
MS/TP protocols and a 10BaseT port is available for
TCP/IP based protocols such as BACnet over IP, BACnet
over Ethernet, SNMP or HTTP.

5.5.7.2 BMS Set-up
The following menu screen is accessed from the
Service>BMS COMM screen to set-up the parameters for
a BMS interface to monitor controller operation for the
serial-based networks such as BACnet MS/TP. Units using
the BACnet over IP, BACnet over Ethernet, or HTTP
protocols do not need to change anything in this menu
loop.
BMS Communications
Address:
Baud Rate: 19200
Comm Timeout:
Protocol: BACnet
1
10m
The BMS address and baud rate have meaning only on
RS-485 networks and with the serial protocols of Modem,
Modbus RTU, Commission, and Carel. The baud rate is
fixed for BACnet. Systems utilizing a 10BaseT interface
should use the defaults of address 1, baud rate 19200,
and protocol BACnet.
If the mode selected uses a BMS supplied signal via the
communications interface (modes 1, 3 or 5), the loss of
BMS active (which is held true as long as the toggling of
the keep alive is switched between 1 and 2), will simply
cause the system to shut down and display “Off by
Network”.
The general procedure is to set up variables like return
humidity/proportional control and then toggle the value (1
or 2) to the BMS "keep alive" address.
For further details on utilizing BMS control, contact STULZ
Product Support (see Section 9.0).

The top line reflects the type of humidifier that is being
controlled.
The number of humidifiers is set to number of humidifiers
attached to the E-Ultra Controller. This should be set to the
exact number of humidifiers. If it is set too high, time is
wasted in the Modbus communications trying to access
the non-existent humidifiers.
The line with “Humidifier Temp” is set to YES if the
humidifiers have nebulizer temperature sensors.
The line with “B2 is Temperature” only appears on the
small controller and allows the use of a control
temperature sensor instead of a limit humidity sensor. This
allows a small controller to have dewpoint control.
BMS Keep Alive set to Yes requires the BMS system to
toggle the keep-alive parameter between 1 and 2 at a
maximum of 10 minutes between changes. The purpose is
to allow the E-Ultra to determine control outputs when the
BMS goes off line.
Integration time is the number of cycles used in the PI loop
for Humidity or Dew Point Control. The larger the number,
the longer it takes to wind up the integrator and increase
the percentage output when the humidity does not change.

6.1
MAINTENANCE
General
7.0
7.1
Because conditions vary greatly, individual maintenance
schedules must be determined for each location, based
upon periodic examination of the controller.
Check for corrosion on the exterior of the enclosure.
Touch-up the finish if required.
WARNING
Power is still present inside the control box when
the On/Off switch on the enclosure door is Off.
Turn off main supply power before performing
maintenance to the interior of the box.
Check the interior of the enclosure for accumulated dust or
dirt. Vacuum if required.
Check for corrosion on the electrical connections. Clean
corrosion if necessary and apply anti-corrosion grease.
Periodically, check and tighten all terminal connections.
Check the interior of the enclosure for signs of
overheating. If evidence of overheating is observed,
Ensure the vent openings are free of obstructions and the
vent fan operates when the cabinet temperature is above
104°F.
A system should be established for trend analysis of
problems, defects and deficiencies noted by operators and
discovered during maintenance inspections together with
the corrective actions taken. For maintenance assistance,
contact the STULZ Product Support.
TROUBLESHOOTING
General
The Ultra-Series controller is designed for continuous and
dependable operation. In the event that a problem is
encountered with the humidification system, the system
controller may be used to diagnose the cause.
The controller signals an alarm condition when the red
backlight LED is illuminated behind the alarm function key.
An alarm indication is accompanied by a screen text
message with a brief description of the cause (See Alarm
Screen Messages, Section 5.3.4). Often the remedy is
simple to determine by reading the alarm message i.e.
“High Conductivity Alarm” (Check supply water quality).
The following abbreviated guidelines are included to assist
in troubleshooting the system due to operational or
performance problems. Refer to the Humidifier IOM for
troubleshooting guidelines when there are system
performance issues. If the problem can’t be resolved using
the alarm screens and the guidelines, contact STULZ
Product Support for assistance (See Section 9.0).
Problem: “Alarm” Lamp is ON
1. Use the system controller to check the Alarm display
message(s).
2. Identify and correct cause of alarm condition.
3. Reset if necessary.
Problem: Control Is Erratic
1. Wiring improperly connected or broken.
2. Wires shorted. Check all wire connections to ensure
they are tight and that no shorts are present. Also check
wiring against the schematic diagram included with the unit
to ensure the wire terminations are correct.
WARNING
Keep hands, clothing and tools clear of live
electrical terminals. Turn off all power to the unit
before conducting any troubleshooting or repair
procedures unless the procedure specifically
requires the system to operate.

Control I/O Module Signal LED's
The control I/O module includes 3 LED's (red, yellow and green) that provide information on the operation of the control
module and status of the connection to the pLAN. These signal LED's are positioned adjacent to the yellow, "Power On"
LED (see Figure 4). The signal LED's may be used for diagnostic purposes if a problem arises.
