Communication with the Controller
4.5.5
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).
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
this method of control, the humidification output level of the
Humidifiers is directly controlled by a proportional/integral
input signal from the BMS. (i.e. 4mA = 0% output; 20mA =
100% output)
Loading New Software
4.5.6
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.
