Overview

Chapter

This chapter gives an overview of the Proliphix Internet Managed Thermostats (IMT)
Series Network Thermostats, as well as how to access the IMT550 using a Web
browser.

The IMT550 series of thermostats are powered by either Proliphix Ethernet Power
Adapters, Power over Ethernet, or via 24Vac from the HVAC system, and include the
following features:

Ethernet

IMT550c X X X

IMT550w X X X

DHCP Assigned IP Addresses

The IMT550c and IMT550w thermostat ship directly from the factory enabled to
perform as a Dynamic Host Configuration Protocol (DHCP) client. DHCP is an
established standard used to assign IP addresses automatically after each network
device is inserted into the network or when the device experiences a power cycle.
DHCP allows devices on your local network to receive their Internet Protocol (IP)
addresses automatically from an attached DHCP server typically located within a
local router.

If your file server or router supports DHCP, then your Proliphix thermostat
automatically retrieves an IP Address, Gateway Address, Subnet Mask, and DNS
server address from the DHCP server on your network.

CHAPTER 1: Overview

Proliphix strongly recommends that a DHCP server be installed and operational

Note

Connecting the Thermostat to the Local Network

in your network prior to installing the thermostat.

If a DHCP server is unavailable on your network, your thermostat will default to
the 169.254.111.111 IP address. Note that this address is not unique to your
network if more than one thermostat is installed on a network without a DHCP
server. That is, there will be multiple thermostats on the network with the same IP
address (i.e. 169.254.111.111). Addressing conflicts will exist and most of the
thermostats will be inaccessible. You can use the lcd interface to set the IMT550 to
a static IP address if no DHCP server is available.

This section describes how to connect your IMT550c and IMT550w thermostats to
your local data network. This connection enables you to conveniently and efficiently
configure your thermostat using a browser on your laptop or desktop personal
computer. If a broadband connection is available on your local network, you can also
remotely manage and configure your thermostat via the Internet.

To connect the thermostat to your local network:

 For the IMT550c, use a standard Ethernet patch cable and complete the

connection of your thermostat(s) to the local switch or router. Your thermostat(s)
should automatically communicate with the local DHCP server and be assigned a
unique IP address.

 For the IMT550w, use the lcd interface and configure the wireless settings to

match your local wireless network.

Remote Management

You can manage the IMT550c and IMT550w thermostats using a web browser on a
local area network (LAN) or remotely though the Internet after proper authentication
at the Proliphix Web Site (www.proliphix.com).

Determining the IMT550 IP Address

Your Proliphix IMT550 ships from the factory capable to support the DHCP mode for
assigning an IP address to your thermostat. See the DHCP Assigned IP Addresses

(page 1-1) for more information.

Before you access and control your Proliphix IMT550 through either the lcd screen or
more comprehensively through the Web browser, you must know the IP address of the
thermostat.

To retrieve the IP address on the lcd screen on the front of the thermostat:

1 Press the Proliphix logo on the bottom right side of the lcd screen.

1-2 Internet Management Thermostat Configuration Guide, Release 1.0

Part No. 600-03001-550, Rev. 1

Beta Draft Confidential

2 Press Network.

3 Press IP Address.

The IP Address screen displays the Address Method and URL (IP Address).

Accessing the Web Interface

To access the initial Web page of the thermostat, enter the unique IP address initially
assigned via DHCP in your browser window. For example:

http://192.168.0.247

Where 192.168.0.247 is a unique IP address initially assigned via DHCP.

Most of the Web pages conform to a standard format which is maintained for both
local and remote thermostat access. A banner at the top of each page contains the
following information for each thermostat:

 Current date and time

Accessing the Web Interface

 Host name of the thermostat

 Model number

Each thermostat page also includes tabs which enable direct access to all other Web
pages on the thermostat. The Web browser displays each page in a table format. Each
feature table is organized by rows of functions, in a left to right direction as follows:

 Field name

 Function status

 Function control (text boxes and drop-down selections)

Logging In to the Thermostat

The IMT550 Series thermostats require password authentication prior to accessing the
Web pages that enable you to control or manage the thermostats. The username and
password is as follows:

Username: admin

Password: admin (default)

You can change each of these passwords within each account after the initial

authentication. For more information, see Password Settings (page 2-47).

To log in to the thermostat and access the Web pages:

1 Open a Web browser.

2 Enter the IP address of the thermostat. For example:

http://192.168.0.247

The thermostat scheduling feature is organized in a hierarchy. You use Profiles (up to

into four events, each of which supports temperature settings for both heating and
cooling, and fan scheduling to provide periodic air flow.

Each Profile supports the following four non-overlapping events of time (within 24
hour period) in which you can independently specify heat, cool, and fan schedules.

Stage Delays

Compressor Delay Specify the minimum time (in minutes) between successive

heating, cooling or heat to cool and cool to heat cycles in heat
pump applications. This parameter ensures a safe heat pump
compressor delay or off time guaranteed between cycles. This
parameter may also be used in fuel burner mode, whereby this
parameter ensures a safe A/C compressor delay or off time
guaranteed between A/C cycles.

completion of the previous cycle. This is a diagnostic

feature and should not be left in this state or compressor

Maximum Cycles

Maximum Cool Cycles/Hour Limits the number of cooling cycles every hour. If this value is 3

(default) for example, a cooling cycle can be invoked once in
each of the three 20-minute hourly intervals. In this example, a
subsequent call for cool after the initial cool call in a 20-minute
interval is deferred until the start of the next 20-minute interval.
This feature can be defeated by the user if changes are made to
override the setpoint settings, either at the thermostat or via the
Web page. This feature only applies to scheduled temperature
settings.

 Disabled – This feature is disabled and unlimited cooling

cycles are allowed.

hour.

Maximum Heat Cycles/Hour Limits the number of heating cycles every hour. If this value is 5

(default) for example, a cooling cycle can be invoked once in
each of the five 12-minute hourly intervals. In this example, a
subsequent call for heat after the initial heat call in a 12-minute

A/C Humidity Control

A/C Humidity Control Select a relative humidity value from 10% to 90%. when

Enabled. When the measured RH rises above a preset threshold,
the HVAC cooling cycle is initiated. The cycle continues until
the humidity level falls 5% below the trigger level or until a heat
setpoint is encountered. When a heat setpoint is encountered, the
HVAC heating cycle is invoked. After the heat setpoint has been
satisfied, the HVAC cooling cycle (to satisfy humidity
requirements) is delayed for 5 minutes. Humidity control is
intended for moderate moisture control. High humidity
environments should also include secondary dehumidification
equipment.

 Disabled – This feature is disabled and the A/C system may

not be used to reduce humidity.

 Enabled – 10% – 90% - Humidity threshold expressed in

5% increments.
