Overview
The Proliphix family of Network Thermostats (NT) provide a rich set of innovative
features including the ability to configure settings through a graphical interface either
locally or from any remote location. The thermostats can be connected via secure
wired Ethernet to a home, small business, or light commercial data network.
This guide describes how to physically install the basic series (NT10e/NT20e) as well
as the professional series of thermostats (NT100e/h, NT120e/h, NT125e/h, and
NT150e/h). Any instructions or guidelines that apply to a specific thermostat model
are noted within this guide. The following model-specific features are important to
note during the installation:
NT10e/NT20e (Basic Series)
Powered by Proliphix Ethernet Power Adapters (EPA20/60).
(NT20e only) Two remote thermal sensors; either Analog or Thermistor.
Single-stage HVAC (1h/1c).
Heat pump HVAC with auxiliary heat (2h/1c).
NT100e/h, NT120e/h, NT125e/h, and NT150e/h (Professional Series)
Powered by Proliphix Ethernet Power Adapters (EPA20/60) or Power over Ethernet (PoE, 802.3af)
power injector equipment. The “h” version models support HVAC system power with 24VAC.
Two remote thermal sensors; either Analog or Thermistor on the NT120e/h, NT125e/h, and
NT150e/h.
Dual-stage HVAC (2h/2c).
Heat pump HVAC with auxiliary heat (2h/1c).

to the components on the thermostat’s circuit module. Do not remove the
thermostat from the protective bag until you are ready to install the thermostat.
The following tools are required to install the Proliphix thermostat:
#1 or #2 Phillips head screwdriver.
Drill with a 3/16” or 7/32” bit.

Installing the Thermostat
Installation Guidelines
Use the following guidelines to install the Proliphix thermostat:
If you are replacing an existing thermostat, mount the Proliphix thermostat in the
Tip
same location as the thermostat in which you are replacing.
Install the thermostat on an inside wall, about 5 feet (1.5m) above the floor, and in
a room that is used often.
Install the CAT5/CAT5E/CAT6 cabling from the wiring center to the thermostat
installation site.
Install the thermostat in an area or room with adequate air circulation and where
there are no unusual heating/cooling conditions, such as: sunlight, near a lamp,
radio, television, radiator register, or fireplace; near hot water pipes in a wall; near
a stove on the other side of the wall, on a wall separating an unheated room; or in
a draft from a stairwell, door, or window; in a corner or alcove; or behind an open
door.
Beta Draft Confidential
Caution
Install the unit after all construction work and painting is complete.
Install the unit in an unobstructed location where there are no objects on the wall
above or below the thermostat or other obstructions (such as furniture) restricting
vertical airflow.
It is not necessary for the thermostat to be level.
Prior to installing or servicing the thermostat, turn off electricity to the HVAC
system; do not turn electricity back on until all work is complete.
Do not jumper wires together to test the system. This may cause harm to your
HVAC system and damage the thermostat, and therefore void the warranty.
All wiring must conform to local codes and ordinances. The distance between
CAT5/CAT5E/6 cables and HVAC cables should be a minimum of one inch.

Before You Begin
If you are removing an existing thermostat, Proliphix recommends that you label each
connection as you remove the wiring. You will use these same wires (and labels) when
you connect the Proliphix thermostat (page 4).
Use the following steps to remove an existing thermostat:
1 Turn off power to the HVAC system or the fuse/circuit breaker panel.
2 Remove the cover from the existing thermostat. If the cover does not snap off when
pulled firmly from the top or bottom, check for a screw(s) that may be used to secure
the cover.
3 Disconnect each wire. Label the wires with the terminal designation from the existing
thermostat. Place the label about 1/2” away from the end of the wire to allow for
stripping of the ends. Note: If this is a new installation, obtain the wire designations
from the HVAC installer.
4 Remove the existing thermostat from the wall.
Before You Begin
Installing and Wiring the Thermostat
This section describes a two-step installation process in which you install (or mount)
the thermostat base plate and wire the thermostat.
Installing the Base Plate
Perform the following steps to mount the thermostat base plate on the wall:
1 Review the Installation Guidelines on page 2 and position the base plate in an
appropriate location on the wall. Ensure the location allows you to access and pull the
wires through the opening in the base plate.
2 Using a pencil, mark the center of the screw holes on the left and right side, and
bottom center of the base plate.
3 Remove the base plate from the wall and drill three holes at the marked locations: for
drywall, drill 3/16” holes; for plaster, drill 7/32” holes.
4 Gently tap the wall anchors (included in the packaging) into the drilled holes until
they are flush with the wall.
5 Pull the wires through the base plate and position the base plate over the screw holes.
6 Attach the base plate to the wall using three 1" screws (included in the packaging).

Wiring the Base Plate Terminals
Use the instructions in this section to wire the base plate terminals as follows:
Wire the NT10e/NT20e base plate for fuel burner HVAC (page 4) and heat pump
HVAC (page 6).
Wire the NT100e/h, NT120e/h, NT125e/h, and NT150e/h for fuel burner HVAC
(page 4) and heat pump HVAC (page 6).
Fuel Burner HVAC
Use the instructions in this section and refer to Table 1 and Figure 1 to wire the base
plate for fuel burner HVAC. Refer to the labels you placed on the wires when you
removed the existing thermostat (page 2).

Configuring Remote Sensors for the NT20, NT120, NT125, and
NT150
The Proliphix thermostat provides two remote (external) sensor ports. This release
supports Analog and Thermistor sensors (go to Proliphix.com for a complete list of
supported sensors).
Analog sensors convert temperature measurements as Fahrenheit degrees to a voltage
which can be sensed by the thermostat. Analog sensors are active devices which
require power from the thermostat. The Analog sensor is polarized and must be
connected as shown in Table 3.
Thermistor sensors are passive devices which represent thermal measurements as
electrical resistance. Thermistors do not require power from the thermostat. The
Thermistor sensor is not polarized; either lead can be connected as shown in Table 3.

Installing and Wiring the Thermostat
Mounting the Thermostat into the Base Plate
The Proliphix thermostat contains jumpers to configure the HVAC power settings.
The power settings determine which HVAC power source (RH or RC) is configured to
turn on each HVAC system (cool, heat and fan). Most applications use only RH
power. The Proliphix thermostat is shipped from the factory with the “RH Only”
configuration.
Table 5 lists the possible HVAC power configurations. RC and RH are connected with
J1 inserted.

2 Snap the bottom of the thermostat securely into the base plate.
Verifying the Thermostat’s Operating Status
This section describes the procedures you can use to verify that the heat, cool, and fan
controls are operating properly on your thermostat. Before you begin, verify that the
HVAC system’s power is set to “On” and press HVAC on the thermostat panel.

Troubleshooting
Use Table 7 to troubleshoot potential issues with your thermostat.
Table 7 Troubleshooting Tips
Condition Possible Cause
LCD display is blank If using a Proliphix EPA to power your thermostat:
Check power to the EPA.
Check the wiring on the EPA punchdown terminal (use the T568A wiring scheme).
Use a 110 block punchdown tool to ensure proper connection.
Check the blue and brown pairs on the Ethernet cable connected on screw terminals 1 and
2.
Verify that jumper J3 is on both pins (In position)
If using PoE to power your thermostat:
Verify that jumper J3 is not connected to both pins (Out position).
Verify the PoE equipment is sending power to the thermostat. See your PoE equipment
documentation.
Verify that Ethernet wiring is securely attached to terminal screws.
If using an “h” model thermostat:
Verify that the Common from the primary transformer source (either RH or RC) is
connected to the C terminal.
Either RH or RC (24v source) must be connected.
Verify the HVAC system is powered on.

Use a 110 block punchdown tool to ensure proper connection.
Verify that the Ethernet patch cable is in the correct RJ45 port of the EPA (port 1 connects
to punchdown 1, etc.)
Verify that the Ethernet patch cable is connected to a working hub, switch, or router.
Verify you increased the heat set point higher than the temperature reading and the
thermostat is in heat mode (see page 11).
