Introduction
Thank ou for purchasing the BAYweb Thermostat. You now have one of the most advanced
Heating, Ventilating, and Air Conditioning (HVAC) control s stems available toda .
This thermostat is easil installed b home owners or HVAC professionals. It can be used to
replace an existing thermostat or for installation with new heating or cooling equipment.
This model of the BAYweb Thermostat (BW-WT2) is designed for use with conventional or
heat pump based s stems that use single or multistage stage control.
About This Manual
This manual contains the information necessar for installing and operating the BAYweb
Thermostat. However, since installations ma var , these instructions ma not cover all details
or variations in the equipment supplied or ever question that ma possibl arise during use.
If a question or situation develops which is not answered directl in this manual, contact
BAYweb support for specific answers and advice.
You should become familiar with the contents of this manual before the thermostat is put into
service. This is particularl important with regard to the safet precautions listed in the

www.ba web.com.
CAUTION: Read, be sure to clearl understand, and then carefull follow all of the
directions and procedures included in this manual. Failure to adhere to the
guidelines and specific instructions provided could cause equipment damage and
serious personal injur or death.
Safety Precautions
Low voltage thermostats, including the BAYweb Thermostat, use 24 VAC control signals
limited to 3.2 amperes to interface to our furnace and air conditioning equipment. These low
voltage control signals do not normall represent an electric shock hazard unless used in an
environment for which the equipment was not designed for, such as a wet location.

Installation
Overview
Installing the thermostat is a relativel simple process and t picall takes from 10 to 30
minutes to complete. You should consider the current outdoor temperature. If unexpected
problems occur, ou do not want to risk freezing or overheating while ou are sorting out the
problem.
You will need screwdrivers, a wire stripper/cutter, and a drill for installing the wall anchors to
complete the installation. A volt/ohm meter can be helpful for troubleshooting but is not
required.
Most conventional thermostats, probabl including the one ou are replacing, use a single
wall mounted enclosure. The BAYweb thermostat uses two modules: the Thermostat Ke pad
and the Control Module. This design eliminates the use of batteries and potential need to pull
new wire out to the wall, and results in a more compact and elegant design.
The Thermostat Ke pad is mounted on wall in place of
our existing thermostat.
If our existing thermostat is larger than the new one,
ou can easil pull off the ke pad later to touch up the
paint after ou have completed the installation.
The control module mounts near or on our
furnace and/or air conditioner, and is spliced
into our existing thermostat wire.
The module can be powered directl from the
furnace or from an outlet ideall on the same
circuit as our furnace.
You will need an Internet connection for the
Control Module.
If it is not convenient to plug into our network
there, consider using an optional power-line
Ethernet adapter.

Your existing installation is should be
similar to this depiction.
You have a single thermostat cable
going between our wall mounted
thermostat and the furnace.
The cable contains from 2 to 5 wires of
different colors.
Your BAYweb Thermostat installation is shown below. The Control Module is mounted near
the furnace or air conditioner and is wired into the existing thermostat cable. The control
module is powered from a standard outlet.
The specific installation steps to replace our existing thermostat with the new BAYweb
Thermostat are shown in the remainder of the installation instructions. If ou are installing the
thermostat with new equipment, the process will be similar except for removal of the old
equipment.
CAUTION: Be sure to review all of the installation steps before starting our
installation.

1Identify Wiring
The objective of this step is to identif how our thermostat wiring is connected to our
furnace, air conditioner, or heat pump. This will also determine what t pe of control
scheme our s stem uses.
A) Turn off all power to our furnace, air conditioner, or heat pump.
CAUTION: Verif that all power has been turned off. Failure to turn power
off ma result in personal injur , electric shock, and equipment damage.
B) Go to our existing thermostat and remove the cover or remove it from the wall as
needed so ou can see the terminals where the wiring is attached.
C) Note what connections our s stem uses and verif that our thermostat is using the
correct terminals with the correct wire color as shown in the table below.
If our installation is using non standard wire colors, ou will have to note what color is
being used for what terminal and match our wire colors to the appropriate terminal.
Terminal unction Standard

C or X 24 VAC Common Blue or Black

D) If ou do not have a wire attached to terminal “C” or “X”, ou will need to use the
included power suppl to power the thermostat. The power suppl plugs into a
standard 120VAC outlet and to a connector on the control module.
E) The following table shows what terminals are used b the different control methods.
Determine which control method our s stem is using b matching which terminals are
connected to our wiring.
Circle the number of the s stem t pe that ou have. You will use this information when
configuring our thermostat in Step 5.
If ou have a wire connected to terminal “E”, ou have a heat pump with an emergenc
heat function. If ou do not also have a wire connected to terminal “W” ou will need to
connect the wire connected to “E” to terminal “W”.

If ou have an question on what s stem t pe ou have, contact support
(support@ba web.com) or contact our local HVAC service compan .
* NOTE: The BAYweb Thermostat requires at least 4 wires in the thermostat cable
between the Thermostat ke pad and the Control Module. If ou have a heat or cool
onl s stem that onl has 2 wires, ou will need to install new thermostat wire. It is less
desirable, but often possible to obtain satisfactor operation using 3 wires. Consult the
Frequentl Asked Questions section at www.ba web.com for more information.
** NOTE: Some heat pump installations ma use a white wire on W2 instead of W1 for
auxiliar heat. If ou have a white wire attached to terminal W2 of our thermostat it
should be connect to the W1 terminal of the BAYweb Thermostat.
