Introduction
T ank you for purc asing t e BAYweb T ermostat. You now ave one of t e most advanced
Heating, Ventilating, and Air Conditioning (HVAC) control systems available today.
T is t ermostat is easily installed by ome owners or HVAC professionals. It can be used to
replace an existing t ermostat or for installation wit new eating or cooling equipment.
T is model of t e BAYweb T ermostat (BW-WT1) is designed for use wit eating and
cooling equipment t at utilize single stage control, w ic is t e most common.
Multistage furnaces are often controlled using single stage t ermostats, andling t e second
stage control internally. If your t ermostat uses 5 wires or less, it is likely using single stage
control. Step 1 of t e installation will verify t at you are using t e correct model of t ermostat
for your equipment.

Installation
Overview
Installing t e t ermostat is a relatively simple process and typically takes from 10 to 30
minutes to complete. You s ould consider t e current outdoor temperature. If unexpected
problems occur, you do not want to risk freezing or cooking someone or somet ing w ile you
are sorting t e problem out.
You will need screwdrivers, a wire stripper/cutter, and a drill for installing t e wall anc ors to
complete t e installation. A volt/o m meter can be elpful for troubles ooting but not required.
Most conventional t ermostats, probably including t e one you are replacing, use a single
wall mounted enclosure. T e BAYweb t ermostat uses two modules: t e T ermostat Keypad
and t e Control Module. T is design eliminates t e use of batteries and potential need to pull
new wire out to t e wall, and results in a more compact and elegant design.
T e T ermostat Keypad is mounted on wall in place of
your existing t ermostat.
If your existing t ermostat is larger t an t e new one,
you can easily pull off t e keypad later to touc up t e
paint after you ave completed t e installation.
T e control module mounts near or on your
furnace and/or air conditioner, and is spliced
into your existing t ermostat wire.
T e module can be powered directly from t e
furnace or from an outlet ideally on t e same
circuit as your furnace.
You will need an Internet connection for t e
Control Module.
If it is not convenient to plug into your network
t ere, consider using an optional power-line
Et ernet adapter.
4

Your existing installation is s ould be
similar to t is depiction.
You ave a single t ermostat cable
going between your wall mounted
t ermostat and t e furnace.
T e cable contains from 2 to 5 wires of
different colors.
Your BAYweb T ermostat installation is s own below. T e Control Module is mounted near
t e furnace or air conditioner and is wired into t e existing t ermostat cable. T e control
module is powered from a standard outlet.
T e specific installation steps to replace your existing t ermostat wit t e new BAYweb
T ermostat are s own in t e remainder of t e installation instructions. If you are installing t e
t ermostat wit new equipment, t e process will be similar except for removal of t e old
equipment.
CAUTION: Be sure to review all of t e installation steps before starting your
installation.

1Identify Wiring
T e objective of t is step is to identify ow your t ermostat wiring is connected to your
furnace or air conditioner, and to confirm t at you ave t e correct model of t e BAYweb
T ermostat for your equipment.
A) Turn off all power to your furnace and air conditioner.
CAUTION: Verify t at all power as been turned off. Failure to turn power
off may result in personal injury, electric s ock, and equipment damage.
B) Go to your existing t ermostat and remove t e cover or remove it from t e wall as
needed so you can see t e terminals w ere t e wiring is attac ed.
C) Verify t at your t ermostat is using t e correct terminals wit t e correct wire color as
s own in t e table below. If your installation is using non standard wire colors, you will
ave to note w at color is being used for w at terminal and matc your wire colors to
t e appropriate terminal.
Terminal Function tandard Wire Color My Wire Color
R 24 VAC Supply for eat/cool Red
R 24 VAC Supply for eat Red
Rc 24 VAC Supply for cool Red
W or W1 Heat W ite
G Fan Green
Y or Y1 Cool Yellow
C or X 24 VAC Common Blue or Black
D) If you do not ave a wire attac ed to terminal “C” or “X”, you will need to use t e
included power supply to power t e t ermostat. T e power supply plugs into a
standard 120VAC outlet and to a connector on t e control module.
E) If you ave more t an 5 wires connected to terminals not s own in t e table above,
t is model of t ermostat is probably not compatible wit your equipment. You will need
t e advanced model BAYweb T ermostat, part number BW-WT2. Refer t e
T ermostat Connections section of t is manual and www.bayweb.com for more
information.
NOTE: T e BAYweb T ermostat normally requires at least 4 wires in t e t ermostat cable
between t e T ermostat keypad and t e Control Module. If you ave a eat or cool only
system t at only as 2 wires, you will need to install new t ermostat wire.

2Install ontrol Module
A) Find your t ermostat cable w ere it goes into t e furnace or air conditioner. T is is t e
same cable identified in Step 1 and s ould be t e same color and t ickness as t at
cable.
CAUTION: T ere may be ot er cables of similar color connecting ot er
devices suc as a umidifier. Be sure to use t e cable t at runs back to your
t ermostat and not one t at is connected to anot er device. Connecting t e
Web T ermostat to t e wrong cable can result in electric s ock and/or
equipment damage.
B) Mount t e Control Module using t e following criteria:
◦Select a location near t e furnace w ere t ere is sufficient room to mount t e
Control Module along w ere t e t ermostat cable runs. T e t ermostat cable will
need to reac bot t e “T ermostat” and “Furnace/AC” terminals of t e Control
Module.
◦If you will be using t e included power supply (see Step 1D), select a location wit in
4 feet of a power outlet, ideally on t e same circuit as t e furnace/AC.
◦Select a location w ere you can connect to t e Internet. If wiring is not convenient,
we suggest using a power line Et ernet adapter t at will allow you to make t is
connection using your existing power wiring.
C) Splice t e Control Module into your existing t ermostat cable:
Wit t e furnace and air conditioner power OFF, cut t e t ermostat wire at a point
w ere bot ends will be able to reac t e Control Module mounting location.
Using a wire-stripping tool, strip approximately 2 inc es of t e outer jacket off bot
ends of t e t ermostat cable, t en strip approximately ¼ inc off t e end of eac of t e
t ermostat wires.
Attac t e wires in t e cable coming from t e t ermostat to t e terminals on t e LEFT
side of t e control module into t e connector labeled "Thermostat". Be sure to matc
t e wire color and terminal designation as identified in Step 1.
Attac t e wires in t e cable coming from t e furnace to t e terminals on t e RIGHT
side of t e control module labeled "Furnace/AC". Be sure to matc t e wire color and
terminal designation as identified in Step 1.
NOTE: If your system uses separate R and Rc wires, be sure to remove t e jumper
wire between t e R and Rc terminals. If your system uses a single Red wire, make
sure t e jumper wire between terminals R and Rc is installed.

D) Confirm t at t e terminal screws are tig t, t e wires will not pull out of t e terminals,
and t at t ere are not any s orts between terminals.
CAUTION: It is very important to connect t e t ermostat cable to t e correct
connectors on t e Control Module.
If you connect the control module “Thermostat” connector to your
furnace or air conditioner wiring, the control module will be damaged.
8
!

T e Control Module is mounted near t e
furnace w ere t e t ermostat cable is routed.
You will connect t e module to your network
using standard Et ernet cable, or using t e
power line Et ernet adapters.
Orient t e Control Module so t e Furnace/AC
connector is on t e side t at goes to t e
furnace, mounting it “upside down” if needed.
Prepare t e t ermostat cable for connection
to t e Control Module as s own.
Strip about 2 inc es of t e cable jacket off of
eac end. Make sure you do not cut t e
insulation on t e inner wires.
Strip about ¼ inc of insulation from bot
ends of eac wire as s own.

wit t e screwdriver andle to insure t at are flus or slig tly indented into t e wall.
E) Screw t e supplied mounting screws into t e wall anc ors leaving about 1/16t inc
gap for t e T ermostat Keypad to slide over.
F) Make sure t e ends of eac wire are stripped and ready to be attac ed to t e new
T ermostat Keypad. If any wires break off t en use your wire stripper to strip
approximately ¼ inc of insulation from t e end of t e wire.
G) Using t e supplied wire nuts, attac t e four colored wires coming from t e T ermostat
Keypad (red, w ite, green, yellow) to t e four matc ing colored wires from t e cable in
t e wall. If your installation uses non standard wire colors, use t e table you completed
in step 1C to connect your wire colors to t e standard color of t e T ermostat Keypad.
H) If you ave any spare wires not being used, cut off any bare sections and insure t at
t ey will not s ort to anyt ing in t e T ermostat Keypad.
I) Pus t e t ermostat cable into t e wall to remove as muc slack as possible. Fit t e
any excess wiring into t e space be ind t e T ermostat Keypad.
J) Attac t e T ermostat Keypad to t e wall by sliding t e slot at t e top and key opening

Using the Web Portal
T e real power of t e BAYweb T ermostat is realized by using t e BAYweb Portal to access
your t ermostat. T is portal can be accessed anytime from anyw ere via web browser and
Internet enabled mobile p one. Unlimited use of t e portal is included at no c arge.
To setup your personalized portal go to t e web site (www.bayweb.com), register a new
account, login and add a device (your t ermostat). You will need t e serial number and key
code t at are on t e front of t is manual.
Using Your Mobile Phone
Once you ave setup your personalized web portal, you can also use most any mobile p one
t at as web access to remotely access your t ermostat and ot er web devices. To access
t e mobile web portal, enter t e following address in your mobile p one browser:
www.bayweb.com/mobile.
Occupancy Sensing
T e BAYweb T ermostat can use various types of sensors (motion sensors being t e most
common) w ic allow t e t ermostat to “know” w en you are ome (Occupied) or w en you
are away (Not Occupied).
Occupancy sensors enable t e Web T ermostat to operate as one of t e most efficient
t ermostat available today. Using occupancy sensors will save you t e most amount of
money and simplify setting up your t ermostat.
Using Occupancy Sensing allows you to only pay for eating or air conditioning to your
comfort level w en you are t ere. Imagine running out to go s opping on a weekend and
being gone from your ouse for say 5 ours. Do you always turn your t ermostat down w en
you go s opping? Now your BAYweb T ermostat can do it for you.
Use of Occupancy Sensing simplifies setting up your t ermostat’s sc edule because all you
need to do is determine w en you generally are asleep and w en you generally wake up (if
you want your ouse eated before you wake). T e remainder of t e time you can tell t e
t ermostat to sense if you are t ere or not.
W ile “ ensing”, t e t ermostat will automatically set back t e temperature to your “Away”
set point after a period of time of not sensing occupancy. Likewise, upon sensing occupancy,
it will switc to your “Home” set point.
Sc eduling a “ leep” activity disables Occupancy Sensing to prevent switc ing to t e Home
set point if you get up in t e middle of t e nig t and appen to pass a sensor.
Implementing Occupancy ensing
To enable and use occupancy sensing you need to install one or more occupancy sensors
and configure t e t ermostat to use t em on t e web portal.
15

T e t ermostat can use wireless (X10 wireless protocol) or wired occupancy sensors. Bay
sells a low cost wireless occupancy sensor t at is ready to use wit t e BAYweb T ermostat.
Just put in a couple of batteries and mount it in a location t at typically sees activity w en you
are ome. You can use as many sensors as needed enabling t e t ermostat to monitor
multiple locations in your ome for occupancy.
Wired occupancy sensors can use eit er normally open or closed contacts. Motion sensors
from most alarm systems are compatible wit t e BAYweb t ermostat.
Occupancy sensing wit pets in t e ome is accomplis ed by masking off t e lower part of
t e sensing lens.
You s ould locate your sensors in ig -traffic areas of your ouse so t at t ey will be most
likely to sense w en people are present. T e sensors from Bay ave a 10+ foot range and will
sense people as t ey pass in front of t e sensor. We ave found t at locating t em at about
c est eig t or ig er works well.
Once you ave installed your occupancy sensors login to t e web portal to enable t em. To
enable occupancy sensing select t e “Sc edule” page from t e t ermostat applet menu and
set t e “Occupancy Inactivity Time”. We suggest using 1 our for t is interval initially, you can
adjust t is value later if needed to suit your lifestyle.
If you are using sensors not supplied by Bay, you may need to configure t e t ermostat to
look for ot er wireless IDs or to monitor t e wired input. T is is done on t e “Settings” page of
t e t ermostat applet.
After enabling occupancy sensing review your sc edule and set your “Sensing”, “Sleep” , and
“Home” times as described above. Your t ermostat will now automatically adapt your HVAC
operation to matc your lifestyle.
Testing Occupancy ensing
If you want to see if t e sensors are working as expected, login to t e web portal and select
“Sensor Log” from t e t ermostat applet menu.
T e t ermostat applet “Operation Log” will give a detailed view of occupancy sensing
operation.
Occupancy ensing with Multiple Thermostats
If you are using multiple BAYweb t ermostats in t e same building, and wis to ave eac
t ermostat sense occupancy (using wireless sensors) in separate areas, you will need to
configure t e occupancy sensors wit different X10 device IDs.
T e default X10 ID of Bay supplied sensors is “A1”. Note t at t ese sensors also use ID “A2”
for internal purposes, do not use ID “A2” for occupancy sensing. Refer to t e instructions
provided wit t e sensor for detail on ow to c ange t e sensor's X10 ID. Configure t e
t ermostat to look for t e alternate X10 IDs on t e “Settings” page of t e t ermostat applet.
