Installation
Overview
Installing the the mostat is a elatively simple p ocess and typically takes f om 10 to 30
minutes to complete. You should conside the cu ent outdoo tempe atu e. If unexpected
p oblems occu , you do not want to isk f eezing o ove heating, while you a e so ting the
p oblem out.
You will need sc ewd ive s, a wi e st ippe /cutte , and a d ill fo installing the wall ancho s to
complete the installation. A volt/ohm mete can be helpful fo t oubleshooting but is not
equi ed.
Most conventional the mostats, p obably including the one you a e eplacing, use a single
wall mounted enclosu e. The BAYweb the mostat uses two modules: the The mostat Keypad
and the Cont ol Module. This design eliminates the use of batte ies and potential need to pull
new wi e out to the wall, and esults in a mo e compact and elegant design.
The The mostat Keypad is mounted on wall in place of
you existing the mostat.
If you existing the mostat is la ge than the new one,
you can easily pull off the keypad late to touch up the
paint afte you have completed the installation.
The cont ol module mounts nea o on you
fu nace and/o ai conditione , and is spliced
into you existing the mostat wi e.
The module should ideally be powe ed f om
an outlet on the same ci cuit as you fu nace.
You will need an Inte net connection fo the
Cont ol Module.
If it is not convenient to plug into you netwo k
the e, conside using an optional powe -line
Ethe net adapte .

You existing installation is should be
simila to this depiction.
You have a single the mostat cable
going between you wall mounted
the mostat and the fu nace.
The cable contains f om 2 to 5 wi es of
diffe ent colo s.
You BAYweb The mostat installation is shown below. The Cont ol Module is mounted nea
the fu nace o ai conditione and is wi ed into the existing the mostat cable. The cont ol
module is powe ed f om a standa d outlet.
The specific installation steps to eplace you existing the mostat with the new BAYweb
The mostat a e shown in the emainde of the installation inst uctions. If you a e installing the
the mostat with new equipment, the p ocess will be simila except fo emoval of the old
equipment.
CAUTION: Be su e to eview all of the installation steps befo e sta ting you
installation.

scheme you system uses.
A) Tu n off all powe to you fu nace, ai conditione , o heat pump.
CAUTION: Ve ify that all powe has been tu ned off. Failu e to tu n powe
off may esult in pe sonal inju y, elect ic shock, and equipment damage.
B) Go to you existing the mostat and emove the cove o emove it f om the wall as
needed so you can see the te minals whe e the wi ing is attached.
C) Note what connections you system uses and ve ify that you the mostat is using the
co ect te minals with the co ect wi e colo as shown in the table below.
If you installation is using non standa d wi e colo s, you will have to note what colo is
being used fo what te minal and match you wi e colo s to the app op iate te minal.
Note that if you have a wi e connected to te minal “C” o “X”, it will not be used fo you
BAYweb The mostat installation.

the mobile web po tal, ente the following add ess in you mobile phone b owse :
www.bayweb.com/mobile.
Occupancy Sensing
The BAYweb The mostat can use va ious types of senso s (motion senso s being the most
common) which allow the the mostat to “know” when you a e home (Occupied) o when you
a e away (Not Occupied).
Occupancy senso s enable the Web The mostat to ope ate as one of the most efficient
the mostat available today. Using occupancy senso s will save you the most amount of
money and simplify setting up you the mostat.
Using Occupancy Sensing allows you to only pay fo heating o ai conditioning to you
comfo t level when you a e the e. Imagine unning out to go shopping on a weekend and
being gone f om you house fo say 5 hou s. Do you always tu n you the mostat down when
you go shopping? Now you BAYweb The mostat can do it fo you.
Use of Occupancy Sensing simplifies setting up you the mostat’s schedule because all you
need to do is dete mine when you gene ally a e asleep and when you gene ally wake up (if
you want you house heated befo e you wake). The emainde of the time you can tell the
the mostat to sense if you a e the e o not.
While “Sensing”, the the mostat will automatically set back the tempe atu e to you “Away”
set point afte a pe iod of time of not sensing occupancy. Likewise, upon sensing occupancy,
it will switch to you “Ho e” set point.
Scheduling a “Sleep” activity disables Occupancy Sensing to p event switching to the Home
set point if you get up in the middle of the night and happen to pass a senso .
I ple enting Occupancy Sensing
To enable and use occupancy sensing you need to install one o mo e occupancy senso s
and configu e the the mostat to use them on the web po tal.
The the mostat can use wi eless (X10 wi eless p otocol) o wi ed occupancy senso s. Bay
sells a low cost wi eless occupancy senso that is eady to use with the BAYweb The mostat.
Just put in a couple of batte ies and mount it in a location that typically sees activity when you
a e home. You can use as many senso s as needed enabling the the mostat to monito
multiple locations in you home fo occupancy.
Wi ed occupancy senso s can use eithe no mally open o closed contacts. Motion senso s
f om most ala m systems a e compatible with the BAYweb the mostat.

Occupancy sensing with pets in the home is accomplished by masking off the lowe pa t of
the sensing lens.
You should locate you senso s in high-t affic a eas of you house so that they will be most
likely to sense when people a e p esent. The senso s f om Bay have a 10+ foot ange and will
sense people as they pass in f ont of the senso . We have found that locating them at about
chest height o highe wo ks well.
Once you have installed you occupancy senso s login to the web po tal to enable them. To
enable occupancy sensing select the “Schedule” page f om the the mostat applet menu and
set the “Occupancy Inactivity Time”. We suggest using 1 hou fo this inte val initially, you can
adjust this value late if needed to suit you lifestyle.
If you a e using senso s not supplied by Bay, you may need to configu e the the mostat to
look fo othe wi eless IDs o to monito the wi ed input. This is done on the “Settings” page of
the the mostat applet.
Afte enabling occupancy sensing eview you schedule and set you “Sensing”, “Sleep” , and
“Home” times as desc ibed above. You the mostat will now automatically adapt you HVAC
ope ation to match you lifestyle.
Testing Occupancy Sensing
If you want to see if the senso s a e wo king as expected, login to the web po tal and select
“Senso Log” f om the the mostat applet menu.
The the mostat applet “Ope ation Log” will give a detailed view of occupancy sensing
ope ation.
Occupancy Sensing with Multiple Ther ostats
If you a e using multiple BAYweb the mostats in the same building, and wish to have each
the mostat sense occupancy (using wi eless senso s) in sepa ate a eas, you will need to
configu e the occupancy senso s with diffe ent X10 device IDs.
The default X10 ID of Bay supplied senso s is “A1”. Note that these senso s also use an ID
that is one mo e than what is configu ed (default “A2”) fo othe pu poses, do not use the next
ID fo occupancy sensing. Fo example, acceptable IDs would be A1, A3, A5...
Refe to the inst uctions p ovided with the senso fo detail on how to change the senso 's
X10 ID. Configu e the the mostat to look fo the alte nate X10 IDs on the “Settings” page of
the the mostat applet.
