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.

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.

Thermostat Cable

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

O Reversing Valve Orange

B Reversing Valve Dark Blue

E Emergenc Heat Varies

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.
