Introduction Thank you for purchasing the BAYweb Thermostat. You now have one of the most advanced Heating, Ventilating, and Air Conditioning (HVAC) control systems available today. This thermostat is easily installed by home owners or HVAC professionals. It can be used to replace an existing thermostat or for installation with new heating or cooling equipment.
Bay Controls, LLC. expressly disclaims responsibility or liability for any injury or damage caused by failure to observe specified or other common safety precautions or failure to exercise ordinary caution, common sense, and due care required in installing and operating the thermostat even though not specified herein. The alert message shown here appears throughout this manual to indicate those situations and times when special care is necessary to prevent equipment damage or personal injury.
Limited Warranty Subject to the limitations contained below, and except as otherwise expressly provided herein, Seller warrants to the Buyer that all tangible articles supplied by Seller or services provided by Seller will be free of defects in materials or workmanship under normal use and care until the expiration of the applicable warranty period. Goods are warranted for five (5) years from the date of purchase.
Installation Overview Installing the thermostat is a relatively simple process and typically takes from 10 to 30 minutes to complete. You should consider the current outdoor temperature. If unexpected problems occur, you do not want to risk freezing or over-heating someone or something while you are sorting the problem out. You will need screwdrivers, a wire stripper/cutter, and a drill for installing the wall anchors to complete the installation.
Your existing installation is should be similar to this depiction. Thermostat Cable You have a single thermostat cable going between your 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.
1 Identify Wiring The objective of this step is to identify how your thermostat wiring is connected to your furnace or air conditioner, and to confirm that you have the correct model of the BAYweb Thermostat for your equipment. A) Turn off all power to your furnace and air conditioner. ! CAUTION: Verify that all power has been turned off. Failure to turn power off may result in personal injury, electric shock, and equipment damage.
2 Install Control Module A) Find your thermostat cable where it goes into the furnace or air conditioner. This is the same cable identified in Step 1 and should be the same color and thickness as that cable. ! CAUTION: There may be other cables of similar color connecting other devices such as a humidifier. Be sure to use the cable that runs back to your thermostat and not one that is connected to another device.
D) Confirm that the terminal screws are tight, the wires will not pull out of the terminals, and that there are not any shorts between terminals. ! CAUTION: It is very important to connect the thermostat cable to the correct connectors on the Control Module. If you connect the control module “Thermostat” connector to your furnace or air conditioner wiring, the control module will be damaged.
3 Install Thermostat Keypad A) Remove the wires from your existing thermostat, taking care that the wires do not fall back into the wall. B) Remove the existing thermostat and any associated mounting hardware. C) Fill in any holes from the previous thermostat mounting and paint the wall if needed. D) Hold the Thermostat Keypad in the desired position and mark the location of the mounting screws. Drill 3/16 inch holes and install the supplied wall anchors.
4 Connect to the Internet Now that you have the thermostat in and working, it is time to connect it to the Internet to enable it's advanced capabilities. A) Connect the Control Module to the Internet. Plug one end of an Ethernet cable into the LAN port on the bottom of the Control Module and the other end into a port on a router or switch on your home network. B) If direct wiring is not convenient, use power line Ethernet adapters.
5 Test Operation A) Plug the Control Module into the power outlet. B) Turn the power back on to the furnace/air conditioner. C) Verify that the “Power” and “Thermostat” lights are illuminated on the control module. If either one is not on, refer to the Troubleshooting section of this manual. D) Verify that the Thermostat Keypad is showing the temperature. If it is showing an “E” with a number, this is an error code. Refer to the Troubleshooting section.
Operation Using the Thermostat Keypad The Thermostat Keypad shows the current temperature, set point and modes, and allows you to manually control your furnace and air conditioner. Indicators show which modes are selected Press to select HEAT mode. If selected, press again to turn OFF. Press to select COOL mode. If selected, press again to turn OFF. Press once to show the current set point. Press again to change. Current Temperature Press to change HOLD mode.
Using Your Mobile Phone Once you have setup your your account on the web site, you can also use most any mobile phone that has web access to remotely access your thermostat and other web devices. To access the mobile web site, enter the following address in your mobile phone browser: www.bayweb.com/mobile. There is a BAYweb mobile App available for many phones. Search for “bayweb” in the App store or Market for your mobile device.
Occupancy sensing with pets in the home is accomplished by masking off the lower part of the sensing lens. You should locate your sensors in high-traffic areas of your house so that they will be most likely to sense when people are present. The sensors from Bay have a 10 foot+ range and will sense people as they pass in front of the sensor. We have found that locating them at about chest height or higher works well. Once you have installed your occupancy sensors login to the web site to enable them.
• Loss of Internet connectivity. • Other problems or alerts with anything else you choose to connect to the control module (wired or wireless). Alerting provides many of the features of a traditional alarm system without the monthly fee. If you have an alarm system that is no longer in use, you can wire those sensors into the control module to convert your old system to a self-monitored system.
Reference Thermostat Keypad The Thermostat Keypad module senses the current temperature and provides an interface for manual control. Normally the displayed number (68 in this case) indicates the current temperature. To change the set point, press the up or down arrows. The display will switch to the current set point. Note that a decimal point is displayed while showing the set point. The display will automatically revert to the current temperature after a few seconds if no keys are pressed.
Code Meaning E1 Indicates that the thermostat keypad is not communicating with the control module.
! CAUTION: Do not connect the Alert input to any external voltage source. Dry contacts only. Failure to do so may cause equipment damage. Thermostat Connector This connector is used to connect the Thermostat Keypad module to the Control Module. This is a proprietary interface and can only be used with the specified modules. The Red and White terminals supply power (3.3 VDC), the Green and Yellow terminals utilize a proprietary communications protocol.
Thermostat Indicates that the control module is successfully communicating with the Thermostat Keypad module. Uplink Indicates that the control module is online with the BAYweb servers. Troubleshooting We encourage you to communicate any problems you have encountered to us, even if you are able to solve them on your own.
