Thermostat Installation
Step 1
Turn OFF power
Turn off all power to your HVAC (Heating, Ventilation, and Air Conditioning) system by using the master equipment switch or circuit breaker box.

ON

OFF

WARNING: Failure to turn off the power may result in electrical shock and/or damage to the equipment.
Confirm that your system is off
One way to do this is to try to adjust the temperature on your old thermostat. If you don’t hear the system turn on within 5 minutes, air does not come out from the vents or the old thermostat does not even power on, then you have successfully turned off the power to your system.

Step 2
Remove the old thermostat from the old wall plate

Step 3
Make sure your old thermostat Does Not Contain Line Voltage Wiring
If you see any of these wire nuts, unfortunately the BCC110 may not work with your system. If you are unsure or would like to discuss your options, please contact a professional or our support line: 1- 8 0 0 -28 3 – 3787.

Step 4

Take a picture of the existing wiring
Make sure that you can clearly read the terminal labels and see which wires are connected to which terminals from your photo. You will need to reference this photo later during the initial setup.

Note: You can also use the wire labels we have provided you to correctly label each wire based on the terminal where it is connected.

Step 6
Disconnect the wires from the old thermostat and remove the wall plate using a screwdriver
Some thermostats will also require you to use a screwdriver to disconnect the wires. After the wires are disconnected and the wall plate removed, we recommend wrapping a pen or pencil around the wires to prevent them from falling back into the wall.

Step 5
Confirm you have a C-wire connected to your old thermostat wall plate
If you do not have a C-wire connected to your old thermostat, please contact a professional or our support line for further assistance to determine if the BCC110 Thermostat is compatible with your system.

Step 7

Pull thermostat wires through the hole in the center of the BCC110 wall plate and mark the location of the mounting screws

It is recommended to use the BCC110 Wall Plate as a reference guide

to mark the mounting holes and ensure that all holes

and

unpainted surfaces are

covered.

Step 8
Drill and insert wall anchors (if necessary)
Drill two 7/32″ holes where you marked the location of the mounting screws and then insert the wall anchors provided into these mounting holes.
Check if the wall plate is level and insert screws
Make sure your new BCC110 wall plate is level and insert the included screws from the package. Mount your new wall plate to the wall using a Phillips head screw driver.
LEVEL

Step 9
Insert each wire into the corresponding terminal and close each terminal using a flat head screw driver
Use the image you took with your smartphone of your old thermostat wiring or the wire labels as a reference for where to place each wire. Be sure that you insert each wire, one by one, and then immediately close the terminal and confirm that the wire is secure inside the terminal before moving to the next wire. Repeat this process for each wire to be installed. If you are unsure of the terminal names on the BCC110 Wall Plate, refer to BCC110 Terminal Key on the next page.

Troubleshooting & Frequently Asked Questions

Wi-Fi Can the BCC110 be used without Wi-Fi?
We strongly encourage everyone to use the Wi-Fi capabilities of the thermostat, as it will improve the user experience. However, it is functional without the use of Wi-Fi after the Initial Setup has been completed. NOTE: The Dual Fuel feature is disabled when Wi-Fi is unavailable. Dual fuel requires Wi-Fi to determine outdoor air temperature and function properly.
Will the BCC110 support all Wi-Fi systems & routers? This device only works with 2.4 GHz systems and is NOT compatible with 5.0 GHz systems or web pages that require additional web authentication.
Trouble Connecting to your Home’s Wi-Fi Network? 1. Make sure that your thermostat is a maximum 20 ft or less from the router/modem without any obstructions (i.e. walls, floors, ceilings, etc.). If obstructions exist, try moving your thermostat and router/modem closer together. 2. Before attempting to reconnect your thermostat to your home network, power cycle your router/modem and then your thermostat. If you have a separate router and modem, make sure that you power cycle the modem first and then the router. 3. In the event that you still cannot connect to your home’s wi-fi network please contact our support team for further in-depth technical troubleshooting options. NOTE: If you are able to connect to your home network, but the time does not update on the thermostat, you are not fully connected to the cloud server. Please follow the troubleshooting steps again or contact Bosch Technical Support.

Troubleshooting & Frequently Asked Questions
Bosch EasyAir App (Android and iOS) What is the name of the smartphone app in the App Store and Google Play Store?
The name of the app is Bosch EasyAir App. How many accounts can be associated with the thermostat at once? Only one account can be associated with a given thermostat. Family members must share their account information with each other if they would like to be able to control the thermostat from multiple devices. Can this device be accessed via a web page? Not at this time.
Thermostat What happens if I lose power to the device; will all my settings be lost?
All settings are kept in local memory, except for the schedule setpoints, which are stored in the cloud. Therefore, all settings will be saved even during a power outage.

Thermostat Overview
Humidifier & Dehumidifier Operating Mode
You can enable automatic humidity control if the correct humidifier or dehumidifier accessory was correctly wired and configured during the thermostat’s initial setup. Based on the setup, the thermostat turns on the humidifier during heating operation and the dehumidifier will be turned on during cooling operation. You can also configure the thermostat to operate similar to a humidistat, which runs the humidifier or dehumidifier, regardless of an active heating/cooling call.

Temperature, Alerts, and Auto-On Alert: Send an alert message or turn on the system
automatically when the room temperature is out of the range between set- points.
Note: Alerts are an additional source of protection for your heating/cooling appliance.

Note: You may only operate in either humidifier OR dehumidifier mode and may not operate in both modes at the same time.

Run Time
The thermostat keeps track of your run time for the Heating, Cooling, Air Filter and Water Pad. You can also set a reminder for Air Filter and Water Pad according to the number of calendar days. When it reaches its predefined run time, the thermostat displays a notification and sends a message to the registered smart device(s).
