We have created an "BCC110 Advanced Settings Guide", and you can download it from this page.

Once you've finished installing the BCC110 thermostat and have set it up for your particular heating/cooling equipment and application, you can now choose to connect it to your WiFi network*.

The method to do so will depend on whether you have a "normal" WiFi network that broadcasts its name (SSID) and can be seen by your devices, or a "Hidden" WiFi network that cannot be seen by devices and requires the user to manually enter the network name;

"Normal" WiFi Network

1. The WiFi connection process is automated, and you can initiate it by clicking on the WiFi icon in the top-right corner of the screen and then clicking the Scan icon.
2. Follow the on-screen prompts to select your WiFi network from the list and continue through the setup to completion.

"Hidden" WiFi Network

1. To connect to a hidden WiFi network you will need to manually enter the details. Begin by clicking on the WiFi icon in the top-right corner of the screen and then clicking "SSID".
2. Enter the name of your WiFi network into the text box, then follow the on-screen prompts to complete the WiFi setup.

*The BCC110 thermostat will still control your heating and cooling equipment even if it is not connected to a WiFi network, and its touch screen interface and various settings will still allow you to be able to make changes.

Being connected to WiFi though will allow you to use your mobile devices to connect to the thermostat remotely via the EasyAir app (requires registration), and also be able to remove live weather update information.

The most likely reason for the display not turning on is that there is no power (or insufficient power) running to the thermostat. It's easy to assume that the installer has wired the product correctly, but simple mistakes can happen. In addition, you could even find that the installation wiring itself is physically defective (such as a broken conductor).

Fortunately, there is an easy way to test this and it only requires a microUSB phone charger!

• Pull the thermostat away from its wall plate.
• Look at the rear of the thermostat, you will see a standard microUSB socket.
• Plug a suitable working charger/power adaptor into that socket.
• If the thermostat's display now turns on, the problem is likely to be in the installation wiring and not the product itself.
• To resolve the problem, we recommend that you work with an electrician to investigate and rectify the power supply or wiring issue.

Like many smart thermostats on the market, our BCC family of connected thermostats require a 24VAC power supply to operate. This requires that the wiring that connects the BCC thermostat to your heating/cooling equipment has a C-wire (or "common" wire).

While the name "common" implies that you will see a C-wire frequently, you may find that your wiring may not have the required conductor, and this can be especially true in older homes or older HVAC installations.

If you are unsure if you have a C-wire, we recommend that you contact a qualified HVAC professional to inspect your installation. To search for a contractor in your area, please visit this webpage.

In the event that your existing wiring does not have a C-wire, and if you are unable to have updated wiring run in place of the existing wiring, we have provided an alternative method to provide power to the thermostat.

If the look at the rear of the thermostat you will see a microUSB socket. Your contractor may use a microUSB power adaptor to provide power to the thermostat and then use your existing thermostat wiring to connect the property's HVAC equipment to the relevant controls terminals on the thermostat.

For more installation and operations information, the product manuals can be downloaded from this webpage.

In dual fuel systems, the thermostat switches between heat pump and furnace operation to optimize comfort & efficiency.

In firmware versions 2.0.0 & prior, overshooting may occur in certain cases as the thermostat delays switching the system off when the setpoint is reached until the stage delay timer expires.

Reducing the stage delay timer to 5 minutes can help resolve this issue.

Below are step-by-step instructions to adjust the stage delay timer:

1. Press the Main Menu button on the thermostat
2. Enter Advanced Settings
3. Choose Installer Access
4. Enter the Access Code “1886” to access the installer settings
5. Input the Action Code Enter the action code “ST”
6. Adjust the Stage Delay Timer
7. Reduce the delay timer to 5 minutes.

There can be the potential for a "Critical High Pressure" alert to be displayed on the screen of the thermostat when it is used to control a Bosch IDS heat pump system.

There is no cause for concern. The issue has been found to be caused by a communication misunderstanding between the heat pump and the thermostat, and the result is that the warning displays itself on the thermostat screen despite there being no failure event.

Functionality of the system is not impacted at all, and you can simply click "Ok" on the screen to close the alert.

First, ensure that your WiFi network is 2.4Ghz and not 5Ghz. BCC110 thermostats are not compatible with 5Ghz WiFi routers and networks.

If you are using a 2.4Ghz WiFi network but are experiencing connectivity issues, please follow the guidance below to rule out a WiFi range issue.

WiFi range can be reduced by obstacles in the property, such as walls, floors and furniture.

To test to see if your thermostat is experiencing a poor WiFi signal from your router, please do either of the two following tests:

1. Cellphone Hotspot:

• Use your cellphone to create a WiFi hotspot.
• While standing close to your thermostat, attempt to connect it to the hotspot instead of your router.

• Look at the rear of the thermostat and will notice a microUSB socket.
• Plug a microUSB charger into that socket and use it to power up the thermostat next to the property's WiFi router.

If you experience good WiFi connection on the thermostat with it powered up next to the router, or via your cellphone hotspot, then this may indicate that its wall mounted location is too far from the router. This may be especially true if obstacles are present between the router and the thermostats wall mount location. Consider relocating the thermostat to be closer to the router.

If you still experience WiFi problems with the thermostat powered up next the router or via your cellphone hotspot, and no other WiFi devices are having connection issues, then this may indicate a technical problem with the thermostat itself. Please contact our technical team at 1-800 283 3787.

The basic Logamatic 2107 control comes from the factory with the ability to control single stage burners only.

If a 2 stage burner or a modulating burner is to be installed on the boiler, then a Buderus FM242 card must be purchased and installed into the 2107.

The "FM 242 ERROR" can appear on the screen of the Logamatic 2107 control under the following conditions:

• If you are using a single stage burner and do not have an FM242 card installed in your Logamatic 2107, then this error indicates that the control is incorrectly set to "2-STAGE" instead of the correct setting of "1-STAGE".
  
  To remedy this, please refer to the "Setting The Burner Type" section of the installation and service manual and set the burner type to "1-STAGE".

• If you do have an FM242 card installed in the 2107 to control a 2-stage burner, then this error message could be an indication of a loose connection or a problem with the card itself.
  
  To check this, turn the power to the boiler and 2107 off, remove the cover from the 2107, gently remove the FM 242 card, reinsert it back into the slot, replace the cover and turn the power back on.
  
  If the "FM 242 ERROR" message has not reappeared then the issue is resolved.
  
  If the error message is still displayed though, this may indicate that the FM242 card has failed and needs to be replaced.

If you no longer have a copy of the installation and service manual for your Logamatic 2107, you can download a digital copy from this page.

Outdoor Reset is a boiler control method that uses a remote sensor to read what the temperature is outdoors, and then adjusts the boiler's high limit temperature setting accordingly.

So instead of having a fixed high limit boiler temperature (180of for example) that remains constant regardless of what the outdoor temperature is, we instead have a boiler temperature that can raise up and down in relation to the outdoor temperature.

The primary benefit of this is fuel economy - If the boiler can satisfy the heat demands of the property at a lower high limit temperature (due to it being warmer outside, for example), then less fuel is required.

An additional benefit is comfort - Outdoor Reset allows the boiler's heat output to automatically be better matched to the heat loss of the property, which reduces temperature fluctuation in the room.

For further details, several Logamatic R2107 manuals are available on this page

WWSD is "Warm Weather Shut Down".

This is a setting that will automatically shut down the space heating function of the system if the outdoor temperature rises above a preset point. You can set that preset to be any temperature between 49°f (9°c) and 87°f (31°c).

Example; If you have WWSD set to 65°f, the space heating function of your system will be shut off when the outdoor temperature exceeds 65°f.

Please note that it is ONLY space heating that is shut down by WWSD, domestic hot water production (if used) will continue to operate as normal.

For further details and instructions on how to change the WWSD setting, or to turn it off completely, several Logamatic R2107 manuals are available on this page

If you select "English" as the language setting, your control will display English text with temperature readings in Celsius.

If you select "American" as the language setting, your control will display English text with temperature readings in Fahrenheit.

Directions on how to change the language setting can be viewed in the video below.

It's likely that you have the language set to "English" in the control.

Change it to "American" and the temperature will now be displayed in Fahrenheit.

Directions on how to change the language setting can be viewed in the video below.

To update the time in the control, please follow the directions in the video below.

Yes, you can indeed turn off DHW production and have the control focus on space heating only.

For further details and instructions on how to change the DHW production setting, several Logamatic R2107 manuals are available on this page

The heating curve is a programming setting that automatically controls the relationship between the outdoor temperature and the amount of heat energy that the boiler is putting into the heating circuit's water.

Example; When it's warmer outside, a lower heating circuit supply water temperature will be needed to satisfy the zone's desired temperature. When it's colder outside, a higher heating circuit supply water temperature will be needed to satisfy the desired temperature.

For further details and instructions on how to change the heating curve setting (if needed), several Logamatic R2107 manuals are available on this page

To optimize fuel economy, the 2107 will automatically switch between a Day mode and a Night mode based on the schedule that is programmed in by the installer or the user.

In Day mode, the control is set to take care of space heating and the production of domestic hot water.

In Night mode, the production of domestic hot water is turned off to save energy. The logic behind this is that the average household is not looking at using much hot water during typical sleep hours.

To accommodate your DHW needs, either the Night hours can be adjusted or you can even set the control to produce domestic hot water on a 24 hour basis with it never being shut off.

For further details and instructions on how to change the DHW settings, several Logamatic R2107 manuals are available on this page

Most commonly it's as simple as the price of fuel from your supplier has increased. If this is the case, you may be paying a similar total dollar amount to what you paid previously but you've actually used less fuel. So when comparing dollar amounts, it's always crucial to factor in the price per gallon value.

Additionally it's important that the R2107 has been programmed correctly to match the needs of the property efficiently.

We recommend that a heating contractor assess the heating needs of the home and then ensure that the control's settings were programmed correctly by the installer.

To help the contractor with this task, several Logamatic R2107 manuals are available on this page
