Thermostats & Controls FAQ

Like many smart thermostats on the market, our BCC family of connected thermostats require a 24vdc 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.

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.

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!

1. Pull the thermostat away from its wall plate.

2. Look at the rear of the thermostat. You will see a standard microUSB socket.

3. Plug a suitable working charger/power adaptor into that socket.

4. If the thermostat's display now turns on, the problem is likely to be in the installation wiring and not the product itself.

5. To resolve the problem, we recommend that you work with an electrician to investigate and rectify the power supply or wiring issue.

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.

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:

a. Use your cellphone to create a Wifi hotspot.

b. While standing close to your thermostat, attempt to connect it to the hotspot instead of your router.

2. Or you can remove the thermostat from its wall mount bracket.

a. Look at the rear of the thermostat and will notice a microUSB socket.

b. 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 or boiler.techsupport@us.bosch.com for further assistance.

The thermostat is compatible with 2.4Ghz Wifi systems only, and will not work with 5Ghz systems or web pages that require additional web authentication.

No, only one account can be associated to any given thermostat.

If you would like additional family members to have control of the thermostat via their mobile devices, you will need to share the account information with them.

No, multi-zone systems are not supported.

The password can be reset via the mobile app, or by physically removing the thermostat from the wall plate, waiting for a few seconds, and then replacing it back onto the plate.

Yes, they can indeed!

Detailed instructions on how to set up the account connections, and example voice commands, can be found in the product manuals, which can be downloaded from this web page

The most common two causes of this error, and their fixes, are;

1. The thermostat’s firmware is out of date.

To update the firmware, please do the following;

a. Ensure that the thermostat is connected to a Wifi network.

b. Tap the three-bars symbol in the top-left corner of the screen to bring up the Menu.

c. Tap, “System Settings”.

d. Tap “System Update”, and follow the instructions to download and install the latest firmware version.

2. If updating to the latest firmware version did not resolve the “Verification Code Error”, then it’s possible that the thermostat’s IP address is set incorrectly.

To check the IP address, please do the following;

a. Tap the three-bars symbol in the top-left corner of the screen to bring up the Menu.

b. Tap “Advanced Settings”.

c. Tap “Installer Access”.

d. Enter the code “1886” and hit “OK”.

e. Now enter “IP” and hit “OK”.

f. The “CURRENT IP:COM” should be showing as; 13.52.165.131:80.

g. If a different IP address is shown, use the keypad to enter 13.52.165.131:80 and hit “OK”.

3. If the firmware has been updated to the latest version and the IP address is correct but you are still getting the “Verification Code Error”, please contact our support team on 1-800 283 3787 Monday to Friday for further assistance.

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.

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.

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.

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

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.

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.

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.
