Thermostats & Controls FAQ

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.

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.

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.

Password for Advanced Settings is 1886.

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.
