For issues with your Bosch Connected Control thermostat, try performing DIY troubleshooting steps before contacting the manufacturer or service. A number of problems with the BCC thermostat can easily be resolved by simple troubleshooting techniques. Follow the instructions given in this guide to resolve some of the common issues with these thermostats.
Bosch Thermostat Won’t Connect to WIFI
The following issues may cause a failed connection to your Bosch thermostat:
Wi-Fi signal is too weakIncorrect password5GHz Wi-Fi network is not supportedAdditional web authentication is not supportedSSID contains space or non-ASCII charactersWi-Fi is okay but your internet is unavailable
Obstacles in your home such as walls, floors, and furniture can reduce Wi-Fi range. With a poor Wi-Fi signal, your thermostat may then fail to connect or may connect but lose signal. To troubleshoot your Bosch thermostat if it doesn’t connect to Wi-Fi or loses connection start by testing to see if the thermostat is experiencing a poor Wi-Fi signal. There are two tests you can do to check for that: If you experience a good Wi-Fi connection on the thermostat via your smartphone hotspot or with it powered up next to the router, then this may indicate that the wall mount location for the thermostat is too far from the router. This is likely the issue if there are obstacles between the router and the thermostat’s wall mount location. Consider moving the thermostat to a location closer to the router. If you are still experiencing Wi-Fi problems with the thermostat powered up next to the router or via your smartphone hotspot, and no other devices are having connection issues, then there could be a technical problem with the thermostat itself. Please note that the Bosch Connected Control thermostat is only compatible with 2.4Ghz Wi-Fi systems, and will not work with 5Ghz systems or webpages that require additional web authentication.

Bosch BCC50 Troubleshooting
Wi-Fi
If you are having trouble connecting to your Home’s Wi-Fi network:
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 an obstruction exists, try moving your thermostat and router closer together.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.
Note that 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.
Initial Setup
If you are having trouble connecting your BCC50 Wi-Fi hotspot during initial setup:
Go to your phone’s Wi-Fi settings and forget the BCC50 Wi-Fi hotspot. Power cycle the thermostat and try the initial setup again.
If you are having trouble advancing to the Unit Configuration portion of the Initial Setup:
Some devices have longer wait times to transfer from the Wi-Fi hotspot connection to the Unit Configuration. If the wait times exceed 60 seconds, repeat the Initial Setup process.

Bosch Thermostat Temperature Readings Not Accurate
The first thing to check when your thermostat readings seem to be off is your settings. Check whether the thermostat was set to heat or cool. Besides the settings, there are several other possible causes that you need to check:
Poor thermostat placement
Thermostat placement is very important. It should be located in a part of your home that is most representative of the overall ambient temperature of the house. It should be kept away from places like doors that let in a draft or walls that get direct sunlight in the afternoon. Basically, the thermostat placement should not be in parts of your house that face drastic temperature swings.
A bad temperature sensor
A faulty temperature is another cause for a thermostat to be reading the wrong temperature in your home. Sometimes sensors can break or degrade in harsh environments. The following are steps for troubleshooting a faulty sensor:
Check +ve and –ve leads are correctCheck you are using the correct type of cableCheck for local heat sources affecting your readings. If your thermocouple is reading high, it could be because your sensor is located too close to a heat source.Check setup of your temperature controller/readoutResolve out of range errorsResolve Sensor Break/Open circuit errorsCheck temperature transmitterTest faulty thermocouple with a multimeter. Change your multimeter to Continuity beeper/diode symbol/flow of current. Some multimeters will beep if there is a break in the circuit, others will beep when the circuit is complete. So, know how your multimeter functions.
Bosch Thermostat Screen Not Responding
The screen may be locked and if so, you need to input the password to unlock it. If you have forgotten the password, you can reset it via the mobile app, or by physically removing the thermostat from the wall plate, wait for a few seconds, and then replacing it back onto the plate. To unlock a BCC50 thermostat screen, click the green lock button in the top right-hand corner of the thermostat. If your thermostat screen is not turning on it could be because there is no power running to the thermostat or the power is insufficient. This can happen when installation wiring is defective or the thermostat was not wired correctly. To test if wiring is the issue follow these steps: To fix the problem, get an electrician to investigate and rectify the power supply or wiring issue. Note that a C-wire (common wire) is required to power the unit. Two-wire systems are not supported.
