Thermostat Not Connecting to WiFi

Symptoms

  • WiFi setup fails
  • Network not found
  • Connection times out

Solutions

  1. 2.4GHz network - BCC50 only supports 2.4GHz WiFi networks.
  2. Enter network manually - If SSID not found, enter network name and password manually.
  3. Check signal strength - Thermostat location may have weak WiFi. Consider a WiFi extender.
  4. Factory reset - Menu > Settings > Reset > Factory Reset, then reconfigure.

Heating/Cooling Not Responding

Symptoms

  • Temperature never reaches setpoint

Solutions

  1. Check system settings - Verify Heat/Cool/Auto mode is selected correctly for season.
  2. Wiring verification - Confirm wires are connected correctly per Bosch wiring guide.
  3. C-wire - Common wire (C) provides power. Without it, WiFi features may be unreliable.

  4. Re-register thermostat - Remove and re-add thermostat in app if sync issues persist.

Symptoms

  4. Check thermostat name - Rename to something easy to say like "Living Room Thermostat."
