- Compatibility: The thermostat is compatible with 24 VAC HVAC equipment, including heat pump (4 Heat, 2 Cool) and conventional (2 Heat, 2 Cool) systems. It also supports one 1-wire internally powered humidifier or dehumidifier.
- Tools Required: Screwdriver, wall anchors (included), wire labels (included).
2.2 Physical Installation
- Turn Off Power: Before beginning installation, ensure the power to your HVAC system is completely turned off at the circuit breaker.
- Remove Old Thermostat: Carefully remove your existing thermostat from the wall. Take a photo of the current wiring configuration for reference. Label each wire using the provided wire labels.
- Mount Wall Plate: Position the BCC100 wall plate on the wall where you intend to install the thermostat. Use the provided screws and wall anchors to secure it firmly. Ensure the plate is level.
- Connect Wiring: Connect the labeled wires from your HVAC system to the corresponding terminals on the BCC100 wall plate. Refer to the wiring diagram in the included manual for specific connections. Ensure the C-wire is properly connected.
- Attach Thermostat: Align the BCC100 thermostat unit with the wall plate and gently push it into place until it clicks securely.
