2. Safety Information
Always observe the following safety precautions to prevent personal injury or damage to the thermostat and connected equipment:
- Power Disconnection: Always disconnect power to the heating/cooling system at the main fuse or circuit breaker panel before installing or servicing the thermostat.
- Electrical Hazard: This thermostat operates on low voltage. However, improper wiring can cause damage to the thermostat or the HVAC system. If you are unsure about wiring, consult a qualified HVAC technician.
- Battery Safety: Use only recommended battery types (2 AA alkaline batteries). Do not mix old and new batteries, or different types of batteries. Dispose of used batteries properly.
- Location: Install the thermostat away from direct sunlight, drafts, and heat sources (e.g., lamps, fireplaces) to ensure accurate temperature readings.
- Cleaning: Use a soft, damp cloth for cleaning. Do not use abrasive cleaners or solvents.

4. Setup and Installation
Follow these steps carefully to install your new thermostat. If you are replacing an existing thermostat, take a picture of the old wiring before disconnecting any wires.
- Turn Off Power: Locate the circuit breaker or fuse box that controls your heating and cooling system and turn off the power. Verify power is off by attempting to turn on your system.
- Remove Old Thermostat (if applicable): Carefully remove the old thermostat cover. Disconnect wires one by one, labeling each wire with the terminal it was connected to (e.g., R, W, Y, G, C). Take a photo of the wiring for reference.
- Remove Old Wall Plate: Unscrew and remove the old wall plate.
- Mount New Wall Plate: Thread the wires through the opening in the new Emerson wall plate. Secure the wall plate to the wall using the provided screws and wall anchors. Ensure it is level.
- Connect Wiring: Refer to your labeled wires and the wiring diagram on the back of the thermostat or in the installation guide. Connect each wire to the corresponding terminal on the new wall plate. The UP310 supports systems with or without a 'C' (common) wire, as it can be battery-powered.
- Install Batteries: Insert the two AA alkaline batteries into the battery compartment on the back of the thermostat unit.
- Mount Thermostat: Align the thermostat unit with the wall plate and gently push it onto the plate until it clicks securely into place.
- Restore Power: Turn the power back on at the circuit breaker or fuse box.
- Initial Setup: The thermostat display should illuminate. Follow the on-screen prompts for initial setup, which may include setting the current time and date. Access the installer menu (often by holding the 'Menu' button for 8 seconds) for advanced system configuration if necessary.
