Installation

Turn off power to HVAC system before installation. Mount on interior wall away from direct sunlight and drafts.

Remove old thermostat: Turn off power, remove cover, label wires, disconnect from terminals.
Mount new baseplate: Level and secure to wall, feed wires through opening.
Connect wires: Match labeled wires to corresponding terminals (R, W, Y, G, C).
Attach thermostat: Snap onto baseplate, restore power to HVAC system.
Configure settings: Follow first-time setup procedure.

WARNING! Always turn off power before installation to prevent electrical shock. Use proper wiring techniques.

First-Time Setup

After installation, configure basic settings for proper operation.

Set date and time: Access TIME menu, set current date and time.
Configure temperature units: Select Fahrenheit or Celsius in SETTINGS.
Set program schedules: Create wake, leave, return, sleep schedules.
Test system operation: Verify heat and cool modes function properly.
Set filter reminder: Program filter change interval (1-12 months).

CAUTION! Ensure proper wiring before restoring power. Incorrect installation may damage HVAC system.
