Installation

Turn off power to HVAC system at circuit breaker before installation.

Remove old thermostat: Label existing wires, disconnect from old unit.
Mount new baseplate: Level and secure to wall using provided screws.
Connect wires: Insert labeled wires into corresponding terminal screws (R, W, Y, G, C, etc.).
Attach thermostat: Align and snap onto baseplate.
Install batteries: Insert 2 AA batteries for backup power.
Restore power: Turn circuit breaker back on.

WARNING! Electrical shock hazard. Ensure power is off before handling wires. If unsure, consult a qualified HVAC technician.

First-Time Setup

After installation and power restoration, configure initial settings.

Set time and day: Press MENU, navigate to CLOCK SETTINGS, enter current time and day.
Select temperature format: Choose Fahrenheit (°F) or Celsius (°C).
Configure system type: Set for conventional or heat pump system in INSTALLER SETUP.
Set heating/cooling stages: Configure for single or multi-stage equipment.
Program schedule: Follow prompts to set 4 periods per day (Wake, Leave, Return, Sleep).

CAUTION! Incorrect system configuration may cause equipment damage. Refer to HVAC system manual or contact professional.

Controls and Settings

Front Panel: MENU, UP/DOWN arrows, SYSTEM (Heat/Cool/Auto/Off), FAN (Auto/On), HOLD.

Menu Navigation: Press MENU to access: PROGRAM SCHEDULE, CLOCK SETTINGS, PREFERENCES, INSTALLER SETUP, FILTER TIMER, VACATION SETTINGS.

Temperature Adjustment: Use UP/DOWN arrows to set desired temperature. System Mode: Select HEAT, COOL, AUTO (automatically switches between heat and cool), or OFF. Fan Control: AUTO (runs only when heating/cooling) or ON (continuous operation). Hold Function: Temporarily maintains current temperature until next scheduled period. Keypad Lock: Press and hold MENU for 5 seconds to lock/unlock.

Connecting to HVAC System

Ensure proper wire connections for system operation.

Identify wires: Common terminals: R (24V power), W (heat), Y (cool), G (fan), C (common).
Heat pump systems: Additional O/B terminal for reversing valve.
Multi-stage systems: Use W1/W2 for heat stages, Y1/Y2 for cool stages.
Auxiliary heat: Connect to Aux/E terminal for heat pump backup heat.
Verify connections: Ensure wires are secure and not touching each other.

Tip: Take a photo of original thermostat wiring before disconnecting for reference.

Programming Schedule

Create custom temperature schedules for energy efficiency.

Access program: Press MENU, select PROGRAM SCHEDULE.
Select day: Choose ALL DAYS, WEEKDAYS, WEEKENDS, or individual days.
Set periods: Configure 4 periods: WAKE (morning), LEAVE (day), RETURN (evening), SLEEP (night).
Set temperatures: For each period, set separate heat and cool temperatures.
Copy schedule: Copy settings from one day to other days to save time.
Review program: Scroll through all days to verify settings.
Exit: Press MENU to save and return to main screen.

WARNING! Extreme temperature settings may cause discomfort or system strain. Recommended difference between heat and cool settings is at least 3°F.

Energy Saving Features

Energy Recovery: Calculates optimal start time to reach set temperature by scheduled period. Adaptive Intelligent Recovery: Learns system performance to improve temperature timing. Filter Change Reminder: Set interval (30-365 days) for maintenance alerts. Vacation Mode: Set extended away periods with energy-saving temperatures.

Care & Cleaning

Turn off power before cleaning. Use soft, dry cloth to clean display and casing. Do not use liquids, sprays, or abrasive cleaners.

CAUTION! Never spray cleaning solutions directly on thermostat. Moisture can damage electronics.
