Operation Instructions

Initial Setup

1. Insert Batteries: Install two "AA" alkaline batteries in the slot at the top of the thermostat, ensuring correct polarity.
2. Power On: If hardwired, connect 18-30 VAC to the appropriate terminals. The display should show the current time and temperature.
3. Configure System:

Access installer settings menu to set system type (e.g., conventional or heat pump), differentials, cycle rates, backlight, temperature scale (°F/°C), programming periods.
Set user options: clock format, service monitors, override limits.
Set time and day: Use SpeedBar to adjust, ensure AM/PM is correct.
Program schedule: Press PROG, set events for residential (4 events: Wake, Leave, Return, Sleep) or commercial (2 events).

Operating the Thermostat

1. Select Mode: Press SYSTEM to choose AUTO, COOL, OFF, HEAT, or EMER (emergency heat for heat pumps).
2. Fan Mode: Press FAN to select AUTO, ON, or PROG (programmable fan).
3. Adjust Temperature: Use SpeedBar up/down to set desired temperature. For temporary override, adjust in program mode; for permanent hold, press HOLD. Cancel hold by pressing RUN SCHEDULE.
4. Programming: Press PROG to enter mode, customize schedules for 5-2, 5-1-1, 7-day, or non-programmable. Use factory pre-programmed energy-saving settings if desired.
5. Verify Operation: In HEAT, set above room temp; status shows heating. In COOL, set below; shows cooling. Adaptive Recovery adjusts start time to reach setpoint.
Note: View outdoor temperature by pressing PROG and HOLD if sensor connected. Lock thermostat with 3-digit code for security.

Temperature Display Adjustment

The thermostat has +/-1°F accuracy. Adjust temperature scale (°F/°C) in installer settings. No specific calibration adjustment available; use a separate thermometer to verify. Relocate if near drafts or heat sources. Indoor remote sensing option available if configured.

Troubleshooting

No Display: Check battery polarity or replace batteries. Verify 24V power if hardwired.
No Heat/Cool: Ensure mode is correct, setpoint appropriate, power on. Check wiring, breakers. For heat pumps, try EMER mode.
Fan Runs Constantly: Set FAN to AUTO or PROG, not ON.
Inaccurate Temperature: Ensure proper location away from drafts/heat sources. Check sensor settings.
Erratic Operation: Check for voltage issues or reset thermostat.
Service Indicators: Reminders for filter, UV, humidifier; reset after maintenance.
Buttons Not Working: Replace batteries.

Installation Instructions

Warning: For experienced technicians only. Disconnect power before installation to prevent shock or damage. Thermostat requires 24V AC or 2 "AA" batteries. Conform to local codes.

Remove Old Thermostat

Turn off power at circuit breaker. Remove old thermostat, label wires for terminals. Handle mercury thermostats carefully and dispose properly per regulations.

Installing New Thermostat

Separate thermostat body from sub-base.
Mount sub-base on wall, mark and drill holes, use anchors if needed.
Connect wires to terminals per wiring reference (e.g., Rc/Rh for power, W1/E for heat, Y1 for cool, G for fan).
Set advanced installer settings: system type, differentials, etc.
Push excess wire back, plug hole with insulation to prevent drafts.
Snap thermostat body onto sub-base.

Battery Location

Batteries stored in slot at top of thermostat. Replace when low battery indicator shows. Use alkaline "AA" batteries.
If unoccupied for long periods, replace batteries before leaving.

Power Options

Use 24V AC for primary power with batteries as backup, or batteries only.

Thermostat Power Method	Description
Battery Powered	Runs on two "AA" batteries.
Hardwired with Battery Backup	Runs on 18-30V AC from transformer with batteries as backup.

Caution: Ensure correct polarity for batteries. Do not short terminals during testing.
