Operation Instructions

Initial Setup

1. Turn Off Power: Always turn off power to the heating/air conditioning system prior to installing or adjusting the thermostat.
2. Configure System:

Hold MENU for 5 seconds to enter installer settings.
Use NEXT (HOLD) to advance, BACK (PROG) to go back, up/down arrows to change values.
Set options like PROG MODE, DEG, DIF1, DIF2, CSCP, REC, FILTER, HOLD, OVERRIDE, SEC, REV VALVE.
Exit with MENU.

Operating the Thermostat

1. System Mode: Select COOL, OFF, HEAT, EMER using the SYSTEM switch. EMER activates auxiliary heat only.
2. Fan Mode: AUTO or ON using the FAN switch.
3. Temperature Setpoint: Use up/down arrows to adjust; OVERRIDE for temporary, HOLD for extended override.
4. Programming: Press PROG to enter, select day/group, set time and temperature for MORN, DAY, EVE, NITE events. Use SpeedSet by holding PROG for 3 seconds.
5. Display: Shows current time, temperature, program event, system status (HEAT ON, COOL ON, AUX ON), fan status, SERVICE FILTER.
Note: Adaptive Recovery starts system early to reach setpoint by program time. Compressor protection delays restart. In EMER mode, heat pump is bypassed.

Temperature Display Adjustment

Configure temperature scale (°F/°C) in installer settings under DEG. No direct calibration; accuracy is +/-1°F. Use separate thermometer for verification if needed.

Troubleshooting

No Display: Check batteries or 24V power, polarity.
No Heat/Cool: Verify system mode, setpoint, wiring, short cycle delay.
Fan Constant: Check fan mode, wiring.
Erratic Operation: Check voltage, batteries, reset by removing batteries/power for 2 minutes.
Low Battery: Battery symbol appears; replace batteries.
Service Filter: Reminder after set days; reset in user settings.
CHECK Indicator: System issue (L terminal active); contact technician.
Reset: Remove batteries/power for 2 minutes to reset.

Installation Instructions

Warning: Turn off power before installation. For experienced technicians only. Use only with compatible systems; conform to local codes. Provide disconnect and overload protection.

Remove Old Thermostat

Turn off power. Disconnect wiring, note connections. Remove old mounting hardware and thermostat.

Installing New Thermostat

Mount sub-base level on wall, approximately 5 ft above floor, avoiding drafts/sunlight. Drill holes, secure with screws/anchors.
Connect wiring: Rc/Rh (jumper for single transformer), W1/E, W2, Y1, G, O/B, L, C (common). Set factory switches to CONV/HP and HG/HE.
Insert batteries if using battery power.
Configure installer settings.
Snap thermostat body onto sub-base.
Apply power, test system.

Battery Location

Batteries are located in the rear housing of the thermostat body. Remove body from sub-base, replace 2 AA alkaline batteries ensuring correct polarity.

Power Options

Hardwired with 24 VAC or battery powered.

Power Method	Description
