Safety Information
WARNING: Electrical Shock Hazard.
- Always turn off power to the heating and cooling system at the main fuse or circuit breaker panel before installing or servicing the thermostat. Failure to do so could result in electrical shock, property damage, or personal injury.
- This thermostat is designed for low voltage (24 Volts) systems only. Do not use it with 115/230V line voltage systems.
- If you are unsure about any part of the installation process, it is recommended to consult a qualified HVAC technician or electrician.

Installation
1. Pre-Installation Steps
- Turn Off Power: Locate the circuit breaker or fuse box that controls your heating and cooling system. Turn off the power to prevent electrical shock.
- Remove Old Thermostat: Carefully remove the cover of your old thermostat. Take a clear picture of the wiring connections before disconnecting any wires. This will serve as a reference for connecting the new thermostat. Label each wire with the terminal designation it was connected to (e.g., R, G, Y, W).
- Check System Compatibility: Ensure your HVAC system is compatible with this thermostat. This model is compatible with most 24V heating and cooling systems, including gas/oil/electric furnaces (heating only or single stage), heat pumps without auxiliary heat, 2-wire hydronic (hot water) systems, and 750 millivolt gas fireplaces. It is NOT compatible with heat pump multistage, radiant ceiling heat, electric baseboards, heat pumps with auxiliary heat, portable space heaters, 3-wire hydronic (hot water) systems, gas/oil/electric furnace multistage, cool multistage, or plug-in air conditioners.
Refer to this chart to confirm your system's compatibility with the Lux Pro PSD011B thermostat.
2. Mounting the New Thermostat
- Separate Wall Plate: Gently separate the front of the new thermostat from its wall mounting plate. This is typically done by pressing a tab or gently pulling the two halves apart.
- Position Wall Plate: Hold the wall plate against the wall where you want to mount the thermostat. Thread the existing thermostat wires through the opening in the wall plate.
- Secure Wall Plate: Use the provided mounting screws and wall anchors (if needed) to securely fasten the wall plate to the wall. Ensure it is level for aesthetic purposes.
3. Wiring
Connect the wires from your wall to the corresponding terminals on the new thermostat's wall plate. Refer to the picture you took of your old thermostat's wiring and the labels you made. This model is primarily battery-powered, so a common (C) wire is not strictly required for operation, but it can be connected if available for continuous power to the display. If a C-wire is present and you wish to use it, connect it to the 'C' terminal. Otherwise, ensure the batteries are installed.
The control panel diagram illustrates the location of the quick and easy temperature change buttons, fan slide switch, and mode slide switch.
Typical Wiring Connections:
- R/Rh: 24V Power (Heating)
- Rc: 24V Power (Cooling) - Often jumped with R/Rh if only one transformer.
- W1: Heat (First Stage)
- Y1: Cool (First Stage)
- G: Fan
- C: Common (Optional for continuous power, otherwise battery-powered)
4. Battery Installation
This thermostat operates on 2 AA batteries. Insert the batteries into the battery compartment located on the back of the thermostat unit. Ensure correct polarity (+/-). If a black plastic tab is present in the battery compartment, remove it prior to installation to activate the batteries.
The Lux Pro thermostat is designed for battery-only operation, featuring a large back-lit display for easy reading.
Once batteries are installed, snap the thermostat front onto the wall mounting plate. Turn the power back on at the circuit breaker.
Operating Instructions
Your Lux Pro PSD011B thermostat is designed for straightforward operation.
1. Setting the Temperature
- Use the ▲ (Up) and ▼ (Down) arrow buttons to adjust the desired temperature. The display will show the set temperature.
- The thermostat will automatically maintain the set temperature.
- Adjustable temperature stops allow for precise control over your comfort settings.
2. System Mode Selection
Use the System Mode slide switch located on the side of the thermostat to select your desired operating mode:
- HEAT: The thermostat will control your heating system to maintain the set temperature.
- OFF: The heating and cooling systems are turned off.
- COOL: The thermostat will control your cooling system to maintain the set temperature.
3. Fan Mode Selection
Use the Fan Mode slide switch located on the side of the thermostat to select your desired fan operation:
- AUTO: The fan runs only when the heating or cooling system is actively operating. This is the most energy-efficient setting.
- ON: The fan runs continuously, regardless of whether the heating or cooling system is actively operating.
Maintenance
- Battery Replacement: Replace the 2 AA batteries annually, or when the low battery indicator appears on the display. To replace, gently pull the thermostat unit off the wall plate, replace the batteries, and snap it back into place.
- Cleaning: Clean the thermostat with a soft, damp cloth. Do not use abrasive cleaners or solvents.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Blank screen | Dead batteries. | Replace the 2 AA batteries. |
| Heating/Cooling system not responding | Power is off at the circuit breaker. Incorrect system mode selected. Wiring issue. |
Check the circuit breaker and turn power on. Ensure the system mode switch is set to HEAT or COOL. Verify all wiring connections are secure. Consult a professional if unsure. |
| Fan not operating in AUTO mode | System is not calling for heating or cooling. | This is normal. The fan will only run when the system is active. Switch to ON mode for continuous fan operation. |
| Inaccurate temperature reading | Thermostat location is affected by drafts, direct sunlight, or heat sources. | Ensure the thermostat is not exposed to extreme conditions. Relocate if necessary. |
