1. Before starting, turn the power off at the breaker box or switch. Open the package to find the UWP. 2. Position the UWP on the wall. Level and mark hole positions. 3. Using a 3/16″ bit, drill holes at marked positions and then lightly tap the supplied wall anchors into the wall using a hammer. 4. Pull the door open and insert the wires through the wiring hole of the UWP. 5. Place the UWP over the wall anchors. Insert and tighten mounting screws supplied with the UWP. Do not overtighten. Tighten until the UWP no longer moves. Close the door. Use the 3x supplied #6 1-1/2″ screws.

Use the Optional Cover Plate when you need to cover a paint gap from the old thermostat. 1. Separate the Cover Plate from the Mounting Plate. 2. Mount the Mounting Plate onto the wall or J-box using any of the 8 screw holes. Insert and tighten mounting screws supplied with the Cover Plate Kit. Do not overtighten. Make sure the Mounting Plate is level. 3. Attach the UWP by hanging it on the top hook of the Mounting Plate and then snapping the bottom of the UWP in place. 4. Snap the Cover Plate onto the Mounting Plate.

• AC Power: Insert R and C wires into designated terminals for AC power. Remove wires by pressing down on the terminal tabs. The C terminal is required for S200 Smart thermostats. If you do not have a C wire, you may use the THP9045A C-wire adapter (sold separately).
• Battery Power (P200 Models Only): Insert 2 fresh AA batteries for primary or backup power.

Use the built-in jumper (R Slider Tab) to differentiate between one or two transformer systems:

• If there is only one R wire, and it is connected to the R, Rc, or RH terminal, set the slider to the up position (1 wire).
• If there is one wire connected to the R terminal and one wire connected to the Rc terminal, set the slider to the down position (2 wires).

Slider Tabs for U terminals should be left in place.

1. Press the MODE button to cycle to the next available System mode. 2. Cycle through the modes until the desired System mode is displayed. Available System modes vary by model and system settings, but may include:

• AUTO: Thermostat selects heating or cooling as needed (if enabled in ISU 3000).
• HEAT: Controls only the heating system.
• COOL: Controls only the cooling system.
• EM HEAT: Emergency Heat (for heat pump systems). Controls only backup heat.
• OFF: Heating and cooling systems are off.

1. Press the FAN button to cycle to the next available Fan mode. 2. Cycle through the modes until the desired Fan mode is displayed. Available Fan modes vary with system settings, but may include:

• AUTO: Fan runs only when the heating or cooling system is on (default for most systems).
• ON: Fan runs continuously.
• CIRC: Fan runs intermittently, about 33% of the time, to circulate air.

When the thermostat is set to Auto Changeover mode (System Mode set to AUTO), it maintains separate Heat and Cool setpoints. 1. Ensure the thermostat is in AUTO mode (press MODE until AUTO shows). Press SAVE (center left button). 2. Press ↑ or ↓. The upper right display shows either HEAT TO or COOL TO flashing, along with the corresponding setpoint. 3. Use ↑ or ↓ to adjust the displayed setpoint (Heat or Cool). 4. If you want to adjust the other setpoint (e.g., adjust Cool when HEAT TO is flashing), press the MODE button. This will switch the flashing text between HEAT TO and COOL TO and allow adjustment of the other setpoint. The thermostat will automatically run heating or cooling as needed to keep the room temperature between the Heat and Cool setpoints. A differential (set in ISU 3015) prevents rapid switching between modes.

Yes, the Heat and Cool setpoints can technically be set to the same temperature. However, most users prefer a 2-3 degree difference. To prevent the system from constantly switching between heating and cooling if the setpoints are close or the same, the thermostat uses an Auto Changeover Differential (set in ISU 3015, default 0°F/0°C but typically needs to be higher, e.g., 3°F/1.5°C). If the system last ran Heat, the temperature must rise above the Cool setpoint by the differential amount before it switches to Cool mode. If it last ran Cool, the temperature must drop below the Heat setpoint by the differential amount before it switches to Heat mode. This prevents short cycling between heating and cooling.

When an alert is active, an alert icon (triangle with exclamation mark) appears in the lower part of the display. 1. Press MENU. Active alerts will be the first menu items shown. Use ↑ or ↓ if needed to scroll to the alert message. 2. Press SELECT to display the alert number (e.g., 405). 3. If there is more than one active alert, pressing NEXT allows you to view additional alert numbers. 4. Alerts cannot be dismissed directly (except for “Set Time and Date” by setting the time/date). They clear automatically when the condition is resolved (e.g., replacing batteries clears alert 405/407). Press EXIT to return to the home screen.

Adaptive Intelligent Recovery (AIR), also known as “Learning”, is a comfort feature (enabled/disabled in ISU 4090). When active, “Recovery” appears on the display below the room temperature as the thermostat transitions from an energy-saving setpoint (like Away or Sleep) to a comfort setpoint (like Wake or Home). Over time, the thermostat learns how long your heating or cooling system takes to reach the desired temperature. It then starts the heating or cooling system earlier than the scheduled time, ensuring the indoor temperature matches the setpoint exactly *at* the scheduled time (e.g., the house is already at 70°F when the Wake period begins at 6:00 AM).

This feature prevents damage to your cooling system’s (or heat pump’s) compressor that could occur if it is restarted too quickly after shutting down. The thermostat enforces a minimum off-time (typically 5 minutes, set in ISU 3240). During this waiting period, the display will show the message “Waiting For Equipment” below the room temperature reading, and the system will not start cooling (or heating in heat pump mode). Once the safe wait time has elapsed, the message disappears, and the system can start normally (“Cool On” or “Heat On” will appear).

This applies to FocusPRO N100, P200, and S200 models, often used for private labeling. 1. Gently pull the existing accent piece (the bottom curved piece, often with branding) away from the main body of the thermostat. It should detach. 2. Align the new accent piece with the bottom of the thermostat. 3. Push the new accent piece gently until it snaps securely into place.

The thermostat display will indicate when batteries are low (Alert 405 or 407). 1. Grasp the thermostat body and gently pull it straight away from the UWP wall plate it’s mounted on. 2. Turn the thermostat over and remove the old AA batteries. 3. Insert two new, fresh AA alkaline batteries, observing the polarity markings (+/-) inside the battery compartment. 4. Align the thermostat back onto the UWP wall plate. 5. Push gently until the thermostat snaps back into place.

• Check the circuit breaker for the HVAC system and reset if necessary.
• Make sure the power switch for the heating & cooling system is on.
• Make sure the furnace or air handler access door is closed securely.
• For P200 models: Make sure fresh AA alkaline batteries are correctly installed.
• For S200 models (or P200 using C-wire): Ensure the C-wire connection is secure and providing 24VAC.

• Check the display: “HEAT ON” should appear in the lower right when heating is called for, “COOL ON” when cooling is called for.
• If “WAITING FOR EQUIPMENT” is displayed, the compressor protection delay is active. Wait 5 minutes.
• Verify System Mode: Press MODE to ensure it’s set to HEAT or COOL as desired (or AUTO if enabled).
• Check Setpoint vs. Room Temp: Press ↑ or ↓. The upper right shows the setpoint, the center shows the room temperature. Ensure the setpoint requires heating (setpoint > room temp) or cooling (setpoint < room temp).
• Check circuit breaker and reset if necessary.
• Make sure the power switch at the heating & cooling system is on.
• Make sure the furnace/air handler door is closed securely.

• Heat Pump Systems Only: Verify the Reversing Valve setting (ISU 2060 – O/B). Some heat pumps energize the valve for heating (B setting), others for cooling (O setting). Ensure the ISU setting matches your equipment.
• Check for Shorted Wires: Inspect wiring at the thermostat UWP wall plate. Look for any exposed sections of wires that might be touching each other, particularly between heating (W, W2, E) and cooling (Y, Y2) or power (R, Rc) terminals.

• Verify Display: Ensure the display does not indicate HEAT ON, COOL ON, or AUX HEAT ON.
• Heat Pump Systems: Verify that no wire is connected to the W terminal on the UWP. The W terminal is generally NOT used for heat pump systems (Aux/backup heat connects to AUX/W2 or E). Check wiring diagrams.
• Check for Shorted Wires: Inspect wiring at the thermostat UWP wall plate. Look for exposed wire sections that might be shorted, potentially causing the heat circuit to be energized improperly.

• Check Keypad Lockout: If UNLOCK appears next to the left center button when you try to change the setpoint, the keypad is locked. Follow the unlocking procedure (password 1234).
• Check System Mode: Ensure the thermostat is in the correct mode (Heat, Cool, Auto, Em Heat) for the setpoint you are trying to adjust. Press the MODE button to cycle if needed.
• Check Temperature Ranges: Verify the desired setpoint is within the allowed range for the current mode:
  • Heat or Em Heat: 32 °F to 90 °F (0 °C to 32.0 °C)
  • Cool: 50 °F to 99 °F (10.0 °C to 37.0 °C)
• Check Setpoint Limits (ISU): The installer may have configured minimum and maximum setpoint limits (ISU 4100-4103) to restrict the range for energy efficiency. If you cannot reach the full range above, these limits might be active.

This message indicates that the built-in compressor protection feature is engaged. The thermostat is waiting for a short period (usually 5 minutes) before starting the compressor to prevent potential damage from short-cycling. Wait a few minutes, the message should disappear, and the system should start normally.
