Programming Basics

To program the Pro1 T705 thermostat, first press the Menu button and navigate to Schedule. The device supports two primary scheduling modes: the default 5‑day (511) schedule and a 7‑day (7d) schedule. If the 7d option is not visible, ensure the firmware is up‑to‑date; older releases may hide this setting. Select the desired mode and use the arrow keys to set the start and end times for each day. The T705 allows separate heating and cooling setpoints for each time block, giving fine‑grained control over indoor comfort. After entering a block, press Enter to confirm, then proceed to the next block. When finished, press Back to return to the main menu.

Temperature units can be toggled by selecting Units in the main menu. The thermostat will display the current setpoint in either Fahrenheit or Celsius, and the display will automatically convert the ambient temperature accordingly. For systems that require a 24‑hour clock, choose 24‑Hour Format under Time Settings. The T705 also includes a Run Schedule toggle; enabling this will cause the thermostat to follow the programmed times automatically, while disabling it forces manual control.

Each day’s schedule is stored in non‑volatile memory, so power loss will not erase your settings. The T705’s Backup feature can be accessed by holding Menu for three seconds; this creates a copy of the current configuration to the internal flash, which can be restored if necessary. Finally, remember to test the schedule by temporarily setting a short time block and verifying that the thermostat responds as expected.

Weekly Schedule Configuration

To set a weekly schedule on the Pro1 T705, press the Menu button and select Schedule. The thermostat offers a 5‑day (511) or 7‑day (7d) format; choose the desired mode by tapping Mode and scrolling to the appropriate icon. Once the mode is selected, use the Arrow keys to navigate to the day you wish to program. The screen will display the current setpoints and time blocks for that day.

Enter a new block by pressing Enter and then set the start time. Use the Hour and Minute arrows to adjust the clock, and toggle between AM/PM if you are in 12‑hour mode. After confirming the start time, set the end time in the same way. The T705 allows you to specify separate heating and cooling setpoints for each block; choose Heat or Cool and input the desired temperature using the numeric keypad.

When you have finished configuring a block, press Back to return to the day’s list. Repeat the process for each day of the week. The thermostat stores each block in non‑volatile memory, so the schedule persists after power loss. To review or edit a block, simply navigate to the day and select the block number. The display will show the current settings, and you can adjust them as needed.

Once all days programmed, press Menu again to exit. The T705 will now follow the weekly schedule automatically unless the Run Schedule toggle is turned off. For systems that require a 24‑hour clock, ensure the 24‑Hour Format option is enabled in Time Settings. This configuration provides precise control over heating and cooling throughout the week.

Advanced users can also import schedules via the companion mobile app, which syncs over Wi‑Fi. The app provides a graphical interface to drag and drop time blocks, making it easier to adjust seasonal changes. Additionally, the T705 supports a Holiday Mode that temporarily overrides the weekly schedule; enable it by selecting Holiday in the main menu and setting the desired dates. When the holiday period ends, the thermostat automatically reverts to the programmed weekly schedule. For troubleshooting, the Diagnostics screen shows the last scheduled event and any conflicts that may arise from overlapping time blocks.

Temperature Units and Conversion

The Pro1 T705 displays temperatures in either Celsius (°C) or Fahrenheit (°F). To switch units, press the Menu button, select Units, and tap the desired symbol. The thermostat automatically recalculates all setpoints and historical data to the new scale, preserving the numeric values; For example, a 22 °C setpoint becomes 71.6 °F, and a 75 °F setpoint becomes 23.9 °C. The display updates instantly, and the Temp Sensor icon changes to reflect the unit. Users can also set a Display Offset to fine‑tune the reading by ±0.5 °C or ±1 °F, useful for calibration against a reference thermometer. The T705 logs temperature trends in the selected unit; the History screen shows a graph with labeled axes. When the thermostat is in Auto mode, the unit setting does not affect the HVAC logic—only the display and setpoint values. For remote monitoring via the companion app, the unit preference is synced automatically, ensuring consistency across devices. If you need to convert a setpoint manually, use the quick reference: 1 °C ≈ 1.8 °F. The T705’s firmware supports both units natively, so there is no need for external conversion tools. Always verify the unit after a firmware update, as some updates may reset the unit to the default Celsius. The unit setting is stored in non‑volatile memory, so power cycles do not change it. If you encounter a display glitch after toggling units, press Reset in the Advanced menu to restore defaults. Toggle units quickly for precision. This feature ensures that the thermostat remains accurate and user‑friendly regardless of the chosen temperature scale.

Battery Management

The Pro1 T705 runs on a single 3 V CR2032 button cell that can be replaced via the front battery door. Lift the finger bevel on the lower side of the thermostat and slide the door open. A low‑battery icon appears on the main screen when voltage falls below 2.5 V, prompting a replacement. A fresh battery restores the icon within seconds. The firmware monitors voltage in real time and will pause any scheduled HVAC activity if the battery drops below the critical threshold, preventing the unit from attempting to run on insufficient power. To extend life, disable the backlight or set a lower brightness level in the Display menu. The thermostat also supports an optional external 5 V DC adapter; when connected, the battery indicator remains active but the unit will not drain the cell. When replacing the battery, orient the positive side upward and press firmly until it clicks into place. After replacement, reset the unit by holding the Menu button for 3 seconds; the display will clear the low‑battery flag and recalibrate the voltage sensor. If the icon persists after a new cell is installed, check for a damaged battery contact or a faulty door seal that may be causing a short. The T705’s battery management system is designed for reliability, and regular checks keep the thermostat responsive and ready for any HVAC schedule!!!

For advanced users, the T705 offers a diagnostic mode that displays raw voltage readings. Hold the Up button while turning the thermostat on; the screen shows millivolts, helping you spot a marginal battery before the low‑battery warning triggers.

Store spare batteries in a cool, dry place and avoid extreme temperatures, which shorten lifespan. A quick visual check of contacts for corrosion prevents false low‑battery alerts.

Troubleshooting Common Issues

When the T705 fails to honor a programmed schedule, first verify that the device is in the correct mode. The thermostat can be set to Non‑Programmable (0d) or 5‑Day (511). If the 7‑Day (7d) option is missing, the firmware may be outdated. Download the latest firmware from the official Pro1 website and flash the unit using the USB interface. After updating, reboot and navigate to Settings > Schedule; the 7d menu should appear. If the 7d option still does not display, the unit may be a 5d variant; contact support for a hardware confirmation. A common symptom is the thermostat displaying the low‑battery icon while the cell is fully charged. This can occur if the battery contacts are dirty or if the door seal is not fully closed. Remove the battery, clean the contacts with isopropyl alcohol, and reinsert the cell. Ensure the door clicks into place; a loose door can cause a short that triggers the warning. If the icon persists, replace the battery with a fresh CR2032 and reset the unit by holding Menu for 3 seconds. Another frequent issue is the HVAC not turning on during the scheduled times. Check that the HVAC Mode is set to Auto and that the Run Schedule toggle is enabled. The Reddit thread “Pro1 Thermostat (T705). How do i turn OFF run schedule?” indicates that users sometimes inadvertently disable the run schedule. Re‑enable it by selecting Run Schedule in the Tech menu and confirming the change. After enabling, the unit will resume honoring the schedule. If the thermostat’s display goes blank or shows “Error”, perform a hard reset: disconnect the power, wait 30 seconds, reconnect, and hold Up while powering on. This clears cached settings and may resolve minor glitches. For persistent errors, consult the error code list in the manual and compare with the displayed code. Contact Pro1 support if the code is not listed. Finally, verify that the thermostat’s time is correct. An incorrect system clock can cause the schedule to shift. Set the time manually via Settings > Time or enable Auto‑Sync if the unit is connected to a network. A correct clock ensures that the 7d schedule aligns with real‑world times and that the HVAC operates as intended. If the HVAC still does not respond, check the wiring to the thermostat; Loose connections can prevent the unit from receiving the signal to activate. Use a multimeter to verify continuity between the thermostat terminals and the HVAC control board. If continuity is lost, tighten the screws or replace the connector. When the thermostat shows a blinking icon, it indicates a communication error with the HVAC system. Reset the HVAC control board by turning the main breaker off for 30 seconds, then back on. This can clear transient faults. For advanced troubleshooting, enable diagnostic mode by holding the Down button while powering on. The screen will display voltage, temperature, and error codes. This information can be shared with support to expedite resolution. Always keep the firmware up to date to avoid known bugs.

Firmware Updates

Updating the T705’s firmware is essential for unlocking the full 7‑day schedule, resolving known bugs, and adding new features. The official Pro1 website hosts the latest binary files and a simple USB flashing tool. First, download the Pro1_T705_Firmware_vX.Y.Z.bin file from the firmware download page. Next, connect the thermostat to a computer using the supplied USB cable. Launch the flashing utility, select the downloaded .bin file, and click “Flash”. The unit will reboot automatically and the screen will display a progress bar. After the update, navigate to Settings > Firmware to confirm the new version. If the 7d schedule still does not appear, the unit may be a 5d variant; contact support for a hardware confirmation. For safety, keep the thermostat powered during the update and avoid unplugging it. A failed update will trigger a “Recovery Mode” screen; to recover, re‑flash the same binary or use the recovery firmware package. Users have reported that the 7d mode appears only after a firmware upgrade, so keeping the firmware current is recommended. If you encounter error codes during flashing, consult the error code guide or reach out to Pro1 support. Firmware updates can also improve battery life and communication reliability with the HVAC system. For future firmware releases, Pro1 recommends checking the release notes on their website for new features, bug fixes, and compatibility updates!!!
