Thermostat Operation Overview
The Pro1 T705 thermostat offers user-friendly control over your home’s heating and cooling systems. Core functionality revolves around programming a schedule to optimize energy usage and comfort. The thermostat supports both 7-day and 5-1-1 day programming options, allowing customization to fit diverse lifestyles. Users can define distinct periods – Wake, Leave, Return, and Sleep – with specific temperature settings for each.
Basic Operation: The T705 allows manual temperature adjustments overriding the programmed schedule. It clearly displays the current time, date, and set temperature. Switching between heating and cooling modes is straightforward, ensuring year-round climate control. The thermostat’s intuitive interface simplifies navigation through menus and settings.

Understanding the interaction between programmed schedules and manual overrides is crucial for efficient operation. Regular review of the schedule and temperature swing settings will maximize energy savings. The unit’s display provides clear feedback on the current operating mode and programmed settings.

Setting the Current Time and Date
Accurate time and date settings are fundamental for proper schedule operation of the Pro1 T705 thermostat; To begin, access the settings menu, typically through a dedicated “Menu” or “Settings” button on the thermostat’s faceplate. Navigate to the “Time & Date” option using the up and down arrow keys.
Adjusting the Time: Once selected, the hour display will flash. Use the arrow keys to increment or decrement the hour. Press the “Select” or “Enter” button to confirm. Repeat this process for setting the minutes. Ensure AM/PM is correctly configured.
Setting the Date: After setting the time, navigate to the date setting. The month, day, and year will each require individual adjustment using the arrow keys and confirmation with the “Select” button. Double-check all entries for accuracy. Proper time and date ensure your programmed schedule aligns with your daily routine, maximizing energy efficiency and comfort.
Programming the Schedule: 5-1-1 Day vs. 7 Day
The Pro1 T705 offers two scheduling options: 5-1-1 Day and 7 Day. The 5-1-1 Day schedule differentiates between weekdays (Monday-Friday), Saturday, and Sunday. This is ideal for routines consistent across the workweek with different weekend settings. You program one schedule for the five weekdays, one for Saturday, and one for Sunday.
The 7 Day schedule allows for unique programming for each day of the week. This is best suited for highly variable routines where each day demands a distinct temperature profile. Selecting 7 Day requires programming seven individual schedules, offering maximum customization.
To choose, access the “Schedule” menu and select your preferred option. The thermostat will then guide you through setting “Wake,” “Leave,” “Return,” and “Sleep” periods for each selected day or day type, defining temperature settings for each period. Consider your lifestyle when choosing the most efficient scheduling method.
Understanding Wake, Leave, Return, and Sleep Periods
The Pro1 T705 utilizes four key periods within its programmable schedule: Wake, Leave, Return, and Sleep. Wake sets the temperature for when you typically rise in the morning, providing comfort upon waking. Leave adjusts the temperature for when the home is unoccupied during the day, conserving energy while you’re away.
Return sets the temperature for when you come home, ensuring a comfortable environment upon your arrival. Sleep lowers the temperature overnight for energy savings and optimal sleeping conditions. Each period allows you to define both a start time and a desired temperature.
Customizing these periods is crucial for maximizing comfort and efficiency. Consider your daily routine when setting times. For example, if you leave for work at 8:00 AM, set the “Leave” period to begin at that time. Experiment with temperatures to find the balance between comfort and energy savings for each period.
Configuring Heating and Cooling Modes
The Pro1 T705 thermostat offers independent control for heating and cooling systems. You can select “Heat,” “Cool,” “Off,” or “Auto” modes. In “Heat” mode, the thermostat activates the heating system when the temperature falls below the setpoint. Conversely, “Cool” mode activates the cooling system when the temperature rises above the setpoint.
“Off” disables both heating and cooling, while “Auto” intelligently switches between heating and cooling to maintain the desired temperature. When using “Auto,” you must set both a heating and cooling setpoint. The thermostat determines which system to activate based on the current temperature and these setpoints.
To configure these modes, navigate to the system settings within the thermostat’s menu. Ensure the correct mode is selected based on the season and your comfort preferences. Properly configuring these modes is essential for efficient operation and maintaining a comfortable indoor climate throughout the year.
Adjusting Temperature Swing Settings
The temperature swing, also known as differential, determines how much the temperature can deviate from the setpoint before the heating or cooling system activates. A smaller swing (e.g., 1°F) results in more frequent, but smaller, adjustments, maintaining a consistent temperature. A larger swing (e.g., 3°F) leads to less frequent, but larger, adjustments, potentially saving energy.
The Pro1 T705 allows you to independently adjust the temperature swing for both heating and cooling modes. Access the swing settings through the thermostat’s menu. Consider your comfort level and energy-saving goals when setting the swing. A wider swing can reduce energy consumption, but may result in noticeable temperature fluctuations.
Experiment with different swing settings to find the optimal balance between comfort and efficiency for your home. Remember to monitor your energy bills and adjust accordingly. Proper swing configuration contributes significantly to the thermostat’s overall performance and energy management capabilities.
Battery Replacement and Maintenance
The Pro1 T705 thermostat utilizes batteries as a power source or as backup during power outages. Low battery indicators will appear on the display, signaling the need for replacement. Typically, two AA alkaline batteries are required. Ensure you use fresh, high-quality batteries for optimal performance and longevity.

To replace the batteries, locate the battery compartment – often easily accessible on the front or side of the unit. Carefully remove the old batteries and insert the new ones, observing the correct polarity (+ and -). The thermostat may briefly reset upon battery replacement, requiring you to re-check the time and date.
Regular maintenance involves gently cleaning the thermostat’s exterior with a soft, dry cloth. Avoid using liquids or abrasive cleaners. Periodically check the battery compartment for corrosion. Proper battery maintenance ensures reliable operation and extends the lifespan of your Pro1 T705 thermostat.
