Observe the display to confirm the new setpoint before allowing the system to adjust․
Operating Modes: Heat, Cool, Auto, Off
The Model T705 offers four primary operating modes: Heat, Cool, Auto, and Off․ Heat mode activates the heating system when the temperature falls below the setpoint․ Cool mode activates the cooling system when the temperature rises above the setpoint․
Auto mode intelligently switches between heating and cooling to maintain your desired temperature․ Off mode disables both heating and cooling systems, conserving energy․
To select a mode, use the ‘Mode’ button on the thermostat; each press cycles through the available options․ The currently selected mode is indicated by an icon on the display․
Heat Mode Details
In Heat mode, the Model T705 prioritizes maintaining the set temperature by activating your heating system․ The thermostat monitors the room temperature and turns the heat on when it drops below the setpoint by a defined differential (typically 1°F)․
You can adjust the set temperature using the up and down arrow buttons․ The display will show the current room temperature and the desired setpoint․
The heating system will continue to run until the room temperature reaches the setpoint, then cycle off․ Ensure your heating system is functioning correctly for optimal performance in Heat mode․
Cool Mode Details
In Cool mode, the Model T705 activates your cooling system to maintain the desired temperature․ The thermostat compares the room temperature to your setpoint and initiates cooling when the room temperature exceeds the setpoint plus a defined differential (typically 1°F)․
Adjust the set temperature using the up and down arrow buttons; the display shows current and desired temperatures․
The cooling system operates until the room temperature reaches the setpoint, then cycles off․ Verify your cooling system is operational for effective cooling in Cool mode․
Auto Mode Functionality
Auto mode intelligently switches between heating and cooling to maintain your desired comfort level․ You set both a heating and cooling setpoint․ The Model T705 automatically determines which system to activate based on the room temperature and these setpoints․
If the room temperature falls below the heating setpoint, heating activates․ Conversely, if it rises above the cooling setpoint, cooling activates․
This mode is ideal for climates with fluctuating temperatures, providing consistent comfort without manual adjustments․ Ensure both heating and cooling systems are functional for optimal Auto mode performance․
Programming Schedules
Scheduling allows you to pre-set temperature changes throughout the day, optimizing comfort and saving energy․ The Model T705 supports both daily and 7-day schedules, catering to varied lifestyles․ You can define multiple periods within each day, each with a specific temperature setting․
