Key Features and Controls of the RTH8500
The RTH8500 thermostat boasts intuitive touchscreen controls for ease of use. Key features include quick access to settings for clock‚ fan‚ and system adjustments‚ simplifying temperature management. This programmable device offers a user-friendly interface to optimize your home’s climate.
Quick Reference to Thermostat Controls
The Honeywell RTH8500 touchscreen thermostat provides a quick reference to its primary controls through an intuitive display‚ simplifying home climate management effectively. Key adjustments for clock‚ fan‚ and system modes are all easily accessible‚ significantly enhancing daily interaction.

For clock setting‚ the touchscreen allows swift adjustment‚ ensuring precise activation of all programmed schedules for optimal comfort. The fan setting offers clear options: “Auto” runs the fan only with heating/cooling cycles‚ while “On” provides continuous airflow for consistent circulation.
Furthermore‚ the system setting is crucial for selecting the desired operational mode. Users can effortlessly switch between “Heat” for warmth‚ “Cool” for air conditioning‚ “Off” to disable‚ or “Auto” for automatic switching. These vital core controls‚ clearly presented on the responsive touchscreen‚ make the RTH8500 exceptionally user-friendly. This design minimizes complexity‚ enabling quick adjustments and immediate mastery over your home’s environmental settings without extensive manual consultation.
Setting the Thermostat Clock
Accurately setting the thermostat clock on your Honeywell RTH8500 is a fundamental step for ensuring all programmed schedules function precisely as intended. This essential control dictates the timing for your daily heating and cooling cycles‚ directly impacting both your comfort and energy savings. The RTH8500’s touchscreen interface simplifies this process‚ making it intuitive for any user.
To adjust the clock‚ typically you would access the main menu or a dedicated “Clock” button on the screen. From there‚ you can easily set the current time and day of the week using the clear up/down arrows or direct input on the display. Maintaining an accurate clock is critical because the thermostat relies on this information to activate your desired temperature settings at specific times throughout the day‚ whether it’s for waking up‚ leaving for work‚ returning home‚ or sleeping.
Without a correctly set clock‚ your custom programs will not execute efficiently‚ potentially leading to discomfort or unnecessary energy consumption. The RTH8500’s design prioritizes ease of use for this function‚ ensuring that you can quickly and confidently manage this vital aspect of your home’s climate control.
Adjusting Fan Settings
The Honeywell RTH8500 thermostat offers flexible fan settings‚ crucial for optimizing indoor air circulation and comfort. Adjusting these helps maintain desired air quality and temperature distribution throughout your home. The primary fan modes include “Auto” and “On.”
In “Auto” mode‚ the fan operates only when the heating or cooling system actively runs to reach the set temperature. This is the most energy-efficient setting‚ as the fan cycles with your HVAC system‚ preventing continuous operation. It ensures air movement only when conditioning is required‚ saving electricity.
Conversely‚ selecting the “On” mode commands the fan to run continuously‚ regardless of whether the heating or cooling system is actively engaged. This benefits air circulation‚ reducing hot or cold spots‚ and filtering air more consistently if your system has a filter. However‚ continuous fan operation consumes more electricity.
To adjust fan settings on your RTH8500‚ locate the dedicated “Fan” button or an option within the main menu on the touchscreen display. Tapping this button usually toggles between “Auto” and “On” modes‚ allowing you to select the best option for your comfort and energy needs.

Configuring System Settings
The Honeywell RTH8500 touchscreen thermostat offers various system settings to control your home’s heating and cooling. Understanding these configurations is essential for optimal comfort and energy management. The main system modes typically include Heat‚ Cool‚ Auto‚ and Off‚ accessible directly from the thermostat’s main screen.
In Heat mode‚ the thermostat will activate your heating system when the room temperature falls below your setpoint. Conversely‚ Cool mode engages the air conditioning when the temperature rises above the desired level. The Auto mode provides intelligent climate control‚ automatically switching between heating and cooling as needed to maintain a comfortable temperature range‚ minimizing manual adjustments.
Selecting Off completely deactivates your heating and cooling system‚ useful during mild weather or when you’re away for extended periods. For specific HVAC setups‚ such as heat pumps‚ an Emergency Heat (Em Heat) option might also be available. This mode bypasses the heat pump‚ using only the auxiliary or backup heating source‚ typically for extreme cold or system malfunctions.
To adjust these settings‚ simply tap the “System” button on the RTH8500’s touchscreen. Repeatedly tapping will cycle through the available modes‚ allowing you to select the appropriate operation for your current needs.

Programming Schedules for Energy Savings

Maximize energy savings with the Honeywell RTH8500 by setting customized program schedules. Tailor your heating and cooling to your daily routine‚ optimizing comfort while reducing utility costs. Efficient programming is key to smart energy management.
Creating and Modifying Program Schedules
The Honeywell RTH8500 thermostat empowers users to significantly reduce energy consumption and enhance comfort by allowing the creation and modification of detailed program schedules. This feature is central to optimizing your home’s heating and cooling. Users can set specific temperature targets for different periods throughout the day and week‚ such as ‘Wake‚’ ‘Leave‚’ ‘Return‚’ and ‘Sleep.’ For instance‚ you might program the thermostat to lower the temperature while you are away at work and then raise it just before you typically arrive home‚ ensuring a comfortable environment without wasting energy. The intuitive touchscreen interface simplifies the process of establishing these schedules‚ guiding you through setting times and desired temperatures for each day or across multiple days for consistent routines. If your routine changes‚ adjusting these programs is straightforward‚ allowing for quick modifications to adapt to new lifestyles or seasonal needs. The comprehensive operating manual provides step-by-step instructions on how to fully utilize the 7-day programming capabilities‚ ensuring you can fine-tune your climate control for maximum efficiency and personalized comfort. Taking the time to adjust your program schedules can lead to substantial savings on your utility bills over time‚ making this a valuable function of the device.

Utilizing the Vacation Hold Feature
The Honeywell RTH8500 thermostat’s Vacation Hold feature is an essential tool for energy efficiency and home protection when you are away for an extended period. This function allows you to temporarily suspend your regular program schedule and set a constant‚ energy-saving temperature. Instead of running your usual heating or cooling cycles‚ which would be wasteful when no one is home‚ Vacation Hold maintains a more moderate temperature. For example‚ you can set the thermostat to a slightly higher temperature in summer to prevent excessive heat buildup or a lower temperature in winter to protect pipes from freezing‚ all while minimizing energy consumption. Activating this feature is straightforward via the touchscreen‚ and you can typically specify the duration of the hold‚ after which the thermostat automatically reverts to your programmed schedule. This eliminates the need to remember to readjust settings upon your return‚ providing convenience and peace of mind. By intelligently managing your home’s climate during your absence‚ the Vacation Hold feature ensures you save money on utility bills while still safeguarding your home from extreme temperatures.
