Follow the on-screen instructions to complete the initial setup and personalize your comfort preferences.

Understanding the Thermostat Display

The Honeywell THM5320R features a clear, easy-to-read display providing essential information at a glance. The primary display area shows the current room temperature and the setpoint temperature. Below this, you’ll find icons indicating the current system mode – Heat, Cool, Auto, or Off. A fan icon displays the fan’s operational status: Auto or On.

A battery icon indicates the remaining battery life, alerting you when replacement is needed. The display also incorporates indicators for Redlink wireless connectivity status, showing a successful connection or prompting pairing if disconnected. During programming, the display will guide you through each step with clear prompts and options.

Additional symbols may appear to signal system issues or specific operating conditions. Refer to the troubleshooting section of this manual for detailed explanations of these indicators. Familiarizing yourself with these display elements ensures efficient operation and control of your home’s climate.

Basic Operation: Setting Temperature

To adjust the temperature with your Honeywell THM5320R thermostat, use the up and down arrow buttons located on the front panel. Pressing the ‘up’ arrow increases the setpoint temperature, while the ‘down’ arrow decreases it. The display will show the new setpoint as you adjust it. The thermostat will then automatically activate the heating or cooling system to reach and maintain the desired temperature.

The thermostat operates in either Heat or Cool mode, selectable via the ‘Mode’ button. Ensure the correct mode is selected for your desired operation. The display clearly indicates the current mode. For temporary adjustments, you can override the programmed schedule by manually setting the temperature.

The thermostat will revert to the programmed schedule at the next scheduled time. Observe the display to confirm the setpoint and system status after making adjustments. Consistent monitoring ensures optimal comfort and energy efficiency.

Fan Control Options

The Honeywell THM5320R thermostat offers several fan control options to enhance your comfort and air circulation. You can select from ‘Auto’, ‘On’, and potentially a ‘Circulate’ setting (depending on the specific model). In ‘Auto’ mode, the fan operates only during heating or cooling cycles, conserving energy. Selecting ‘On’ keeps the fan running continuously, providing consistent air movement throughout your home.

The ‘Circulate’ setting, if available, periodically runs the fan for a short duration, even when heating or cooling isn’t active, to improve air mixing and temperature distribution. To adjust the fan setting, use the designated ‘Fan’ button on the thermostat. Each press cycles through the available options, displayed clearly on the screen.

Consider your needs and preferences when choosing a fan setting. Continuous fan operation can improve air quality but may increase energy consumption. Experiment to find the optimal balance for your home.

Automatic Fan Setting

The Automatic Fan setting on your Honeywell THM5320R thermostat is designed for optimal comfort and energy efficiency. When set to ‘Auto’, the fan operates solely in conjunction with your heating or cooling system. This means the fan will turn on when the system begins a heating or cooling cycle and will turn off once the cycle completes.

This setting prevents the fan from running unnecessarily, conserving energy and reducing wear and tear on the system. Unlike the ‘On’ setting, which keeps the fan running continuously, ‘Auto’ prioritizes efficiency. It’s the recommended setting for most users, providing a comfortable environment without excessive energy usage.

To select ‘Auto’, navigate to the fan control options using the thermostat’s interface and choose the ‘Auto’ mode. The display will indicate when the fan is operating in automatic mode. This setting ensures the fan only works when needed, contributing to lower energy bills;

Programming Schedules: Time & Temperature

The Honeywell THM5320R allows for customized programming of temperature schedules, optimizing comfort and energy savings. You can set different temperatures for various times of the day, aligning with your lifestyle and occupancy patterns. This feature enables automatic adjustments, eliminating the need for manual temperature changes.

To program a schedule, access the programming mode through the thermostat’s menu. You’ll typically define periods like ‘Wake’, ‘Leave’, ‘Return’, and ‘Sleep’, assigning a specific temperature to each. The thermostat supports different schedules for weekdays and weekends, offering flexibility.

Carefully consider your daily routines when setting temperatures. Lowering the temperature while away or asleep can significantly reduce energy consumption. The THM5320R remembers your programmed schedule even during power outages, ensuring consistent comfort and savings. Review and adjust your schedule periodically to maintain optimal performance.

Redlink Wireless Compatibility

The Honeywell THM5320R thermostat boasts Redlink wireless compatibility, enabling seamless integration with other Redlink-enabled devices. This wireless technology simplifies installation and expands your home comfort control capabilities. You can connect the thermostat to remote sensors, outdoor sensors, and other compatible components without running wires.

Redlink allows for easy addition of zones, creating a more customized and efficient heating and cooling system. Remote sensors, for example, can measure temperature in specific rooms, ensuring consistent comfort throughout your home. The system utilizes a secure, reliable wireless signal, minimizing interference and ensuring accurate communication.

Expanding your Redlink system is straightforward; simply follow the pairing instructions within the thermostat’s menu. This wireless connectivity provides flexibility and convenience, allowing you to tailor your home comfort system to your specific needs and preferences.

Connecting to the Redlink System

To connect your Honeywell THM5320R to the Redlink system, begin by ensuring your Redlink equipment interface module is properly installed and powered on; On the thermostat, navigate to the menu and select the “Add Device” or “Redlink Setup” option – consult the display for precise wording. The thermostat will initiate a search for available Redlink devices.

Once the interface module appears in the list, select it to begin the pairing process. You may be prompted to enter a security code displayed on the interface module itself. Follow the on-screen instructions carefully to complete the pairing. A successful connection will be indicated by a confirmation message on the thermostat display.

Repeat this process for any additional Redlink devices you wish to connect, such as remote sensors. Refer to the documentation accompanying each Redlink device for specific pairing instructions. Proper connection ensures seamless communication and functionality within your expanded home comfort system.

Troubleshooting Common Issues

Display Not Responding: First, check the batteries. Low batteries are a frequent cause. Replace them with fresh ones. If the display remains unresponsive, attempt a thermostat reset.

Heating/Cooling Not Working: Verify the system switch is set to “Heat,” “Cool,” or “Auto” as desired. Ensure the set temperature is appropriately higher (for heat) or lower (for cool) than the current room temperature. Check your breaker box to confirm power to the HVAC system.

Redlink Connection Problems: Confirm the interface module is powered on and within range. Re-initiate the pairing process as described in the “Connecting to the Redlink System” section. Interference from other wireless devices can sometimes disrupt the signal.

Inaccurate Temperature Readings: Ensure the thermostat isn’t exposed to direct sunlight or drafts. Consider recalibrating the temperature sensor within the thermostat’s settings menu if discrepancies persist.

Low Battery Indicator & Replacement

Low Battery Warning: The Honeywell THM5320R thermostat features a low battery indicator, typically displayed as a flashing battery icon on the screen. This signifies that the batteries are nearing depletion and need replacement to ensure continued operation. Don’t ignore this warning, as it can lead to inaccurate temperature readings or complete thermostat shutdown.

Battery Type: The thermostat requires two AA alkaline batteries. Avoid using rechargeable batteries, as they may not provide sufficient voltage for optimal performance.

Replacement Procedure: Locate the battery compartment, usually on the side or back of the thermostat. Gently open the compartment and remove the old batteries.
