This document describes the Honeywell Wi-Fi Touchscreen Programmable Thermostat, Model RTH8580WF, a device designed for remotely monitoring and controlling heating and cooling systems. It offers a user-friendly touchscreen interface and connectivity to Honeywell's Total Connect Comfort Solutions, allowing users to manage their home or business comfort system from anywhere.

Function Description

The Honeywell RTH8580WF thermostat allows users to:

Connect to the Internet: Monitor and control heating/cooling systems remotely via a laptop, tablet, or smartphone.
View and Change Settings: Adjust heating/cooling system settings from anywhere.
Set Temperature and Schedules: Program temperature settings and schedules for optimal comfort and energy savings.
Receive Alerts and Automatic Upgrades: Get email notifications and automatic software updates for the thermostat.

The thermostat is pre-programmed with energy-saving schedules for four time periods (WAKE, LEAVE, RETURN, SLEEP), which can reduce heating/cooling expenses by up to 33% when used as directed. These schedules are fully customizable.

Important Technical Specifications

Power Requirements: Operates on 24-volt systems. It is NOT compatible with 120/240 volt systems. A "C" (common) wire is required for operation, providing 24 VAC power. Older mechanical or battery-operated thermostats may not have a C wire, and installation of a new C wire might be necessary.
Battery: Includes a coin cell battery (inside the back of the thermostat) for internal clock and settings retention during power outages.
Wi-Fi Connectivity: Connects to a home wireless network for remote access and control.
System Compatibility: Supports various heating/cooling system types, including:
- Conventional single-stage, multistage heat and cool systems (natural gas, oil, or electric furnace, air conditioner).
- Heat pump systems (with or without backup/auxiliary heat).
- Heat only systems (with or without fan).
- Cool only systems.
Temperature Range: Allows setting of both heat and cool temperatures. For auto changeover, heat and cool settings must be at least 3 degrees apart.
Display: Touchscreen display with a message center for Wi-Fi connection and registration status, MAC ID, and MAC CRC. The screen is typically lit at low intensity and brightens when touched.
MAC ID and MAC CRC: Alphanumeric codes unique to each thermostat, essential for online registration. These are found on the Thermostat ID Card and in the message center.

Usage Features

Installation Process:
1. Switch OFF Power: Crucial for equipment protection.
2. Remove Old Thermostat: Leave wallplate and wiring in place, and take a picture of the wiring for reference. Proper disposal instructions are provided for older thermostats containing mercury.
3. Label Wires: Use supplied sticky tags to label wires according to old terminal designations, not wire color.
4. Remove Wallplate: Separate the new Wi-Fi thermostat from its wallplate.
5. Mount Wallplate: Secure the new wallplate using screws and anchors.
6. Connect Wires: Match labeled wires to the new thermostat's terminals. Specific wiring instructions are provided for conventional and heat pump systems, including alternate wiring keys for non-matching labels. A C wire is mandatory.
7. Install Battery: Insert the coin cell battery, observing correct polarity.
8. Attach Thermostat: Align and snap the thermostat onto the wallplate.
9. Switch ON Power: Restore power to the heating/cooling system.
10. Set Date and Time: Adjust using the touchscreen arrows.
11. Determine System Type: Configure the thermostat to match the heating/cooling system type via system settings (Function 0170).
Wi-Fi Connection and Registration:
1. Connect to Thermostat Network: On a wireless device (laptop, tablet, smartphone), connect to the thermostat's temporary Wi-Fi network (e.g., NewThermostat_123456).
2. Join Home Network: Open a web browser, access the Thermostat Wi-Fi Setup page (http://192.168.1.1 if not automatic), find and connect to the home network, and enter the password if required.
3. Verify Connection: The thermostat message center will display "CONNECTING..." followed by "CONNECTION SUCCESSFUL" and "YOU ARE ALMOST DONE!".
4. Register Online: Create an account or log in at mytotalconnectcomfort.com. Register the thermostat by entering its MAC ID and MAC CRC.
5. Remote Control: Once registered, the thermostat can be controlled remotely via the Total Connect Comfort website or mobile app (available for Apple iPhone, iPad, iPod touch, and Android devices).
Operation Modes:
- Fan Operation: Select ON (fan always on) or AUTO (fan runs only when heating/cooling system is on).
- System Mode: Choose HEAT, COOL, OFF, AUTO (automatically selects heating or cooling based on indoor temperature), or EM HEAT (heat pumps with auxiliary heat).
Scheduling:
- Adjust Program Schedules: Press SCHED, then EDIT. Select days, then set Wake, Leave, Return, and Sleep times and temperatures for Heat and Cool. Unwanted periods can be canceled.
- Temporary Override: On the home screen, adjust the temperature. The new setting is maintained until the "Hold Until" time expires, then the schedule resumes. Can be canceled manually.
- Permanent Override: Press HOLD to permanently adjust the temperature, turning off the program schedule. The setting remains until manually changed or canceled.
- Vacation Hold: Suspend the program schedule for an extended period by setting a temperature and the number of days.
Special Features:
- Smart Response Technology: The thermostat "learns" how long it takes to reach programmed temperature settings, ensuring the desired temperature is achieved at the set time (e.g., reaches 70° by 6:00 am).
- Compressor Protection: Forces a delay before restarting the compressor to prevent equipment damage. A "Wait" message is displayed during this time.
- Heat/Cool Auto Changeover: Automatically switches between heating and cooling modes based on indoor temperature, common in climates where both are used daily. Requires a minimum 3°F difference between heat and cool settings.

Maintenance Features

Cleaning the Screen: Press SCREEN to lock the screen for 30 seconds for cleaning. Spray liquid onto a damp cloth (water or household glass cleaner), not directly onto the thermostat. Avoid abrasive cleansers.
Filter Change Reminder: If activated during installation, a message alerts when it's time to replace the filter. Press RESET after changing the filter to restart the timer. The reminder interval can be adjusted in system settings (Function 0500).
System Setup and Options: Access system functions (designated by four-digit numbers) by pressing SYSTEM and holding the center blank button. These allow customization of various settings, including:
- Device Name (0112)
- Year/Month/Date Setting (0120, 0130, 0140, 0150)
- Schedule Options (0160)
