Why is my RTH6500WF Smart Series Programmable Thermostat not following my

schedule?

Your thermostat is equipped with the Adaptive Recovery feature, which allows the thermostat to “learn” how long it takes to reach a desired setpoint and begin heating or cooling earlier than your scheduled start time. To disable this feature, go to use the User Guide to access the Installer Setup.

Other causes can include incorrect time setting on the thermostat, or if connected to WiFi and registered, incorrect zip code being listed under the location settings. Only available to modify from the My Total Connect Comfort web portal – not currently supported in the mobile app

Why is my RTH6500WF Smart Series Programmable Thermostat set to Heating,

but I feel Cool or Mild Air and not heat? (Or Why is my thermostat set to Cooling but I feel Heat or Mild air and not cooling?)

Check your wire.

  • If you have a wire in either the R or RC terminal and no wire in the other terminal (R or RC), insert the jumper wire. If you have a wire in the R terminal and a wire in the RC terminal, remove the jumper wire. One wire? Jumper goes in. Two Wires? Take the jumper out.
  • If you have a wire in the RC terminal and no wire in the R terminal, insert the jumper wire. If you have a wire in the R terminal and a wire in the Rc terminal, remove the jumper wire.

Check your configuration (referred to as the ISU [Installer Set Up]) using the user manual or installer manual.

  • Verify you have entered the correct System Type. For Heat pump systems, most commonly, O/B is energized in Cooling (O on cool). For Rheem or Ruud brand heat pumps, the O/B must energize on heating (B on Heat).

Why won’t my RTH6500WF Smart Series Programmable Thermostat screen power

up?

The thermostat operates between 20-30 VAC, “supplied” to the R/RC terminals and “returning” through the C terminal. A C wire, connected to C on the equipment, is required for the thermostat to power itself.

Verify the furnace / air handler door is closed, the power switch is on, and the breakers are on.

Confirm you have a C wire in the C terminal. If your previous thermostat did not use a C wire, it’s unlikely that it is connected at the equipment. Verify the C wire is connected to the C terminal in your furnace or air handler.

Check your jumper wire. If you have a wire in the R terminal and no wire in the RC terminal, verify the jumper wire is inserted between the R and Rc terminals. If you have a wire in the R terminal and a wire in the Rc terminal, the jumper wire will be removed. Advanced steps:

Using a multimeter, measure the AC voltage between your R/ RC wire and your C wire. Your thermostat operates between 20-30VAC, any reading outside this range should be addressed by a Professional Contractor.

Why is my RTH6500WF Smart Series Programmable Thermostat not connecting to

my WiFi?

If you are unable to complete the WiFi connection process, attempt the following before proceeding:

Attempt to connect and register the thermostat to a mobile hotspot. This allows the registration data to bypass any network security that may be causing the connection failure. Once successfully registered, a Wi-Fi Reset can be performed to move the thermostat to the home Wi-Fi network.

Wi-Fi Network Recommendations:

If you experience inability to connect, failure to register, or frequent Wi-Fi signal loss, verify the following:

You may need assistance from your Internet Service Provider to verify/ change some settings

2.4GHz bandwidth Network only (Simultaneous 2.4/5GHz networks that experience connectivity failure may require a separate dedicated 2.4 GHz network to be calibrated)

Connect directly to the router signal – Not recommended for use with signal booster, satellites, or extenders.

Business Networks (Enterprise networks, guest networks, or networks that require logging in via a web page/portal) are not supported.

Gateways or Network switches can blocksome communications and are not supported.

Recommended WPA2-AES Network Security Protocol DHCP Enabled – Static networks not supported

UPnP / P2P Enabled Band-Steering Disabled

Why is my Cooling not Working on my RTH6500WF Smart Series Programmable

Thermostat?

Your primary cooling (1st stage) is controlled by the Y terminal on your thermostat. (Or the Y and O/B terminal if you have a heat pump system) In addition, the G terminal is activated to turn on the fan in your home to circulate the cooler air.

Confirm the furnace / air handler door is closed and turned on. Check the circuit breaker to your equipment.

Confirm the thermostat is set to Cool mode and the setpoint (the smaller number at the top of the thermostat display), is set to a temperature lower than the display temp (the larger number in the center of the display).

Confirm the message “Cool On” is solid (not flashing) on the thermostat display.

Confirm your wiring is correct, and the wires have good contact in the terminals (tug gently on the wires)

Advanced steps:

Using a multimeter, measure the AC voltage between your Rc wire and your Y wire. Your thermostat operates between 20-30VAC, any reading outside this range should be addressed by a Professional Contractor.

Why is my Heating not Working on my RTH6500WF Smart Series Programmable

Thermostat?

Your primary heating (1st stage) is controlled by the W terminal on your thermostat. (Or the Y and O/B terminal if you have a heat pump system)

Confirm the thermostat is set to Heat mode and the setpoint is set to a temperature higher than the display temperature.

Confirm the message “Heat On” is solid (not flashing) on the thermostat display.

Confirm your wiring is correct, and the wires have good contact in the terminals (tug gently on the wires)

Check your jumper wire. To operate heating, the thermostat requires power to the R terminal. (If you have a wire in the RC terminal and no wire in the R terminal, insert the jumper wire between the R and Rc terminals)

Advanced steps: Using a multimeter, measure the AC voltage between your R wire and your W wire (between Rc and Y for heat pump systems). Your thermostat operates between 20-30VAC, any reading outside this range should be addressed by a Professional Contractor.

What are the features on my RTH6500WF Smart Series Programmable

Thermostat?

A complete list of all features and functions is available for the RTH6580WF1 in the User Guide here (or TH6320WF1 Install Guide here). We’ve outlined a few of the common features below:

  • Hold
  • Scheduling
  • Smart Response
  • Clock
  • Temperature Scale
  • Auto Changeover
  • Reset

Hold:
When using a schedule, the thermostat enables the Hold feature. Two types of Holds are available, Temporary and Permanent.
Adjust the temperature setting on your thermostat display. A “HOLD UNTIL” message will appear, followed by the time of the next schedule change. Press the HOLD button to enable Permanent Hold, which will keep the new temperature indefinitely. Press the Cancel button to remove the Hold status.

Schedule:

The user guide has detailed steps on using the schedule for your thermostat. Click here to access the RTH6580WF1 user guide (the process is the same for the TH6320WF1).

Smart Response Technology:  (also referred to as Smart Recovery, Smart Start, and Adaptive Intelligent Recovery)

The thermostat has the option to begin your schedule setting changes early in order to reach your desired temperature at the start of the schedule period. When active, the thermostat “learns” how long it takes to reach setpoint within your home, and starts heating or cooling early. (ex. “My home is 65° at night, but set to 70° at 7:00a.m.” Rather than waiting until 7:00a.m. to start warming up, Recovery begins Heating the home early [based on its algorithm and learned behavior] and starts heating the home at 6:00a.m., reaching the 70° setting by 7:00a.m.)

Clock:

When connected to Wi-Fi, the thermostat displays the local time based on the account creators Zip Code (as related to Time Zone). When not connected to Wi- Fi, the clock can be configured on the thermostat display when powered up.

Temp Scale:

You can adjust the temperature display settings at any time. Display temperatures are available in Fahrenheit or Celsius

Auto Changeover:

The changeover feature (also referred to as Changeover) allows your thermostat to automatically switch from heating to cooling, or vice versa, depending on the temperature in your home. The thermostat has a mandatory 1.5° differential or “swing”, so even if you set your thermostat heating temp to 70° and the cooling temp to 70° and turn changeover on, the temperature must rise or fall at least 1.5° before the thermostat will switch modes. (For the previous example, the temperature would have to climb to 71.5 degrees)

Reset:

The thermostat has 2 reset options: Factory or Schedule

Restore Original Settings (Factory Reset): clears all of the thermostats programming and resets it to factory defaults

*Prior to performing a Factory Reset, we recommend recording your current ISU configuration (see Setup and Configuration)

Schedule reset: clears the schedule and resets it to the daily default schedule listed below:

Wake   6:00a.m. Cool 78   Heat 70
Away   8:00a.m. Cool 85   Heat 62
Home   6:00p.m. Cool 78   Heat 70
Sleep   10:00p.m. Cool 82   Heat 62

How do I configure my RTH6500WF Smart Series Programmable Thermostat?

When configuring your thermostat, it is important to configure it correctly for your system type. Incorrectly configuring your thermostat can lead to inefficient operation and in extreme cases, damage to your system

When first installed and powered on, the thermostat will guide you through the initial configuration. You will require the user manual to navigate the numbered settings. Click here for a digital copy for the RTH6580WF1, click here for a digital copy for the TH6320WF1.

Configuring during initial setup:

When powered, after setting the time and date, the thermostat will display 2 sets of numbers, one set on the left of the display and one set on the right. Use the User Guide to configure your thermostat for your system. After finishing the setup, the thermostat will control your heating and cooling system normally.

Wi-Fi – After installing your thermostat, Wi-Fi Setup will display on your thermostat screen. This indicator means your thermostat is broadcasting it’s own Wi-Fi network and is ready to be paired.

How do I wire my RTH6500WF Smart Series Programmable Thermostat?

The thermostat uses 1 wire to control each of your HVAC system’s primary functions, such as heating, cooling, fan, etc. See the diagram below for what each wire controls on your system:

Y – Compressor Stage 1 (Cooling)
Y2 – Compressor Stage 2 (Cooling)
G – Fan
C – Common
L/A – A – Input for heat pump fault
W -O/B – Heat Stage 1 (Heating) / Reversing valve for Heat Pump systems
W2 -Aux/E – Heat Stage 2 (Heating) / Backup Heat
R – 24vac (Heating transformer)
Rc – 24vac (Cooling transformer)

at its most basic, your thermostat connects terminals via internal relays to send power to these different wires to control your HVAC system. For instance, for a gas furnace to turn on the heat, the thermostat internally connects the R terminal (power) to the W terminal (heat stage 1) to turn on the furnace.

Look at the list of wiring configurations by system type below. Your wiring will match one of the options below. If you do not see your wiring listed, we recommend using our on-line compatibility checker.

How do I connect my RTH6500WF Smart Series Programmable Thermostat to WiFi

and register it?

Connecting your thermostat to Wi-Fi can be performed during the initial setup and configuration, or later at a time you choose.

Connecting to Wi-Fi – Initial Setup:

After the Configuration step during the initial install, you will be prompted to connect your FocusPRO Wi-Fi 6000 to your Home Wi-Fi.

The FocusPRO Wi-Fi 6000 uses a 3-step connection and registration process

Step 1 – Connect your mobile device to the thermostat’s Wi-Fi network (NewThermostatxxxxxx)

Step 2 – Connect the thermostat to your home Wi-Fi (via an internet browser on your mobile device)

Step 3 – Register your thermostat in the My Total Connect Comfort web portal.

Registration cannot be performed with the mobile app, currently only supported via the web portal

Step 1 – Connecting your mobile device to the thermostat’s Wi-Fi network (NewThermostatxxxxxx)

Once installed and configured, the thermostat will display “Wi-Fi Setup”. Open the Settings – Wi-Fi on your mobile device and connect to the Wi-Fi network named “NewThermostatxxxxxx”.

If your thermostat does not display Wi-Fi Setup, remove the thermostat faceplate from the wall plate for 30 seconds and then reattach it. If Wi-Fi setup does not display, enter the Installer Setup (press and hold the fan and up arrow simultaneously for 5-10 seconds until the screen changes) and use the RTH6580WF1 User Guide here (or TH6320WF1 Install Guide here) to navigate the settings to function 38. Make sure function 38 is set to 1, then proceed to function 39. Use the up or down arrow to change function 39 function to 0 then press done. WiFi setup will then be displayed on the screen. Return to step 1.

Step 2 – Connect the thermostat to your home Wi-Fi (via an internet browser on your mobile device)

After connecting to the thermostat Wi-Fi (NewThermostatxxxxxx), open a web browser (Safari, Chrome, etc.) You should be automatically guided to a page titled “Thermostat Wi-Fi Setup. If you are not automatically guided there, enter the IP address: 192.168.1.1 into the address bar on your browser to navigate there manually.

I connect to the NewThermostatxxxxxx network, but can’t get to the “Thermostat Wi-Fi Setup” page:

The best indicator that your phone will not stay connected directly to the thermostat is when you open the web browser, you see your default browser page or the last site you visited instead of being directed to the Thermostat WiFi Setup page. Or, when entering 192.168.1.1 you see search results instead of being brought to the correct page.

*Smart phones will typically switch to another network or mobile data if the current Wi-Fi network cannot access the internet. For this step, since the thermostat network (NewThermostatxxxxxx) cannot access the internet, it is common to receive a pop-up notification that states, “Your phone is not connected to the internet.” This is normal and can be disregarded. To ensure your mobile device remains connected to the thermostat until the connection process is complete, it may be necessary to “forget” other available Wi-Fi networks, and/or to turn on Airplane Mode, until the thermostat is successfully connected. You can also temporarily disable this feature (sometimes referred to as Auto Network Switch, or Smart Switch) from the Menu- Settings on your mobile device.

You should see your Home Wi-Fi network listed. Select it and enter your Wi-Fi password. After a brief connection period, your thermostat will display a “Connection Success” message. Reconnect your phone to your home wi-Fi network if your device does not reconnect automatically

*If you do not see your home Wi-Fi network, refresh the list. Even though Wi-Fi networks are typically listed by the strongest signal, you may need to scroll through the entire list to locate yours.

Step 3 – Register athttps://www.mytotalconnectcomfort.com/portal

Registration is completed at mytotalconnectcomfort.com/portal. Navigate to the page and create an account / login. You will be prompted to create a “Location” to associate your thermostat with, if you do not have a location already in your account.

Select the “Add Device” icon and Input the MAC ID / CRC for your device. (MAC ID / CRC are located on your thermostat information card, on the back of the thermostat.

Complete the security check (if prompted) and follow the directions within the web portal to complete the registration.

Unable to Register:

If your device connects to Wi-Fi, but fails to register, it may already be registered to another user. If known, contact the previous owner and ask that they delete the device from their account. If the previous owner is not known, contact Resideo Customer Care to unregister your device. You will require the MAC ID (located on the back of your product) to complete the un-registration process.

Wi-Fi Reset:

A basic Wi-Fi Reset can be performed by removing the thermostat face plate from the wall plate and reattaching it after 30 seconds. The thermostat will attempt to connect to the Wi-Fi signal is was previously paired with. To connect to a new Wi-Fi signal, follow step 1 outlined above to disconnect or “forget” the old Wi-Fi network and connect to the new network.

How do I wire my RTH6500WF Smart Series Programmable Thermostat?

The thermostat uses 1 wire to control each of your HVAC system’s primary functions, such as heating, cooling, fan, etc. See the diagram below for what each wire controls on your system:

Y – Compressor Stage 1 (Cooling)
Y2 – Compressor Stage 2 (Cooling)
G – Fan
C – Common
L/A – A – Input for heat pump fault
W -O/B – Heat Stage 1 (Heating) / Reversing valve for Heat Pump systems
W2 -Aux/E – Heat Stage 2 (Heating) / Backup Heat
R – 24vac (Heating transformer)
Rc – 24vac (Cooling transformer)

at its most basic, your thermostat connects terminals via internal relays to send power to these different wires to control your HVAC system. For instance, for a gas furnace to turn on the heat, the thermostat internally connects the R terminal (power) to the W terminal (heat stage 1) to turn on the furnace.

Why is my Heating not Working on my RTH6500WF Smart Series Programmable

Thermostat?

Your primary heating (1st stage) is controlled by the W terminal on your thermostat. (Or the Y and O/B terminal if you have a heat pump system)

Confirm the thermostat is set to Heat mode and the setpoint is set to a temperature higher than the display temperature.

Confirm the message “Heat On” is solid (not flashing) on the thermostat display.

Confirm your wiring is correct, and the wires have good contact in the terminals (tug gently on the wires)

Check your jumper wire. To operate heating, the thermostat requires power to the R terminal. (If you have a wire in the RC terminal and no wire in the R terminal, insert the jumper wire between the R and Rc terminals)

Advanced steps: Using a multimeter, measure the AC voltage between your R wire and your W wire (between Rc and Y for heat pump systems). Your thermostat operates between 20-30VAC, any reading outside this range should be addressed by a Professional Contractor.

Why is my RTH6500WF Smart Series Programmable Thermostat set to Heating,

but I feel Cool or Mild Air and not heat? (Or Why is my thermostat set to Cooling but I feel Heat or Mild air and not cooling?)

Check your wire.

  • If you have a wire in either the R or RC terminal and no wire in the other terminal (R or RC), insert the jumper wire. If you have a wire in the R terminal and a wire in the RC terminal, remove the jumper wire. One wire? Jumper goes in. Two Wires? Take the jumper out.
  • If you have a wire in the RC terminal and no wire in the R terminal, insert the jumper wire. If you have a wire in the R terminal and a wire in the Rc terminal, remove the jumper wire.

Check your configuration (referred to as the ISU [Installer Set Up]) using the user manual or installer manual.

  • Verify you have entered the correct System Type. For Heat pump systems, most commonly, O/B is energized in Cooling (O on cool). For Rheem or Ruud brand heat pumps, the O/B must energize on heating (B on Heat).

Share:

A complete list of all features and functions is available for the RTH6580WF1 in the User Guide here (or TH6320WF1 Install Guide here). We’ve outlined a few of the common features below:

  • Hold
  • Scheduling
  • Smart Response
  • Clock
  • Temperature Scale
  • Auto Changeover
  • Reset

Hold:
When using a schedule, the thermostat enables the Hold feature. Two types of Holds are available, Temporary and Permanent.
Adjust the temperature setting on your thermostat display. A “HOLD UNTIL” message will appear, followed by the time of the next schedule change. Press the HOLD button to enable Permanent Hold, which will keep the new temperature indefinitely. Press the Cancel button to remove the Hold status.

Schedule:

The user guide has detailed steps on using the schedule for your thermostat. Click here to access the RTH6580WF1 user guide (the process is the same for the TH6320WF1).

Smart Response Technology:  (also referred to as Smart Recovery, Smart Start, and Adaptive Intelligent Recovery)

The thermostat has the option to begin your schedule setting changes early in order to reach your desired temperature at the start of the schedule period. When active, the thermostat “learns” how long it takes to reach setpoint within your home, and starts heating or cooling early. (ex. “My home is 65° at night, but set to 70° at 7:00a.m.” Rather than waiting until 7:00a.m. to start warming up, Recovery begins Heating the home early [based on its algorithm and learned behavior] and starts heating the home at 6:00a.m., reaching the 70° setting by 7:00a.m.)

Clock:

When connected to Wi-Fi, the thermostat displays the local time based on the account creators Zip Code (as related to Time Zone). When not connected to Wi- Fi, the clock can be configured on the thermostat display when powered up.

Temp Scale:

You can adjust the temperature display settings at any time. Display temperatures are available in Fahrenheit or Celsius

Auto Changeover:

The changeover feature (also referred to as Changeover) allows your thermostat to automatically switch from heating to cooling, or vice versa, depending on the temperature in your home. The thermostat has a mandatory 1.5° differential or “swing”, so even if you set your thermostat heating temp to 70° and the cooling temp to 70° and turn changeover on, the temperature must rise or fall at least 1.5° before the thermostat will switch modes. (For the previous example, the temperature would have to climb to 71.5 degrees)

Reset:

The thermostat has 2 reset options: Factory or Schedule

Restore Original Settings (Factory Reset): clears all of the thermostats programming and resets it to factory defaults

*Prior to performing a Factory Reset, we recommend recording your current ISU configuration (see Setup and Configuration)

Schedule reset: clears the schedule and resets it to the daily default schedule listed below:

Wake   6:00a.m. Cool 78   Heat 70
Away   8:00a.m. Cool 85   Heat 62
Home   6:00p.m. Cool 78   Heat 70
Sleep   10:00p.m. Cool 82   Heat 62

Why is my Cooling not Working on my RTH6500WF Smart Series Programmable

Thermostat?

Your primary cooling (1st stage) is controlled by the Y terminal on your thermostat. (Or the Y and O/B terminal if you have a heat pump system) In addition, the G terminal is activated to turn on the fan in your home to circulate the cooler air.

Confirm the furnace / air handler door is closed and turned on. Check the circuit breaker to your equipment.

Confirm the thermostat is set to Cool mode and the setpoint (the smaller number at the top of the thermostat display), is set to a temperature lower than the display temp (the larger number in the center of the display).

Confirm the message “Cool On” is solid (not flashing) on the thermostat display.

Confirm your wiring is correct, and the wires have good contact in the terminals (tug gently on the wires)

Advanced steps:

Using a multimeter, measure the AC voltage between your Rc wire and your Y wire. Your thermostat operates between 20-30VAC, any reading outside this range should be addressed by a Professional Contractor.

Why won’t my RTH6500WF Smart Series Programmable Thermostat screen power

up?

The thermostat operates between 20-30 VAC, “supplied” to the R/RC terminals and “returning” through the C terminal. A C wire, connected to C on the equipment, is required for the thermostat to power itself.

Verify the furnace / air handler door is closed, the power switch is on, and the breakers are on.

Confirm you have a C wire in the C terminal. If your previous thermostat did not use a C wire, it’s unlikely that it is connected at the equipment. Verify the C wire is connected to the C terminal in your furnace or air handler.

Check your jumper wire. If you have a wire in the R terminal and no wire in the RC terminal, verify the jumper wire is inserted between the R and Rc terminals. If you have a wire in the R terminal and a wire in the Rc terminal, the jumper wire will be removed.Advanced steps:

Using a multimeter, measure the AC voltage between your R/ RC wire and your C wire. Your thermostat operates between 20-30VAC, any reading outside this range should be addressed by a Professional Contractor.

Why is my RTH6500WF Smart Series Programmable Thermostat not connecting to

my WiFi?

If you are unable to complete the WiFi connection process, attempt the following before proceeding:

Attempt to connect and register the thermostat to a mobile hotspot. This allows the registration data to bypass any network security that may be causing the connection failure. Once successfully registered, a Wi-Fi Reset can be performed to move the thermostat to the home Wi-Fi network.
