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.

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 wires. 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 wiring. If you have a heat pump, you may or may not have a backup heat source. (W controls your first stage of heating for Gas/Oil/Electric systems. O/B and Y control your first stage heating for heat pump systems. Backup heat sources must be connected to the W2, Aux, or E terminal for proper functionality.) If necessary, follow the wires back to your furnace or air handler and confirm the wires match the terminals on the control board.

Check your configuration. 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).

not connecting to WiFi, or losing WiFi connection frequently?

Trouble connecting?

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

Turn off mobile data. This allows the thermostat and mobile device to communicate via the same communication method and can help with the registration process.

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.

Attempt to use an alternate mobile device – some mobile devices use security features that can disrupt the registration process.

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 (Simultaneous 2.4/5GHz networks that experience connectivity failure may require a separate dedicated 2.4GHz 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 block communication and are not supported.

Recommended WPA2-AES Network Security Protocol

DHCP Enabled – Static networks not supported

UPnP / P2P Enabled

Band-Steering Disabled

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 Heating not Working on my RTH8500WF WiFi Series WiFi Touchscreen

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 heatpump systems). Your thermostat operates between 20-30VAC, any reading outside this range should be addressed by a Professional Contractor.

Why is my Cooling not Working on my RTH8500WF WiFi Series WiFi Touchscreen

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.

How do I wire my RTH8500WF WiFi Series WiFi Touchscreen Programmable

Thermostat?

Wiring Details:
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 won’t my RTH8500WF WiFi Series WiFi Touchscreen 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.

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 wires. 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 wiring. If you have a heat pump, you may or may not have a backup heat source. (W controls your first stage of heating for Gas/Oil/Electric systems. O/B and Y control your first stage heating for heat pump systems. Backup heat sources must be connected to the W2, Aux, or E terminal for proper functionality.) If necessary, follow the wires back to your furnace or air handler and confirm the wires match the terminals on the control board.

Check your configuration. 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 is my RTH8500WF WiFi Series WiFi Touchscreen Programmable Thermostat not connecting to WiFi, or losing WiFi connection frequently?

Trouble connecting?

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

Turn off mobile data. This allows the thermostat and mobile device to communicate via the same communication method and can help with the registration process.

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.

Attempt to use an alternate mobile device – some mobile devices use security features that can disrupt the registration process.

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 (Simultaneous 2.4/5GHz networks that experience connectivity failure may require a separate dedicated 2.4GHz 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 block communication 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 RTH8500WF WiFi Series WiFi Touchscreen 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 Heating not Working on my RTH8500WF WiFi Series WiFi Touchscreen

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 heatpump systems). Your thermostat operates between 20-30VAC, any reading outside this range should be addressed by a Professional Contractor.

Why is my Cooling not Working on my RTH8500WF WiFi Series WiFi Touchscreen

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.
