Removing your old thermostat

1. Turn the power OFF.
   To protect yourself and your equipment, Turn off the power at the breaker box or switch that controls your heating/cooling system.
2. Check that your system is off. Change the temperature on your old thermostat. If you don’t hear the system turn on within 5 minutes, the power is off.
   Note: If you have a digital thermostat that has a blank display, Skip this step
3. Remove the old thermostat’s faceplate. On most thermostats, you can take off the faceplate by grasping and gently pulling. Some thermostats may have screws, buttons, or clasps.
   Do not remove any wires from your thermostat at this time!
4. Make sure there are no 120/240V wires. Do you have thick black wires with wire nuts? Is your thermostat 120V or higher? If you answered yes to either of these questions, you have a line voltage system and the thermostat will not work. If you are unsure visit: honeywellhome.com/support
5. Take a picture of how your wiring looks right now. Be sure to include the letters next to the terminals where the wires are inserted. This will be a helpful reference when wiring your
   thermostat.
   Tip: If the color of your wires has faded or if 2 terminals have the same wire color, use the wire labels provided in the package to label each wire.
6. Record if you have wires in the following terminals. Do not include jumpers as a part of your count. The thermostat does not need jumpers
7. Write down the color of the wires. Check mark the wires that are connected to terminals. Next to the check mark, write down the color of the wire. Do not include jumpers as a part of your count. Check all that apply (Not all will apply):
8. The RCHT8600 thermostat does not support U terminals. If there are wires in terminals that are not listed, you will need additional wiring support. Visit honeywellhome.com/support to find out if the thermostat will work for you.
   Disconnect the wires and remove the old wall plate.
   Use a screwdriver to release wires from terminals. Then, use a wire label to identify each wire as it’s disconnected. The letter on the wire label should match the letter on the terminal.
   Tip: To prevent wires from falling back into the wall, wrap the wires around a pencil.Installing your RCHT8600 thermostat
9. Bundle and insert wires through the UWP. Pull open the UWP and insert the bundle of wires through the back of the UWP. Make sure at least 1/4-inch of each wire is exposed for easy insertion into the wire terminals.
10. Insert the wall anchors. It is recommended that you use the wall anchors included in the box to mount your thermostat. You can use the UWP to mark where you want to place the wall anchors.
    • Level the wall plate.
    • Mark the location of the wall anchors using a pencil.
    • Drill the holes.
    • Insert wall anchors.
    • Make sure anchors are flush with the wall.
      Tip: If your box contains red anchors, drill 7/32” holes. If your box contains yellow anchors, drill 3/16” holes.
11. Set the R-switch position and insert the R-wire or wires. Set the R-switch up or down based on your wiring notes in Step 7. Insert wires into the inner holes of the terminals on the UWP. The tabs will stay down once the wire is inserted.

Power options

 

NOTES:

• The RCHT8600 series Z-Wave thermostat works in battery mode or normal power mode based on its power source. The Z-Wave power mode can only be changed when the thermostat is NOT included in a Z-Wave network. You can check the power mode in the thermostat menu under MENU/DEVICE INFO.
• If a C wire is not used or present, the thermostat must be powered by batteries. The thermostat will operate in LSS mode (power-save, sleep mode) to help conserve battery life after it has been included in a Z-Wave network. The Z-Wave radio supports beaming. It allows other devices in the network to wake up the Z-Wave thermostat, accept commands and then go back to sleep.
• If you need the thermostat to operate in AOS mode (always listening mode) to act as a signal repeater and to increase network reliability, you need to power the thermostat by 24 VAC. The AOS mode information is provided via Node Information Frame (NIF).

Wiring UWP
Push down on the tabs to put the wires into the inner holes of their corresponding terminals on the UWP (one wire per terminal) until they are firmly in place. Gently tug on the wires to verify they are secure. If you need to release the wires again, push down the terminal tabs on the sides of the UWP.

Turn your power ON. Turn on the power at the breaker box or switch that controls the heating/ cooling system.

Thermostat features
The RCHT8600 series Z-Wave Programmable Thermostat is a Z-Wave Plus certified thermostat designed to work with any Z-Wave compliant controller or gateway for easy programming and automation to deliver energy savings and comfort at the same time. The thermostat can be operated in any Z-Wave network together with other Z-Wave certified devices from other manufacturers. All nonbattery operated Z-Wave devices (nodes) within the network will act as repeaters regardless of manufacturer to increase reliability of the network. When integrated
with the app that controls your Z-Wave controller, it lets you program and control your home’s HVAC system as well as control other Z-Wave devices connected to the same Z-Wave controller. Flexible scheduling: The thermostat is fully programmable when not included into a Z-Wave network.

Each day can be programmed for different heating and cooling settings in 4 unique periods (Wake, Away, Home, Sleep). The thermostat scheduling options available differ depending on whether the thermostat is included or excluded from Z-Wave network, on capability of your Z-Wave controller and app to program thermostat. Displays ambient air temperature, % relative indoor humidity and reports HVAC system status: You can display actual temperature or % relative humidity, or to see whether your cooling / heating system is running. Auto change from heat to cool: When Auto mode is selected, the RCHT8600 series Z-Wave thermostat can automatically determine whether your home needs heating or cooling to reach the desired temperature at the right time. Smart Alerts: The RCHT8600 series Z-Wave thermostat can alert you when your HVAC system is not working properly and can remind you for things like when to change your furnace filter. Smart Response Technology: The RCHT8600 series Z-Wave thermostat learns your heating and cooling cycle times to make sure the system delivers the
temperature you want, when you want it. (Available only if the local thermostat schedule is enabled.) Power method: Designed for battery operation (3 x AA batteries) or for 24 VAC power operation (via a “C” or common wire).

Z-Wave configuration parameters

If your gateway/hub/controller supports configuration function, you may remotely configure or change the default thermostat configuration parameters. For detailed table with all available Z-Wave configuration parameters search for RCHT8600 series Z-Wave Thermostat in the Z-Wave certified products section on http://Z-Wavealliance.org

Z-Wave setup

To add to include or remove to exclude the thermostat from Z-Wave network, go to thermostat MENU/Z-WAVE SETUP.

• Touch Select. You will be asked to set your primary controller to INCLUDE MODE. Please refer to the user manual of your Z-Wave controller.
• After inclusion procedure has been initiated on your Z-Wave controller, touch Select on the thermostat.
• If the inclusion procedure is successful, “INCLUDED”, the node ID, and the Z-Wave connected status icon appear on the screen. If the procedure fails, “FAILED TO INCLUDE”
  appears on the screen. If this happens, position the thermostat closer to the Z-Wave controller and repeat the inclusion rocedure.
• Your controller will indicate whether the thermostat was successfully added to its network. (Please refer to the user manual of your Z-Wave controller.)
  NOTES:
• Once the thermostat is included into the Z-Wave network, it assumes to be programmed from your Z-Wave controller and the program schedule on the thermostat is turned OFF by default. If the thermostat is not included into the Z-Wave network, then this thermostat will function as normal programmable thermostat. For more information, see “Scheduling options” on page 17.
• Before adding the thermostat to a Z-Wave network, check that it does not already belong to one. If the thermostat is included in Z-Wave network, it offers to exclude. If the thermostat is excluded from Z-Wave network, it offers to include. You can also check the status by viewing the Node ID located in the thermostat MENU/DEVICE INFO. An excluded thermostat should show zero for the Node ID (000).
• hether you are adding the thermostat for inclusion or removing for exclusion from Z-Wave network, first you have to initiate it on your Z-Wave controller. Please refer to the user manual of your Z-Wave controller.
• For other specific tasks, such as adding the thermostat to home automation scenes or groups, refer to the Z-Wave controller instructions.
• The RCHT8600 series Z-Wave thermostat works in the optional Z-Wave battery mode or normal power mode based on its power source. The Z-Wave power mode can only be changed when thermostat is NOT included in Z-Wave network. You can check the power mode in the thermostat menu under MENU/DEVICE INFO.
• If 24 VAC power source is not used or available, the thermostat must be powered by batteries. The thermostat will operate in LSS mode (power-save, sleep mode) to help conserve battery life after it has been included in a Z-Wave network. The Z-Wave radio supports beaming. It allows other devices in the network to wake up the Z-Wave thermostat, accept commands, and then go back to sleep.
• If you need the thermostat to operate AOS mode (always listening mode) to act as signal repeater and to increase network reliability, you need to ask your professional installer to power the thermostat by 24 VAC.

Z-Wave connection status

Z-Wave connection status is located in the upper-right Corner of the screen.

• Thermostat is included and connected to a Z-Wave network.
• Thermostat is excluded from a Z-Wave network.
• Thermostat is either included in a Z-Wave network but the Z-Wave signal is lost, or is included but AC power is lost (battery used as backup). In this case, Z-Wave radio is turned off to preserve battery life. AC power must be restored or you have to change the power mode. It can be done via excluding thermostat from Z-Wave network and including again in battery power mode where batteries are used as main power source. You can check the actual power mode in the thermostat MENU/DEVICE INFO.

Program schedule overrides

If the thermostat is included in Z-Wave network it typically follows the setting on your Z-Wave controller. If you adjust the temperature setting, it overrides the current setting until new state (eg. Home/Away) and/or the new temperature setting is received from Z-Wave controller. Setting of Hold until time and Permanent hold (see below) will not be available on the thermostat screen at this time. There are several scheduling options available for the thermostat. For more information, see “Scheduling options” on page 17. If the thermostat is not included in Z-Wave network and the thermostat is following local time based schedule only, you can set what time the new temperature setting will be held until or you can hold the new temperature setting permanently.

Program schedule override (temporary)

1. Touch or on the thermostat home screen to set your desired temperature. Hold Until will appear together with the time the hold will end.
2. To change when the hold will end, touch Hold Until and wait until the time starts blinking. Then, touch or to set when you want the hold to end. Touch Hold Until once more to confirm changes and return to the home screen. After the hold period ends, the thermostat will automatically return to the program schedule. If you want to cancel the hold, touch Hold Until and then touch Run Schedule.

Program schedule override (permanent)

1. Touch or on the thermostat home screen to reach your desired temperature. Hold Until will appear together with the time you want the hold to end.
2. Touch Hold Until. Permanent Hold will appear on screen. Touch Permanent Hold to hold this temperature until you manually change it. To end permanent hold and return to the
   program schedule, touch Permanent Hold and then touch Run Schedule.

Wiring—conventional systems
Alternate wiring (conventional systems) If labels do not match terminals, connect wires as shown below (see notes, below).
NOTES:

1. If you must connect both R and Rc wires, set the R Slider Tab to the down position (2 wires).
2. If your old thermostat had both R and RH wires, set the R Slider Tab to the down position (2 wires). Then connect the R wire to the Rc terminal, and the RH wire to the R terminal.
3. If your old thermostat had only 1 C or C1 wire, connect it to the C terminal. If your old thermostat had 2 C or C1 wires, wrap each separately with electrical tape and do not connect them.

Connect wires: heat pump

1. Match each labeled wire with same letter on new thermostat.
2. Insert the wires into the matching terminal.
   NOTE: If you have difficulty inserting wires, you may have to press down the terminal push button next to the corresponding terminal. Labels don’t match? If labels do not match the letters on the thermostat, see “Alternate wiring (for heat pumps only)” below.

Alternate wiring (for heat pumps only)
NOTES:

1. Keep R Slider Tab in the up position (1 wire).
2. If your old thermostat had both V and VR wires, stop now and contact a qualified contractor for help.
3. If your old thermostat had separate O and B wires, attach the B wire to the C terminal. If another wire is attached to the C terminal, stop now and contact a qualified contractor for help.
4. If your old thermostat had Y1, W1 and W2 wires, stop now and contact a qualified contractor for help.

NOTE: Do NOT use W for heat pump applications. Auxiliary heat must wire to AUX or E.

Smart Response® Technology
This feature allows the thermostat to “learn” how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the time you set. For example: Set the Wake time to 6 am, and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6. The message “Recovery” is displayed when the system is activated before a scheduled time period.

Battery replacement

Batteries are required to provide power when common wire is not used. Batteries are recommended to provide backup power if common wire is used. Install fresh batteries immediately when the low battery icon appears. The icon appears about two months before the batteries are depleted. Even if the low battery icon does not appear, you should replace batteries once a
year, or before leaving home for more than a month. If batteries are inserted within two minutes, the time and day will not have to be reset. All other settings are permanently stored in memory, and do not require battery power.
NOTE: When replacing batteries, alkaline batteries are recommended.

Enabling/disabling Smart Response

Over time, your RCHT8600 series Z-Wave thermostat will learn how long it takes your system to reach the desired temperature. It can then turn on your heating or cooling equipment
