LOCATION
If replacing an old thermostat, the new thermostat can be mounted in its place. If a new location is desired it will be necessary to move the wiring.
New installations and relocation should follow the accompanying guidelines to ensure the most accurate temperature reading and ease of use.

• Mount thermostat on an inside the wall, approximately 5 ft. (1.5m) above the floor in a frequently used room.
• Do not install in locations near appliances or devices that affect the local temperature such as televisions, lamps, or dryers.
• Avoid areas that are exposed to large temperature variances, such as direct sunlight, near an AC unit, above or below auxiliary heat and air vents, and drafts from windows.
• Be aware of what is on the other side of the wall where the thermostat is being installed. Do not install on walls adjacent to unheated rooms, stoves, or housing hot water pipes.
• Damp areas will not only affect the humidity reading of the thermostat but could lead to corrosion and shorten the life of the thermostat.
• Install in a location with good air circulation. Stagnant air will not accurately reflect the rate of temperature change in the room. Avoid areas behind
  open doors, corners, and alcoves.
• Wait until construction and painting are finished before installing.

PREPARATION

The Existing Thermostat

1. Test the System
   Verify that the heating and/or cooling system is operating properly before you try to install the new thermostat.
   DO NOT test the system by shorting electric terminals at the furnace or air conditioner. This may damage the thermostat.
   
2. Turn Power Off
   • Turn all heating and cooling systems off. This can be done at the circuit breaker.
   
   
   CAUTION: DO NOT REMOVE the existing thermostat until power has been turned off at the circuit breaker.
   Once the power to the heating AND cooling systems is off, follow these steps:
3. Remove Thermostat Cover
   • Remove the cover from the existing thermostat.
   Do not disconnect the wires yet.
   TIP: Take a picture of the wires before you detach them from the existing thermostat for future reference.
4.  Label All Existing Wires

• Label all existing wires, one at a time, with the labels provided.
Make sure the wires are labeled correctly. If you have an unidentified wire, it may be necessary to identify the wire where it connects to the heating or air conditioning equipment.

TIP: Take another picture of the wires to document connections for easy reference. Do not disconnect wires before labeling them.

CAUTION: Wiring can vary for each manufacturer. Label all wiring before removing it from the existing thermostat.

• Disconnect all of the wires and remove the existing thermostat.
  TIP: Remember to secure the wires so they don’t fall into the wall.

Prepare the Wires
Follow these guidelines for safe and secure wire connections:

• Ensure the wires are a proper gauge between 18-24 AWG.
• Make sure wires have exposed straight ends about 1/8” long.

CAUTION: Verify that the system is 24 VAC. If the old system is labeled as 120 or 240 volts or has wire nuts, the system is high voltage. Do not install the thermostat to a high voltage system. Contact a local HVAC professional for help.

INSTALL YOUR NEW THERMOSTAT

Install the Back Plate
Use the bubble level provided on the backplate as a guide. Mark where the screws will go with a pencil through the screw holes on the backplate.

TIP: If necessary, use the trim plate to cover up any marks or holes left from the old thermostat. Attach the trim plate before securing the backplate to the wall.
TIP: Drill holes with a 3/16” drill bit to tap in the drywall anchors for added support.

Wire Your New Thermostat
Reconnect the wires to the new thermostat and indicate the connected wires with a pencil in the image below. This information will be needed when configuring the thermostat.

TIP: If you have extra wires do not install them in the new thermostat. Please contact your local HVAC professional for additional assistance.

• If you have R, connect it to RH.
• If you have RH & RC, remove the black jumper in the lower-left corner of the backplate terminal board with needlenose pliers.

• Z can be used for W3, H, DH, or O/B Zoning

Terminal Designations

Insert Batteries Into the Thermostat

The thermostat can be powered by a battery or 24 VAC. If a wall transformer is used to power the thermostat, connect between C and RH.
Ensure the batteries are installed following the specified polarity markings on the thermostat.

CAUTION: Special Battery Warning

•  Always replace the batteries as soon as you have low battery levels, indicated by “LOW” then “BATT” flashing on the display. If the batteries drain, the thermostat could leave the HVAC system on or off, overheating or freezing the home.
• Always replace the batteries at least once a year. This will protect the thermostat from damage and corrosion by leaking batteries.
• If the home is unoccupied for a month or more, such as vacation homes, you should replace the batteries as a preventive measure against battery failure while you are away.
• Always use new batteries as replacements.

Install Thermostat Body to Back Plate

Verify that any excess wire is tucked back into the wall to allow room for the thermostat to sit flush against the backplate.
Press the thermostat body firmly into the backplate mounted to the wall. Ensure that the pins on the body are correctly aligned with the header attached to the terminal board on the backplate. Failure to do so could cause damage to the thermostat.

Turn the Power On
Restore power to all the heating and cooling systems. This can be done at the circuit breaker.

1. Put the thermostat in OFF mode (No mode icons are lit).
2.  Put the Z-Wave controller into inclusion mode. Refer to the controller documentation for more information.
3. Press and hold the DOWN∨ button on the thermostat to begin inclusion mode. Release the button when the RADIO icon lights up.
4. When the RADIO icon becomes solid, the thermostat has been included.
5. Log in to your online account (www.alarm.com/login) to sync the thermostat with the Alarm.com system, or contact an Alarm.com professional for installation setup.

Write your login information below once you have chosen a personal password.

CONFIGURE THE SYSTEM

The thermostat configuration will be done on your online account. Here you can configure the parameters of the system, such as Heat Pump or Normal, number of heat and cool stages, heating fuel, calibration temperature, and configurable terminal (Z). In your online account, you will have to enter the thermostat configuration. Refer to page 7 for the appropriate diagrams when you set up the thermostat.
While the default settings will be sufficient in most cases, you also have the option to change advanced configuration settings, such as SwingDifferential, Recovery Settings, Fan Circulation Period and Duty Cycle, Maximum Set Points, Minimum Set Points, and Thermostat Lock.
The thermostat can be configured locally for the most common configurations. Please see Page 12 for instructions.

WARNING: Use caution when changing advanced configuration settings. These configuration settings should only be changed by those familiar with heating and cooling systems’ parameters. Contact a local HVAC professional for help.

CHECK THE SYSTEM

WARNING: Do not test the AC during cold weather or heat during hot weather. Wait for mild weather to fully test the system.

To Check Heating

• When in EMER mode, the display will read EMER when the thermostat wakes up and the HEAT icon will be displayed. Changing the mode will leave EMER mode.
• In AUTO, the brighter icon will indicate which setpoint is currently displayed and active HEAT or COOL
  
• After 5 seconds the display will return to the current room temperature. The mode icon will become solid to indicate this. If powered by the “C” wire, the thermostat display will remain lit. If the thermostat is running on battery power only, the display will turn off after 5 seconds to conserve energy. The thermostat will continue to operate while the display is off.

TROUBLESHOOTING

Heating or Cooling Doesn’t Turn On When the Set Point is Above or Below the Room Temperature
To prevent damaging the compressor, the thermostat inserts a delay when cycling the compressor. If you think the system should be on and it’s not, then change the setpoint to be 2 degrees beyond the current setpoint and wait 5 minutes to see if the system turns on. If not, contact a local HVAC professional.

Heat Pump is “Cooling When it Should be Heating” or “Heating When it Should be Cooling”
Because both types of heat pump reversing valves share a single terminal on your thermostat backplate, you need to be sure you have the thermostat configured for the correct wire. Try switching the O/B configuration setting through your online account. Contact a local HVAC professional for further help with this issue.

Exclude the Thermostat From the Z-Wave Network

If for some reason the thermostat must be excluded from the network, follow the steps below to do so.

1.  Set the thermostat to OFF mode.
2. Press and hold the exclusion button on the Z-Wave controller. Refer to controller documentation for more information.
3. Press and hold the DOWN∨ button on the thermostat to enter exclusion mode. Release the button when the RADIO icon lights up.
4.  When the RADIOicon flashes red, the thermostat has now been successfully excluded from the network.

Batteries Drain Quickly

If a thermostat is included using a “C” Wire, that information is saved in the network and cannot be changed unless excluded and included again without a “C” wire connected. The same applies to thermostats included on battery power.

If you find your thermostat batteries are draining unusually fast, make sure the “C”-Wire connection is still intact. If a device is included using the “C” Wire, the Z-Wave communication never sleeps, and the thermostat will act as a repeater, sending messages for other devices as well. If the “C” Wire is removed, this kind of activity will drain the battery very quickly.
