• Before installing or servicing the thermostat,

turn o power to the system at the circuit

breaker.

• Leave power o until you have nished

installing or servicing.

• Shorting the electric terminals at the control

on the heating or cooling system may damage

the thermostat. Do not test the system this way.

• You must follow all local codes and ordinances

for wiring the system.

• This thermostat should only be powered by 4

AA alkaline batteries or a listed class 2 power

supply at 24 VAC (C-Wire or wall transformer).

• An amperage higher than 1 amp to each

thermostat relay load may cause damage to

the thermostat.

• 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.

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 wall, approximately

5 ft. (1.5m) above the oor

in a frequently used room.

• Do not install in locations

near appliances or devices that

aect 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

aect 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 reect the rate

of temperature change in the

room. Avoid areas behind open

doors, corners, and alcoves.

• Wait until construction

and painting are nished

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 O

• Turn all heating and cooling systems o.

This can be done at the circuit breaker.

CAUTION: DO NOT REMOVE the existing

thermostat until power has been turned o

at the circuit breaker.

Once power to the heating AND cooling systems is

o, 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 unidentied wire, it may be necessary to

identify the wire where it connects to the heating

or air conditioning equipment.

8 | Alarm.com Smart Thermostat Product Manual

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 back plate as a guide.

Mark where the screws will go

with a pencil through the screw

holes on the back plate.

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

back plate to the wall.

TIP: Drill holes with 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 conguring

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 back plate

terminal board with needlenose

pliers.

Insert Batteries Into the Thermostat

The thermostat can be powered by 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

specied 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“BAT”

ashing on the display. If the batteries drain, the

thermostat could leave the HVAC system on,

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.
