Getting Started

Tools Needed

Small Phillips screwdriver

Level

To avoid electrical shock and to prevent damage to the furnace and thermostat, disconnect

the power supply before installing or servicing the thermostat or any part of the HVAC

system. This can be done at the circuit breaker labeled either furnace or air handler.

• Do not turn power back on until work is complete.

• Do not short (jumper) across electric terminals at the control on the furnace or air

conditioner to test the system. This can damage the thermostat.

• Your thermostat is a precise instrument. Handle it with care.

• All wiring must conform to local codes and ordinances.

• This thermostat is designed for use with 4AA alkaline batteries and/or 24-volt AC C

wire (or a 12- 24 AC or DC source) or millivolt gas systems. Each thermostat relay load

should be limited to 1.0 amp; higher amperage can cause damage to the thermostat.

Installation Location

To avoid having to move your wiring to a new location, mount the

thermostat in place of the old thermostat.

• Install the thermostat on an inside wall of an often-used room, about 5 ft. (1.5m) above

the oor.

• Do not install where there are unusual heating conditions, such as: in direct sunlight;near

a lamp, radio, television, radiator register, replace; near hot water pipes in the wall; or

near a stove on the other side of a wall.

• Do not locate in unusual cooling conditions, such as: on a wall separating an unheated

room; or in a draft from a stairwell, door, or window .

• Do not locate in a damp area. This can lead to corrosion that will shorten the

thermo- stat’s life .

• Do not locate where air circulation is poor, such as: a corner, an alcove, or behind an

open door.

• Ensure that the thermostat is level on the wall.

Vivint Element Installation Guide

Wiring

• Always use new Alkaline batteries.

• Do not use rechargeable batteries of any type. They will not operate the

thermostat properly and may lead to damage.

• Do not mix old and new batteries.

• Do not mix battery types, for example Lithium with Alkaline.

• Do not dispose of batteries in re. Batteries may explode or leak.

• If you are leaving your home for a month or more, you should replace the

batteries as a precaution against battery failure in your absence.

• Always replace the batteries as soon as the “Low Batt” warning ashes.

The thermostat is a battery-powered device; you should replace the batteries

before they run out.

• Always replace the batteries once a year, even if the “Low Batt” indicator

does not ash. Replacing the batteries also helps to prevent leakage that can

corrode and damage the thermostat.

• Failing to replace the batteries when necessary could cause the thermo-

stat to lose power or malfunction. If the thermostat loses power, then the

thermostat will not control the temperature, which could result in your HVAC

system not functioning as you intended and lead to possible damage from

excessive heating or cooling.

- If the thermostat batteries fail with the heat OFF, this can result in NO

HEAT and possible frozen or broken pipes and water damage.

- If the thermostat batteries fail with the cool OFF, this can result in NO

COOL and could cause possible damage or excessive temperatures.
