FCC Compliance Statement
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules.These limits are designed
to provide reasonable protection against harmful interference in a residential
installation.This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that
of the receiver.
• Consult the dealer or an experienced radio or TV technician for help.
Notice: Only peripherals complying with FCC limits may be attached to this
equipment. Operation with noncompliant peripherals or peripherals not
recommended by Venstar, is likely to result in interference to radio and TV
reception. Changes or modifications to the product, not expressly approved by
Venstar could void the user’s authority to operate the equipment.
FCC - INDOOR Mobile Radio Information:
To comply with FCC/IC RF exposure limits for general population / uncontrolled
exposure, the antenna(s) used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons and must not be co-located
or operating in conjunction with any other antenna or transmitter.
This Device complies with Industry Canada License-exempt RSS standard(s).
Operation is subject to the following two conditions: 1) this device may not
cause interference, and 2) this device must accept any interference, including
interference that may cause undesired operation of the device.

This Mini thermostat has the ability to receive updates to its firmware.
Periodically firmware updates are released by the manufacturer to add features
and/or performance enhancements.This manual was produced reflecting the
most current firmware/feature set at the time of publication, firmware rev. 1.0.
Firmware releases after rev. 1.0 may not be adequately depicted in this manual.
Please refer to the appropriate website or contact your place of purchase to learn
about changes to the thermostat after firmware release 1.0.
Under Industry Canada regulations, this radio transmitter may only operate using
an antenna of a type and maximum (or lesser) gain approved for the transmitter
by Industry Canada.To reduce potential radio interference to other users, the
antenna type and its gain should be so chosen that the equivalent isotropically
radiated power (e.i.r.p.) is not more than that necessary for successful
communication.
Cet appareil est conforme avec Industrie Canada, exempts de licence standard
RSS(s). Son fonctionnement est soumis aux deux conditions suivantes: 1) ce
dispositif ne doit pas causer d’interférences, et 2) ce dispositif doit accepter
toute interférence, y compris les interférences qui peuvent causer un mauvais
fonctionnement de l’appareil.
En vertu des règlements d’Industrie Canada, cet émetteur de radio ne peut
fonctionner en utilisant une antenne d’un type et maximale (ou moins) Gain
approuvé pour l’émetteur par Industrie Canada. Pour réduire les interférences
radio potentielles aux autres utilisateurs, le type d’antenne et son gain doivent
être choisis afin que la puissance isotrope rayonnée équivalente (PIRE) ne est pas
plus de ce qui est nécessaire pour une communication réussie.
We, Venstar, declare under our sole responsibility that the device to which
this declaration relates: Complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.

Auto-Changeover: A mode in which the thermostat will turn on the
heating or cooling based on room temperature demand.
Cool Setpoint: The warmest temperature that the space should rise
to before cooling is turned on (without regard to deadband).
Deadband: The number of degrees the thermostat will wait, once a
setpoint has been reached, before energizing heating or cooling.
Differential: The forced temperature difference between the heat
setpoint and the cool setpoint.
Heat Setpoint:The coolest temperature that the space should drop
to before heating is turned on (without regard to deadband).
Icon: The word or symbol that appears on the thermostat display.
Mode: The current operating condition of the thermostat (i.e. Off,
Heat, Cool, Auto, Program On).
Non-Programmable Thermostat: A thermostat that does not have the
capability of runningTime Period Programming.
Programmable Thermostat: A thermostat that has the capability of
runningTime Period Programming.
Pre-Occupancy Purge: Fan operation prior to Occupied 1.
Temperature Swing: Same as Deadband.
Time Period Programming: A program that allows the thermostat
to automatically adjust the heat setpoint and/or the cool setpoint
based on the time of the day.

Glossary of Terms
Installation Instructions
1
Remove and Replace the old thermostat
To install the thermostat properly, please follow these step by step
instructions. If you are unsure about any of these steps, call a qualified
technician for assistance.
• Installation tools: Small flat blade screwdriver, Phillips screwdriver,
wire cutters and wire strippers.
• Make sure your Heater/Air Conditioner is working properly before
beginning installation of the thermostat.
• Carefully unpack the thermostat. Save the screws, any brackets,
and instructions.
• Turn off the power to the Heating/Air Conditioning system at the main
fuse panel. Most residential systems have a separate breaker or
switch for disconnecting power to the furnace.
• Remove the cover of the old thermostat. If it does not come off easily,
check for screws.
• Loosen the screws holding the thermostat base or subbase to the
wall and lift away.
• If you have a smart phone handy, take a photo of the wiring for
future reference.
• Disconnect the wires from the old thermostat. Tape the ends of the
wires as you disconnect them, and mark them with the letter of the
terminal for easy reconnection to the new thermostat.
• Keep the old thermostat for reference purposes, until your new
thermostat is functioning properly.
