Venstar T4700 Operating instructions

with Humidity Control

FCC Compliance Statement

This equipment has been tested and found to comply with the limits for an

intentional radiator, pursuant to Part 15, subpart C 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 in radio communications.

However, there is no guarantee that the 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 orTV 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.

Follow the Installation Instructions before proceeding. Set the

thermostat mode to “OFF” prior to changing settings in setup

or restoring Factory Defaults.

CAUTION

This Voyager 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

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

Glossary of Terms

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.

Dehumidify: To reduce the amount of moisture in the air.

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).

Humidify: To increase the amount of moisture in the air.

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).

Non-Programmable Thermostat: A thermostat that does not have the

capability of running Time Period Programming.

Override: During programmed unoccupied periods, pressing the

Override button will force the thermostat into occupied settings. During

programmed occupied periods, pressing the Override button will force

the thermostat into unoccpied settings.

Programmable Thermostat: A thermostat that has the capability of

running Time Period Programming.

Reheat: Running the cooling and 2nd stage strip heaters at the same

time in order to dehumidify the air without signicantly cooling down

the room temperature.

Temperature Swing: Same as Deadband.
