Venstar ACC-TSENWIFI User manual

model: ACC-TSENWIFI
Temperature Sensor with Wi-Fi
Installation Instructions
Before you begin the installation:
The Venstar Congurator App is needed to congure this sensor.
This App may be downloaded from your mobile device store.
Select a suitable location for the ACC-TSENWIFI sensor. Please note
that the sensor must have good Wi-Fi reception from the access point
it is intended to join. Do not mount in direct sun or direct rain.
Please have handy the Owner’s Manual for the thermostat that will
be paired with the sensor. Venstar thermostats have unique pairing
procedures.
OVERVIEW
This wireless temperature sensor may be used as a room remote temperature sensor, an outdoor temperature sensor, a return air
temperature sensor or a supply air temperature sensor.
The ACC-TSENWIFI is equipped with an onboard temperature sensor. An external sensor, such as the duct sensor included in the
ACC-TSENWIFI box, may be connected to the rear terminals of the ACC-TSENWIFI as an option. For accurate temperature sensing
the 10k thermistor must adhere to the table on page 3.
Venstar thermostats vary by model in the way they can use remote sensors. This includes averaging, control to, or monitoring features.
Please consult the Owner’s Manual of the thermostat that you are going to pair this sensor with to understand its capabilities and
pairing procedure.
This sensor is compatible with all Venstar Wi-Fi thermostats that contain the latest rmware. Please consult Venstar.com for a complete
listing of compatible thermostats.
Note:This sensor must be connected to the same local network as the thermostat(s) that will use the sensor data.

Rear Panel Connections
When the ACC-TSENWIFI type is congured to be a supply
or return air temperature sensor, the sample rate is once
every 20 seconds. External power (24Vac) is required to
support this sampling rate.
If 24Vac is not supplied to the rear terminals of the sensor
and 4 AA batteries are installed, the sampling rate of the
sensor will default to once a minute.

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 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 modications 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.
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 an 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.
