Introduction VFC400-WiFi User Guide 5
IntroductionThe Control Solutions VFC400-WiFi temperature data logger automatically uploads real-time temperature
data1 to your Control Solutions Online cloud account via your existing wireless network. It features a large,
easy-to-read display, along with many familiar attributes known from the Control Solutions family of data
loggers. These include non-volatile memory for up to 16129 temperature readings and a statistical memory,
storing maximum and minimum reading as well as alarm duration for each of the last 30 days.
During recording the display shows…
… the current temperature (of the most recent reading)
… the alarm status, current time and battery status
… an alarm trigger summary of up to the last 30 days (today and 29 days previous)
… the wireless and cloud connection states
At set intervals the VFC400-WiFi uploads these data to your Control Solutions Online cloud account, where they
can be viewed, analyzed and shared with others, or downloaded for further analysis.
Logged temperature data can also be viewed on any PC by plugging the unit into a computer’s USB port via a
micro-USB cable, for example if a Wireless Network is unavailable. View a PDF file, which can be accessed
using PDF software such as Acrobat Reader, or download the data to the free companion software Control
Solutions VTMC, where you can display data in chart, list or summary formats.
FeaturesThe VFC400-WiFi temperature logger features a large display, wireless and USB connectivity with a familiar
LogTag feel.

CommunicationThe VFC400-WiFi offers two means of downloading data
1. Via the built-in Micro USB socket and connection to a PC
2. Via WiFi connection to Control Solutions Online
The unit is configured via a PC using Control Solutions VTMC.
Power SupplyThe same USB socket that is used for communication is also used for providing power to the VFC400-WiFi,
using an external 5V USB power supply. The AAA backup batteries maintain all functionality when USB power
is not connected. A long-life CR2032 lithium backup battery maintains essential functions if the AAA batteries
are empty and external power is not supplied.
PDFThe VFC400-WiFi will generate a detailed PDFreport when plugged into a USB port of a PC. The PDF report
shows a summary of the trip, presents the data in chart and list format and also includes a day summary page,
showing an overview of the statistics collected. A CSV file of the data list is also available.
