PRODUCT DESCRIPTION
Sensors Wx7xx with WiFi interface
are designed to measure temperature, relative humidity, barometric pressure, CO
2
concentration
of the air in the non-aggressive environment. Communication with the sensor is done via wireless WiFi network. Sensor is designed to send
measured values to online portal COMET Cloud. It can provide values via www pages and by the Modbus TCP protocol as well. Sensors
continuously evaluate measured values, in case of limits are exceeded, alarm e-mail is sent and set acoustic or optical signalisation.
Measured values and alarm states are shown at the LCD display.

INSTALLATION AND CONNECTION
Fasten
the sensor directly to the wall using two screws or insert it into the lockable holder LP100 (optional accessories). The sensor
is designed for a fixed installation. Keep the probes and device away from sources of electromagnetic interferences.
•
always install the devices vertically with the antenna upwards in places with sufficient quality of the WiFi signal (check e.g. via
a WiFi-enabled cell phone). Please make sure that the environmental characteristics correspond to the operating conditions
•
connect the probes. The maximum cable length of the Digi/E probe is 15 m. Recommended cable length of the Pt1000/C probes
is up to 15 m (max. 30 m)
•
connect supplied power source into plug socket (use supplied cable to connect device into USB-C connector)
DEVICE SETUP

•
at the menu
Channels
it is possible to set alarm limits
•
to be all changes applied it is mandatory to
save settings
. After setup of SSID and saving settings is symbol
CL
shown.
BUTTONS CONTROL
•
switching between client (CL) / access point mode (AP):
-
press button MODE for longer than 3 seconds and after that confirm by button SET
•
showing current IP address of the WiFi sensor:
-
short press of the MODE button
The sensors do not require any special operation and maintenance.
We recommend doing regular verification of the accuracy
of calibration measurements.
