Mode of operation.
•
Open lid warning.
•
Network Signal indicator.
There are five switches provided on the device, which allows for the following functionality:
•
Switching the device ON/OFF
•
Setting the temperature of the chamber.
•
Soft resetting the device.
The device can be controlled through the five switches provided on the panel. The power switch and set
button operate via long press (3 to 5-second-long continuous press), and the other switches work via
normal press action.
The display enters power saving mode during operation and can be switched on by pressing any button
on the panel.

Control System
The chamber temperature is maintained through a Proportional Integral Derivative (PID algorithm) on-
chip, which allows for fine control of temperature in the range of 0.5°C. There are two temperature sensors
used on the device with a detection range of 0.5°C. This redundancy feature ensures smooth functioning
of the device and temperature accountability even during instances of a single sensor failure.
The control boards also incorporate a GPS tracker and a data logging system which enables remote
monitoring of device parameters through a dashboard.

Battery
The battery on-board Emvólio is a Lithium-Ion battery rated at 200Wh. It can sustain the device operation
continuously for 8
–
12 hours, beyond which the device has to be plugged in for charging, or the battery
pack must be replaced. The battery is charged via a standard 110V to 12V DC battery charger. The
charger can also power the device operation for continuous usage.
#
The battery has a shelf life of 3 years, or 600 cycles.*
NOTE!
*Under ideal use conditions. Based on ambient conditions and usage patterns, battery performance can vary.
#
The device is meant to be used for transporting contents requiring refrigeration in a safe and controlled manner.
This device is not intended to replace WHO mandated ice-lined refrigerators. Doing so may lead to significant
depreciation in the life of the device.
