Data Source Selection

It is necessary for thermostat to know the environment temperature and humidity to display on the screen and achieve the accurate control. The thermostat provides 4 kinds of data sources for different application environments:
Source Mode Description
Internal The thermostat has already equipped the temperature and humidity sensors.
NTC The thermostat provides a NTC input to connect to a NTC temperature sensor. When connecting a NTC sensor, the thermostat will use NTC sensor as temperature source and internal sensor as humidity data source.
LNS The thermostat is able to receive the temperature and humidity data from LoRaWAN® network server.
D2D The thermostat is able to receive the temperature and humidity data from Milesight sensors via Milesight D2D feature.
How to Select the Data Source
The thermostat internal sensors can suit for most of applications without extra sensor deployment. However, if one of the following scenarios occurs, you may choose to use other data sources:
  • The accuracy of the internal sensors does not match the requirement;
  • There are unavoidable temperature influences at target installation location of the thermostat;
  • The target installation location of the thermostat is not representative.
If you decide not to use internal sensors, please select the data source mode depending on the sensors you have:
  • NTC Sensor: select the NTC mode if your sensor can suit the requirement of thermostat NTC input.
  • Milesght Sensor: If this model supports D2D Data Sending feature and is within the transmission distance with the thermostat, select D2D mode; if not, select LNS mode.
  • Other type sensors: select LNS mode.
How to Configure the Data Source
The thermostat uses internal sensors by default and provides the downlink command to switch data sources. After switching, please refer to the following information:
Calibration
The thermostat supports numerical calibration for temperature and humidity data. The thermostat will use the calibration results to display on the screen and achieve temperature control.
Note: This only works when the data source is internal or NTC sensor.
