1.How to pair the thermostat with Remote Zone Sensors?
1. Click the '+' button at the top right of the interface in 'Menu' -> 'Sensors'
on the thermostat and tap 'Next'.
2. Remove the sensor's back cover and insert the batteries to check if the
sensor indicator light is ashing green continuously.
3. If not, press and hold the button on the back of the sensor for 5 seconds
to reset.
Now you can set the participation period of the sensor. During this period,
the thermostat will take the average temperature of all the sensors that
recently detected motion as the indoor temperature on the main screen.

Tip: During sleep time, the sensor enabled during this period doesn't
care about occupancy, it will always participate in the calculation of the

"Alexa/OK Google, what's the temperature of [thermostat name]"
"Alexa/OK Google, what's the [thermostat name] temperature?"
"Alexa/OK Google, ask [thermostat name] the temperature"
2. Change the temperature in Heat/Cool/Auto mode.

"Alexa/OK Google, make it warmer in [thermostat name]"
Note: If you change the temperature by voice on auto mode. It will
maintain 3 degrees dierence and keep the new temperature as the mid-
point.
For example:
- Thermostat is currently set to 17 degrees for heating and 30 degrees for
cooling.
- You ask Alexa/Google to set the thermostat to 26 degrees.
- It will turn to 24.5 degrees for heating and 27.5 degrees for cooling, using
the 26 degrees as the mid point and maintaining 3 degrees difference
between the heating and cooling target temperature.
3. Change System Mode
"Alexa/OK Google, set [thermostat name] to Heat/Cool/Auto mode"
"Alexa/OK Google, switch [thermostat name] to Heat/Cool/Auto mode"
"Alexa/OK Google, switch to Heat/Cool/Auto mode in the [thermostat
