for a complete list of
alerts applicable to these smart devices that are
generated by the S40 thermostat.
Side Switch
The primary reason for this switch is to turn off
the internal fan in case the device is installed in
a bedroom.
The side switch on the

position turns on the internal fan and transmits air
