Today’s programmable and communicating thermostats often need a “common wire” to
power the radio modules and other electronics. On average, 30% of all homes do not
have a common wire at the thermostat. The iO-W1-100 uses multiplexing technology to
allow an additional signal to be passed through the common wire.
