LS-90 Operation Guide
The LS-90 programmable communicating
thermostat operates via a high-quality, easy-
to-use touch screen. To program or adjust
your LS-90, simply touch your finger or the
stylus firmly to the screen. The screen will
automatically light up and you will hear a
“beep.” The screen will respond differently to
different types of touches, so you may want
to experiment with both your finger and with
the stylus, which is included with the LS-90,
to see what works best for you.
