Using the ExP – Expansion Port – to program the thermostat
Your Perferred™ thermostat has an unique ExP –
Expansion Port – that allows you to use a digital memory
card to program the thermostat on your computer. The
ExP is sold as an accessory.
Remove the dual port digital memory card and insert it in
your computer’s digital or USB memory card reader. Follow the onscreen
instructions to program temperatures, the corresponding time, and the
day of the week. You can even schedule your thermostat to remind you
to change your furnace filter, the UV light or humidifier pad. When you’ve
completed the process on your computer, simply reinsert the card back
into the EXP port on the thermostat. It will automatically transfer the
settings on the card to the thermostat.
