There is no need to perform Steps 1 thru 5 if you are installing a Communicating HV AC system
with communicating thermostats in all zones...The UT3000 programs steps 1 thru 5 for you!
If you are installing non-communicating thermostats in some or all zones, you must perform steps 3 and 4
and specify the type of non-communicating thermostats being used and the reversing valve logic O or B.
Use the Forward & Back buttons to
navigate thru the Menu Features. Use
the Up & Down buttons to change or
adjust the options available in that
feature. Place a check mark next to
each selection in the box for future
