Frequently Asked Questions:
What if I go on vacation?
One option is to change your program. However, it might be easier to override the program by pressing the Next Zone button until
the desired zone is displayed (Zone 1 is recommended for convenience). Press the Set Time/Temp buttons until the heat icon flashes,
then press the up or down arrows to change the desired heating temperature. Repeat this step for the cooling temperature. Press the
Hold button to lock in these settings for that zone. Press the All Zone button to hold these same settings for all the remaining zones.
When you return from vacation press the All Zone button then the Hold button to return to the programmed settings.
What if I have guests, and I need to temporarily change the temperature?
Press the Next Zone button until the desired zone is displayed. Press the Set Time/Temp button until the heat or cool icon is flashing.
Press the up and down buttons until the desired temperatures are displayed. These settings will stay in effect until the next period.
If you need to override the temperatures for more than one period, press the Hold button. Press the Hold button again to return the
system to programmed settings.
What if I have a guest room or a zone that is programmed to OUT, and now it is occupied?
You can temporarily bypass the program as follows: Press the next zone until the desired zone is displayed. Press the Out button to
change the status to occupied. Press the up and down buttons until the desired temperatures are displayed. These settings will stay
in effect until the next period. If you need to override the settings for more than 1 period, press the Hold button. Press the Hold button
again to return the system to the programmed settings.
What if I know that I will not be home during a period that I scheduled as occupied?
Press the Next Zone button until the desired zone is displayed. Press the Out button to change that period to unoccupied. Press the
Hold button if you need to maintain the OUT feature for more than 1 period. Press the Hold button again to return the system to
programmed settings. Change other zones if necessary.
What if I have indoor pets, should I program a period to OUT?
You will need to decide what is best for your particular situation. The OUT function is used when zones are unoccupied. Those
zones will not normally be conditioned unless the temperature in that zone drops below 60° or rises above 85°. Even if a zone is
coded to OUT, it is unlikely that the zone will reach either of these extremes.
How can I save money on my energy bills?
In order to improve energy savings, program your unoccupied zone periods to OUT so those zones will not be conditioned when
you are not there or are not using them. Also, set back the temperature at night to limit conditioning while you are asleep.
Why is conditioned air entering a zone that I programmed as OUT? Doesn’t this waste energy?
Your Zone Perfect Plus system has been designed to protect your heating and cooling equipment. Occasionally if 1 small zone is
requesting less conditioned air than the equipment is producing, it may “dump” this excess air into an unoccupied zone. This is not
unusual and serves as a protection device for your equipment. Since the system is satisfying the minimum demand requirements, no
extra energy is wasted.
What if my power goes out, will I lose my program?
No. However, it is recommended that you record your program schedule on the comfort chart, and keep it along with this guide in
a convenient place.
What if my display shows an E, a number, or a ”--” instead of the temperature?
An error has occurred in your system. Note the error number, and promptly contact your dealer with this information.
Why does my system turn on before a scheduled temperature change?
Your dealer has enabled the smart recovery feature. It provides a gradual temperature transition from one period to the next for added
comfort and savings.
