PROGRAMMABLE / NON-PROGRAMMABLE SET-
TING — It is possible to convert the thermostat operation
from programmable to non-programmable. This eliminates the
advanced features. When switching to the non-programmable
format, the programming, hold, holiday and Smart Recovery
features are lost. Switching to non-programmable operation
also means that some of the thermostat's energy saving features
are lost. The time of day and day of the week will still show on
the display and the user will still be able to increase or decrease
the temperature settings manually.
To switch thermostat operation, perform the following:
1. Open the thermostat door.
2. Press and hold the buttons underneath the heat and cool
set points simultaneously. The screen will display "01"
and up to three reset reminders.
3. Press the UP arrow button until 01 changes to 05. The P
icon (the default setting) will be displayed next to it.
4. Press the rightmost soft key and then press the UP arrow
button until the desired operation is shown. P stands for
programmable and nP stands for non-programmable.
5. Press the DONE button.
6. Close the thermostat door.

set points simultaneously. The screen will display "01"
and up to three reset reminders.
3. Press the UP arrow button until 01 changes to 06. The
number 4 (the default setting) will be displayed next to it.
4. Press the rightmost soft key and then press the UP arrow
button until the desired number of time periods is shown.

6. Close the thermostat door.
DAYLIGHT SAVINGS TIME — The thermostat will auto-
matically change the clock according to daylight savings time

on the upper left of the screen. For important safety reasons, do
not change a UV light; ask your dealer to replace the UV light.

press and hold the DONE button for about 3 seconds.
Outdoor Temperature Display —
automatically displays the outdoor temperature when the ther-
mostat door is closed if a valid sensor has been wired to the
thermostat.
Auto Changeover —
five modes: heat, cool, Em heat (heat pump version only), heat
cool (auto mode) and off. When the mode selection is auto
mode, the system is allowed to switch from heating to cooling
or from cooling to heating to maintain the temperature set
points.
Smart Recovery —
tions the space from one temperature period (occ, occ2, occ3,
unocc) to the next so that the space temperature matches the
temperature set point at the start of each time period. This
means, for example, that if the unocc period temperature set-
ting is lower than the period that precedes it, then the thermo-
stat will start cooling down the space before the beginning of
the scheduled unocc period. The thermostat does this at an en-
ergy efficient rate. This not only helps make the space as com-
fortable as possible, it also makes thermostat usage more cost
effective.
Power Outage —
thermostat will not need to be reprogrammed. The settings are
retained in memory.
