Turning the Heating and Cooling System Off
—
To use the thermostat to turn the heating and cooling sys-
tem off, perform the following:
1. Open the thermostat door.
2. Press the MODE button until the display shows “off” in
the upper right corner.
3. Close the thermostat door.
Changing the Humidity Level —
Some thermostats
offer three humidity options: normal, auto, and off. This func-
tion is only available on 33CS2PPRH thermostats.
The thermostat is set at the factory for “normal humidify,”
which is a fixed humidity setting based on how much humidity
the user wants in the space. This humidity level remains
constant, regardless of the outdoor temperature. The user can
manually adjust the humidity level according to their own
preferences.
The second option, “auto humidify,” uses an outdoor tem-
perature sensor (if installed) to automatically adjust the indoor
humidity level according to the outside temperature.
The third option is to turn off the humidify/dehumidify
feature.
To change the fixed (constant) humidity setting for normal
humidify, perform the following procedure:
1. Open the thermostat door.
2. The “humidify” icon will be displayed at the bottom of
the screen when the operating mode is heat. The “dehu-
midify” icon will be displayed when the operating mode
is cool.
3. Press the soft key under the humidify or dehumidify
icons. The screen will display the current setting.
4. Press the UP or DOWN button to change the humidity
setting. It is factory set at 26% for humidify and 60% for
dehumidify. If there is too much condensation in the
space, set the value to a lower number. If the air is too dry,
set the value to a higher number. Humidity can be set to
between 10% and 46%. The dehumidify range is from
46% to 98%.
5. Close the thermostat door.
To change the humidity setting for auto humidify, perform
the following procedure:
1. Open the thermostat door.
2. The “humidify” icon will be displayed at the bottom of
the screen. Press the soft key under the humidify icon.
The screen will display the current setting.
3. Press the MODE button. An auto icon will appear at the
top of the screen. The current humidity reading and the
auto humidify set point will also be shown. The default
auto humidify set point is 5.
4. Press the UP or DOWN button to change the auto humid-
ify setting number (1 through 9). If there is too much
condensation on the windows, select a number lower than
5. If there seems to be a lot of static electricity, which of-
ten means the air is too dry, select a number higher than 5.
5. Close the thermostat door.
To turn off the humidify or dehumidify feature open the
thermostat door. Press the soft key under the humidify or dehu-
midify icons. Then press the MODE button until the screen dis-
plays OF. Close the thermostat door.
Using Emergency Heat —
Emergency heat should be
selected when it is desirable to heat the space with the auxiliary
heat only.
To set the thermostat to use emergency heat, perform the
following procedure:
1. Open the thermostat door.
2. Press the MODE button repeatedly until the arrow under
the button moves to the “Em heat” indicator on the
screen.
3. Close the thermostat door.
Advanced Programming —
The user can customize
several features of the thermostat. See Table 3.
Table 3 — Configuration Options
RESET REMINDERS — The thermostat will display when
it is time to change the UV (ultraviolet) light, change the filter,

the DONE button for about 3 seconds will clear all reminders.
This might not be desirable when multiple reminders are
shown.

vidual reminders, perform the following:
