set to OF, then Auto mode is not available. Allowable selections
are On and OF (off). The default is On.
OPTION 16 — CYCLES PER HOUR — This selection limits
the number of cycles per hour that the thermostat allows the sys-
tem to operate. Selections are 4, 6, 8.
When set to 4, the heating and cooling outputs will be ener-
gized no more than 4 times per hour. When an output is ener-
gized, it will not be energized again for 15 minutes.
When set to 6, the heating and cooling outputs will be ener-
gized no more than 6 times per hour. When an output is ener-
gized, it will not be energized again for 10 minutes.
When set to 8, the heating and cooling outputs will be ener-
gized no more than 8 times per hour. When an output is ener-
gized, it will not be energized again for 7.5 minutes.
The default is 4.
OPTION 17 — TIME BETWEEN STAGES — This selec-
tion determines the minimum number of minutes of equipment
operation on the highest compressor stage before allowing the
transition to the next logical stage. Available selections are 10,
15, 20, and 25 minutes.
NOTE: If the difference between the space air temperature and
set point results is a demand greater than three degrees, then the
staging timers are ignored and the equipment will stage up in 60-
second increments.
The default is 15 minutes.
OPTION 18 — BACKLIGHT CONFIGURATION — When
set to OF (off), the backlight will be lit for 10 seconds after a
button is pressed. After 10 seconds of no button presses, the
backlight turns off. When set to 1 through 5, the backlight will
normally be on and dim in appearance. The backlight brightness
becomes brighter when a button is pressed. After 10 seconds of
no button presses, the backlight will return to the dimmer level
until another button press occurs. The range of brightness is 1
through 5 with 5 being full brightness. Allowable selections are
OF (off) and 1 through 5. The default is 3.
OPTION 19 — DRY CONTACT — This option is not avail-
able if thermostat has been configured for non-programmable
operation. There are 3 available selections, OF, 1 and 2. When
set to OF, the dry contact is always de-energized.
When set to 1, the dry contact will be energized for the speci-
fied number of minutes per hour. This selection is programmable
by period. When this selection is changed from OF to 1, the peri-
od icons are shown and the minute segments of the clock display
are shown. The triangle icon next to the OCC period will be on
and a value between 0 and 60 will be shown in the minutes dis-
play. See the Dry Contact/Economizer Output section on page
13 for further explanation of dry contact configuration and use.
To change the period or minutes, press the soft key below the pe-
riod or minutes and then use the UP or DOWN buttons to change
to the desired value.
When set to 2, the dry contact will operate as a DEHUM re-
lay. This option is only available on the 33CS2PPRH-03 model.
There is a +1/–4% hysteresis around the dehumidification set
point to prevent rapid on/off cycling of the DEHUM output.
When configured for dehumidification, the Rc terminal must be
connected to one of the dry contact terminals (D1 or D2). This
provides power to energize the dehumidification terminal on the
cooling equipment when the dry contact is closed. See the Hu-
midity Control Features section on page 11 for more informa-
tion.
The default is OF (off) for 33CS2PP2S-03 thermostats and 2
for 33CS2PPRH-03 thermostats.
OPTION 20 — OUTDOOR-AIR TEMPERATURE OFFSET
ADJUSTMENT — This selection allows the calibration, or de-
liberate miscalibration, of the outdoor-air temperature sensor
reading. The selection ranges from –5 to +5 F (–2.8 to +2.8 C).
The default is 0.
NOTE: This configuration is only available if Option 34 is set to
od or if a valid sensor is connected.
OPTION 21 — KEYPAD LOCKOUT — The thermostats
are shipped with the keypad fully accessible. This option allows
the installer to limit access to the keypad. Selections are OF (off),
1, 2, 3, or cd. When set to OF, the user has full access to keypad.
When changed from OF to 1, 2, 3, or cd, an access code can be
entered to provide more security to the thermostat.
To set up an access a code for the thermostat, enter two sets of
numbers when"- --" is shown in the clock display. Press the but-
ton under the soft key for the first dash and use the UP and
DOWN buttons to enter in a number between 0 and 19. The sec-
ond set of dashes can be any number between 0 and 99. See
Fig. 13.
