the thermostat as either programmable (P) or non-programma-
ble (nP). Selections are P and nP. The default is P.
OPTION 25 — NUMBER OF PROGRAMMABLE PERI-
ODS PER DAY — This selection allows the installer to con-
figure the thermostat for two or four periods per day. This se-
lection is not available if Option 24 has been set to nP to con-
figure the thermostat for non-programmable operation.
When set to 2, periods OCC and UNOCC are available.
When set to 4, periods OCC, OCC2, OCC3 and UNOCC are
available.
The default is 4.
OPTION 26 — MINIMUM COOLING SET POINT —
This selection allows the installer to configure the minimum
cooling set point that the user is allowed to set. The range takes
into account the value of the adjustable deadband Option 11.
The range is 50 to 90 F plus the deadband. The default is 55 F
(based on the adjustable deadband default of 5).
OPTION 27 — MAXIMUM HEATING SET POINT —
This selection allows the installer to configure the maximum
heating set point. The range is based on the adjustable dead-
band value Option 11. The range is 50 F to 90 F minus the
deadband.
The default is 85 F (based on the adjustable deadband de-
fault of 5).
OPTION 28 — UV LIGHT REMINDER — This selection
allows the installer to select the number of months after which
the UV Light icon will be displayed to indicate to the user that
it is time to call the contractor to have the UV light(s) replaced.
Selections available are OF (off), 6, 12, 18, 24, 30, 36, 42, and
48.
When set to OF (off), the UV light reminder is turned off
and will never be displayed.
When set to 6 through 48, this is the number of months after
which the UV light reminder will be displayed.
The default is OF (off).
OPTION 29 — SERVICE REMINDER — This selects the
number of months after which the Service icon will be dis-
played.
When set to OF (off), the service reminder is disabled and
will never be displayed.
When set to 1 through 24, this is the number of months after
which the Service icon will be displayed.
The default is OF (off).
OPTION 30 — UNUSED
OPTION 31 — DAYLIGHT SAVINGS TIME CONFIGU-
RATION — This selection allows the installer to set the ther-
mostat to automatically change by one hour on the specified
daylight savings day, month, and week.
When set to OF (off), the Daylight Savings Time Function
is disabled.
The first time the UP or DOWN button is pressed, the value
of this selection changes from OF (off) to 1. When 1 is dis-
played, the days of the week and clock digits will be turned on.
The installer must set the start date (Spring) for Daylight Sav-
ings Time by setting the day of the week by selecting the ap-
propriate triangle icon next to the days of the week, the month
of the year will be set in the clock hours location (range 1 to 6)
and the week of the month will be set in the clock minutes loca-
tion. The week of the month selections will be F, 2, 3, 4, and L
for First, 2nd, 3rd, 4th, and Last. So for the first Sunday in
April, the display would show SUN, 4, F.
When 2 is displayed, the installer will then choose the end
date for daylight savings time (Fall) which will be a month
range of 7 to 12.
To activate the function, the installer changes the “2” by
pressing the up button and “On” is displayed. The setting
should be left “On” to enable the Daylight Savings Time func-
tion. Default is On.
OPTION 32 — UNUSED
OPTION 33 — SINGLE OR TWO-PIECE INSTALLA-
TION — This configuration allows the thermostat to compen-
sate for the amount of heat generated by the electronics to al-
low more accurate sensing of the temperature sensor. The
amount of heat compensation will be different between single
installation and two-piece installation. The range is 1P or 2P.
When set to 1P, the installation is single piece. When set to
2P, the installation is two separate pieces. The default is 2P.
OPTION 34 — OAT/SRTN TERMINALS FOR OAT OR
LAT SENSOR — This configuration will allow the installer
to configure the OAT/SRTN terminals for either an outdoor air
sensor input or a leaving air temperature sensor input. The
range is od or LA.
When set to od, the sensor connected between the OAT and
SRTN terminals is sensing outdoor-air temperature. If the sen-
sor is valid, the outdoor-air temperature is shown on the display
when the door is closed. If the sensor is invalid but required for
proper thermostat operation, a “–” will be displayed in the out-
door air sensor location when the door is closed.
When set to LA, the sensor connected between the RRS and
SRTN terminals is sensing leaving-air temperature. The LAT
temperature will be shown in the outdoor-air temperature loca-
tion on the display when the installer is viewing/setting Option
34. The LAT temperature will not be displayed to the user dur-
ing normal thermostat operation.
The default is od.
OPTION 35 — EMERGENCY HEAT MODE AVAIL-
ABILITY — The configuration allows the installer to turn on
or off Emheat (emergency heat) mode as a mode selection. The
range is OF (off) or On.
When set to On, the Emergency Heat mode is an available
mode selection. When set to OF, the Emergency Heat mode is
not an available mode selection. The default is On.
OPTION 36 — FAN SELECTION DURING OCCUPIED
PERIODS — This selection is not available if the thermostat
has been configured for non-programmable operation. The
range is Au or On.
When set to On, the fan will operate continuously during
occupied periods (OCC, OCC2 and OCC3). When set to Au,
the fan will operate only when the equipment is energized dur-
ing occupied periods.
NOTE: The Au selection is a violation of the ASHRAE 90.1
and Title 24 but is a feature of the thermostat for building own-
ers that mandate auto fan operation during occupied periods
for energy conservation purposes. The default is On.
OPTION 37 — FAN SELECTION DURING UNOCCU-
PIED PERIODS — This selection is not available if the ther-
mostat has been configured for non-programmable operation.
The range is Au or On.
When set to On, the fan will operate continuously during
the unoccupied period (UNOCC). When set to Au, the fan will
operate only when the equipment is energized during the unoc-
cupied period. The default is Au.
OPTION 38 — MAXIMUM TEMPORARY HOLD FOR
HOURS — This selection is not available if the thermostat has
been configured for non-programmable operation. The range is
OF (off), or 1 to 6.
