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 week of the month. So for the
first Sunday in April, the display would show SUN, 4, F.
Press the soft key to change the 1 to a 2 to 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. “On” is then displayed. The setting
should be left “On” to enable Daylight Savings Time function.
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
SAT SENSOR — This configuration will allow the installer to
configure the OAT and SRTN terminals for either an outdoor
air, return air, or supply air temperature sensor input. The range
is od, rA or sA.
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 rA, the sensor connected to the OAT and SRTN
terminals is sensing return-air temperature (RAT). The RAT
temperature will be shown in the outdoor-air temperature loca-
tion on the display only when the installer is viewing or setting
this option. The RAT temperature will never be displayed to
the user during normal thermostat operation. This option is for
display only and is not used to control the sensor.
When set to sA, the sensor connected to the OAT and SRTN
terminals is sensing supply-air temperature (SAT). The SAT
temperature will be shown in the outdoor-air temperature loca-
tion on the display only when the installer is viewing or setting
this option. The SAT temperature will never be displayed to the
user during normal thermostat operation. This option is for dis-
play only and is not used to control the sensor.
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.
NOTE: In a non-heat pump application, if emergency heat
is off, the second stage of heat will show “heat on” and “2”
in the bottom right of the thermostat display.
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.
When set to OF, the thermostat set points can not be over-
ridden by the user.
When the “Follow Schedule” icon is shown and the user
changes the set point, the “temporary hold for” icon is dis-
played and the temporary hold timer is displayed in the clock
location. The starting value of this timer can be set from 1 to 6
hours. The user can decrement the timer value but can not in-
crement it beyond the value specified by this configuration.
The default is 2.
OPTION 39 — TEMPERATURE DISPLAY — This con-
figuration allows the installer to select either the set point tem-
perature or the space temperature to be displayed on the large
temperature display digits.
When the option St is chosen, the space temperature, as de-
fined by Option 05, is displayed using the traditional space
temperature digits on the LCD display. The current set temper-
ature is displayed using the normal set point display digits.
When SP is chosen, the current set point temperature is dis-
played using the traditional space temperature digits on the
LCD display. The normal set point display digits remain blank.
Space temperature is not displayed, but if a problem occurs
with the actual space temperature sensor, the characters "- -"
will be displayed instead of the set temperature to indicate that
the temperature sensor has an error.
NOTE: The "Actual Temp" icon is not displayed when the sen-
sor type is set to set point display (SP).
The default is St (Space Temperature).
OPTION 99 — RESET TO FACTORY DEFAULTS — Use
this capability to reset the control to “out of the box”
conditions.
When this option is selected, the configuration number (99),
appears on the left and the number 10 will appear on the right.
To perform the reset, first use the MODE button to move the
box from the 99 to the 10. Press and hold the DOWN button.
The 10 will start counting down toward zero. If the DOWN
IMPORTANT: All configuration settings, program set-
tings, clock, and calendar settings which have been manu-
ally entered will be lost and reset.
