SmartTemp Explanation
The SmartTemp feature can save up to 30% or more in operating
costs over standard thermostats. SmartTemp gives you almost the
same energy savings as thermostats with motion detectors and/or
door interlocks at a much lower cost for both the thermostat and
installation. No external wiring is required for this feature.
HOW IT WORKS:
T h e t h e r m o s t a t h a s a b u i l t - i n c l o c k . T h e
thermostat can automatically go into an unoccupied setting up to four
times a day(default unoccupied settings are 78 degrees and 68
degrees). The default times for unoccupied are 8:00 AM, 12:15
PM, 3:00 PM, and 7:00PM. The rationale for these times are:
8:00 AM: Most guests are expected to leave the room by 8:00
AM and either check out or be gone until check-out time.
12:15 PM: The room will not likely be occupied between the
check-out and check-in times.
3:00 PM: Housekeeping staff usually place the thermostat into
an occupied mode while cleaning the room.
7:00 PM: Guests typically leave for dinner and the room
remains unoccupied until they return to retire for the evening.
The thermostat only displays the setpoint that the hotel guest has
selected. When the thermostat is in an unoccupied state, only room
temperature is displayed, which the guest will assume is the setpoint
temperature.
The number of time periods, their start times, and the unoccupied setpoints can be set by hotel management to maximize
savings of operating costs and customer comfort.
Customer complaints are virtually nonexistent with thermostats
equipped with the SmartTemp feature, compared to motion sensor and
door interlock thermostats.
Page 6
Page 8
SmartTemp Explanation
Surveys have shown that even though a hotel can expect to
realize an estimated 30% energy savings in heating, cooling and fan
costs, the hotel guest is unaware that the thermostat is automatically
entering an “unoccupied” state several times throughout the day.
The reason for this is that while the hotel guest is in the room, he or
she always has complete control of the actual temperature. If the
hotel guest happens to notice that the thermostat has entered into
“unoccupied” (which is rare), he or she usually assumes that a maid,
bar service, or turn-down service person has been in the room and
changed the setting.
Page 7
Page 9
Programming Occupied & Unoccupied Periods
To maximize energy savings, the program allows for a day to be broken into
four time periods with every day of the week sharing the same program. For each
time period, you may choose to have a unique setpoint or simply use the
unoccupied setpoints. If four different time periods are not required, then multiple
time periods may be set to the same start time.
SMARTTEMP - When a time period is set to OFF, unoccupied settings will be
used for that period. During unoccupied operation, the large numbers change
from displaying the setpoint to displaying the room temperature and the degree
icon will flash. If a guest enters the room and presses the WARMER or COOLER
button, the room temperature will be accepted as the setpoint and then can be
raised or lowered. This setpoint will remain in effect until the start of the next time
period. This enables the guest to maintain control over the room temperature
(within setpoint limits), while maximizing energy savings.

CLOCK BACKUP - In the event of a power
loss, the
thermostat’s internal clock will continue to keep
proper time for a minimum of 48 hours without
external power or batteries. The T0051FS stores
the time at which power is removed and resumes
timekeeping from that point, upon power restoration.
2 STAGE OPERATION - The 2nd Stage of Heat or Cool is
turned on when (1) the 1st Stage has been on for a
minimum of two minutes, and (2) the temperature spread
from the setpoint is equal to or greater than: the setpoint
plus the deadband, plus 2 degrees.

MINIMUM HEAT/COOL SETPOINT DIFFERENCE - The Heat

# 16, on page 16. This minimum difference is enforced
during Auto-changeover and Program On operation.
DRY CONTACT SENSE - N.O.=Normally Open. N.O. setting

During Emergency Heat, the thermostat will turn on the fan
and the 2nd stage of heat when there is a demand for heat,
which locks out the 1st stage compressor.
During Emergency Heat only OFF and HEAT are available.
Exiting Emergency Heat is the same as entering.
DRY CONTACT LATCH SCHEME - If Latch OFF is selected,
the thermostat runs normally. If Latch ON is selected, the
thermostat will ‘wait’ in unoccupied settings. A
momentary closure of the dry contact will put the thermostat
into the appropriate period, (Morning, Day or Evening)
for 30 minutes.

If the contact closure occurs during Night then the
thermostat will remain in Night settings until the Morning
period. Then it will return to unoccupied. This is used in
a hotel room with a motion detector to allow for comfort
settings during sleep periods without movement.

KEYPAD LOCK - To prevent unauthorized use of the thermostat,

INTERNAL SETPOINT LIMITING - The display setpoint(s)
may be set further than the thermostat’s internal
limits.
For example: Internal setpoint limits set to 77
maximum and 69 minimum:
If the COOLER button is pressed to bring the displayed
setpoint down to 35 degrees, internally the thermostat
will clamp the Cool setpoint to 69 degrees minimum and
not go any lower, but the display would show 35 degrees.

About Advanced Features & Operation
DUAL SETPOINT BEHAVIOR - The adjustable setpoint range
is: 35 - 99 degrees Fahrenheit and 7 - 35 degrees
Centigrade. When in the modes Heat or Cool, this
adjustable range is unhampered.
When adjusting any Auto mode, including programming
Occupied and Unoccupied periods, the thermostat will not
allow the Heat setpoint to get closer to the Cool setpoint
than the value programmed as the minimum difference in
step 16, page 16.
When entering the Auto mode from Cool, the Heat and
Cool setpoints will remain spread apart by the amount
that they were adjusted, prior to entering Auto.
For example: If the Cool setpoint was set to 80 while
in the Cool mode and the Heat setpoint was adjusted to
70 while in the Heat mode, upon entering the Auto mode
the Cool and Heat setpoints would be 80 and 70. Both
setpoints would then move up and down together, (in this
example spread by 10 degrees), by pressing the WARMER
or COOLER buttons. To move the Heat and Cool setpoints
closer together, enter the Cool or Heat mode by pressing
the Mode button, then adjust the setpoint(s) closer together.
Heat is limited to how close it can come to Cool by step 16,
page 16.
ELECTRIC HEAT - Selecting Electric Heat ON, step 13,
page 15, will cause the thermostat to turn on the fan
immediately any time there is a heat demand. Since all
gas furnaces control the fan, this feature should be off
unless the heater is only electric.
