PROGRAMMING TIPS
If only the Occupied 1 period is selected in the first programming step (page 6.2), Occupied
2 & 3 programming steps are skipped. Furthermore, if Occupied 2 is selected, Occupied 3
programming steps are skipped.
Heat & Cool setpoints for Occupied 1 are the same for every day of the week. If desired,
Heat & Cool setpoints for Occupied 2 & 3 can be adjusted differently for each day of the week.
If the start time is set later in the day than the stop time, the program will run from the start
time to midnight and from midnight to the stop time on the same day. For example: 9pm start,
8am stop, on Monday. In this example the program will run from 12am Monday to 8am Monday
and again from 9pm Monday to 12am Tuesday.
Unoccupied Operation: The unoccupied settings take effect at all times when: (1) the program is
on and (2) the current time is outside a preset occupied period. For this reason start and stop
times are not necessary for unoccupied time periods.
If the same start and stop times are programmed for an occupied period, then it will run
24 hours.
If one occupied period starts and stops within another occupied period the lower occupied # has
priority. For example: If Occupied 3 is programmed to be on 24 hours, and Occupied 2 is
programmed to run that day, then the Occupied 2 setting will take over for Occupied 3 between
Occupied 2 start and stop times.
After programming for all seven days is complete, press the PROGRAM button to
leave the Setup screens. If no buttons are pressed, the display will leave the setup
screens after 30 seconds.

Installing the Remote SensorsInstalling the Remote Sensors
Up to eight wired or wireless remote sensors may be installed on the
thermostat (RS1) to control the temperature in other rooms. If more
than one sensor is connected to (RS1) the thermostat will average the
sensors to determine the displayed temperature reading. One wired or
wireless remote sensor may be installed to read the outside temp-
erature (RS2). If a sensor(s) is connected to RS1 and is programmed
to control the thermostat, the degree icon on the thermostat will blink
once per second to indicate that a remote sensor reading is being dis-
played. The wired sensor can be connected to the thermostat with up
to 150’ of 18 ga., 300’ of 20 ga., or 450’ of 22 ga. unshielded, therm-
ostat wire. If multiple sensors are wired to the thermostat, then the
total wiring distance of the furthest sensor should be used in determin-
ing the appropriate wire gauge. The wired sensor can be connected to
the thermostat using a two or three wire installation. If a two wire instal-
lation is required, then RS+5 must be connected to RSGND (see below).
This wire MUST be completely separated from the thermostat
or any other control wiring and must NOT be in the same
conduit as high voltage wiring.

Random Start OperationRandom Start Operation
This feature allows a 2 to 30 second delay before energizing
the thermostat outputs after any of these events:
16
Loss of Power to the thermostat: When power to the thermostat
is interrupted and then restored, Random Start will lockout the
outputs of the thermostat for a random amount of time. This
delay helps to keep multiple thermostats from energizing their
outputs at the same time after a power outage.
Changing from an Unoccupied time period to an Occupied
time period: If the thermostat is running in the Program On mode
and the start time for an Occupied period forces the thermostat
from Unoccupied to Occupied 1, Random Start will lockout all
outputs of the thermostat for a random amount of time. This
delay helps to keep multiple thermostats from energizing their
outputs at the same time each day.
Closure of the Dry Contact to force Occupied 1 time period:
If step #41 (previous page) is programmed for Occupied 1, then
Random Start will lockout all outputs of the thermostat for a
random amount of time when a Dry Contact closure occurs
(depending on step #40). This delay helps to keep multiple
thermostats from energizing their outputs each time the Dry
Contact is used.
Sensing of a light source by the Light Sensor to force
Occupied 1 time period:
If step #42 (page 17.2) is programmed YES for Light Activated
operation, Random Start will lockout the outputs of the thermostat
for a random amount of time when a light source forces the
thermostat into Occupied 1. This delay helps to keep multiple
thermostats from energizing their outputs each time the lights are
turned on.

How to Use the Energy Save FeatureHow to Use the Energy Save Feature
If the thermostat is configured to be programmable (Section 4), and
Energy Save has been selected in step #43 (below), the room will
attempt to reach the selected comfort temperature at the exact time
programmed into the thermostat. Energy Save, or more commonly
known as Smart Recovery, only works when the thermostat enters
Occupied 1 from Unoccupied. For example, if the Unoccupied
program is set for 6pm at 55°F heating and 85°F cooling, and the
Occupied 1 program is set for 8am at 72°F heating and 75°F cooling,
the thermostat will turn the system on before 8am in an effort to bring
the temperature to its correct setting at exactly 8am.
The P374-2900 learns from experience, so please allow 4-8 days
after a program change or after initial installation to give Energy Save
time to adjust to local weather, the construction of your business, and
your heating and cooling system.

THIS WARRANTY DOES NOT INCLUDE LABOR OR OTHER COSTS incurred for diagnosing,
repairing, removing, installing, shipping, servicing or handling of either defective parts or
replacement parts. Such costs may be covered by a separate warranty provided by the installer.
THIS WARRANTY APPLIES ONLY TO PRODUCTS IN THEIR ORIGINAL INSTALLATION
LOCATION AND BECOMES VOID UPON REINSTALLATION.
LIMITATIONS OF WARRANTIES – ALL IMPLIED WARRANTIES (INCLUDING IMPLIED
WARRANTIES OF FITNESS FOR A PARTICULAR PURPOSE AND MERCHANTABILITY) ARE
HEREBY LIMITED IN DURATION TO THE PERIOD FOR WHICH THE LIMITED WARRANTY
IS GIVEN. SOME STATES DO NOT ALLOW LIMITATIONS ON HOW LONG AN IMPLIED
WARRANTY LASTS, SO THE ABOVE MAY NOT APPLY TO YOU. THE EXPRESSED
WARRANTIES MADE IN THIS WARRANTY ARE EXCLUSIVE AND MAY NOT BE ALTERED,
ENLARGED, OR CHANGED BY ANY DISTRIBUTOR, DEALER, OR OTHER PERSON
WHATSOEVER.
ALL WORK UNDER THE TERMS OF THIS WARRANTY SHALL BE PERFORMED DURING
NORMAL WORKING HOURS. ALL REPLACEMENT PARTS, WHETHER NEW OR
REMANUFACTURED, ASSUME AS THEIR WARRANTY PERIOD ONLY THE REMAINING
TIME PERIOD OF THIS WARRANTY.
THE MANUFACTURER WILL NOT BE RESPONSIBLE FOR:
1. Normal maintenance as outlined in the installation and servicing instructions or owner ’s
manual, including filter cleaning and/or replacement and lubrication.
2. Damage or repairs required as a consequence of faulty installation, misapplication, abuse,
improper servicing, unauthorized alteration or improper operation.
3. Failure to start due to voltage conditions, blown fuses, open circuit breakers or other
damages due to the inadequacy or interruption of electrical service.
4. Damage as a result of floods, winds, fires, lightning, accidents, corrosive environments or
other conditions beyond the control of the Manufacturer.
5. Parts not supplied or designated by the Manufacturer, or damages resulting from their use.
6. Manufacturer products installed outside the continental U.S.A., Alaska, Hawaii, and
Canada.
7. Electricity or fuel costs or increases in electricity or fuel costs for any reason whatsoever
including additional or unusual use of supplemental electric heat.
8. ANY SPECIAL INDIRECT OR CONSEQUENTIAL PROPERTY OR COMMERCIAL
DAMAGE OF ANY NATURE WHATSOEVER. Some states do not allow the exclusion of
incidental or consequential damages, so the above may not apply to you.
This warranty gives you specific legal rights and you may also have other rights which may vary
from state to state.

not actual use begins on that date, that the product does not meet this warranty, a new or
remanufactured part, at the manufacturer’s sole option to replace any defective part, will be
provided without charge for the part itself provided the defective part is returned to the
distributor through a qualified servicing dealer.
