When the thermostat detects the humidity percentage is above the setpoint for dehumidification, and heating or cooling is not on, the thermostat will force the compressor to run with the fan, thus reducing moisture in the air. The green LED will blink once every eight seconds to indicate this is taking place. This feature will also allow you to adjust the cooling overshoot of the setpoint, from
° For Example: If the cooling overshoot is compressor and fan to dehumidify the air.

Page 13.1
Installing the Remote Sensors
The Remote Sensor measures indoor air temperature and sends this information to the thermostat; it measures temperature with a range of
32 to 99 F.
The Remote Sensor is equipped with an OVERRIDE button which will place the thermostat into the override mode for up to four hours (see page
5.1).
The Remote Sensor should be connected to the thermostat using solid conductor CAT 5, CAT 5e, or CAT 6 type network communication cable.
This is an unshielded cable with four twisted pairs of 24 gauge solid wire;
DO NOT use stranded cable. The cable length should not exceed 250 feet. If less than 75 feet of cable is required to connect the thermostat to the Remote Sensor, a three conductor thermostat cable (18-24 gauge) may be used; this cable is NOT suitable for any length greater than 75 feet.
IMPORTANT: Do no use shielded wire. Do not run sensor wiring in
13
ference may cause the sensor to give incorrect temperature read-
Ings.
See the Remote Sensor instructions for further details.
Page 13.2
Controlling or Reading the
Remote Temperature (RS

)
The thermostat may be programmed to only READ the remote sensor, or to CONTROL to the remote sensor. Refer to Advanced Setup step
#21, below.
Read Only Sensor (RS1): If step #21 is set to only READ to the
remote sensor, this temperature may be viewed by pressing the
OUTDOOR button on the thermostat and then pressing the
MODE button (see page 4.2).
Control Sensor (RS1): If step #21 is set to CONTROL to the remote
sensor, the thermostat will ignore the reading of its internal
temperature sensor and only display the temperature reading from
the remote sensor. The degree icon on the thermostat will blink
once per second to indicate that a remote sensor reading is being
displayed.

Random Start Operation
This feature causes a 2 to 30 second delay before energizing the thermostat outputs after any of these events:
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.
Closure of the Dry Contact to force Heat, Cool or Auto Modes:
If step #24 (page 14.3) is programmed for Override, 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 #23, page 14.2). This delay helps to keep
multiple thermostats from energizing their outputs each time the
Dry Contact is used.

Section 21
Warranty
One-Year Warranty - This Product is warranted to be free from defects in material and workmanship. If it appears within one year from the date of original installation, whether or 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.
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.
