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.

HUM JUMPER SETTING

If the jumper for MISC1, MISC2, or MISC3 is set to HUM, the corresponding MISC screw terminal on the backplate will control a humidification system.

HUMIDIFICATION OPERATION - SECTION 8

If your HVAC unit is equipped with a humidification system and the Humidity

Module (sold separately) has been installed, the thermostat will provide power to the MISC1, MISC2, or MISC3 terminal of the thermostat when the humidity in the home falls below the humidity setpoint you have chosen. The value for this setpoint ranges from 0% to 60%. If no humidity is desired or if a humidification system has not been installed, set the value to 0%.

DEHUM JUMPER SETTING

If the jumper for MISC1, MISC2, or MISC3 is set to DEHUM, the corresponding MISC screw terminal on the backplate will be connected to the dehumidification terminal of a furnace board.

NOTE: Not all furnaces have a dehumidification terminal.

DEHUMIDIFICATION OPERATION - SECTION 9

If your HVAC unit is equipped with a dehumidification system the thermostat will operate in one of two ways.

1) Normally Closed (NC): The thermostat will de-energize the MISC1, MISC2,

or MISC3 terminal of the thermostat (this MISC terminal is connected

to the DEHUM terminal on your furnace) to allow the fan to run in low

16

speed when the humidity in the home is above the dehumidify setpoint you

have chosen and there is a call for 1st stage cooling.

2) Normally Open (NO): The thermostat will energize the MISC1, MISC2, or

MISC3 terminal of the thermostat (this MISC terminal is connected to the

DEHUM terminal on your furnace) to allow the fan to run in low speed when

the humidity in the home is above the dehumidify setpoint you have chosen

and there is a call for 1st stage cooling.

Section 21

Five-Year Warranty - This Product is warranted to be free from defects in material and workmanship. If it appears within five 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.
