Using Your Air Conditioner to Dehumidify
If Cool to Dehumidify is on and the Humidity Module is installed,
the thermostat has the ability to initiate a cooling cycle for advanced
dehumidification operation. 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
0° to 5° (adjustable in step #11). For Example: If the cooling overshoot is
set for 3°F and the cooling setpoint is set for 74°F, then as long as the room
temperature reads between 71°F and 74°F this feature will energize the
compressor and fan to dehumidify the air.

SECTION 13
Dual Fuel Operation
Programming the Thermostat to
Operate a Dual Fuel System
Advanced Setup step #21 (next page) allows this thermostat to be
configured to control two heat sources for Dual Fuel operation.
Dual Fuel systems utilize an outdoor temperature sensor. When the
outdoor temperature is at or below the Changeover Balance Point,
step #22 (next page), the primary heat source is ‘locked out’ and
the heat source connected to W3 is energized. There is a three
degree deadband from the Changeover Balance Point, which
requires the outdoor temperature to rise three degrees before
switching back to the primary heat source. If an outdoor
temperature sensor (RS2) is not installed and the thermostat is
programmed for Dual Fuel operation, 1st and 2nd stage heating is
locked out and only W3 will be energized (see page 13.3 for
detailed information).

For outdoor sensor (RS2) wiring please see page 16.2 of this
manual and for the thermostat jumper setting and wiring
instructions please refer to page 5.6 of the Installation

This table illustrates the outputs that will be energized on a call for
first, second and third stage heating, based on the programming in
setup steps 21 and 22 (see previous page) and the HP/GAS jumper
setting on page 12.2.
For example, in the first section of this matrix the thermostat has
been programmed to operate a Heat Pump Dual Fuel system based
on a Balance Point. The Outdoor Temp is warmer than the Balance
Point (Outdoor Temp > Balance Point). This means that 1st stage
heating will energize G and Y1, 2nd stage heating will energize W2
and 3rd stage heating (W3) is unavailable. The Reversing Valve
may, or may not be energized, depending on how it has been programmed (see note).

Page 16.1
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 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 the
same conduit as the 24VAC thermostat wiring. Electrical interference
may cause the sensor to give incorrect temperature readings.
16
Page 16.2
Controlling or Reading the
Remote Temperature (RS1)
The thermostat may be programmed to only READ the remote sensor,
or to CONTROL to the remote sensor. Refer to advanced setup step
#38, below.
Read Only Sensor (RS1): If step #38 is set to only READ to the
remote sensor, the thermostat will not use this sensor for
temperature control. This sensor may be viewed by pressing the
OUTDOOR button on the thermostat and then pressing the MODE
button.
Control Sensor (RS1): If step #38 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.

Energy Save Operation
How 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 the
Morning mode from the Night mode. For example, if the Night
program is set for 11pm at 65°F heating and 85°F cooling, and the
Morning program is set for 6am at 72°F heating and 75°F cooling, the
thermostat will turn the system on before 6am in an effort to bring the
temperature to its correct setting at exactly 6am.
The T1900 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 home, and
your heating and cooling system.

Configuring the Jumpers
For additional flexibility, your thermostat has three configurable
outputs. These outputs are designed to have different functions
depending on how the jumpers are set (below).
Each output, labeled MISC1, MISC2, and MISC3 may be set for one
of the five choices available.
In the diagram below, the MISC3 jumper has been set for HUM
(humidification) operation, the MISC2 jumper has been set for DEHUM
(humidification) operation, and the MISC1 jumper has been set for
PROG (programmable) operation.

W3 JUMPER SETTING
If the jumper for MISC1, MISC2, or MISC3 is set to W3, the corresponding MISC screw terminal
on the backplate will control a third stage of heat.
W3 MULTI-STAGE OPERATION EXPLAINED - Page 14.4
The 3rd Stage of Heat is turned on when:
(A) The 1st and 2nd stages have been on for the time required (steps 28
and 29, page 14.6). It is adjustable from 0-60 minutes and the default
And
is two minutes.
(B) The temperature from the setpoint is equal to or greater than: the setpoint plus the 1st stage deadband (step #25, 14.5), plus the 2nd stage
deadband (step #26, 14.5) plus the 3rd stage deadband (step #27,
14.5). This 3rd stage deadband is adjustable from 0-10 degrees and
the default is two degrees.

PROG JUMPER SETTING
If the jumper for MISC1, MISC2, or MISC3 is set to PROG, the corresponding MISC screw
terminal on the backplate will control a pilot relay or other accessory.
PROGRAMMABLE OUTPUT - SECTION 15
This jumper setting allows the MISC outputs to control a pilot relay by time,
temperature, or a signal from the Internet/Phone. The following are three
possible scenarios:
By Time: A device that requires a start and stop time. For example, an
21 exterior lighting system that needed to be energized every day between
the hours of 8pm and 1am.
By Temperature: An exhaust fan that needs to energize whenever
the temperature from RS1 rises above 90 degrees F.
By Remote: Remotely arming a security system through the web or phone.
Page 21.3
Explanation of Jumper Settings (continued)
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 9
If your HVAC unit is equipped with a humidification system 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 10
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 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.
21
Page 21.4
Explanation of Jumper Settings (continued)
Y2 JUMPER SETTING
If the jumper for MISC1 is set to Y2 the MISC1 screw terminal on the backplate will control a
second stage of cooling.
Y2 OPERATION - Page 14.4
Control up to two Cool stages.
The 2nd Stage of heat or cool is turned on when:
(A) The 1st Stage has been on for the time required (step #28,
page 14.6). It is adjustable from 0-60 minutes and the default
is two minutes.
And
(B) The temperature spread from the setpoint is equal to or greater
than: the setpoint plus the deadband (step #25, page 14.5), plus
the 2nd deadband (step #26, page 14.5). This 2nd deadband is
adjustable from 0-10 degrees and the default is two degrees.

SECTION 26
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.
