Interstage Differential:
Comfort:
The thermostat keeps the indoor temperature within 1
degree of the setpoint (droop less control). The thermostat
turns on stage 2 when the capacity on stage 1 reaches 90%.
When the interstage differential is set to 1.0 or higher, the ther-
mostat stages the equipment based on how far the indoor
temperature is from the setpoint (ISU 303 to 309). See
page 27 for more information.
Clock Accuracy: 1 minute per month at 77 °F (25 °C). ± 2
minutes per month over the operating ambient temperature
range.
Mounting Means:
Thermostat mounts directly on the wall in the living space
using mounting screws and anchors provided. Fits a horizontal 2 x 4 in. junction box.
Equipment Interface Module (EIM) mounts on HVAC equip-
ment or on a wall in the equipment room.

Guidelines for Installing RedLINK Devices
— When installing more than one Thermostat and Equipment
Interface Module, mount the Equipment Interface Modules
at least 2 feet apart for best RedLINK performance. No
minimum distance is required between the Thermostats if
the Thermostat is linked to an Equipment Interface Module.
— When the Thermostat is wired directly to the equipment (No
Equipment Interface Module and No TrueZONE Wireless
Adapter), mount the Thermostats at least 2 feet apart for
best RedLINK performance.
— To determine if a RedLINK device will communicate
properly in the installed location, during the connection
process, press and quickly release the connect button on
the RedLINK device at the desired mounting location
. If the
RedLINK device connects, then it will work reliably during
normal operation. If the RedLINK device does NOT
connect, try a new location. During the connection process,
the signal is sent at low power and during normal operation
the signal is sent at high power.
— To connect a RedLINK device, make sure to press and
quickly release the connect button on the RedLINK device.
Press and holding the connect button down too long will not
allow the device to connect.
— If you link the Thermostat to the TrueZONE Wireless
Adapter, you will NOT be able to do the following: control
humidification, dehumidification or ventilation, setup a
program schedule remotely from a computer, smart phone
or tablet, work with the Wireless Indoor Sensor, Entry / Exit
Remote or the Vent and Filter Boost Remote. To use these
features, wire the Thermostat directly to the zone panel or
use an Equipment Interface Module.
— If you are using a RedLINK device from a previous
installation, you must reset the device first before you reconnect it to the new Thermostat/Equipment Interface
Module. See page 116 for more information.
Installing Equipment Interface Module (if used)
If no Equipment Interface Module is used, skip to “Selecting
Thermostat Location” beginning on page 11.
NOTE: If an EIM is mounted inside a metal cabinet, such
as a commercial rooftop unit, it is recommended
to use a THM4000R1000 Wireless Adapter for
extended wireless range. Mount the Wireless
Adapter outside the metal cabinet and connect to
the ABCD terminals at the EIM. The Wireless
Adapter functions as a remote antenna for the
EIM. After it is wired to the EIM, it automatically
takes over as the antenna for RedLINK communication. For best RedLINK performance, avoid
mounting the Wireless Adapter above the roof
deck or outside the exterior walls.
NOTE: If you install more than one thermostat and EIM,
the EIMs must be at least 2 feet apart for best
RedLINK performance.
The Equipment Interface Module (EIM) can be mounted
vertically on the HVAC equipment or on a wall in the equipment
room.
1. Mount the EIM near the HVAC equipment, or on the
equipment itself. Use screws & anchors as appropriate
for the mounting surface.
2. To wire the EIM, strip 1/4” insulation, then insert wires
(see Fig. 7). For wiring diagrams, see “Wiring” beginning
on page 117.

Wiring 24 Vac Common
• Single-Transformer System—Connect the common side of
the transformer to the C screw terminal of the EIM. Leave
the metal jumper wires in place between R, RC, and RH.
• Two-Transformer System—Connect the common side of the
cooling transformer to the C screw terminal of the EIM.
Remove the metal jumper wire between RC and RH.
Connect the hot side of heating transformer to RH and leave
the jumper wire between R and RC and connect the hot
side of cooling transformer to R or RC.

Selecting Discharge Air Temperature
Sensor Mounting Location
1. Mount the Discharge Air Temperature Sensor on the
supply duct in a location where the air is mixed well.
Mount the Discharge Air Temperature Sensor out of sight
of the A-Coil/Heat Exchanger when possible. See Fig. 8.
2. When possible, mount the Discharge Air Temperature
Sensor upstream of a Steam Humidifier, a Fan Powered
Humidifier or a Dehumidifier that is ducted to the supply.
See Fig. 9–10.
3. If space does not allow a Discharge Air Temperature
Sensor upstream of a Steam Humidifier or Fan Powered
Humidifier, mount the Discharge Air Temperature Sensor
downstream of the Humidifier. See Fig. 9.
4. If a Bypass Humidifier is installed, mount the Discharge
Air Temperature Sensor downstream of the Bypass
Humidifier. See Fig. 11–12.

Installing Discharge and Return Air Temperature Sensors
Use the following steps to mount the Discharge/Return Air
Sensors:
1. Attach plastic cover to the sensor probe.
2. Drill 1/4-inch hole for the sensor probe and mount it to
the ductwork with enclosed screws (see Fig. 13).
3. Connect wires to S1, S2, S3 or S4 terminals at the EIM.
4. Setup the S1, S2, S3 or S4 terminals in the Installer
Setup at the thermostat.

Selecting Thermostat Location
Install the thermostat about 5 ft. (1.5m) above the floor in an area
with good air circulation at average temperature. See Fig. 14.
Fig. 14. Selecting thermostat location.
Do not install the thermostat where it can be affected by:
— Drafts or dead spots behind doors and in corners.
— Hot or cold air from ducts.
— Radiant heat from sun or appliances.
— Concealed pipes and chimneys.
— Unheated (uncooled) areas such as an outside wall behind
the thermostat.
2. Position and level the wallplate (for appearance only).
3. Use a pencil to mark the mounting holes.
4. Remove the wallplate from the wall and, if drywall, drill
two 3/16-in. holes in the wall, as marked. For firmer
material such as plaster, drill two 7/32-in. holes. Gently
tap anchors (provided) into the drilled holes until flush
with the wall.
5. Position the wallplate over the holes, pulling wires
through the wiring opening. See Fig. 16.
6. Insert the mounting screws into the holes and tighten.

Deadband is the minimum separation between
heat and cool settings when the thermostat is
setup for Auto Changeover. For example, if the
deadband is set to 3° F and the cool setpoint
is 75° F, the warmest heat setpoint allowed
would be 72° F. If the heat setpoint is adjusted
above 72° F, it will automatically adjust the
cooling setpoint higher to maintain the 3° F
deadband.
When ISU 907 or ISU 910 (Dehum Over
Cooling Limit) is set to 1, 2, 3, 4 or 5 F, the
thermostat will not show the full Deadband
range. For example, if you set a Deadband of 3
F and an Over Cooling Limit of 2 F, the
minimum Deadband that you can select will
be 5 F. This prevents the heating system from
turning on when the thermostat over cools to
reach the dehumidification setting.
