Installing the equipment interface module (EIM)

NOTE: If an EIM is mounted inside a metal cabinet, 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.

NOTE: When installing multiple

thermostats and EIMs, mount the
EIMs at least 2 feet apart for best
RedLINK performance.

1.1 Mount EIM.
Mount the EIM near the HVAC
equipment or on the equipment
itself.

Use screws and anchors as
appropriate for the mounting
surface.

1.2 Wire EIM as shown.
Refer to the table and wiring diagrams on pages 3-5.

NOTE: If you are installing discharge and return air sensors, refer to the mounting

instructions in the Alerts and Delta T Diagnostics Installation Instructions packed
in the kit.

Mounting outdoor and indoor sensors

Mounting an outdoor sensor

1 Mount the sensor on a vertical

exterior wall, at least 6 inches below
any overhang. Choose a location
protected from direct sunlight.

2 Place sensor securely in bracket,

facing away from wall.

12

Mounting an indoor sensor

1 Remove the wallplate and mount

it 4 to 6 feet above the floor on an
interior wall. Drill 3/16-inch holes for
drywall, 7/32-inch for plaster.

2 Attach sensor securely to wallplate

as shown.

Indoor sensor operation

Temperature control

The thermostat can be set to respond to its
internal temperature sensor, or to an optional
remote indoor sensor. If multiple sensors are
selected, the thermostat will respond to an
average of temperatures detected at each
sensor.

If optional remote indoor sensors are
installed, you can choose which sensor you

Using a USB device for setup, data logs and software upgrades

Use a USB device to save set up time by loading Installer Setup settings, Dealer
Information, Holiday Schedules, and Custom Reminders to multiple thermostats.
For troubleshooting help, you can save the thermostat Data Logs (Alerts Log, User
Interactions Log and Performance Logs) to a USB device - then view them on your
computer. Also use the USB device to upgrade the thermostat software.

• Visit http://thermostatsetup.honeywell.com to enter your dealer information
and contractor logo or load new thermostat software.

• After setup is complete, save Installer Setup, Holiday Schedules, and Custom
Reminders to a USB device.

To use the USB device in the thermostat:

1 Slide USB device into the bottom of

thermostat.

2 Select the item to load or save.

3 Follow the prompts on the screen for the

item you selected.
