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.

any overhang. Choose a location
protected from direct sunlight.
2 Place sensor securely in bracket,
facing away from wall.

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.
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.

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.
• To add information from the USB
device to the thermostat, select
Load into Thermostat.
• To put thermostat information on
the USB device, select Save to USB.
When you replace a thermostat, you must reset the RedLINK accessories before
connecting them to the new thermostat. Follow the instructions below.
At the Portable Comfort Control:
Press and hold the blank space (or arrow) in the lower right corner
of the screen until the display changes (hold for about 4 seconds).
Press REMOVE, then YES to disconnect the old thermostats. To
reconnect the thermostat, go to Step 4.3.
At the Indoor Sensor, RedLINK Internet Gateway, Entry/Exit
Remote, Vent-Filter Boost Remote or TrueSteam Wireless
Adapter:
Press and hold the CONNECT button on the accessory until the
status light glows amber (hold for about 10 seconds). To reconnect
the thermostat, go to Step 4.3.
At the Equipment Interface Module (EIM):
Press and hold the CONNECT button on the EIM until the CON-
NECTED LED glows amber (hold for about 10 seconds). Follow the
prompts on the screen to connect the new thermostat to the EIM.
