1. Safety
NOTE: Use 18-gauge color-coded thermostat cable for
proper wiring. Shielded cable is not typically required.
Keep this wiring at least one foot away from large inductive
loads such as Electronic Air Cleaners, motors, line starters,
lighting ballasts and large distribution panels.

2 18-HD72D1-6
Failure to follow these wiring practices may introduce
electrical interference (noise) which can cause erratic
system operation.
All unused thermostat wire to be grounded at indoor unit
chassis ground only. Shielded cable may be required if the
above wiring guidelines cannot be met. Ground only one
end of the shield to the system chassis.

Ceiling Fan
Heat from the screen may be trapped
within the body of the Control by an
external top-down airflow source, such
as a ceiling fan.
The onboard thermistor may be biased
by this heat causing the displayed
indoor temperature to be elevated.
4. Installation
4.1 Location
The 824 is designed for installation in climate controlled
living spaces. Place the unit in a central location with good
circulation.
For proper temperature sensing, avoid exposing the 824 to
heat radiated from lamps, sun light, fireplaces or any other
radiant heat source.
Avoid locations close to windows, behind doors or alcoves
with poor air circulation, adjoining outside walls, or doors
that lead to the outside.
Select a location that prevents the 824 from being directly
exposed to air currents from supply registers or ceiling fans.
Mount the Control on a section of interior wall that does not
contain hot or cold water pipes or duct work.
Important: The 824 Control utilizes a 4.3” color touch
screen. This screen generates heat which is vented out
the top of the Control utilizing natural convection. If an air
source is directed at or from above, heat from the screen
can be trapped within the Control and can cause the indoor
temperature to be biased. (Refer to Figure 1 on page 4.)

4.2 Network Connections
To take advantage of the full range of features on the 824
Control, it should be connected to the Internet. This is
possible using either a wireless or a wired connection.
Wireless Connections
If the 824 Control will be connected to the Internet using the
built-in wireless feature, choose a mounting location that
ensures adequate signal strength from the Internet router.
Tips to Help Maximize Signal Strength:
— Do not mount the Control more than 30 feet from the
wireless router
— There should be no more than three interior walls
between the Control and the router.
— Do not mount the Control in areas where
electromagnetic emissions from other devices,
appliances or wiring can interfere with the Control’s
communication. (i.e. wireless phones, security
systems, wireless Internet cameras).
— Do not mount the Control in recessed areas,
near metal objects, or near structures. (i.e. doors,
appliances, entertainment centers or shelving units).
— Do not mount the Control closer than 2 inches to any
pipes, duct work, or other metal obstructions.
— Do not have metal obstructions, concrete or brick
walls between the Control and the router.
Refer to the 824 User Guide for additional information on
connecting the 824 to the Internet.
Wired Connections
The 824 Control may be connected to the Internet using its
built-in RJ-45 connector. When using a wired connection,
verify that a CAT 5 or better Ethernet cable with a male
RJ-45 connector is present from the router to the Control.
4.3 Mounting
Follow these steps to mount the 824 Control to the wall.
1. Turn OFF all power to heating and cooling equipment.
2. If an existing thermostat is being replaced:
a. Remove the existing thermostat from the wall.
b. Record color and terminal marking of each wire.
c. Disconnect the wires from the existing thermostat
being careful not to allow them to fall back into
the wall.
3. Carefully pry the Sub-base away from the 824 Control
using a small flat-blade screwdriver. Note that the
tight fit is normal and ensures that the Control is held
securely to the Sub-base when mounted on the wall.
4. Route the wires through the opening on the Sub-base.
5. If using a wired Internet connection, route the Ethernet
cable through the opening.
The onboard thermistor may be biased
by this heat causing the displayed
indoor temperature to be elevated.

6. Place the Sub-base against the wall in the desired
location and mark the wall through the mounting
holes. If you are using a wired Internet connection, be
sure to mark the cutout for the RJ-45 connector (see
Figure 2 on page 5).
7. Drill the holes in the wall where marked.
If you are using a wireless Internet connection, skip to
step 9.
8. When using a wired Ethernet connection, follow these
step and refer to Figure 3 on page 5.
a. With the Sub-base and RJ-45 holder oriented as
shown, press the holder into the Sub-base.
b. Slide the holder to the right so it snaps in place.
c. Secure the holder with the provided screw.
d. Insert the RJ-45 Connector into the RJ-45
holder until it snaps into place.
9. Mount the Sub-base to the wall using included
mounting screws and drywall anchors. An optional
mounting hole is available for more secure mounting,
if needed. Make sure all wires extend through the hole
in the Sub-base see Figure 4 on page 5.
4.4 Wiring
1. Adjust the length and position of each wire to reach
the proper terminal on the connector block of the
Sub-base. Strip 1/4” of insulation from each wire.
Do not allow adjacent wires to short together when
connected.
2. Match and connect control wires to the proper
terminals on the connector block. Refer to Field Wiring
Diagrams included in this document.
3. Push excess wire back into the wall and seal the
hole to prevent air leaks. NOTE: Air Leaks in the wall
