SECTION I: GENERAL
The Touch Screen Communicating Control is designed to manage communicating system compo-
nents (including: heat pumps, air conditioners, air handlers and furnaces). In general, these compo-
nents are the variable speed modulating furnace, 2-stage variable speed ECM furnace and variable
speed air handler, premium 15 and 18 SEER air conditioners or premium 13, 15 and 18 SEER heat
pumps.
While the communicating system has been designed for easy installation, this document will pro-
vide the installer with a more detailed explanation of installation process.
SECTION II: SAFETY CONSIDERATIONS
This is a safety alert symbol. When you see this symbol on labels or in manuals, be alert to
the potential for personal injury and equipment damage.
Understand and pay particular attention to the signal words DANGER, WARNING, and CAUTION.
DANGER indicates an imminently hazardous situation, which, if not avoided, will result in death
or serious injury.
WARNING indicates a potentially hazardous situation, which, if not avoided, could result in death
or serious injury.
CAUTION indicates a potentially hazardous situation, which, if not avoided may result in minor or
moderate injury. It is also used to alert against unsafe practices and hazards involving only prop-
erty damage.
INSPECTION
The following list details the parts included in this kit. Examine the kit to insure that all parts are
included.
LIMITATIONS
The Touch Screen Communicating Control’s primary function is to command a system containing
communicating product.
Exceptions to this rule are:
• Installing a communicating variable speed modulating furnace with a non-communicating air
conditioner. In this case the variable speed modulating furnace relays 24 VAC outputs to the
non-communicating air conditioner (per communicated commands by the Touch Screen
Communicating Control).
• Installing communicating controls in non-communicating UPG products.
• Installing Communicating Interface Control (which converts communicating commands into
24VAC outputs).

MOUNTING THE TOUCH SCREEN COMMUNICATING CONTROL
For most installations, mounting Touch Screen Communicating Control can be done following some
very basic installation steps outlined below. However, there may be some cases where the installer
is not able to penetrate the wall where mounting the Touch Screen Communicating Control, or there
may be an application where the thermostat/control being replaced has left a larger hole than
needed for installation of this control. For these and other applications, (including installation with a
vertical j-box) an installer can obtain a Decorative/Mounting Kit (S1-02815909000).
1. If an existing thermostat or control is being replaced:
a. Remove existing control from wall.
b. Disconnect wires from existing control.
c. Properly discard or recycle old control.
2. Mark on the wall where the Touch Screen Communicating Control will be mounted (standard
height is 5 feet from the floor).
3. Cut a 2” x 2” square hole with the bottom of the square at the mark.
4. Using the mounting back plate as a template, mark the screw holes on the surface where
mounting the Touch Screen Communicating Control. Use a level to insure proper installation.
Voltage Hazard: Live wires can cause electrical shock or equipment damage. Disconnect power
before beginning installation.
Mercury is a hazardous substance, if existing thermostat or control contains any mercury, it
MUST be disposed of properly. The Touch Screen Communicating Control does not contain mer-
cury.
If an existing thermostat was in place, it may be ideal to use the same location for the Touch
Screen Communicating Control.
Make sure that the hole is cut so that the Touch Screen Communicating Control can be leveled
when mounted. See Figure 2 for more detailed mounting information.

5. Remove mounting back plate.
6. Drill holes (3/16” in diameter) in the marked area to accommodate the anchors (provided in the
kit).
7. Place anchors in the pre-drilled holes. Be sure that the anchors are fully inserted.
8. Pull low voltage wires through the mounting back plate as shown in Figure 3.
9. Connect low voltage wires as instructed in the wiring section of this document.
10.Screw the wired mounting back plate to the wall using the screws provided in the kit.
11. Align the terminal screw block with the pins on the back of the Touch Screen Communicating
Control and snap it to the mounting back plate.
REMOVING CONTROL MOUNTING BACK PLATE
Gently remove by tilting up to release the bottom of the Touch Screen Communicating Control and
then pull out/down to completely remove.

FIGURE 3: Wires Pulled Through Mounting Back Plate
Fastening the wires in the terminal block before attaching the back plate to the wall will ultimately
ease the installation of the wire. Once on the wall, the terminal block has limited accessibility.

SECTION IV: WIRING COMMUNICATION
All wiring must comply with local electrical codes and ordinances. Refer to Table 1 for terminal des-
ignations.
WIRING REQUIREMENTS
Standard 18 awg thermostat wires can be used to connect the communicating system.
Special (shielded) cable is not typically required. As with all communicating devices, it is a good
idea to keep wiring at least one foot away from large inductive loads. Examples of large inductive
loads include: electronic air cleaners, motors, etc. If these wiring practices are ignored, it may intro-
duce electrical interference (noise) which can cause erratic system operation.
SYSTEM WIRING OVERVIEW
The system is connected by four wires. Two of the wires are used to bring power into the individual
controls (R and C) and two of the wires are used for serial communication (A+ and B-). The plug/
harness that is provided in the kit should be used on the outdoor control.
Each Touch Screen Communicating Control Kit is equipped with a Communicating Plug Harness
(Fig. 5). This wire harness should be used for the wiring of the outdoor unit.

Terminal Designations
Signal Definition Label
Data Non-inverted signal A (+)
Low voltage power hot 24 VAC (Hot) R
Low voltage power common and data
ground 24 VAC (Common) C
Data Inverted signal B (-)
There may be installation applications where large inductive loads cannot be avoided. In these
cases shielded wire would be desired to ensure proper system functionality.
The communicating system requires 4 wires to operate. If installing a communicating system, be
sure to supply at least 4 wires to each unit/control. Below is a simple diagram showing the ideal
wiring path.

Jumpers listed here are required and if set incorrectly will flag an error upon installation. While the
other jumpers can be set from the Touch Screen Communicating Control, itis good practice to ini-
tially set all jumpers at the respective control. This will avoid any confusion that may occur with
future service at the units.
For installation of a non-communicating outdoor unit with the Touch Screen Communicating Con-
trol, the installer should reference the indoor and outdoor unit installation instructions. If informa-
tion is not provided, there may be a need for a Communicating Interface Control Field Kit (S1-
33102953000).
