4.3. Location
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury
or death.
Disconnect power before routing control wiring.
!WARNING
All wiring must comply with national, local, and state codes.
4.3.1. Wall Control
The Infinity Touch Control is the command center for the Infinity System. It should
be located where it is easily accessible and visible to the adult homeowner or end
user. For accurate temperature measurement, the following guidelines should be
followed:
The Infinity Touch Control and Remote Room SensorsSHOULDbe mounted:
SApproximately 5 --ft (1.5 m) from the floor.
SClose to or in a frequently used room, preferably on an inside partitioning wall.
SOn a section of wall without pipes or ductwork.
The Infinity Touch Control and Remote Room SensorsSHOULD NOTbe
mounted:
SClose to a window, on an outside wall, or next to a door leading to the outside.
SExposed to direct light or heat from a lamp, sun, fireplace, or other
temperature --radiating objects which could cause a false reading. 
						

							6
SClose to or in direct airflow from supply registers.
SIn areas with poor air circulation, such as behind a door or in an alcove.
4.3.2. Remote Room Sensors
A Remote Room Sensor can be used with the Infinity Touch Control to take the
place of the control’s internal temperature sensor. This allows the Infinity Touch
Control to be mounted in areas with less than optimal airflow (such as near an
exterior door, window or in a closet). The remote sensor can be wired to the
terminal block connectors labeled S1 and S2 at the control’s backplate, or the ZS1
and ZS1C connection at the Damper Control Module. In either case, the Infinity
Touch Control will automatically detect the Remote Room Sensor and ignore its
internal temperature sensor.
4.3.2.1. Remote Room Sensor Averaging
Typically, one remote sensor is used but, multiple sensors may be used and
averaged in some applications. Averaging requires a special series --parallel wiring
method with a specific number of sensors. See figure below. It is also important to
note the humidity sensor cannot be remotely located, so do not locate the Infinity
Control in an area where humidity sensing may not be accurate.

4.3.3. Smart Sensors (for zoning applications)
Any zone may use a Smart Sensor. It provides a temperature display and buttons to
adjust the desired temperature in that zone only. It also displays outdoor
temperature and indoor humidity sensed at the control. Only one Smart Sensor may
be used per zone. They cannot be averaged like Remote Room Sensors. If a Smart
Sensor is used in a zone, a Remote Room Sensor may also be used in the same
zone. The Remote Room Sensor has priority over the Smart Sensor. The Smart
Sensor will display the Remote Room Sensor temperature.
NOTE: Smart Sensors must be addressed to identify which zone it will control. See
Smart Sensor Installation Instructions for details.
4.4. Wiring Considerations
Ordinary thermostat wire is recommended. Use 22 AWG or larger for normal
wiring applications. Continuous wire lengths over 100 ft. should use 20 AWG or
larger. 
						

							8
NOTE: ABCD bus wiring only requires a four--wire connection; however, it is
good practice to run thermostat cable having more than four wires in the event of a
damaged or broken wire during installation.
Each communicating device in the InfinityrZone System has a four--pin connector
labeled ABCD. It is recommended that the following color code be used when
wiring each device:
A — Green = Data A
B — Yellow = Data B
C — White = 24VAC (Com)
D — Red = 24VAC (Hot)
ABCD
A03193
It is not mandatory that the above color code be used, but each ABCD connector in
the system MUST be wired consistently.
NOTE: Some outdoor units provide their own low --voltage power source and do
not require the “C” (24VAC common) and “D” (24VAC power) connections. See
the outdoor unit installation instructions for more information.

ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing, modifying, or servicing system, the main
electrical disconnect switch must be in the OFF position. There
may be more than 1 disconnect switch. Lock out and tag
switch with a suitable warning label.
!WARNING
STurn off all power to equipment.
SIf an existing InfinityrControl or other control is being replaced:
dRemove existing control from wall.
dDisconnect wires from existing control.
dDiscard or recycle old control.
SNOTE: Mercury is a hazardous waste, if existing control contains any
mercury, itMUSTbe disposed of properly. The Infinity Touch Control
does not contain mercury.
SSelect Infinity Control mounting plastic (backplate and decorative backplate if
desired).
SRoute wires through large hole in mounting plastic. Level rear plastic against
wall (for aesthetic value only; Infinity Touch Control need not be level to
operate properly) and mark wall through two mounting holes.
SDrill two 3/16 --in (4.8 mm) mounting holes in wall where marked.
SSecure mounting plastic to wall using two screws and anchors provided. 
						

							10
SAdjust length and routing of each wire to reach each wire entry on the
connector backplate. Strip 1/4 --in (6.4 mm) of insulation from each wire.
SMatch and connect thermostat wires to proper terminals on control backplate.
dSee wiring diagrams in Appendix A.
SPush any excess wire into the wall. Seal hole in wall to prevent any air leaks.
Leaks can affect operation.
SAttach Infinity Control to the mounting plastic by lining up the plastic guides
on the back of the control with the opening on the mounting plastic and push
on.
SPerform installation of all other system equipment (i.e. dampers, humidifier,
ventilator, UV lights, etc.).
STurn on power to equipment.
4.4.1. Shielded Wire
If the thermostat wiring will be located near or in parallel with high voltage wiring,
radio, TV or Ethernet wiring, then four conductor, twisted --pair, shielded cable can
be used to reduce or eliminate potential interference. The shield wire should be
connected to the C terminal, or ground, at the indoor unit. The shield wire should
NOT be connected to any terminal at the user interface. Connecting the shield to
ground at both ends can cause current loops in the shield, reducing shield
effectiveness.
Connect one pair of the two --pair (minimum) cable to the A and B communication
terminals, and another pair to the C and D terminals at both ends of the cable. The
shield wire should ONLY be connected at the indoor equipment ground or C
terminal. Note that some outdoor units only require the A and B connections. See
the outdoor unit installation instructions for more information. 
						

							11
4.4.2. Damper Control Module (zoning systems only)
All wiring is run back to the Damper Control Module. Select a location near the
furnace or fan coil where wiring from the control, each Remote Room Sensor or
Smart Sensor, each damper actuator, and the equipment itself can come together
easily. The Damper Control Module is approved for indoor use only and should
never be installed with any of its components exposed to the elements. The Damper
Control Module (and zone dampers) may be installed in any area where the
temperature remains between --4_F to 158_F(--20_Cto70_C), and there is no
condensation. The cover must be installed to prevent damage from other sources.
Do not locate where it will be accessible to children. It may be mounted in either
vertical or horizontal position. Remember that wiring access is likely the most
important consideration.
PERSONAL INJURY HAZARD
Failure to follow this caution may result in personal injury.
To prevent possible damage to the Damper Control Module,
DO NOT mount on plenum, ductwork, or flush against
furnace or fan coil.
CAUTION!
4.5. Mounting
First become familiar with all plastic assembly pieces shown on the following page.
The Infinity Touch Control will snap together with the backplate. A backplate is
supplied. Attach backplate using only a small hole in the wall allowing a four wire
connection to pass through. Mount the assembly to the backplate.

A12215
NOTE: Once Infinity Control is secured to wall with the backplate assembly
(snapped together), care must be taken not to bend or break the interlocking tabs
when removing.
4.5.1. Decorative Backplate
Sold separately, a thin decorative backplate is available to hide any marks/screw
holes left from the previous thermostat. This decorative backplate (or beauty ring)
is used by snapping it onto the back of the mounting plate before securing the plate
to the wall.
