FEATURES AND OPERATION OVERVIEW
OVERVIEW
The CC-STAT Vantage Communicating Thermostat provides the comfort and energy
efciency your customers expect with easy installation and full InFusion integration.
The CC-STAT may function as a stand-alone HVAC thermostat; however, the system
user will experience enhanced and simplied control when the CC-STAT is integrated
with the InFusion system. LCD interfaces and touchscreens provide the interface and
the CC-STAT, installed near the HVAC system, provides the control.
When combined with the Thermostat Interface Station, this multi-function thermostat
is compatible with most residential HVAC systems, including single stage, heat pump,
multi-stage and control of humidier and dehumidier systems.
• One thermostat for all applications - works with single-
stage, heat pump, multi-stage and control of humidier and
dehumidier systems
• On-board relative humidity sensor congurable to control
humidier and dehumidier
• Communicates with InFusion controller, Vantage
touchscreens, and mobile apps for remote operation and
feedback
• Direct connection of outdoor or indoor sensors
• Allows for temporary override of Vantage System without
altering initial programming
• Automatic set points controlled through the Vantage System
• Backward compatible

INSTALLATION OVERVIEW
INSTALLATION LOCATION RECOMMENDATIONS
THERMOSTAT MOUNTING
1. 120 volts may cause serious injury from electrical shock. Disconnect electrical power to the HVAC system before
starting installation. This system is a low-voltage system.
2. Improper installation may cause serious injury from electrical shock. HVAC systems must be installed by a
qualied contractor in accordance with NEC Standards and applicable local and state codes.
3. Installation of Vantage products should be performed or supervised by a Certied Vantage Installer.
4. DISCONNECT POWER TO ALL HVAC EQUIPMENT AND/OR ZONE CONTROL PANELS
• If the thermostats are wired to a zone control panel, there is generally one set of input terminals supplying power
to the thermostats and dampers. This must be disconnected.
• If the thermostats are wired directly to HVAC equipment, the power must be shut off at the equipment. This
can generally be accomplished by turning off the disconnect switch located near the equipment. If an obvious
disconnect switch is unavailable, you will need to turn the circuit off using the fuse or circuit breaker. Remove the
fuse or shut down the circuit breaker serving the equipment.
5. Failure to disconnect power could result in damage to the HVAC equipment or thermostats. Leave power
disconnected until all other electrical connections have been made and checked for accuracy.
WARNING - CAUTION!
THERMOSTATS SHOULD BE MOUNTED:
• On an interior wall, in a frequently occupied space
• Approximately 5 feet above oor
• At least 18” from outside wall
• Thermostat can be mounted to a vertical junction box.Direct
connection of outdoor or indoor sensors
• Allows for temporary override of Vantage System without
altering initial programming
• Automatic set points controlled through the Vantage System
• Backward compatible
DO NOT MOUNT THERMOSTAT:
• Behind doors, in corners or other dead air spaces
• In direct sunlight, near lighting xtures, or other appliances
that give off heat
• On an outside or unconditioned area wall
• In the ow of a supply register, in stairwells, or near outside
doors
• On a wall with concealed pipes or ductwork
1. Remove the rear mounting plate from the thermostat.
2. Pull wires through the opening in the rear mounting plate.
3. Position and level the mounting plate of the thermostat on wall
and mark the hole locations with a pencil.*
4. Drill 1/4” holes and insert supplied anchors (drywall only).
5. Place mounting plate over anchors, insert and tighten screws.
*The mounting plate may be anchored to a single gang box.
TIP: The CC-WLINT/RLINT will t through the hole in the rear mounting
plate.
6. Seal wire entry holes to prevent drafts affecting temperature readings.

CC-STAT OPTIONAL SUPPORT MODULES AND SENSORS
OUTDOOR TEMPERATURE SENSOR (OPTIONAL)
These support modules can be added when remote temperature or humidity sensor values are needed. Support modules can also be
used for sensor averaging in large areas (see Maximum Wiring Distances below). Support modules must be used in Control Mode,
see instructions shipped with module.
SUPPORT MODULES
Outdoor temperature can be measured by attaching Vantage’s SENSOR-ODT, outdoor sensor to the S1 and S2 terminals on the
thermostat base. The sensor must be enabled in the thermostat’s installer setup menu.
OUTDOOR SENSOR
(SENSOR-ODT)
These sensor can be directly wired to the CC-STAT thermostat, the CC-TEMPSUP, or to the CC-HUMIDSUP. See additional
instructions packaged with each sensor.
REMOTE SENSORS
Model CC-TEMPSUP Support Module
Provides two temperature values.
• 1 onboard or remote temperature sensor
• 1 remote temperature sensor
See additional instructions packaged with support module
In heat pump mode, the outdoor temperature sensor can
be used to efciently utilize an air source heat pump:
• When the outdoor temperature is less than the Low Balance
Point, the heat pump will be locked out and only auxiliary
heating will be used
• When the outdoor temperature is higher than the High
Balance Point, the auxiliary heating will be locked out and
only the heat pump will be used to provide heating
SENSOR-ODT FLUSHSENSOR SENSOR-SMT
Model CC-HUMIDSUP Support Module
Provides one temperature and one humidity value.
• 1 onboard humidity sensor
• 1 onboard or remote temperature sensor
See additional instructions packaged with support module
Outdoor temperature sensor should be mounted:
• On side of building out of direct sunlight (north side
recommended)
• Above snow line
• At least 3’ away from exhaust vents and condensing lines
• Using no more than 300’ of wire. (For longer runs, use the

THERMOSTAT TERMINAL WIRING DIAGRAM
WIRE SPECIFICATIONS
• 18-24 gauge thermostat wire
• CAT-5 or equivalent for communication terminals
• Vantage Station Bus – see page 9
INSTALLATION NOTES
• Ensure power at the thermostat location isoff.
• Loosen screw terminals, insert stripped wire and re-
tighten. See Wiring to CCWLINT CC-RLINT For HVAC
or Humidity Control in SECTION TWO.
• Push the excess wire back into the opening and plug
the wall opening to prevent drafts.
NOTE 1: If the Vantage thermostat is replacing an old
thermostat, check whether the old thermostat is powered
from an external 24VAC transformer or through the
RC or RH terminals. If thermostat power is provided
by an external 24VAC source do not jumper from the
R terminal to either the RC or the RH terminal. The
C* terminal should have connections from the HVAC
equipment, an external 24VAC transformer (if it exists)
and the CC-WLINT or the CC-RLINT interface station.
NOTE 2: Older systems may not have a C (common)
wire. If a common wire is not available from the HVAC
equipment please see the auxiliary switch solution from
Vantage, part number STAT-AUXS. This part adapts
existing 3 or 4 wire systems to 4 or 5 wire systems
requiring a common connection. Detailed instructions
are included with the STAT-AUXS.
1Refer to Vantage Integration later in this instruction and Vantage CC-WLINT / CCRLINT Installation instructions.
2O and B terminals are both de-energized when system mode is OFF or in AUTO when the heating and cooling equipment is idle.
