CAT- - 5 B- -SAM INSTALLATION
BEFORE STARTING:
S SYSTXBBUID01- -B or SYSTXBBUIZ01- -B is required
(version 14 software revision or higher).
Check Equipment and Job Site
INSPECT EQUIPMENT - - File claim with shipping company,
prior to installation, if shipment is damaged or incomplete.
Component Location and Wiring Considerations
WARNING
!
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 and
install a lockout tag. There may be more than 1 power
disconnect switch. Lock out and tag switch with a suitable
warning label.
NOTE: All wiring must comply with national, state, and local
codes.
LOCATING THE UNIT - - CAT- -5 B- -SAM is approved for
indoor use only and should never be installed with any of its
components exposed to outdoor environmental conditions. The
CAT- -5 B- -SAM may be installed in any area where the
temperature remains between - -4_F / - -20_C and 158_F / 70_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 should be mounted in the vertical position.
For wiring convenience, the CAT- -5 B- -SAM can be located
anywhere between the network router and HVAC equipment. The
CAT- -5 B- -SAM does not need to be located near the HVAC
equipment and can be located near the router, if a long Ethernet
cable run cannot be made.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage.
Do not mount unit on plenum, ductwork, or flush against
furnace.
WIRING CONSIDERATIONS - - Ordinary thermostat wire is ideal
when wiring the CAT- -5 B- -SAM into the HVAC system (shielded
cable is not necessary). Use 22 gauge or larger for normal wiring.
Lengths over 100 ft / 30 m should use 20 gauge or larger wire.
Network connections will require appropriate network wire - -
CAT- -5e shielded cable is recommended.
Install Components
INSTALL CAT- -5 B- -SAM
The CAT- -5 B- -SAM is designed so that wires can enter it from
behind, above, or below. Plan wire routing before mounting.
1. Remove cover to access mounting holes.
2. Mount back plate to wall using screws and wall anchors
provided.
3. Level back plate and tighten screws.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Improper wiring of the ABC connector will cause the system
to operate improperly. Check to make sure all wiring is
correct before proceeding with installation or turning on of
power.
Connect Evolution Systems
Connect the A, B, and C wires from the Evolution System to
terminals labeled A1, B1, and C1. Connect the second Evolution
System (if present) to the terminals labeled A2, B2 and C2.
ABC bus wiring only requires a three- -wire connection; however, it
is good practice to run thermostat cable greater than three wires in
the event of a damaged or broken wire during the installation.
It is recommended that the following color- -code be used when
wiring each ABC connector:
A - - Green
B - - Yellow
C - - White
NOTE: The D- -wire (red- - 24VAC hot) from the Evolution
System is not connected to the CAT- -5 B- -SAM. It is not
mandatory that the above color code be used, but each ABC
connector in the system MUST be wired consistently.
Connect Auxiliary Sensor (optional)
The CAT- -5 B- -SAM will support a dry contact sensor for use with
water detection or some other use as seen fit. Connect one side of
the contacts to connector AUX C (common) and the other side to
connector AUX (input). The sensor input can provide up to 20mA
at 5 volts d.c. If the sensor input is active, it will not shutdown or
affect operation of the HVAC system(s). A pop- -up message will
appear on the User Interface indicating the auxiliary sensor is
active. The homeowner will also be notified via email and/or
phone if so chosen on the Internet web interface.
Connect Power Source and Network Cable
Connect a network cable (RJ45 terminated). See Figure 1 for cable
attachment location.
A 24VAC transformer is required to power the CAT- -5 B- -SAM.
The transformer is available
(SYSTXNNXFM01). Do NOT connect the D- -wire (24VAC
hot) from the Evolution System.
The transformer is heavy. Make sure it is secured to the power
outlet with an appropriate screw through the base on the
transformer.
System Start- -Up
The User Interface of the Evolution System will automatically find
the CAT- -5 B- -SAM at power on. It will enter the system
installation screens automatically and will display the Equipment
Summary screen when finished. The Equipment Summary screen
will display REMOTE ACCESS near the bottom.
If REMOTE ACCESS is not displayed on the Equipment
Summary screen, check connections to the ABC wires as well as
ensure the yellow LED is lit on the CAT- -5 B- -SAM (this ensures
the module has power). The Green LED will be lit next to each
ABC connection if the
communications.
