II.COMPONENT LOCATION AND WIRING CONSIDER- ATIONS

WARNING: ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury, death, or possible equipment damage. Disconnect supply power before routing wire.

NOTE: All wiring must comply with national, state, and local codes.

LOCATING SYSTEM ACCESS MODULE

—Since the System Access Module (SAM) uses two-way radio, choose a potential mounting location that is as high and as close to outside walls or windows as possible to attempt to maximize radio coverage. The coverage is dependent on where the Skytel trans- ceivers are located. If one location does not work, try the opposite side to get the device in closer directional proximity. Temporarily mount the System Access module in the intended permanent mounting location until the radio test has passed 100%.

The System Access Module is approved for indoor use only and should never be installed with any of its components exposed to the elements. The System Access Module may be installed in any area where the temperature remains between -4° and 158°F 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. The SAM should be mounted in the vertical position. Remember that wiring access and Skytel reception are the most important considerations.

Select a location near the Evolution furnace or fan coil where wiring from the User Interface, each Remote Room Sensor or Smart Sensor, each damper actuator, and the equipment itself can come together easily.

CAUTION: ELECTRICAL OPERATION HAZARD Failure to follow this caution may result in equipment damage or improper operation.

To prevent possible damage to the System Access Mod- ule, do not mount on plenum, duct work, or flush against furnace.

WIRING CONSIDERATIONS — Ordinary thermostat wire is ideal when wiring the System Access Module (shielded cable is not necessary). Use 22 AWG or larger for normal wiring. Lengths over 100 ft. should use 20 AWG or larger wire.

III. CONNECT POWER SOURCE AND ANTENNA

Screw the antenna to the radio connector. See Fig. 3 for antenna attachment location.

A separate 24 VAC transformer is included to power the System Access Module. DO NOT connect the D-wire (24 VAC hot) from the Evolution system.

The transformer is heavy. Make sure it is secured to the power outlet with an appropriate screw through the boss on the trans- former.

IV. RADIO TEST

The purpose of this test is to verify effective 2-way communica- tions at the installation site. The test must pass 100% before the installation of the SAM can continue.

Press and hold the RADIO TEST button for at least 5 seconds. A flashing Yellow LED will indicate the test is in progress. A flashing Yellow and Green LED means the transmission is complete and the System Access Module is waiting for a reply. A constant Green LED means the radio test has passed. The radio will perform three message tests, so this sequence will occur three times. If the System Access Module has errors during the process, the test could take up to 15 minutes.

—2—

If the Red LED is lit solid, then the System Access Module failed to send the message. Try a new mounting location for the System Access Module.

If the Yellow LED is lit solid, then the System Access Module sent its message but did not receive a reply. The Bryant server may be down or the received signal is weak. Try a new mounting location for the System Access Module.

Aborting Test - There is no method to abort a radio test once it is started, other than to remove power.

The LEDs will maintain their state for 1 hour after the test. Pressing the Radio Test button momentarily will clear the LEDs. Pressing the Radio Test button again for five seconds will repeat the radio test. See Fig. 2 for a description of the radio test and LED sequence.

V.INSTALL COMPONENTS

INSTALL SYSTEM ACCESS MODULE — Once the radio test has passed, the System Access Module can be permanently installed. The System Access Module 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.

VI. CONNECT EVOLUTION SYSTEMS

CAUTION: UNIT OPERATION HAZARD

Failure to follow this caution may result in improper unit operation.

Improper wiring of the ABC connector will cause the System Access Module to operate improperly. Check to make sure all wiring is correct before proceeding with installation or turning on power.

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 Data A

B — Yellow Data B

C — White 24VAC (Com)

NOTE: The D-wire (red - 24 VAC hot) from the Evolution system is not connected to the System Access Module.

It is not mandatory that the above color code be used, but each ABC connector in the system MUST be wired consistently.

VII. CONNECT AUXILIARY SENSOR (OPTIONAL)

The System Access Module 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 AUXC (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 shut down 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 home owner will also be notified via e-mail and/or phone if so chosen on the internet web interface.

VIII. SYSTEM START-UP

After a successful radio test has occurred, power may be applied to the Evolution System(s). The user interface of the Evolution System will automatically find the System Access Module at
