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 - WiFi B-SAM is approved for indoor use only and should never be installed with any of its components exposed to outdoor environmental conditions. The WiFi 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 WiFi B-SAM can be located anywhere between the network router and HVAC equipment. WiFi B-SAM does not need to be located near the HVAC equipment and can be located near the router, where the wireless signal strength remains strong (good or very good).
!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 WiFi B-SAM (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.
Install Components
INSTALL WiFi B-SAM
The WiFi B-SAM is designed so that wires can be inserted through the back cover from 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 | 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 WiFi 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 WiFi 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
A separate 24VAC transformer is included to power the WiFi B-SAM. 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 boss on the transformer.
System Start-Up
The User Interface of the Evolution system will automatically find the WiFi 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 WiFi B-SAM (this ensures the module has power). The Green LED will be lit next to each ABC connection if the User Interface has established communications.
Network Setup
After the Evolution system has learned the WiFi B-SAM, the homeowner’s network parameters may be entered at the User Interface. If the homeowner’s network router is setup for DHCP, then the WiFi B-SAM’s network parameters cannot be changed. To edit the network parameters, enter the Advance Setup screens and press the right side button several times until WiFi B-SAM SETUP appears.
