TURN OFF POWER TO HVAC SYSTEM
Locate the HVAC panel breaker and turn OFF the system. Before removing the old thermostat, initiate heating or cooling by changing the temperature setting. Ensure the HVAC system does not respond.
DETERMINE WIRING CONFIGURATION
If the BDXHTSL1 Smart Thermostat is being installed in a new system or if wiring changes are required, refer to Appendix A for the wiring configurations and skip to “Install Mounting Plate”.
When replacing a thermostat and replication of the existing wiring is desired on the BDXHTSL1 Thermostat, the following applies:

Remove old thermostat to expose the wiring terminals
Photograph the wiring for reference or,
Use the Wire Color Record to note the wire color and function of each wire. If the terminals of the existing thermostat are unmarked, determine the wire functions for each color wire at the appliance.

REMOVE OLD THERMOSTAT

Remove the old thermostat from the wall, taking care not to allow the wires to fall inside the void.

v_black+decker_smart_digital_thermostat_bdxhtsl1.png

WARNING: The BDXHTSL1 Thermostat IS NOT COMPATIBLE with supply voltages above 30 VAC. If the old thermostat is connected with thick wire and wire nuts or is labeled for voltages higher than 30 VAC, DO NOT INSTALL the Thermostat.

INSTALL MOUNTING PLATE (with WALL PLATE if required)

Note: Use 3/16” drill for wall anchors if no stud is present.

Use the included screws and wall anchors (if required) to attach the Mounting Plate to the wall, making sure the wires go through the center opening. Note the correct position indicated by the UP arrows molded into the plastic.
To cover paint or screw holes on the wall behind the thermostat, insert the Wall Plate between the Mounting Plate and the wall as shown. Both plates are secured with the same screws.

ATTACH WIRING
To insert a wire, loosen the screw corresponding to the labeled socket and slide the wire into the socket. Once the wire is inserted, tighten the screw snugly. DO NOT OVERTIGHTEN the screws. Pull gently on each wire after the screw is snug to make sure it is secure. Inspect the wires for oxidation and integrity.
