Step 4: Wiring Information (continued)
IMporTanT! additional Wiring notes:
• For heat pumps with O and B both present, connect O wire to O terminal and B wire to C terminal (noTE:
This is typically for Trane Heat Pump products only.) Do not connect B wire to B terminal as it may
damage the 24VAC power system.
•
For LENNOX Pulse systems, please contact customer support or contact your HVAC professional for specific
information regarding installing the Z-Wave
®
Enabled Thermostat with your system.
• Use 18- to 22-gauge thermostat wire.
• Your Z-Wave® enabled thermostat must have a C wire (electrical power) and cannot operate from batteries
alone. Batteries are for back up only.
•
If you are unsure of how to connect your system, please call customer support for additional information or
contact an HVAC professional.
•
If you have 2 large wires (12 or 14 gauge or if it is bigger than paper clip wire) or know that your system
operates on line voltage, immediately stop, re-install your existing thermostat and contact customer support.
The Wayne-Dalton Z-Wave
®
Enabled thermostat operates on 24 Volts AC power only.
