DCN: 140-02338-01 DRAFT 20619 Page 1 Installation Guide Model TBZ500 Battery Powered Z-Wave Thermostat This thermostat is compatible with most HVAC systems, including the following:  24VAC systems Note: requires both the R and C wires unless battery powered.  Standard gas/oil/electric heating systems o 1 stage heating and cooling o 2 stage heating and cooling  Heat Pump systems: o 1 stage heating and cooling o 2 stage heating and cooling o 2nd or 3rd stage Auxiliary heating (heat strips)  Do NOT use for line voltage controls (120/240VAC) The thermostat can be powered by batteries or 24VAC. Battery Power The thermostat can be powered by four AA Alkaline batteries. The thermostat will operate for approximately two years on four AA Alkaline batteries depending on the frequency of user operations and backlight operation. Always use Alkaline batteries and replace in complete all four at a time with new batteries. Z-Wave Operation when Battery Powered Important Note: If the thermostat is installed on a Z-Wave network, while it is battery powered, it will not work as a Z-Wave repeater. 24VAC Power Powering the thermostat with 24VAC power requires both the C wire (24VAC common wire - typically blue) and the R wire (24VAC hot wire - typically red). If the C wire is not available, then batteries are required. Note! If the thermostat is powered from 24VAC, batteries are not required. Z-Wave Operation when 24VAC powered If the thermostat is installed on a Z-Wave network while it is 24VAC powered, it operates as an always-on Z-Wave repeater. Installation Steps  Remove old thermostat.  Install TBZ500  Set up the thermostat for the HVAC system  Enroll on Z-Wave network Remove old thermostat  Turn off power. Usually at the heating/cooling system or circuit- breaker panel.  Remove cover of old thermostat to expose the wiring terminals  Take a picture of the wiring terminals! Note: This will help with troubleshooting later if needed.  Mark the wires attached to the terminals with the wiring labels included
