GC-TBZ48 BATTERY POWERED Z-WAVE THERMOSTAT INSTALLATION INSTRUCTIONS The Z-Wave Thermostat (GC-TBZ48) is a programmable, Z-Wave communica ng thermostat. It can be powered using 24VAC (if both “R”&”C”wires are available at the thermostat), or using four (4) AA ba eries. Using Z-Wave technology, end users have the ability to use the 2GIG Go!Control panel to control the thermostat, configure programming se ngs, as well as to display current condi ons in the home or office. Figure 1.

Thermostat Power The thermostat can be powered by either 24VAC from the HVAC system or from four (4) type AA internal ba eries. DO NOT use this thermostat for line voltage controls (120/240VAC). The C Wire If the 24VAC common wire (usually blue) is present and is connected to 24VAC common at the HVAC system end, the thermostat can be powered from the HVAC system and ba eries are not required. If there is no common wire, ba eries are required.
Remove Existing Thermostat • Turn off the power to the thermostat. This is usually done at the hea ng/cooling system or circuit breaker panel. • Remove the cover of old thermostat to expose the wiring terminals. • Take a picture of the wiring terminals and the wires before disconnecting them! • Mark the exis ng thermostat wires with the wiring labels included according to the terminal markings. Some installa ons may have addi onal wires not shown in this example illustra on. Y1, Y2, W1, W2, O,B.
Install the Back Panel Remove the back panel of the thermostat by pushing down the thumb tab on the bo om of the body. Figure 3. Removing back panel of thermostat. BACK PANEL BODY (WITH PCB) PUSH ON THUMB TAB TO RELEASE BACK PANEL Mount the thermostat back panel on the wall (See Figure 4). 1. Use the two (2) wall anchors and two (2) Phillips screws (provided) to mount the back panel. 2. Level as needed. Figure 4.
Standard HVAC System Connections NOTE: For typical connec ons to a Standard HVAC system, refer to the diagram on Page 2. The terminals on the back panel have two sets of labels. The upper label shows the STANDARD HVAC terminal connec ons. The lower label shows HEAT PUMP HVAC terminal connec ons. Figure 5.

Dual Transformer Systems For HVAC systems that have separate hea ng and cooling systems, each with their own 24VAC transformers, there will be an “R” wire from the hea ng system and an “R” wire from the cooling system. For dual transformer systems, connect the “C” wire from the cooling system to the thermostat’s “C” terminal. DO NOT CONNECT THE “C” WIRE FROM THE HEATING SYSTEM. Figure 7.
Heat Pump HVAC System Connections NOTE: For typical connec ons to a Heat Pump HVAC system, refer to the diagram on Page 3. The terminals on the back panel have two sets of labels. The lower label shows HEAT PUMP HVAC terminal connec ons. The upper label shows the STANDARD HVAC terminal connec ons. Figure 9.

Mount the Thermostat Install the thermostat body/front panel onto the wall mounted base by firmly pressing in place un l it snaps all around the edges. The GC-TBZ48 is now ready to program. Figure 11.
Thermostat Setup Menus The thermostat must be setup for the correct HVAC system type for proper opera on. Preset HVAC System seƫngs The thermostat is preset for the following typical HVAC system configura on: • HVAC system type: Standard gas/electric • HVAC fan type: Gas heat • HVAC hea ng stages: one • HVAC cooling stages: one If the thermostat is installed on this type HVAC system, the System Setup does not need to be changed.
Entering Menu Mode To change the System setup, go to the thermostats Menu Mode and select SYSTEM. From there select the correct HVAC se ngs to match the installa on type. Press and hold the FAN bu on to enter the Menu Mode. SETUP is the first menu item displayed. Press the bu on to advance to the SYSTEM screen. Figure 14.
System Menu The SYSTEM menu is used to setup the thermostat for the correct HVAC system type. The following setup op ons will be displayed in the text line: • HVAC System Type: Standard Gas/Electric or Heat Pump • Fan Type: Gas Hea ng or Electric Hea ng • Changeover Valve Type (for Heat Pump Systems): Changeover with Cooling or with Hea ng. To select op ons: • Use the bu ons to scroll to the desired se ng. • Press SELECT to change a se ng. The current se ng for that selec on will be flashing.
Z-Wave InstallaƟon Z-Wave controllers from various manufacturers may support the Z-Wave Thermostat General V2 Device class used by the Go Control Z-WAVE Thermostat. The following procedure will allow the thermostat to be added to a Z-Wave network. NOTE: Before adding the thermostat to a Z-Wave Network, check that it does not already belong to one by viewing the Node ID (ZNID) located in the Thermostat Info screen. An uninstalled thermostat should show zeros for the Node ID (000).
Clock Menu Use the clock menu to set thermostat’s internal clock. Figure 17.

Press any bu on to take thermostat out of sleep mode. Press FAN bu on for 5 seconds un l, SETUP appears in status display line. Use bu ons to select CLOCK in status display line.
Advanced System Seƫngs Menu The Advanced System Se ngs Menu provides for addi on system setup op ons. These se ngs can affect system opera on and should only be changed by qualified HVAC installers. To access the Advanced System Se ngs menu, first press and hold the FAN bu on to get into the Setup menu. While in the Setup Menu, press and hold both the FAN and bu ons for 5 seconds. • Use the bu ons to scroll through the menu op ons to the desired se ng. • Press SELECT (Mode) bu on to change a se ng.
Feature Description Range Default Setting Heat - Cool Delta Sets the minimum separa on between hea ng 3 to 15 and cooling setpoints. NOTE: Attempts to lower degrees cooling setpoint below the heating setpoint will PUSH the heating setpoint down to maintain this separation.
