2. Safety Information
Please read all instructions carefully before installing or operating this thermostat. Failure to follow these instructions could result in property damage, injury, or death.
- Electrical Safety: Always turn off power to the HVAC system at the circuit breaker before installing or servicing the thermostat.
- Voltage Compatibility: This thermostat is designed for 24VAC systems only. It is NOT compatible with 120/240 VAC systems.
- Battery Installation: If powering the thermostat via 24VAC, do not install AA batteries. Batteries are for backup power only if 24VAC is not available or desired.
- Professional Installation: If you are unsure about any part of the installation process, consult a qualified HVAC technician.
3. Package Contents
Verify that all items are present in the package:
- 2GIG Z-Wave 700 Programmable Thermostat (Model 2GIG-STZ-1)
- 4 x AA Batteries
- Mounting Hardware (screws and wall anchors)
- Installation Manual (this document)
- Quick Start Guide
4. Installation
4.1. Preparing for Installation
- Turn off power to your heating and cooling system at the main circuit breaker.
- Remove your old thermostat's cover. Take a picture of the wiring connections for reference.
- Label each wire with the corresponding terminal letter from your old thermostat.
- Disconnect the wires and remove the old thermostat's mounting plate.
4.2. Mounting the Back Panel
The back panel of the 2GIG-STZ-1 thermostat serves as the mounting base and wiring terminal.
- Feed the wire cable from the wall through the access hole in the new mounting plate.
- Use the provided wall anchors and two Phillips screws to secure the back panel to the wall.
- Ensure the back panel is level for proper aesthetic alignment.
Figure 2: Illustration of mounting the back panel, showing wire access and screw locations.
4.3. Wiring the Thermostat
Connect the labeled wires to the corresponding terminals on the thermostat's back panel. Refer to your old thermostat's wiring diagram and the labels you made. The 2GIG-STZ-1 supports the following configurations:
- Standard Gas/Electric HVAC: Up to 2-stage heating, 2-stage cooling.
- Heat Pump HVAC: Up to 3-stage heating, 2-stage cooling.
- Humidifier/Dehumidifier Support: Dedicated terminals available.
For 24VAC power, ensure both "R" and "C" wires are connected. If a "C" wire is not available, the thermostat can be powered by 4 AA batteries, but it will not repeat Z-Wave signals in your network.
4.4. Attaching the Front Panel
Once wiring is complete, attach the thermostat's front panel to the mounted back panel.
- Align the front panel with the back panel.
- Gently press the front panel onto the back panel until it snaps securely into place around all edges.

After the front panel is attached, restore power to your HVAC system at the circuit breaker.
5. Operating Instructions
5.1. Powering the Thermostat
The thermostat can be powered by 24VAC from your HVAC system (if "R" and "C" wires are connected) or by four (4) AA batteries. If 24VAC is supplied, batteries are not required for operation but can serve as a backup. If only battery-powered, the thermostat will not function as a Z-Wave repeater.
5.2. Basic Controls
The thermostat features a clear LCD display and intuitive buttons for control:
- FAN Button: Cycles through fan modes (Auto, On).
- MODE Button: Cycles through system modes (Heat, Cool, Auto, Off, Em Heat).
- Up/Down Arrows: Adjusts the temperature setpoint.
5.3. Adjusting Temperature
Press the Up or Down arrow buttons to increase or decrease the desired temperature setpoint. The display will show the new setpoint temporarily.
5.4. Z-Wave Network Integration
To integrate the thermostat into your Z-Wave network, refer to your Z-Wave hub's instructions for adding new devices. The 2GIG-STZ-1 is a Z-Wave 700 series device, offering enhanced range and battery life. Once paired, you can control the thermostat remotely via your Z-Wave smart device or hub interface.
Note: For optimal Z-Wave performance and to function as a Z-Wave repeater, the thermostat should be powered by 24VAC.
6. Maintenance
6.1. Cleaning the Thermostat
To clean the thermostat, gently wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners, solvents, or spray cleaners directly onto the thermostat, as this may damage the unit or its electronic components.
6.2. Battery Replacement
If your thermostat is battery-powered, replace the four (4) AA batteries when the low battery indicator appears on the display. Ensure to use fresh, high-quality alkaline batteries. If the thermostat is 24VAC powered, battery replacement is not typically required for operation, but batteries can be installed for backup power.
- Carefully remove the front panel of the thermostat from the back panel.
- Remove the old AA batteries.
- Insert four new AA batteries, ensuring correct polarity (+/-).
- Reattach the front panel to the back panel until it snaps securely.
7. Troubleshooting
If you encounter issues with your 2GIG-STZ-1 thermostat, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat has no power/blank display. | No 24VAC power; dead batteries; incorrect wiring. | Check circuit breaker for HVAC system. Replace AA batteries if battery-powered. Verify "R" and "C" wire connections. |
| HVAC system not responding to thermostat. | Incorrect wiring; system mode set to "Off"; Z-Wave communication issue. | Double-check wiring. Ensure system mode is set to "Heat", "Cool", or "Auto". Re-pair with Z-Wave network if controlling remotely. |
| Temperature swing is too wide. | Thermostat differential settings. | Consult the advanced settings menu (if available) or your Z-Wave controller for options to adjust temperature differential. This setting controls how far the temperature deviates from the setpoint before the system activates. |
| Cannot connect to Z-Wave network. | Thermostat too far from hub; interference; incorrect pairing procedure. | Ensure thermostat is within range of the Z-Wave hub or a repeater. Follow Z-Wave hub's specific instructions for inclusion/exclusion. Ensure thermostat is 24VAC powered to act as a repeater. |
