3. Contido do paquete
Verifica que todos os elementos estean presentes no paquete:
- 2GIG Z-Wave 700 Programmable Thermostat (Model 2GIG-STZ-1)
- 4 pilas AA
- Ferraxes de montaxe (parafusos e ancoraxes de parede)
- Manual de instalación (este documento)
- Guía de inicio rápido
4. Instalación
4.1. Preparación para a instalación
- Desconecte a alimentación do sistema de calefacción e refrixeración no disyuntor principal.
- Remove your old thermostat's cover. Take a picture of the wiring connections for reference.
- Etiqueta cada cable coa letra do terminal correspondente do teu termostato antigo.
- Desconecta os cables e retira a placa de montaxe do termostato antigo.
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. Cableado do termostato
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: Ata 2 stagCalefacción, 2 stage refrixeración.
- Heat Pump HVAC: Ata 3 stagCalefacción, 2 stage refrixeración.
- 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. Colocación do panel frontal
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. Instrucións de funcionamento
5.1. Acendido do termostato
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. Controis básicos
The thermostat features a clear LCD display and intuitive buttons for control:
- Botón FAN: Cambia ciclicamente polos modos de ventilador (Automático, Activado).
- Botón MODE: Cycles through system modes (Heat, Cool, Auto, Off, Em Heat).
- Frechas cara arriba/abaixo: Adjusts the temperature setpoint.
5.3. Axuste da temperatura
Preme o Up or Abaixo 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.
Nota: For optimal Z-Wave performance and to function as a Z-Wave repeater, the thermostat should be powered by 24VAC.
6. Mantemento
6.1. Limpeza do termostato
Para limpar o termostato, limpe suavemente o exterior cun pano suave eamp pano. Non empregue produtos de limpeza abrasivos, solventes nin produtos de limpeza en aerosol directamente sobre o termostato, xa que isto podería danar a unidade ou os seus compoñentes electrónicos.
6.2. Substitución da batería
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.
- Retire as pilas AA antigas.
- Insert four new AA batteries, ensuring correct polarity (+/-).
- Reattach the front panel to the back panel until it snaps securely.
7 Solución de problemas
If you encounter issues with your 2GIG-STZ-1 thermostat, refer to the following common problems and solutions:
| Problema | Causa posible | Solución |
|---|---|---|
| O termostato non ten alimentación/a pantalla está en branco. | 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. |
| O sistema de climatización non responde ao termostato. | 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. |
| Non se pode conectar á rede Z-Wave. | 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. |
