The CT110 supports routing. This allows the device to communicate using other routing enabled devices as intermediate routers.  This device is unable to participate in the routing of data from other devices.

## Overview

The Z-Wave Plus enabled CT110 is a sleek, modern thermostat design for home automation systems. It’s clean user interface compliments app-enabled systems, and it connects to a Z-Wave network with one touch. The CT110 features adjustable real-time alerts to enable cloud triggers, a robust data stream of HVAC information for cloud monitoring, and configurable comfort response settings to customize home control scenes. The CT110 is compatible with all popular HVAC systems and is battery-operated without the need for a C-wire

### Inclusion Information

Press and hold the network button for 5 seconds.  The thermostat must be in OFF mode.

### Exclusion Information

## Association Groups

Association groups allow the device to send unsolicited reports to the controller, or other devices in the network. Using association groups can allow you to eliminate polling, providing instant feedback of a device state change without unnecessary network traffic.

The CT110 supports 1 association group.

### Group 1: Lifeline

The Lifeline association group reports device status to a hub and is not designed to control other devices directly. When using the Lineline group with a hub, in most cases, only the lifeline group will need to be configured and normally the hub will perform this automatically during the device initialisation.

Association group 1 supports 2 nodes.
