Original Carrier Cor Release Notes


The Original Carrier Côr thermostat is a smart thermostat. The Côr has been tested and certified for integration with the ClareHome system.

Note: This integration only supports the Original Carrier Cor thermostat, not other thermostats in the Carrier Cor line.

By integrating the Original Carrier Côr thermostat to a ClareHome control system, your customers can send commands to the thermostat to change modes, cool and heat settings, and fan status from their mobile iOS devices or Android smartphones.

When integrating the Côr thermostat into your ClareHome project, no wires or extra connections are necessary. Install the Côr according to its documentation, and then connect it directly to Wi-Fi on the home network.

The Côr thermostat integrates with the ClareHome system in a way similar to the existing HVAC integrations. All HVAC integrations share a common UI, so that the user experience is consistent.

Temperature settings can be controlled via events. Use Fusion’s Scenes and Rules to automate the actions your customers want.

The Following figure shows the Côr controls on the ClareHome UI.
