This plugin allows Indigo to control Carrier Inc. Infinity heating and air conditioning (HVAC) systems. It allows you to read temperature and humidity sensors, change temperature settings, and all the usual conveniences. It also lets you observe events triggered from keypads.

The plugin requires a SYSTXCCSAM01 System Access Module (SAM), which you will need to have your HVAC contractor attach to your Infinity system bus. The SAM has a serial port which you can either connect to a USB-to-serial adapter on the computer running Indigo, or to a supported serial-to-network bridge such as a Global Caché IP2SL or similar.
