CA8900 Z-Wave Thermostat

The CA8900 is a digital thermostat that can be controlled wirelessly with Z-Wave controllers, like Vera, supporting the Thermostat General V2 Device Class. The thermostat is compatible with all standard 24 VAC heating and cooling systems, up to two-stage heat, one-stage cool, and two-stage heat pump. The CA8900 operates as a simple thermostat with buttons to set target temperatures for heat and cool modes. The Save Energy button adds two more modes for target temperatures to provide a single button set-back mode for easy operation. It can easily be retrofitted to existing systems as part of a Z-wave control strategy.

The WDTC-20 is a heating and cooling thermostat that offers extensive energy management solutions for your Z-Wave enabled smart home. It works with any contemporary 24 VAC HVAC unit. Offering support for all Z-Wave® controllers, it allows you to create "Home" and "Away" programs, "Heat" and "Cool" modes and adjust the temperature up or down all via Z-Wave OR manual operation. Also, the thermostat responds to basic ON and OFF commands sent by the controller by switching between between NORMAL (ON) mode and SAVE ENERGY (OFF) mode. This allows thermostat control with any Z-Wave remote, whether or not it has thermostat support.

The CA8900 Wireless Thermostat provides two-way communication as part of a Z-Wave® network. When it receives commands from the Central Controller Unit, such as Vera, it sends back confirmation that the command was received and implemented. Each module in a Z-Wave network communicates with every other module, acting as a “repeater” and routing your commands to their destination by the most reliable pathway. When Z-Wave devices (regardless of manufacturer) are installed throughout the house, signals are automatically routed around obstacles or dead spots, strengthening the network as more devices are added.
