- Can be used with all 24VAC heating and cooling systems. It cannot be used with line voltage systems.
- Is Digital and your desired heat or cool temperatures can easily be set on the large screen with the TEMP UP (+) and TEMP DOWN (-) buttons on the front.
- A minimum 4-minute off time protects heating and cooling systems from damage.
- Uses a new technique called sequential staging for more comfort with faster reaction to requested temperature changes.
- Battery Backup with 2 x "AA" batteries (included)
The CA8900 is a digital thermostat that can be controlled wirelessly with Z-Wave controllers 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 CA8900 Wireless Thermostat provides two-way communication as part of a Z-Wave® network. When it receives commands from the Central Controller Unit, 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.
