DSC TBZ48D Product Description:


The DSC TBZ48D is a battery-powered Z-Wave wireless smart thermostat that is compatible with Z-Wave security control panels. The TBZ48D digital thermostat is designed to control the majority of HVAC systems. The TBZ48 contains a robust thermostat interface and is designed for use with communicating systems where remote monitoring and/or remote control are desired.

The TBZ48D can be operated by battery power or 24VAC. Please note, if the thermostat is installed on a Z-Wave network while it is battery powered, it will operate as Z-Wave FLiRS endpoint device. If it is installed on a Z-Wave network when it is 24 VAC powered, it operates as an always-on Z-Wave routing device.
