14 ZS Combination Sensors
14.1 ZS Sensor Overview
The Bosch line of intelligent zone sensors provides the function and
fl
exibility you need to manage the conditions important to the comfort and
productivity of the zone occupants. The ZS sensors are available in a variety of zone sensing combinations to address most application needs.
These combinations include temperature, relative humidity, and indoor air quality (carbon dioxide). They are built to be
fl
exible, allowing for easy
customization of what the user/technician sees. Designed to work with the FHP560 controller, the ZS sensor line includes the ZS Standard, ZS
Plus, and ZS Pro.
