Smart, energy-efficient water temperature monitoring for commercial HVAC systems.
The ZS-IMM Communicating Immersion Sensor by Carrier is designed to deliver precise water temperature monitoring for commercial HVAC systems. Featuring a stainless steel probe with thermally conductive compound and double encapsulation, it ensures long-term reliability in diverse system conditions. Effortlessly integrated into Carrier's i-Vu controls, these immersion sensors simplify wiring and enhance building performance by connecting up to 15 sensors through a single controller port. The ZS-IMM empowers businesses with smarter climate monitoring, optimizing building comfort, energy efficiency and overall system uptime.
The sensor is designed for water temperature monitoring in chilled water, hot water, and boiler systems.
The design supports retrofit applications, allowing existing thermistor installations to be integrated into the Rnet network.
Streamlined wiring and reduced controller input requirements simplify overall system design and installation.
