Zone temperature sensors

Zone temperature sensors are installed in each controlled area (zone) to measure the ambient room temperature and provide real-time feedback to the iZone system. The system uses this data to automatically adjust airflow to each zone, opening or closing dampers to maintain the set temperature for improved comfort and efficiency. Accurate placement of these sensors is important for optimal performance, ensuring they reflect true room conditions and are not influenced by drafts, direct sunlight or heat sources.

Wireless zone temperature sensors​

Wireless zone temperature sensors (CRFSW) sensors are battery-powered, RF-based temperature sensors that transmit zone temperature data directly to the CPU module (C225) without hardwired connections. Suitable for retrofit or inaccessible wiring locations, they require pairing to ensure reliable communication.

Wired zone temperature sensors​

Wired zone temperature sensors (CSW) sensors are hardwired temperature sensors that provide real-time zone temperature feedback to the CPU module (C225) via a direct cable connection. They are powered by the Wired Sensor Module (CWSM) and do not require batteries, ensuring stable communication and consistent data for zone control operation. Suitable for new installations, they offer reliable performance where wiring access is available. CSW

Zone wall controllers​

The iSense controller (CZCOW) is a wall-mounted temperature and user interface module that combines a zone sensor with local setpoint adjustment. It communicates with the CPU module (C225) or Network Extension Module (CNEM) to provide real-time temperature input and allows occupants to adjust zone temperature within predefined limits. The unit requires a wired connection (CAT5) for power and data, ensuring stable operation and consistent zone control feedback. ISENSE

System wall controllers​

Nexus+ controllers (CCTSLW+) and Nano controllers (CCTSSW) incorporate an internal temperature sensor within the wall-mounted touchscreen, providing local ambient temperature measurement without requiring an external sensor. The sensor feeds real-time temperature data directly to the CPU module (C225) for zone control algorithms and airflow modulation. This configuration reduces installation complexity but requires appropriate controller placement to ensure accurate readings. CCT
