iZone CDTS In-Duct Temperature Sensor
The iZone CDTS is an in-duct temperature sensor that monitors supply-air temperature within an iZone-controlled ducted air-conditioning system. It provides the C225 CPU with the temperature information required to correctly manage climate-controlled zone dampers during heating and cooling operation.
The CDTS is required whenever iZone zone-temperature sensors are used for climate control.
Key Features
Measures supply-air temperature inside the ductwork
Enables correct climate-zone damper operation in heating and cooling modes
Helps prevent unsuitable hot or cold air from entering temperature-controlled zones
Connects directly to the dedicated CDTS port on the C225 CPU
Supplied with an approximately 3-metre cable and RJ11 plug
Allows supply-air temperature to be viewed through compatible iZone interfaces
Recommended for diagnostic and system-support purposes
Application

Installation Information
Install the sensor:
In the main supply-air plenum
As close as practical to the indoor unit’s discharge
Upstream of all zone dampers
With the probe inserted fully into the airflow
Secure and seal the probe entry point with reinforced aluminium tape to prevent air leakage.
Connect the RJ11 cable to the dedicated CDTS port on the C225 CPU. Do not connect it to a zone-motor port.
