WATTS IS-FZ Freeze Sensor Connection Kit Installation Guide
WARNING
Read this Manual BEFORE using this equipment. Failure to read and follow all safety and use information can result in death, serious personal injury, property damage, or damage to the equipment. Keep this Manual for future reference.
You are required to consult the local building and plumbing codes prior to installation. If the information in this manual is not consistent with local building or plumbing codes, the local codes should be followed. Inquire with governing authorities for additional local requirements.
Freeze sensor solely provides alerts about a possible freeze event and cannot prevent a freeze event from occurring. User action is required to prevent freeze conditions from causing product and/or property damage.
Use smart and connected sensor technology with valve installations to monitor temperature and alert facility personnel when freeze conditions can cause damage to equipment. The Freeze Sensor Connection Kit includes two temperature sensors, allowing the user to choose which is more suitable for installation. One sensor can be mounted to a valve assembly; the other installed outdoors as a standalone unit.
When the kit is installed with either sensor, the sensor is activated and wired to a monitoring system. As temperature nears and reaches the freezing point, the monitoring system relays a signal to a connected building or irrigation management system, allowing freeze alerts to be distributed according to the BMS or IMS application. When the monitoring system is Wi-Fi enabled, notifications can be issued through the Smart Freeze Alert cloud service.
NOTICE
Use of the freeze sensor does not replace the need to comply with all required instructions, codes, and regulations related to installation, operation, and maintenance of this product, including the need to provide protection against a freeze event.
Watts is not responsible for the failure of alerts due to connectivity issues, power outages, or improper installation.
