Installation Instructions

Product Overview

Utilizes 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 can be 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.

Kit Components

• Freeze sensor in mounting clip: A small sensor unit attached to a black plastic clip, designed to be mounted onto a valve's test cock.
• Activation module: A white, rectangular electronic module featuring a Watts logo, connectivity status indicators (Power, Wi-Fi, Alert), and a multifunction button. It displays terminal connections and a QR code for setup.
• Standalone outdoor sensor: A white, cylindrical housing for an outdoor temperature sensor.
• DC 24 V power adapter: A black power supply unit with a standard plug and a DC output connector.
• Quick Start Guide: A folded document providing initial setup instructions.
• Wire nuts: Two blue connectors for securing electrical wire connections.

Requirements

• Small slotted screwdriver
• Wire stripper
• Two (2) custom lengths of 2-conductor cable (twisted pair preferred):
  • One length to connect the freeze sensor to the activation module.
  • The other length to connect the activation module to the building or irrigation management system.
• Tie, to secure the sensor cable to the valve.
• AC 120 V, 60 Hz, GFI-protected electrical outlet (for kit power adapter), or DC 24 V power source.
• For setting up notifications via the Smart Freeze Alert cloud service:
  • Wi-Fi connection.
  • Web browser.

Installation and Setup

Setting Up the Valve

The freeze sensor is shown installed on a FEBCO 765 PVB. The installation steps are the same for any Watts or FEBCO valve that has a freeze sensor.

1. For retrofit installation only. Snap the mounting clip with the freeze sensor over one of the valve's test cocks.
2. Remove the insulation from the freeze sensor leads.
3. Use the wire stripper to cut ½" insulation off both ends of the 2-conductor cable connecting the sensor to the activation module.
4. Connect the freeze sensor leads to one end of the cable using the provided weather-proof wire nuts.
5. Use the tie to strap the first segment of the cable to the valve.

Using the Standalone Outdoor Sensor

The standalone outdoor sensor can be installed instead of the valve-mounted sensor. For more information on installation, refer to tekmar Outdoor Sensor 070 at watts.com.

Wiring the Activation Module

The following steps apply to both the valve-mounted sensor and the standalone outdoor sensor.

1. Grasp the finger recesses on the top and bottom of the activation module and pull off the cover.
2. Connect the positive wire of the power adapter (black with white stripes) to terminal 1 and the ground wire to terminal 2.
3. Connect one wire of the sensor cable to terminal 3 and the other wire to terminal 4.
4. Use the wire stripper to cut ½" insulation off both ends of the system cable connecting the activation module to the building or irrigation management system.
5. Connect one wire of the system cable to COM terminal 6 and the other wire to either NO terminal 5 or NC terminal 7.
6. Follow the manufacturer's instructions to connect the other end of the cable to the building or irrigation management system.
7. Replace the module cover and plug the power adapter into a 120 V AC, 60 Hz, GFI-protected electrical outlet or connect it to a DC 24 V power source.
8. Mount the module in an unobstructed location for the best Wi-Fi signal.

Terminal Connections:

• 24 VDC INPUT: Connect the positive wire (black with white stripes) of the power adapter to terminal 1 and the ground wire to terminal 2.
• SENSOR INPUT: Connect one wire of the sensor cable to terminal 3 and the other wire to terminal 4.
• OUTPUT RELAY: Connect one wire of the third-party BMS or IMS input cable to COM terminal 6 and the other wire to either NO terminal 5 or NC terminal 7.

Setting Up the Alert System on a Wi-Fi Network

Hardware installation must be completed before product registration and Wi-Fi setup. Ensure that electrical power and Wi-Fi are available. The activation module does not need to be Wi-Fi enabled to work with a building or irrigation management system. Enable Wi-Fi to send email alerts independently of a third-party controller.

Initiating the Process

1. After plugging in the activation module, wait until the Wi-Fi blue LED starts to blink.
2. Use a mobile phone or computer to scan for new Wi-Fi networks, then:
   • Choose FreezeMonitorSetup-xxxxx. (The variable is a unique alphanumeric string for the device.)
   • Enter the password freezemonitor.
3. If the Watts webpage does not open automatically, launch a web browser and enter http://10.10.0.1, or scan the QR code.
4. Review the privacy policy by scrolling to the end, then tap Agree and Continue.
5. Review the terms of use by scrolling to the end, then tap Agree and Continue.
6. When the setup menu appears, tap Begin to complete the 4-step process.

Testing the Connection

Press the multifunction button on the module for at least 15 seconds to send the message. The Low Temperature alert serves as the test message.

How the Alert System Works

The freeze sensor measures temperature when energized by the freeze sensor activation module. The relay activates at 37°F (2.7°C) and remains active below 32°F (0°C).

The activation module can connect to a building management system, irrigation management system, or a Wi-Fi network. When connected to Wi-Fi, the system can be configured to send alerts via email and text message.

Press the multifunction button for the minimum number of seconds indicated to activate a function. Call customer service for technical assistance.

Messaging

Messaging is aligned with measured temperature. To silence messaging, press the multifunction button for 1 to 3 seconds. The Messaging ON function is restored by a change in condition (such as a temperature increase or decrease) or Wi-Fi status, as well as a reset or power cycle.

Temperature Alert Levels:

• Above Sensor Range: Sensor Error - Alert every 24 hours. Indicates the system is not measuring temperature correctly and requires attention.
• Normal Operating Temperature (Above 37°F): No alert issued. In normal operating mode, temperature is measured above 37°F.
• 37°F (2.7°C): Low Temperature Alert after 2 hours. Temperature is measured below 37°F. An alert is sent after 2 hours, with reminders every 12 hours. Normal operation resumes when temperature rises above 37°F.
• 32°F (0°C): Freezing Temperature Alert after 2 hours. Temperature is measured below 32°F. An alert is sent after 2 hours, with reminders every 12 hours. Low temperature alerts and reminders are issued accordingly when temperature rises above 32°F.
• Below Sensor Range: Sensor Error - Alert every 24 hours. Indicates the system is not measuring temperature correctly and requires attention.
