WATTS BMS-IMS Freeze Sensor Connection Kit

Installation Instructions

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 on new and existing installations to monitor temperature nearing the freezing point. With the BMS/IMS Freeze Sensor Connection Kit, the activated sensor relays a signal to a building or an irrigation management system, helping facility personnel take preventive action to reduce or eliminate equipment replacement and repair. Freeze alerts are distributed according to the BMS/IMS application.

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 or power issues.

Kit Components

The connection kit for installing and activating the freeze sensor includes the items shown below. If any item is missing, speak with your account representative about ordering code 88009429.

A. Freeze sensor with mounting clip

B. Activation module with vent and mounting hardware

C. Wire nuts

D. 5V DC power adapter

Requirements

2 Phillips screwdriver
Wire stripper
Tie, to hold the conductor cable to the valve
120VAC, 60Hz, GFI-protected electrical outlet (for kit power adapter), or 5V power source
Two (2) custom lengths of 2-conductor cable (sprinkler wire)
- 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 (The activation module is designed with two preset alerts. To receive both alerts, prepare an additional length of wire to connect each relay terminal to the BMS/IMS input, or use one4-conductor cable.)

How It Works

The activation module is designed with two relay switches, each with a fixed threshold. RLY1 temperature threshold is 37°F; RLY2 temperature threshold, 32°F.
Before either RLY1 and RLY2 is activated, decreasing temperature must drop below the fixed threshold for the preset time period. For RLY2 only, increasing temperature must rise above the fixed threshold for the preset time period before the relay is deactivated.
Either relay or both relays can be used according to user preference.

Set Up the Valve

The freeze sensor shown here is installed on a Watts 800M4 PVB. The installation steps are the same for any Watts valve that has a freeze sensor.

1. For retrofit installation only. Snap the mounting clip with freeze sensor over one of the 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 weather- proof wire nuts provided.
5. Use the tie to strap the first segment of the cable to the valve.

Connect Wiring to the Activation Module

Use a #2 Phillips screwdriver to remove the cover of activation module
Unscrew the 2-part vent and install the larger piece into the exterior side of the hole in the module housing, then attach the nut to the vent thread on the interior side.
Thread the sensor cable from the valve through the gland and insert one wire into the NTC+ terminal and the other wire into the NTC– terminal.
Thread the power adapter cable through the gland then connect the positive wire (black with white stripes) to the 5V IN spring terminal and the ground wire (all black) to the 0V IN spring terminal.
Use the wire stripper to cut ½” insulation off both ends of the conductor cable connecting the activation module to the building or irrigation management system. (If using both relay terminals, prepare two 2-conductor cables or one 4-conductor cable.)
Thread one end of the system cable through the gland to connect the RLY1 terminal for threshold 37°F or theRLY2 terminal for threshold 32°F. Open the levers of the selected terminal and connect one wire to the COM terminal and the other wire to either the NO (normally open) or the NC (normally closed) terminal, depending on the controller specification. Clamp the levers to secure the wires. (If using both relay terminals, repeat this step to connect the other terminal.)
Follow the manufacturer’s instructions to connect the other end of the cable to the building or irrigation management system.
Plug the power adapter into a 120VAC, 60Hz, GFI-protected electrical outlet.
