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 88009430.
A. Freeze sensor with mounting clip
C. Wire nuts
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 one
4-conductor cable.)
RLY1 37°F Threshold
RLY2 32°F Threshold
Normal Operating Temperature
NO RELAY ACTIVATION
RELAY 1 ACTIVATED
RELAY 1 ACTIVATED
RELAY 2 ACTIVATED

B. Activation module with vent and mounting hardware
D. 5V DC power adapter
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 tem
perature 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.
When temperature drops below threshold,
alert delayed by 60 minutes
When temperature rises above threshold,
alert deactivated immediately
When temperature drops below threshold,
alert delayed by 30 minutes
When temperature rises above threshold,
alert deactivated after 30 minutes
