JOB NAME

Place

Between Pipe

And Sensing Element. Pipe Should Be
Clean And Smooth To Provide Proper
Thermal Contact With Sensing Element.

Thermal Mastic

Secure Sensor Element And Thermal
Mastic Strip To Pipe With Supplied
Wire Tie. Be Sure To Tighten Wire Tie
Snugly To Ensure Good Thermal Contact
Between Pipe And Sensing Element.

Butt Splice Or Wire Nut Wire Leads And Extend
Wire To Controller Terminals. Connect One Wire
Lead To Return Water Temperature Or Supply Water
Temperature Terminal At The Controller As Required
By Intended Use. Secure Other Wire Lead To
Ground Terminal At The Controller. See Note 3.

Notes:

1.)Sensor Should Be Mounted At

Location Along Pipe Length

That Best Represents Desired

Temperature Reading.

3.)All Wiring To Be In Accordance

With Local And National Electrical

Codes And Specifications.

2.)Sensing Element Shown

Mounted To Top Of Pipe. The

Sensor Element May Be Located

At Any Location Around Pipe.

Wire Tire
(Supplied)

Sensing Element
(Supplied)

Thermal Mastic Strip
(Supplied)

Supply Or Return
Water Pipe. See Note 1 & 2.

Important Note:

For Accurate Temperature Readings

It Is Necessary To Place Insulation Over

The Sensor After Installation. This Prevents

The Ambient Temperature From Affecting

The Sensor. Insulation Should Cover The

Sensor And Extend 6“ to 12” Beyond Each

End Of The Sensor.
