INSTALL THE SENSORS

HEATING/STORAGE TANK SYSTEM SENSOR (HSS)

INSTALLATION

LOCATING HSS

• Put the Heating System sensor approximately 10' feet past the last boiler on the

common supply header but before any major takeoffs.

• The sensor must be located where it sees the output of all the boiler stages. If a

boiler is piped so that the sensor does not see its output, the TempTracker mod+

will not sequence the boilers correctly.

• Only use a Standard Brass Tube sensor.

• The sensor wires can be extended up to 500' using a shielded 2-conductor cable

(Belden #8760 or equivalent). Do not ground the shield at the sensor but at the

panel using one of the terminals marked with an “O”.

• Do not run sensor wires in conduit with line voltage wiring.

• Install a 3/8"ID 1/2"NPT immersion well.

• Insert the sensor probe of the supplied sensor into the well.

ALERT

If the System Sensor can not sense

the correct heating system water

temperature supplied to the building,

the TempTracker mod+ will not provide

comfortable heat levels. Be sure the

System Sensor is located on a main

supply pipe which can not

easily be

isolated from the system.

OUTDOOR SENSOR INSTALLATION

• Only use the Raypak sensor included with the unit.

• Locate the sensor in the shade on the north side of the building. The sensor

should never be in direct sunlight.

• Be sure the location is away from doors, windows, exhaust fans, vents, or other

possible heat sources.

• The sensor should be mounted approximately 10' feet above ground level.

• Adhere the Outdoor Label provided to the back of the sensor base.

• Use the Enclosure Base bottom knockout for the conduit. Use the locknut to

hold the conduit and enclosure base together. Screw the cover to the base.

• If screws are used to afx the enclosure to the wall, make sure to seal around the

sensor and wall except from the bottom.

• The sensor wires can be extended up to 500' using shielded 2-conductor cable

(#18/2). Do not ground the shield at the sensor but at the control using the

terminal marked with an “O”.

• Do not run sensor wires in conduit with line voltage wiring.

WARNING

The TempTracker mod+ is an operating control only. All boilers

must have all safety and limit controls required by code. It is the

responsibility of the installer to verify that all the safety and limits

are working properly before the TempTracker mod+ is installed.

ALERT

Determining the proper location for the Outdoor Sensor is very important. The TempTracker mod+ will base

the heat on the outdoor temperature information it receives from this location. If the sensor is in the sun, or

covered with ice, its reading will be different from the actual Outdoor temperature (OD).
