    pool water sensor


    Heliotrope 4-wire Sensor Package
    The sensor package includes a 4-wire pool water sensor to measure the temperature of the pool water and a solar roof sensor to measure solar heat on roof. 

    Product Benefits:
    Maximizes pool water temperature

    pool water sensorPool Water Sensor
    This extra durable and virtually indestructible stainless steel sensor truly guarantees years of corrosion resistant performance. The sensor is wired into the system and signals the controller unit with readings on the pool water temperature.

    Product Applications:
    Measure temp. of the pool water
    Used in conjunction with the Heliotrope HelioMatic Solar Pool Control Unit - Model: HM
    Used as a replacement for the Heliotrope HelioMatic Solar Pool Control Package #1 - Model: HM-PKG
    Can be used with any Solar Control unit that requires 10K sensors


    Product Features:
    4 conductors (wires)
    2 thermistors potted in one plastic sensor well,
       with each of the two wires shrink-wrapped together.
    Stainless steel construction for extreme durability
    One year factory warranty


    The ISD-1.0-10K should be installed in the suction line from the pool between the pump and the filter. The dual thermistor format in the ISD-1.0-10K sensor satisfies two functions:

    1 - Water temperature for the solar differential and
    2 - Water temperature for the Display in the Controller

    Two wires from one thermistor going to the Pool Sensor position on the low voltage terminal strip and two wires going to the Display position on the low voltage terminal strip. This can be verified through ohm resistance.

    Note: Theoretically, the 2-wire IS-1.0-10k sensors can be used in conjunction with the display unit by incorporating two IS-1.0-10k sensors side-by-side. The IS-1.0-10k sensor for the display can be placed anywhere in the system (return from solar, ambient air, spa) to get a temperature reading at the controller display module.

    pool water sensorThe pool water sensor is attached to the PVC pipe; this requires drilling a hole in the PVC pipe, and using the stainless steel hose clamp (included) to secure the sensor in place.






Solar Roof Sensor


The AS-2-10 is an all-aluminum sensor block, designed to both quickly and precisely determine solar radiation [sun's rays], and then simulate the internal water temperature of the collector panels caused by the solar absorption. The sensor is placed in direct sunlight and mounted to the roof using a screw or adhesive.

heliotrope sensorThe sensor instantly signals the controller unit, which sends the required command to the 3-Way FloVerter Valve.

The greater surface area of the AS-2-10, combined with the superior conductivity characteristics of aluminum enable the sensor to detect the sun's rays sooner, plus detect when the right amount of solar energy is available.

It also reacts to cloudy conditions and the setting sun more rapidly than other sensors on the market today, thus creating greater heat flow precisely during the critical "solar window" period and avoiding heat loss by not circulating when heat could be lost through reverse process - resulting in a much warmer pool, and a longer more pleasurable swimming experience!

Product Applications:
Used to measure solar heat on roof
Used in conjunction with the Heliotrope HelioMatic Solar Pool
Control Unit - Model: HM Series
Used as a replacement for the Heliotrope HelioMatic Solar Pool
Control Package #1 - Model: HM-PKG
Can be used with any Solar Control unit that requires 10K sensors


Product Features:
All aluminum sensor block for superior conductivity
One year factory warranty

Heliotrope Solar Roof Sensor -  Installation Instructions:
Install black aluminum sensor where it will receive sunlight similar to the solar collectors. Use a cable clamp and TEK screw to mount [not included]. The cable clamp serves as a strain relief for the cable wires.

Install stainless steel drill-in sensor into 1-1/2” or 2” pipe to sense pool water temperature. Drill 5/16” diameter hole into pipe and install by using stainless steel clamp. Wires go through the hole punched into the clamp. This sensor goes into pipe ahead of the solar collector, usually near the pump.

Use 3M Scotchlok connectors [part number UY-2] for connecting the sensor leads to your interconnecting cable. Tie a knot with the cable wires and the sensor leads to function as a strain relief. Wire ends must not be stripped. Insert the insulated wire ends into the UY-2 and with pliers, press the round disc into place, locking the connection. Note that UY-2 is an improved connector over the UY because it makes a double contact with the wires and also accommodates larger wires.

Solar Sensor application troubleshooting tips:

Most well known brand controllers incorporate the use of 10k sensors. Some lesser known brands used 3k sensors. All GoldLine and Heliomatic controls use of 10k sensors.

To determine the type of sensor, the resistance must be measured
in ohms using a volt/ohm meter when the sensor is at 77 degrees F.

10k measures 10,000 ohms and 3k measures 3,000 ohms.
As the temperature goes up, the resistance goes down.

Resistance can be checked at any temperature, and then
convert the ohm reading measured to the temperature equivalent
by using the conversion chart.
