    heliotrope sensor 
    Heliotrope 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.

    The 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 Benefits:
     Maximizes pool temperature 

     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

    Product Manufacturer: Heliotrope Pool

    Product 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.
