Solarcon is a solar controller repair business which specializes in the repair of Heliotrope General and Independent Energy products. 
Also available are several types of solar sensors, and the Flo-Verter solar pool valve. Heliotrope General, Inc. has closed their doors forever at the Spring Valley CA location after a tragic fire back on January 11, 2000.  As a former employee with over 17 years of FACTORY EXPERIENCE in repairing the multitude of often confusing variations of controllers, I am pleased to be the authority for repair of products manufactured by the former Heliotrope General, Inc. You will not find anyone with this much experience and knowledge of Heliotrope's products.

FREE Return Shipping on Repairs! Quick Service!

REPAIR IS ALWAYS THE MOST COST EFFECTIVE OPTION for your defective solar controller. For example, a new replacement for a DTT-94 will cost you $130.00 or more, whereas I repair that model for a flat rate fee of $60.00. A new replacement pool controller is especially expensive and runs over $200.00. I repair the HM-4000A, B, C, or D versions for only $65.00. Additionally, the electronics of the current DTT-94 and HM-4000D are now manufactured in a foreign country. Because Heliotrope used to manufacture so many models and product lines, repair is the only option in many situations. We can also repair most Independent Energy (Goldline) controllers including the C-30, C-100, and C-120.

Solarcon offers flat rate repair fees. These flat rates include all parts, labor, and return shipping. My average turnaround time is 2-3 working days. Any needed circuit upgrades that your controller may not have are installed as a part of the repair, at no extra cost. Instructions are also available for some products for a fee. Call or email for any instructions you are in need of.

A WORD ABOUT LEAKING SUNSPOOL/HG-SPOOL VALVES
The most common failure in the drain down valve is a continual leaking out of the drain tube while in the drain mode or position. This is caused by either the check ball inside port #4 failing, or a leaking O-ring. The most common cause by far is a failure of the check ball. Unfortunately there is no way to determine which of these is at fault without replacing the O-rings and/or check ball assembly. Solarcon sells O-ring kits and check ball kits on our "Flo-Verter & Drain Down" page. Please click on the page link above. We do not have parts for or repair the drain down valve electrical assembly.
