USED SDI SEC III SOLAR DHW CONTROLLER FOR SALE AT $75

 

 

The Solar Development Inc. SEC III controller is designed to work as an air system controller for domestic hot water heating.

 

This controller uses two standard 10 K ohm thermistor sensors, one mounted on the collector and the second mounted near the bottom of the DHW tank wall.

 

The output relays are rated at 1 HP or 10 amps @120 VAC.

 

I've tested this controller and its delta Ts are 35 º/15º @ a storage temperature of 77 ºF, 32 º/13º @ a storage temperature of 126 ºF, and 32.5 º/14º @ a storage temperature of 156ºF. The high limit is set at 163.5 ºF.

 

If you are looking to replace your defective SDI SEC III DHW controller or just want one as a backup, order this one today as it is the only one left. Price shown does not include postage.  Colorado sales will be charged the appropriate sales tax. Yes, I accept credit card payments through PayPal, checks, and money orders.  For questions or to place an order, send me an email (see top of this page) stating what you are interested in along with your zip code.  I'll check the postage to your zip code and send you a return email with the total cost.
