The Hydrolevel AcuTemp is an extremely versatile indirect water heater control. An LED display, push-to-set dial, adjustable settings for both residential and commercial temperature operating ranges, two different size (1/4- and 3/8-inch) 90-inch long sensors and remote mounting hardware, make the AcuTemp a suitable replacement control for virtually any indirect water heater (requires 24V power supply).
