Aqua Logic® digital temperature controllers can be used in a variety of applications where a device needs to be turned on / off based on temperature rise or fall. The Single Stage controller operates on one device, either a chiller (fan) or a heater.  The Dual Stage controller can be connected to both a chiller and heater, but only allows one device to be on at a time.

 A three-button touch keypad selects °F or °C, set point temperature, differential and operating mode (heating or cooling). A keypad lockout provides tamperproof protection and EEPROM memory retains control settings during power outages. The NEMA 4X enclosure is rated watertight for outdoor use. This temperature controller out performs others costing substantially more.

Temperature range for the controller is from -30 to 220°F (-22 to 105°C). The differential adjustment range is 1 to 30°F. Power cord lengths from the controller to the power supply and from the controller to the device being controlled are 40" (1 m) each. The temperature sensor probe is encapsulated in titanium making it completely waterproof for both fresh water and saltwater environments.
