Aqua Logic® Temperature Controllers

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. Operation is simple. Just plug the device to be controlled into the controller's receptacle and plug the controller into a wall receptacle, then place the sensor probe in the water (or air).

The liquid crystal display (LCD) provides a constant readout of the sensed temperature. 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.

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 encased in titanium and has an 8' cable. Custom cables can be ordered up to 400' in length.

Single stage controllers operate one device, either a chiller (1/2 hp and smaller) or a heater (1,000 watts or smaller). Dual stage controllers can be connected to both a chiller (1/2 hp and smaller) and heater (500 watts and smaller). Amp draw of the item being controlled must not exceed amp capacity of the controller. Contactors may be used in conjunction with controllers to operate devices with higher loads.

Dual stage controllers will only allow one device to be "on" at a time. Example: stage 1 heating set point at 74°F with 1°F differential will have the heater come on when the temperature drops to below 73°F, then turn off at 74°F. Stage 2 cooling set point at 75°F with a 2°F differential will have the chiller come on when the temperature rises above 77°F, then turns off at 75°F. Total temperature variation is 4°F. A minimum of one-degree difference (dead band) must always be programmed between the heating and cooling set points. One-year warranty.
