RANCO ETC COMMERCIAL TEMPERATURE CONTROLS:
The Ranco ETC is a microprocessor-based temperature controls designed to provide on/off control for commercial heating, cooling, With its wide temperature range, one and two stage capability, selectable heating/cooling modes and multi-voltage input, the ETC is one of the most versatile temperature controls available.
This Controller can power any Titanium Heater with or with out thermostat, you can hook up anything from 150 Watts to 1500 Watts, good enough to give you heat for up to 500 Gallon Aquariums, make sure you connect this unit alone on an outlet with 20 AMPS circuit braker.
Unlike many electronic controls, the ETC is simple to install and set up. One finger is all you need to program it. The standard digital display and keypad allow the user to adjust the temperature settings with 1Â° resolution. Setpoint temperature, differential and mode of operation (heating or cooling) can all be selected using the keypad and display.
When not in the programming mode, the display gives a constant readout of the sensor temperature. Annunciators on the liquid crystal display also indi- cate when the relay is energized.
Every ETC model is equipped with diagnostic programs that check for hard- ware, software or system problems and display different error codes to indicate where the trouble is.
The ETC also has a keypad lockout switch to prevent tampering with the control settings by unauthorized personnel. The switch, which is located inside the enclosure, can be used to disable the keypad function.
