Ranco ETC-212000-000 Two Stage Temperature Control with Sensor (24V Input) Temperature Controller

The Ranco ETC-212000-000 Two Stage Temperature Control with Sensor (24V Input) Temperature Controller is a Ranco temperature controller for HVAC repair and replacement work. Use it when the part number ETC-212000-000 and the listed specifications match the equipment being serviced.

Digital Display 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 1 degree 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 indicate when the relay is energized. Remote Temperature Sensing The ETC is capable of remote temperature sensing up to
