The ETTR is a programmable temperature relay with the ability to act as an ON/OFF temperature controller. The device is capable of fully stand alone operation, but may be monitored and programmed with the custom software and a serial RS232 interface.
The Programmable Temperature Relay ETTR may be programmed in two control modes: (a) temperature range mode in which it will turn ON the output relay between two defined temperatures and (b) set point mode in which it will turn ON below a defined temperature and OFF above a defined temperature.
The span between the temperatures may be adjusted to customize the hysteresis. The Programmable Temperature Relay ETTR may also be placed in a manual mode of operation in which the relay is controlled via the GUI software.
