For frost protection applications for pipes, OJ provides thermostat ETI along with temperature sensor for pipe ETF-6.
The ETI is an ON/OFF thermostat with adjustable differential temperature for control of temperature. When the sensor temperature is below the temperature set -1/2 differential the potential free relay is activated and heating is switched on.
When the sensor temperature exceeds the temperature set +1/2 differential the relay breaks and the heating element is switched out and the LED is turned off.
As the ETI is supplied with a change-over relay, the thermostat can also be used as a cooling thermostat.
