ELEKTRA ETI thermostats are designed for DIN bus installation and temperature management in industrial systems such as: ETI 1544 – foundations of cold stores, production, workshop, and warehousing halls. ETI 1522 – Temperature regulation in thermally insulated pipelines covered by heating cables.
Any ETF series temperature sensor (floor or pipe installation) may be used with ELEKTRA ETI industrial electric heating controls. As On/Off controllers with adjustable hysteresis, they shut relay connections if the sensor temperature is less than the specified hysteresis value and the LED glows, and open contacts if the temperature is more than the set value and the LED does not illuminate. Terminals 4 and 5 must be linked to the cooling system. Elektra ETI controllers are equipped with switching relays and may thus be utilized as controllers for cooling systems. In this situation, connect the cooling system between terminals 3 and 5.
