RLE162

Compact electronic controller with immersion type temperature sensor and setting unit combined in one device. It is designed for installation directly onto the plant. Only the wires for power supply connection and controller output need to be laid. Threaded nipple (AQE2102) for direct temperature comes with the product RLE162.

Applications:
Modulating temperature controller, with 1 or 2 continuous DC 0…10 V output signals and auxiliary relay. The RLE162 is used for control and limiting of temperature in hot water, heating or cooling plants:

• Domestic hot water temperature
• Heating flow temperature
• Closed circuit heat exchangers
• Water-side control of HVAC units
• Chilled water temperature
