The RTKSA frost protection controllers have been specifically designed for air or water-side frost protection of hot water heating registers and heat exchangers in ventilation, heating, or air conditioning systems. In the event of a sensor failure, contact 1-2 will remain permanently open, and contact 1-4 will remain permanently closed. Unlocking is no longer possible. Note: Mounting brackets, immersion sleeves, and protective coils are not included in the delivery and must be ordered separately. For temperature measurement of non-aggressive gases in ducts, the protective coils SWK-2-xxx can be used. Water-side application: For temperature measurement in non-aggressive fluids, the immersion sleeves THK-2-xxx can be used, and for aggressive fluids, the immersion sleeves NTHK-2-xxx can be used.
