Frost thermostat, 6 m, IP65, hysteresis +3K, STB, internal adjustment, external reset | RTKSA-203.220 Mounting brackets, immersion sleeves, and protective coils are not included in the scope of delivery and must be ordered separately. Air-side application: For frost protection of heating coils, the capillary is clamped in front of the heating coil to be protected using mounting clamps. For this purpose, the mounting clamps JZ-05 \/ 6 M (metal) or JZ-05 \/ 6 K (plastic) must be used.<\/p>\n – Safety temperature limiter (internal setting with reset) Operating voltage: none
\nThe RTKSA frost thermostats\u00a0are specially designed for air-side or water-side frost protection of boiler coils and heat exchangers in ventilation, heating, or air conditioning systems. The capillaries are active over their entire length. The device responds when the minimum response length of the capillary (30 cm) reaches the set scale value. In the event of a Sensor break, contact 1 \u2013 2 is permanently open and contact 1 \u2013 4 is permanently closed. Resetting is no longer possible.<\/span><\/p>\nNote<\/h3>\n
