Description
RTKSA-204.200
Frost thermostat, 6m, IP40, hysteresis 1.5K, STW, internal setting | RTKSA-204.200
The RTKSA frost thermostats have been specially developed 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 – 2 remains permanently open and contact 1 – 4 permanently closed. Resetting is no longer possible.
Note
Mounting brackets, immersion sleeves, and protective coils are not included in the 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 clips. For this purpose, mounting clips JZ-05 / 6 M (metal) or JZ-05 / 6 K (plastic) must be used.
