ApplicationsTF…(R) is a device with the task of controlling the temperature of heating and cooling batteries, ventilation ducts and all those applications where frost damage can be prevented. The 15 (8) A switching contact (SPDT) allows use in a variety of functions such as controlling a fan, a shutter, an electric resistance, open or close a heating circuit or cooling circuit, start or stop a circuit pump ror heating or cooling, switch off a refrigerator unit or a humidifier, signal an alarm condition through a visual or acoustic device.FunctionThe thermostat TF switches when the temperature sensed by capillary for a minimum length of 50 cm drops below the temperature set on the knob. When temperature increases, the contact returns automatically to the initial position. For R versions it is necessary a manual reset from user to allow the contact to return to the initial position.The gas inside the sensible element increases his volume and with a mechanism acts on the microswitch. The capillary is sensible to temperature for the whole length. The models with range under the cover for setting the setpoint avoids any involuntary change of the set.AppearanceThe device consists of an ABS base and a transparent polycarbonate self-extinguishing cover, V0 class. The internal parts are made of technopolymer and stainless steel to guarantee its mechanical stability. The sensitive element is in copper filled with gas.
