Frost protection thermostat TFR series

capillarydifferentialterminal block

Frost protection thermostat for downstream temperature monitoring of e.g. heat exchangers in ventilation and air-conditioning systems. The product offers a small differential gap and a high reproducibility. Resetting can be done automatically or manually (type '-R'). The frost protection thermostat can be used to perform the following functions: stop fan, close outside air dampers, open heating valve 100%, start heating pump, switch-off chiller (condenser) and de-/humidifier, trigger visual and/or audible frost alarm. • Application/type : Frost protection thermostat • Purpose : Measure values • Measured values : temperature • Interface : Switch contact • Functions : frost protection • Operating elements : rotary knob, -10..+15 °C, default setting +5 °C, reset button • Output switch contact : single pole change over, switching difference, 2 °C ±1 °C, switching capacity, 250 V ~, max. 10 A • Operating range humidity : max. 85% rH short term condensation • Accuracy temperature : repeatability ±0,5 K • Material in touch with media : Capillary pipe, copper with tube filling R507, sensor operating length approx. 600 mm, contact material Ag/Ni (90%/10%), gold plated (3 µm) • Installation length (mm) : 1800, 3000, 6000, 12000 • Enclosure : PA6 GK30 • Colour : light grey, transparent cover ABS • Protection (IP) : IP65, according to EN 60529 • Connection : cable entry M16 for wire Ø=8 mm, terminal block, max. 2,5 mm² • Delivery content : incl. installation set • Device length (mm) : 120 • Device width (mm) : 110 • Device height (mm) : 51 • Notes : mounting flange MF2 useable from installation length 3000 mm
