Thanks to its impact-resistant housing made of high-quality plastic, the 1-pole mechanical surface-mounted thermostat with relay output signal is very robust and can also be used under harsh conditions. The measuring system used can be used without problems up to a maximum permissible sensor temperature of 110 °C. The sensor cable of the thermostat is made of copper. The cable can be laid flexibly as required, provided a bending radius of 20 mm is observed. The maximum permissible ambient temperature on the housing is 55 °C. In order for the device to work correctly, the ambient temperature on the housing must be above the set switching point. The housing is attached directly to the lower part of the housing as a wall mount. The desired switch-off temperature is set using buttons and shown in two digits on a 7-segment display. The thermostat is characterized by a high switching point accuracy of +/-1 K. The device has a potential-free relay output that is designed as a changeover contact. The minimum switching capacity is AC/DC 12 V, 100 mA, the maximum switching capacity is AC 230 V, 6 (2) A or DC 24 V, 6 A. The device also has analog outputs which have a current of max. 1 mA at DC 0 to 10 V with a permissible cable length of 300 m at 1.5 mm. The analog input has a permissible current of max. 1 mA, DC 0 to 10 V. The power supply is AC 24 V. The frost monitor is very flexible and is used in building automation as well as in heating, air conditioning and ventilation technology.
