STT900
The frost protection thermostat STT is used for air, or water-side temperature
monitoring of heat exchangers, hot water circulation systems, water / air
heaters, e.g. in ventilation and air conditioning systems and for the prevention
of frost damage. The product features a small operating differential and high
reproducibility. Resetting of the STT900 to STT904 occurs automatically, and the
STT910-STT914 are designed to be reset manually by a reset button.
The output would typically switch off ventilators, close outside air flaps, open up
air heating valves, switch on air heat pumps, switch off refrigeration compressors,
switch off air humidifiers, or initiate a visual and / or acoustic frost alarm.
Location of these items in not critical, even in harsh environments as they are all
rated to IP65.
