The thermostat has a single changeover contact, which can either switch on the heating if the temperature falls below the set point (heating mode), or switch on the fan/cooling if the temperature rises above the set point (cooling mode). Thanks to its high IP65 protection rating, it is ideal for garages, warehouses, workshops, greenhouses, stables, laundries and other technical and industrial premises. With a temperature range starting at -20 °C, it is also suitable for frost protection of buildings and equipment; the temperature setting is protected against unauthorised tampering by a plastic cover.
