The TempLogger is used to monitor and store marches of temperature in deep-freeze rooms. It corresponds to the "First Decree being an Amendment of the Decree on Deep-frozen Foodstuff". It is possible to monitor up to eight cooling rooms which are independent from each other. In units up to four channels a contact input can be assigned to each channel. If a signal is pending at these entries for more than 15 minutes, a message will be given. The entries are intended for monotoring cooling room doors.
