I have a system failure outside of office hours. What can I do?

I think the sensors are deviating, should I replace them with new ones?

In order to measure the temperature differences in the storage in time, you have to be sure that the sensors show no deviations. You should therefore check if they all give the same value. A simple way to test this is to place all product sensors in a bucket of water. After a few minutes, the temperatures should be equal. If the sensors then deviate, contact Tolsma-Grisnich: +31(0)527-636465.
