Afterwards the new safety value can be entered. Stop according to DIN EN 61010 When the cut-off temperature is reached, heating, cooling and pump are all turned off (Default setting). Cut-off mode: Process Safety When the cut-off temperature is reached the heating is turned off, but the cooling (at maximum power) and pump remain on. The full cooling capacity of the unit remains available for emergency cooling (possible exothermic reaction). Please ensure that the compressor automatic is switched to always on using the menu point Compressor automatic (F35). Please also see description on chapter Comfort menu for the respective Function numbers and their meanings. Display all OT values: The present measured temperature of the over-temperature sensors, the trip temperature set and the cut-off mode are displayed. Please note, that some units use two over-temperature sensors. When selecting Display all OT values both values will be displayed. 63
