Active temperature monitoring.
The device has an active temperature
monitoring to protect it from damage
caused by excessively high interior
temperatures.In case of a temperature
increase above the predetermined
threshold value, the level control is
linearly reduced. To prevent a shut
down during reduced operation by to
high temperature of the entire system
(in this operating mode, allowable for
the controller) no switch off an no
alarm indication occurs by the relay.
