6.17.1 Overheat protection
The control unit offers thermal protection for the connected motors.
Two types of thermal-protection sensor can be connected to the
control unit: a PTC sensor (analog) and a thermal switch (digital).
Under normal running conditions, the sensor will act as a short
circuit, but when its temperature limit is reached, it will open and tell
the control unit that the temperature is too high, and the pump is
stopped. When the temperature has dropped to the sensor-trigger
level, the pump will return to normal running conditions. It will not be
possible to start the pump manually as long as the temperature is
too high.

6.17.2 Overload protection
The pump is protected by a motor-protection relay. The nominal
current draw must be set manually on the motor-protection relay.
See the specific documentation for the relay on how to set the
trigger level. If the current exceeds the trigger level, the relay will
switch off the pump and the controller will give an alarm. The alarm
has to be manually reset directly on the motor protection relay.

6.17.3 Moisture protection
When a moisture sensor is installed in series with the temperature
sensor, the control unit needs to know how to determine whether
there is a high temperature or moisture in the pump. If the
temperature is too high, normally the temperature sensor will go
back to its normal stage when the temperature has dropped to its
trigger level. If there is moisture in the pump, then the moisture
sensor will keep the series connection open until the pump is
opened and serviced.
To determine which sensor has been active, a cool down
time must be entered. This is the time that will normally pass until
the temperature has dropped enough for the temperature sensor to
return to its normal stage. If the cool down time is exceeded, the
control unit will assume that there is moisture in the pump, and it
will send a moisture alarm.
