Engine Heater
This function is used to control the temperature of the engine. A sensor measuring the
cooling water temperature is used to activate an external heating system to keep the
engine at a minimum temperature.
The setpoints adjusted in parameter 6320–6324, 6330 are:
Parameter 6321 setpoint
This setpoint +/- the hysteresis is the start and stop points
for the engine heater.
The relay output for the engine heater.
Multi-input to be used for temperature measurement.
Hysteresis
This decides how big a deviation from the setpoint is
needed to activate/deactivate the engine heater
Enables the engine heater function.
