Technical Data
Unless limiting values are defined, the technical data
should be understood with tolerances of ±10% common
for heaters at an ambient temperature of +20°C, and at
nominal voltage.
Table 201 Technical Data
2.1
Electrical components
All components of the heater as well as the circulation
pump and the timer are available in two versions which
are designed for either 24 or 12 Volt nominal voltage. The
voltage for the temperature sensor is regulated by the
control unit.
NOTE:
Circulating pumps must be assigned to the heaters
according to the nominal voltage and flow resistance in
the coolant cycle.

1)
at rated conditions (rated voltage, winter Diesel, 15 °C)
2)
without circulating pump and heating element
3)
When permanently above 65°C, a reduced service life is assumed (a combustion air intake temperature of 65°C should not be exceeded)
4)
Minimum water flow at coolant temperatures above 50°C
Below 50°C a lower water flow is permitted, if the occurence of vapor bubbles due to local overheating safely can be excluded.
