The controller offers the option of calculating service hours with a coefficient which is a function of the
main temperature measurement value.
Variable coefficient use can be selected via the
Variable Service Hours
parameter. If this parameter is
disabled, all service counters are calculated with a 1.00 multiplier independent of the main temperature
measurement.
When the variable coefficient calculation method is active (
Variable Service Hours
parameter is set to 1):
On load,
Up to
90 °C the multiplier is 1
Between 90-
95 °C the multiplier is 1.5
Between 95-
100 °C the multiplier is 2
Above
100 °C the multiplier is 3
Off load,
Up to 90
°C the multiplier is 0.5
Between 90-
95 °C the multiplier is 0.75
Between 95-100
°C the multiplier is 1
Above
100 °C the multiplier is 1.5

These coefficients are valid for all service counters.
