7.15.7.3 Dynamic control of heating power
With insufficient flow rates at the heaters there is a risk that the heat transfer liquid is locally overheated.
This may lead to earlier aging, oil cracking at silicone oils (depolymerisation) or bubbling up. At small
pump levels the heating power is regulated automatically by the dynamic heating power control. Gener-
ally up from pump level 5 the maximum heater capacity is available at all devices.
This function can not be adjusted or disabled.
