For my S60 MY2011 with diesel 163 HP machine I think about the retrofitting of a Webasto Thermo TOP Evo 5 heater with Thermocall. However, I came across various statements in the forum regarding the setting of the automatic climate control. As I understand it, the heater controls the blower motor for the interior after reaching a certain cooling water temperature. Temperature and valve position of the ventilation are not changed. Position Automatic air conditioning on AUTO and Temp. at 21°C after 30min heating time for an ice-free disc? It is only important to me that the windshield is ice-free.
