Independent Heating/Ventilation

Operation
If an independent heating system is installed, the relay box, which switches the independent heating or independent ventilation program in the IHKA control unit, can be activated via the on-board computer. At the selected time, the on-board computer switches on the independent heating at an outside temperature < 16°C (61°F) and the independent ventilation at an outside temperature > 16°C (61°F). For test purposes, by switching the on-board computer in inverse mode, the function at < 16°C (61°F) outside temperature can be interchanged with the function at > 16°C (61°F) outside temperature.
