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 IHKR2/3, can be activated via the on-board computer or multifunction clock. At a preselected time, the on-board computer (or multifunction clock) switches on the independent heating at an outside temperature <16°C (60°F) and the independent ventilation at an outside temperature > 16°C (60°F).
