Page 16: Day Correction
The characteristic curve is used to control the heat dissipation of the heating circuit relative to the outdoor temperature. The demand for heat differs due to factors such as the type of building, heating, insulation and outdoor temperature. For this reason, the controller can operate with a normal straight curve (setting ‚simple‘) or split curve (setting ‚split‘). -

Page 18: Protective Functions
6. Protective Functions The 'Protective functions‘ can be used by specialists to activate and set vari- ous protective functions. By no means does the controller replace the safety appliances on site! Seizing Protection If the anti-seizing protection is activated, the controller switches the heat pump and the mixer on/off at 12:00 noon for 5 seconds to prevent seizing of the pump/valve after long periods of inactivity. -
