higher priority is present, then the "Window contact" message causes the controller to be set to
the setpoint value for frost/heat protection. In addition to manual setpoint adjustment and the
adjustment of the basic setpoint value, the setpoint temperature of the controller can also be
defined by objects "Superimposed operating mode", "Condensate water alarm", "Dew alarm",
"Window contact", "Control On/Off", "Presence detector" and "Operating mode (listed in
decreasing order of priority).
