Minimum heating limitation (rigid):
The set minimum temperature value is maintained (value does not fall below
limit).
Advantage: Air draughts are largely avoided.
–
Disadvantage: The room can become slightly overheated, particularly if the
–
set values are too high, as the controller is not able to prevent overheating
using cooler air.
Minimum heating limitation (variable):
Value can fall below the set minimum temperature value if the current room tem-
perature value exceeds the setpoint by a value that is calculated as room tem-
perature difference multiplied by effective factor.
Advantage: Overheating of the room can be prevented or minimized by means
–
of the minimum limitation.
Disadvantage: The supply-air temperature can fall below the minimum limita-
–
tion temperature value.
