Boost heating (770, 1070, 1370)
TRw Room temperature setpoint
TRx Room temperature actual value
TRSA Room temperature setpoint-raised
The boost heating becomes active when the room temperature setpoint is
switched over from protection or reduced mode to comfort mode. During
the boost heating, the room temperature setpoint is increased by the value
set here. This causes the actual room temperature to rise to the new
temperature setpoint quickly.
Without room sensor or without room influence, boost heating is
implemented in accordance with an internal calculation. Due to the room
setpoint acting as a basis, the effect of the duration of the boost heating
and that of the flow temperature works differently for each outside
temperature.
Quick setback (780, 1080, 1380)
Quick reduction becomes active if the room temperature setpoint is
switched from comfort level to another operating level (reduced mode or
protection mode). During quick reduction the heating circuit pump is
switched off and the mixing valve is also closed in the case of mixed
circuits. During quick reduction no heat requirement is sent to the heat
generator.
Quick reduction is possible with or without room sensor: with room sensor
the heating circle function is switched off until the room temperature has
dropped to the reduced setpoint or frost protection setpoint. When the
room temperature has dropped to the reduced setpoint or the frost
protection setpoint, the heating circuit pump starts again and the mixing
valve is enabled. Without room sensor the quick reduction switches the
heater off depending on the outside temperature and the building time
constant (prog.no. 6110) until the temperature has theoretically dropped to
the reduced target value or the frost protection value.
