The 24-hour heating limit is used to switch the heating on and off in the course of the
day, depending on the outside temperature. This function is used primarily during
intermediate seasons (spring and autumn) to respond to short-time temperature
variations.
Example:
Setting line
Comfort setpoint (TRw)
24-hour heating limit (THG)
Changeover temperature (TRw-THG) heating off
Switching differential (fixed)
Changeover temperature
By changing the value entered, the respective heating periods will be shortened or
extended.
Increase: Heating mode will start earlier,
changeover to ECO later.
Decrease: Heating mode will start later,
changeover to ECO earlier.
· The function is not active in operating mode "Continuously Comfort temperature"
· The display shows ECO
· To give consideration to the building's thermal dynamics, the outside temperature will
be attenuated
Line no.

Using this limitation, a temperature range for the flow temperature setpoint can be
defined. If the flow temperature setpoint demanded by the heating circuit reaches the
relevant limit and the heat request increases or decreases, the flow temperature
setpoint will be maintained at the maximum or minimum limit.
