Charging

Selection of charging “Once/day“ or “Several times/day” is active only if DHW release is

 

set according to the time programs of the heating circuits.

 

Once / day

 

Release of DHW charging is given 2.5 hours before the first heat request fom the

 

heating circuit is received. Then, the reduced DHW setpoint applies for the whole day.

In the case of continuous heating (with no setback periods), release of DHW charging

 

is given at 0:00. The same rule also applies if the first request for heat from the heating

 

circuit is received before 02:30. If a request for heat is delivered at midnight, DHW

 

charging is released after the first setback period, but no earlier than 2.5 hours before

 

midnight.
