14.2 Professional installator parameters
Release
When DHW heating is On, the release parameter (1620) can be used to determine when – within a 24-hour period –
DHW charging shall take place. When “
24h/day
” is used (the default value), DHW heating is continuously released as
long as it is On. The DHW setpoint is always the Nominal setpoint, unless the Legionella function has been activated.
When DHW heating is Off, the
Frost Protection
setpoint applies.
0 6 12 18 24 h
DHW heating can be released in 2 other ways:

Time programs HCs
When this setting is used, DHW heating is released during the occupancy times of the connected heating
circuits. If at least one of the heating circuits operates at the
Comfort
level, DHW heating is released also. If
all heating circuits operate at the
Reduced
level or in
Protection
mode, the DHW level is set to
Reduced
also.
To ensure that the DHW storage tank is already charged when space heating is started, the release of DHW
heating is brought forward 1 hour against the switch-on point for space heating.


Time program 4/DHW
When using this setting, a specific time program is available for DHW heating. For every weekday, a time
program with a maximum of 3 on phases can be set. During the release time, the Nominal DHW setpoint
applies, outside the release time, the Reduced DHW setpoint.

Charging priority
When both space heating and DHW heating call for heat, the DHW priority function (1630) ensures that while DHW
charging is in progress, the boiler’s capacity is used primarily for DHW heating.
Absolute
Mixing and pump heating circuits stay locked until DHW heating is completed.
Shifting
If the capacity of the heat source is not sufficient, the mixing and pump heating circuits will be restricted until the DHW
is heated up.
None
DHW heating and space heating take place at the same time. In the case of tightly sized boilers and mixing heating
circuits, the DHW setpoint may not be reached if space heating calls for considerable amounts of heat.
