SET POINTS
The following graphs describe how to program the hot water set points.
DHW set point normal/day time: (parameter P4 AA = 1/2)
D H W
s
6 0
This is the water temperature set point that is active during the
programmed DHW periods (parameter P4 AA = 1/2)
DHW set point reduction: (parameter P4 AA = 1/2)
D H W
R e d u c
1 0
The reduction of the normal/day time set point. This reduction is used
outside the programmed DHW periods.
Max. set point flow temperature (parameter P4 AA = 2 and
P5 DJ&DK =1)
H e a t
i
7 5
This parameter is the local setpoint of the water heater and is regulated
on sensor S1 (parameter P4 AA = 2, P5 DJ = 1 and P5 DK =1 ).

SETTING THE TIMER PROGRAMS
Two different programs can be set with the water heater, these are:
DHW program
Anti-Legionnaires' disease (pasteurisation) program
16.10.1 STARTING THE TIMER PROGRAMS
Three programmed periods each day can be set (period 1, 2 and 3). During this period the unit will use the normal DHW set point. Outside the
programmed period(s) the unit will use the reduced temperature as set point. When no time is programmed for a period, it will not be used.
(Example no time programmed in period 3 on Monday > "Mon 3 --:-- ---:--").

The
maximum
temperature will never exceed the
value set at heating setpoint
regardless of the DHW setpoint. If
the DHW setpoint needs to be
higher than the heating setpoint,
the heating setpoint will need to be
increased to match.
