• Confirm with .After confirming, the
appliance enters "ONmode".
Note
If the preset temperature is higher than the current
water temperature, then the appliance might not
immediately start the heating cycle. To prevent
excessively frequent switching on and off, there is a
heating margin. The standard setting for this margin is
4°C. The appliance starts heating when the water
temperature is 4°C colder than the SETPOINT.
We refer to this margin as the hysteresis. The service
and maintenance engineer can adjust
(12.2 "Setting
the hysteresis") this setting.
11.4.2 Setting water temperature during
ON mode
The water temperature can also be directly adjusted
when the appliance is in the "ON mode". Simply use:
•
to increase the value;
• to decrease the value.
• Confirm with .
11.5 Week program
Using the week program, you can set the water
temperature for the days and times you want.
If the appliance is running under a week program, this
is indicated on the display by the
PROG
text on the first
line (see the figure). The second line shows the time
of day, the day of the week and the temperature. The
third line shows the next switching time of the week
program and the programmed temperature. The fourth
line shows the
PROGRAM ACTIVATED
text.
The appliance's default week program switches the
appliance on every day at 00:00 and off at 23:59. The
default water temperature setting is 65°C.
If you want, you can change every setting in the
appliance's standard week program.
If the water temperature becomes too low while the
week program is running, the appliance will run
through the heating cycle
(9.3 "The appliance's
heating cycle") and return to the week program.
This following are discussed:
•
Starting and stopping the week program
• Changing the appliance's standard week program
• Adding times to a week program
• Deleting times from a week program
11.6 Starting and stopping the week
program

11.7 Changing the appliance's standard
week program
Note
First fill-in the desired week program on the
supplied week program card.
A week program is made up of a number of
programmable periods in which you can have the
appliance switch on and off. A period consists of:
•
switch-on time: day of the week, hours and
minutes:
• switch-off time: hours and minutes;
• the water temperature setting;
• on/off setting for a program-controlled pump.
Note
The switch-off time must always be followed by a
switch-off time on the same day of the week. A
maximum of
three periods may be programmed per
day. You can program a maximum of 21 periods.
