Operation example: Schedule timer based on ON/OFF instruction.
When setback function is enabled, the setback operation will have
priority over the scheduled action in the schedule timer if ON
instruction is active. If OFF instruction is active this will have priority
over the setback function. At any time the OFF instruction will have
the highest priority.
Domestic water heating
Domestic water heating can be done through several standard
operation modes:
•
Automatic storage: by field setting, once during night and/or
once during the afternoon the water is heated till storage set
point.
•
Manual storage: if due to special circumstances, production
of hot water (till storage set point) is needed immediately
(1 time), this function can be used.
•
Reheat: the reheat function can be activated next to or
separate from the automatic storage operation if the user
wants to keep the domestic hot water tank at the minimum
reheat temperature.
Next to the standard domestic water heating operation modes, it is
also possible to freely program the domestic water heating operation
through the schedule timer (refer to "Programming quiet mode or
domestic water heating" on page 13). Then the mode is switched on
or off at a scheduled time. Five actions can be programmed per
mode. These actions are repeated daily (additional schedule of
storage on top of the automatic day and night storage functionality).
Quiet mode
Refer to "Programming quiet mode or domestic water heating" on
page 13.
Switch the mode on or off at a scheduled time. Five actions can be
programmed per mode. These actions are repeated daily.

NOTE
■
Remark that only the time when domestic water
heating must start and stop can be programmed
in the schedule timer. When domestic water
heating is enabled, the water will be heated till
storage set point. The storage set point is set
through field setting.
■
For energy-saving reasons, keep hours with low
electricity cost tariffs in mind when programming
the schedule timer for domestic water heating.
NOTE
■
If the auto restart function is disabled, the
schedule timer will not be activated when power
returns to the unit after a power supply failure.
Press the
pr
button to enable the schedule timer
again.
■
When power returns after a power supply failure,
the auto restart function reapplies the user
interface settings at the time of the power supply
failure (if time is shorter than 2 hours). It is
therefore recommended to leave the auto restart
function enabled.
■
The programmed schedule is time driven.
Therefore, it is essential to set the clock and the
day of the week correctly.
Refer to "Setting the clock" on page 4.
■
When the schedule timer is not enabled (
p
icon
not displayed), schedule timer actions will not be
executed!
■
The programmed actions are not stored according
to their timing but according to the time of
programming. This means that the action that was
programmed first gets action number 1, even
though it is executed after other programmed
action numbers.
