Operation manual
10
Simultaneous demand of space heating and domestic
water heating
The unit can not perform domestic water heating and space heating
at the same time. If both modes are requested at the same time, the
unit will heat up till the reheat maximum temperature in 1 time. During
this period, space heating is not possible.
■
If you are using the remote controller room temperature control:
When the reheat temperature is reached, the further heat up of
the domestic hot water tank will be decided by the remote
controller room thermostat in order to prevent the room
temperature to drop too much.
■
If you are using the external room thermostat:
When the reheat temperature is reached, the further heat up of
the domestic hot water tank will be decided by the external room
thermostat thermo conditions and running timers which are
programmed by your installer.
■
If you are using the remote controller leaving water temperature
control:
When the reheat temperature is reached, the further heating up
of the domestic hot water tank will be decided by the running
timers which are programmed by your installer.

Space heating
Refer to
"Programming space heating" on page 13
.
Five actions per day of the week can be programmed, totalling 35
actions.
The space heating schedule timer can be programmed in 2 different
ways: based on the temperature set point (both leaving water
temperature and room temperature) and based on the ON/OFF
instruction.
The desired method is set through field setting. Refer to the chapter
"Field settings" on page 16
for a detailed description how to set one
or more field settings.
■
[0-03] Status: defines whether ON/OFF instruction can be used
in the schedule timer for space heating.
In the following tables both methods on how to interpret the schedule
timer are shown.

NOTE
By default space heating based on temperature set
point (method 1) is enabled, so only temperature shifts
are possible (no ON/OFF instruction).
Advantage of this method is that you can simply switch
off the space heating operation by pushing the
button without disabling the automatic domestic hot
water storage operation (e.g. during summertime when
no space heating is required).
