Space heating operation (
h
)
Space heating operation can be controlled on two different ways:
-
based on room temperature,
-
based on leaving water temperature.
The purpose of each operation and how the con
fi
guration is done, is
explained below.
Room temperature control
In this mode, heating will be activated as required by the room
temperature set point. The set point can be set manually or through
the schedule timer.
NOTE
Remark that pushing the
y
button has no
in
fl
uence on the domestic water heating.
Domestic water heating is only switched on or off
by means of the
w
button and/or disabling the
storage schedule timer.
NOTE
■
The clock needs to be set manually. Adjust the
setting when switching from summertime to
wintertime and vice versa.
■
If the controller is set to permission level 2 or 3
(refer to "Field settings" in the installation
manual), setting the clock will not be possible.
■
A power failure exceeding 1 hour will reset the
clock and the day of the week. The schedule timer
will continue operation, but with a disordered
clock. Therefor it will be needed to correct the
clock and the day of the week.
NOTE
When using room temperature control, space heating
operation based on room temperature will have priority
over leaving water control.
Note that it is possible that the leaving water
temperature becomes higher than the set point if the
unit is controlled by room temperature.
