Space heating operation ( )
Space heating operation can be controlled in two different ways:
■
based on room temperature,
■
based on leaving water temperature.
The purpose of each operation and how the configuration 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.
Selecting space heating operation
1
Use the
button to switch ON/OFF space heating ( ).
Icon
appears on the display as well as the corresponding
actual room temperature.
The operation LED lights up.
2
Use the
and
buttons to set the desired room
temperature.
Temperature range for heating: 16°C~32°C (room temperature)
In order to avoid overheating, space heating is not operable
when the outdoor ambient temperature rises above a certain
temperature (see operation range).
Refer to
"4.12. Programming and consulting the schedule timer"
for setup of the schedule timer function.
3
Use the
and
buttons to select the leaving
water temperature which you want to be used to heat up your
system (for detailed information see
Automatic setback function
Setback function provides the possibility to lower the room
temperature. The setback function can for instance be activated
during the night because the temperature demands during night and
day are not the same.
The setback function is configured through field settings. Refer to the
chapter
"4.15. Field settings" on page 19
for a detailed description
how to set one or more field settings.
■
[2-00] Status: defines whether the setback function is turned ON
(1) or OFF (0)
■
[2-01] Start time: time at which setback is started
■
[2-02] Stop time: time at which setback is stopped
■
[5-03] Room setback temperature
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.
NOTE
■
Remark that the icon will be flashing during
setback operation.
■
By default the setback function is enabled.
■
The setback function can be combined with the
automatic weather dependent set point operation.
■
Setback function is an automatic daily scheduled
function.

NOTE
While room temperature setback function is active,
leaving water setback operation is also performed (see
"Leaving water temperature control" on page 6
Pay attention not to set the setback value too low,
especially during colder periods (e.g. winter time). It is
possible that the room temperature can not be reached (or
it will take a much longer time) because of the big
temperature difference.
