Space heating operation ( )
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 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 set point.
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 "Programming and consulting the schedule timer" on
page 12 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 "Leaving water temperature
control" on page 5).
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 "Field settings" on page 16 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
Leaving water temperature control
In this mode, heating will be activated as required by the water
temperature set point. The set point can be set manually, through the
schedule timer or weather dependent (automatic).
Selecting space heating operation
1 Use the button to switch ON/OFF space heating ( ).
Icon appears on the display as well as the corresponding
water temperature set point.
The operation LED lights up.
2 Use the and buttons to set the desired leaving
water temperature.
Temperature range for heating: 25°C~80°C (leaving water
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 "Remote controller schedule timer" for setup of the schedule
timer function.
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 5).
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.
NOTE
■ When an external room thermostat is installed,
the thermo ON/OFF is determined by the external
room thermostat. The remote controller is than
operated in the leaving control mode and is not
functioning as a room thermostat.
■ The remote controller ON/OFF status always has
priority over the external room thermostat!
