■ 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.

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 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.

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.

Operation manual

Selecting space heating operation

1 Use the y button to switch ON/OFF space heating (h).

Icon h appears on the display as well as the corresponding water temperature set point.

The operation LED 0 lights up.

2 Use the bi and bj 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 11 for setup of the schedule timer function.

3 Use the ébi and ébj 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.

NOTE

■ Remark that the b 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.

The setback function is conﬁgured through ﬁeld settings. Refer to the chapter "Field settings" on page 14 for a detailed description how to set one or more ﬁeld settings.

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.

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 y button to switch ON/OFF space heating (h).

Icon h appears on the display as well as the corresponding water temperature set point.

The operation LED 0 lights up.

2 Use the ébi and ébj 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

Selecting weather dependent set point operation

When weather dependent operation is active, the leaving water temperature is determined automatically depending on the outdoor temperature: colder outdoor temperatures will result in warmer water and vice versa. The unit has a ﬂoating set point. Activating this operation will result in a lower power consumption than use with a manually ﬁxed leaving water set point.

During weather dependent operation, the user has the possibility to shift up or down the target water temperature by a maximum of 5°C. This shift value is the temperature difference between the temperature set point calculated by the controller and the real set point. E.g. a positive shift value means that the real temperature set point will be higher than the calculated set point.

It is advised to use the weather dependent set point because it adjusts the water temperature to the actual needs for space heating. It will prevent the unit from switching too much between thermo ON operation and thermo OFF operation when using the remote controller room thermostat or external room thermostat.

NOTE

1 Press the ba button 1 time to select weather dependent set

2 Use the ébi and ébj buttons to set the shift value.

3 Press the ba button to deactivate weather dependent set point

■ 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!

During this operation, instead of showing the water temperature set point, the controller shows the shift value which can be set by the user.
