operation.

Icon 

a

  appears on the display as well as the shift value. The

shift value is not shown in case it is 0.

bi

 and 

bj

 buttons to set the shift value.

Range for the shift value: –5°C to +5°C

Displaying actual temperatures

1

Push the 

ba

 button for 5 seconds.

The 

b

 icon and the outgoing water temperature are displayed.

The icons 

l

 and 

=

 are flashing.

2

Use the 

pi

 and 

pj

 buttons to display:

The outdoor temperature (

u

 icon is flashing).

The domestic hot water tank temperature (

w

  icon is

flashing).

The outgoing water temperature (

=

 are flashing).

If no button is pressed for 5 seconds, the controller leaves the
display mode.

Schedule timer operation

In schedule timer operation, the installation is controlled by the
schedule timer. The actions programmed in the schedule timer will be
executed automatically.

The schedule timer always follows the last command until a new
command is given. This means that the user can temporarily overrule
the last executed programmed command by manual operation (Refer
to 

"Manual operation" on page 5

). The schedule timer will regain

control over the installation as soon as the next programmed
command of the schedule timer occurs.

The schedule timer is enabled (

p

 icon displayed) or disabled (

p

 icon

not displayed), by pressing the 

pr

 button.

To set up the SCHEDULE TIMER refer to chapter 

"Programming and

consulting the schedule timer" on page 7

.

What can the schedule timer do?

The schedule timer allows the programming of:

1.

Space heating and space cooling (refer to 

"Programming space

cooling or space heating" on page 8

)

Switch on the desired mode at a scheduled time, in combination
with a set point (weather dependent or manually set). Five
actions per weekday can be programmed, totalling 35 actions.

2.

Quiet mode (refer to 

"Programming quiet mode, booster heating

or domestic water heating" on page 9

)

Switch the mode on or off at a scheduled time. Five actions can
be programmed per mode. These actions are repeated daily.

3.

Booster heating (refer to 

"Programming quiet mode, booster

heating or domestic water heating" on page 9

)

Allow or disallow booster heating at a scheduled time. Five
actions can be programmed per mode. These actions are
repeated daily.

4.

Domestic water heating (refer to 

"Programming quiet mode,

booster heating or domestic water heating" on page 9

)

Switch the mode on or off at a scheduled time. Five actions can
be programmed per mode. These actions are repeated daily.

NOTE

Remark that pushing the 

y

 button has no influence

on the domestic water heating. Domestic water
heating is only switched on or off by means of the 

v

button.

NOTE

Only use the 

pr

 button to enable or disable the

schedule timer. The schedule timer overrules the

y

  button. The 

y

  button only overrules the

schedule timer until the next programmed action.

If the auto restart function is disabled, the
schedule timer will not be activated when power
returns to the unit after a power supply failure.
Press the 

pr

 button to enable the schedule timer

again.

When power returns after a power supply failure,
the auto restart function reapplies the user
interface settings at the time of the power supply
failure.

It is therefore recommended to leave the auto
restart function enabled.

The programmed schedule is time driven. Therefore, it
is essential to set the clock and the day of the week
correctly. Refer to 

"Setting the clock" on page 4

.

Manually adjust the clock for summertime and
wintertime. Refer to 

"Setting the clock" on page 4

.

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. Refer
to 

"Setting the clock" on page 4

  to adjust the clock

and the day of the week.

The actions programmed in the schedule timer will not
be lost after a power failure so that reprogramming the
schedule timer is not required.

NOTE

When the unit is connected to an external room
thermostat, the schedule timer for space cooling and
space heating is overruled by the external room
thermostat.

The programmed actions are not stored according to
their timing but according to the time of programming.
This means that the action that was programmed first
gets action number 1, even though it is executed after
other programmed action numbers.

When the schedule timer switches space heating or
space cooling 

x

, the controller will also be

switched off. Note that this has no influence on
domestic water heating.
