Quick Start
Your system is controlled by a Wall-Mounted User interface
(WUI) that can be installed inside your home.
This manual provides guidelines on how to use this
interface eectively.
If you have any questions regarding the display and its
configuration, please contact your installer for more
information.
ŶHeating / Cooling: Depending on the unit, the system
may operate in Heating or Cooling.
ŶOccupancy control allows you to easily set the system to
operate in the following modes:
Home
Sleep
Away
ŶEasy temperature control: Depending on system
conguration, room temperature or water temperature
will be constantly displayed on the screen.
Room temperature icon indicates
that system control is based on room
temperature.
Water temperature icon means that the
system is controlled according to water
temperature.
ŶThe setpoint which is the temperature to be achieved is
displayed in the upper-right corner of the screen.
ŶSchedule control allows you to set the unit to operate
with a set of pre-dened parameters (heating/cooling,
occupancy, setpoint) in a specic period of time. You can
always modify the schedule if necessary.
ŶAdditional data display: In addition to the standard
display, you may easily check other parameters, which
provide information on the general status of the unit.
ŶAlarms are used to warn of potentially dangerous
situations that may result in the failure of the unit.
TIP To congure the advanced parameters of the unit, please
contact professional technicians.

A. Scheduling
The user can set up to 8 steps where each step is dened by
the following parameters:
ŶStarting time
ŶOccupancy mode
ŶDay(s) of week when it is activated
For more information about occupancy control based on
scheduling, please see “Scheduling: Assigning schedules to
heating and cooling modes”on page 12.
B. Manual setting
The user can change occupancy directly on the screen.
This setting will be eective until the next scheduling step
becomes active.
To set occupancy manually
1. Press the Occupancy key successively to select the
required occupancy mode.
2. The icon corresponding to the selected mode will be
displayed.
Home Sleep Away
The heat pump or chiller is running in the Home mode
and the Home setpoint is used.
The heat pump or chiller is running in the Sleep mode
and the Sleep setpoint is used.
The heat pump or chiller is running in the Away mode
and the Away setpoint is used.
Note To configure the setpoints of different occupancy
modes, refer to “ Current setpoint control: Changing
the temperature
To optimise energy eciency of the building while preserving
its occupants’ comfort, the controller is normally scheduled
according to occupancy hours.
If necessary, you can select the occupancy mode manually. Each
occupancy mode is associated with a pre-dened temperature
range.
Home / Sleep / Away: Changing the comfort range
To turn on the system
1. Press the Mode key to go from the OFF Mode to any
other mode.
To turn o the system
1. Press and hold the Mode key for 2 seconds.
2. The unit will be turned o, but the current time and day
will be still displayed on the screen.
WhentheunitisOFF,alloperating modesdescribedabove
(cooling / heating / DHW only / boost heating / boost
cooling) are disabled.
Never turn the power o to your system in order to ensure
that the home anti-freeze protection and the water
anti-freeze protection are always available.
Example:
Mode O

C. Occupancy lock
The current occupancy can be locked during a period
specied by the user (“occupancy lock”). During this time,
the scheduling will be ignored. Once this period has elapsed,
occupancy returns to the scheduling setting.
To set the time for the selected occupancy
1. Press and hold the Occupancy key for 2 seconds.
2. The length of Home / Sleep / Away period can be set in
hours or days. Press the Down key or the Up key to set
the required number of hours/days.
Example: Occupancy period (2 hours / 2 days)
Note Upon“23Hr”,the display switches todays (“1 d”).When
set in days, the dened occupancy will end at exactly
the same time it started. Afterwards, the mode dened
by the schedule will be in force.
3. To conrm the selected occupancy, press and hold the
Occupancy key for 2 seconds.
4. The lock icon will be displayed .
Example: Occupancy lock (Home)
To cancel the occupancy lock
1. Press and hold the Occupancy key for 2 seconds.
2. The display will show you the time remaining till the end
of the selected occupancy. Press the Down key to set the
counter to“0”.
3. To conrm your action, press and hold the Occupancy
key for 2 seconds.
4. The lock icon will disappear and the schedule will
be active again.

Current setpoint control: Changing the temperature
Two dierent congurations could be available:
ŶIf Parameter 510 “Control on Air” is set to NO, then the
setpoint control is based on the water temperature
ŶIf Parameter 510 “Control On Air” is set to YES, then the
setpoint control is based on the room (air) temperature.
Control type Current setpoint
Control on water Water setpoint
Control on air Air setpoint
To achieve better comfort, it is possible to adjust the current
setpoint according to your needs.
To adjust the setpoint
1. Press the Down key to decrease the temperature.
2. Press the Up key to increase the temperature.
Pleaserememberthatthesetpointcanbeadjustedonlywithin
a range dened for each occupancy mode.
Note 1 After a pre-defined period of inactivity (no key is
pressed), the setpoint information (air or water temp.
tobe achieved)is dimmed.By default, the timeout is 10
minutes.
Note 2 With the method described in this section, it is
also possible to congure the setpoint for dierent
occupancy modes, except when setpoint control is
congured on leaving water setpoint and with the
climatic curves (depending on installer conguration).
In this case, the setpoints cannot be changed by user.
If necessary, please contact a professional technician
to change the conguration.
WATER TEMPERATURE CONTROL
Example (water temp. and water setpoint):
Current setpoint 35°C
ROOM TEMPERATURE CONTROL
Example (room temp. and air setpoint):
Current setpoint 19°C

Scheduling: Assigning schedules to heating and cooling modes
The scheduling functionality makes it possible to set the unit to operate in a specic mode during a pre-dened period of time.
The system allows you to modify eight steps, where each step is dened by the day(s) of the week, start time, and occupancy.

Master / Slave control
Buildinginstallationsmayrequireafewunitstobeinterfaced
together in order to provide cooling / heating on the same
network.
The unit that is the decision point for the OPERATING MODE
and the CONTROL POINT is dened as the Master, all other
units belonging to the same group on the same network are
referred to as Slaves.
When the user interface is connected to the Master unit, the
Master / Slave icon is displayed on the screen.
If you change the operating mode or
dene a new setpoint on your “master”
user interface, this command will be sent
to all slaves on the network. The slaves
will act according to the command sent
from the Master.
When the user interface is connected to the Slave unit, the
Master / Slave icon is ashing rapidly.
If you change the operating mode or
dene a new setpoint on your “slave”user
interface, this command will be ignored.
The operating mode and setpoint dened
by the Master will be active.
When the Master / Slave communication failure occurs, the
Master / Slave icon is ashing slowly.
Inthecaseofmaster/slavecommunication

1. Daylight Saving Time (DST) usually starts/ends on Sunday morning (7). The clock goes one hour forward when entering DST (usually at 2:00 a.m.)
and one hour backward when leaving DST (usually at 3 a.m.).
2. This parameter denes the week number when the time change occurs:
#1: If “Day of Week” is set to 7 (Sunday), the time change will occur on the rst Sunday of the month.
#5: If “Day of Week” is set to 7 (Sunday), the time change will occur on the last Sunday of the month (it can be either 4th or 5th Sunday of the month).
