are initiated in "Automatic" mode and control the
change in temperature levels (and therefore the
associated setpoints, reduced and comfort) via the
adjusted changeover times.
Enter changeover times:
Changeover times can be adjusted in a combined
way, i.e., identical times for several days or distinct
times for certain days. Preselecting groups of days
(e.g., Mon...Fri and Sat...Sun) having the same

- (CS01 - 24) -
Control system / Single phase
Heating curve slope
Based on the heating characteristic, the controller
computes the flow temperature setpoint which will
be used for controlling the flow temperature in
consideration of atmospheric conditions. Different
settings can be used to adapt the heating
characteristic so that the heating capacity, and
therefore the room temperature, will match the
individual needs.
The colder the outdoor temperature, the greater the
extent to which the slope will modify the flow
temperature. In other words, the slope should be
corrected if the room temperature shows a
difference when the outdoor temperature is low, but
not when it is high.
-- Increase the setting:
The flow temperature is increased mainly when
the outdoor temperatures are low.
-- Decrease the setting:
The flow temperature is lowered mainly when the
outdoor temperatures are low.
Warning:
The heating curve is adjusted in relation to a room
temperature setpoint of 20°C. If the room
temperature setpoint is modified, the flow
temperature setpoint is automatically recomputed.
This will not modify the setting and amounts to
automatically adapting the curve.

Heating curve displacement
The curve displacement (offset) modifies the flow
temperature in a general and even manner over the
full range of outdoor temperature. In other words,
the displacement should be corrected when the
room temperature is generally too high or too low.
Heating curve adaption
Adaptation enables the controller to automatically
adapt the heating curve to the present conditions.

Control according to room temperature only
Simple control according to outdoor
conditions
The flow temperature is computed via the heating
curve according to the composite outdoor
temperature. This type of control requires proper
adjustment of the heating curve, as the control
does not take the room temperature into account
for this adjustment.
Control according to outdoor
conditions with room influence
The difference between the room temperature and
the setpoint value is measured and taken into
account for temperature control. This enables
taking into account possible heat inputs and
ensures a more accurate room temperature control.
The influence of the difference is defined as a
percentage. The better the installation in the
reference room (accurate room temperature,
correct installation location, etc.) the higher will be
the value that can be set.
Example:
Approx 60%: the reference room is appropriate
Approx 20%: the reference room is inappropriate
Information:
Activation of the function requires taking into
account the following requirements:
-- A room sensor must be connected.
-- The "room influence" parameter must be set

-- The reference room (where the room sensor is
installed) must not contain adjusted thermostatic
valves. If present in the room, these valves must
be fully open.
Control according to
room temperature only
The flow temperature is adjusted according to the
room temperature setpoint, the current room
temperature and its evolution. A slight increase in
room temperature, for example, causes an
immediate drop in the flow temperature.

Control according to outdoor conditions
with room influence
The difference between the room temperature and

account for temperature control. This enables
taking into account possible heat inputs and
ensures a more accurate room temperature control.
Thus the differences with the room temperature
are taken into account and the room temperature

difference is defined as a percentage.
The better the installation in the reference room
(accurate room temperature, correct installation
location, etc.) the higher will be the value that can

Control according to room temperature only
The flow temperature is adjusted according to the
room temperature setpoint, the current room
temperature and its evolution. A slight increase in
room temperature, for example, causes an
immediate drop in the flow temperature.
Activation of the function requires taking into
account the following requirements:
-- A room sensor must imperatively be connected.
-- The "room influence" parameter must be set to

If a value between 10 and 600 is selected, charging
will be suspended after the time period set in
minutes, and will remain suspended over that time
before resuming. The generator power remains
available in the meantime to heat the room. This
cycle is repeated until the DHW nominal setpoint
has been reached.
Information:
When the room heating is stopped (summer mode,
economy function, etc.), DHW charging remains
active, regardless of the setting.
Charging time limitation
During charging, the room heating (depending on
the charging priority defined on (line 1630) and on
the hydraulic circuit) may be stopped or insufficient.
Therefore it is often advisable to limit the charging
process timewise to enable heating.

mode
•• Substitute
The heater performs DHW charging as soon as the
heat pump is stopped or becomes inoperative, or if
the heat pump has finished charging without
reaching the setpoint.
The DHW tank heater switch-on point is calculated
so as to optimize the changeover level.
If the DHW temperature falls below the current
setpoint (line 1610 or 1612) minus the differential (line
5024) the heat pump will resume operation.
•• Summer
When all heating circuits change to summer mode,
the heater performs DHW charging starting on the
next day. The heat pump therefore stays off in
summer mode.
Production of DHW by the heat pump will resume
only if at least one heating circuit changes over to
heating mode. In that case, the heater operating
mode is the same as described in the "Substitute"
setting.
•• Always
DHW charging is always carried out by means of
the heater.
•• Cooling mode
When the heat pump operates in cooling mode, it
is possible to specify whether a DHW charging is to
be carried out via the heater, without cooling being
interrupted.
The DHW is prepared by the heater, if the heat
pump is in cooling mode or is not available (e.g. out
of order).
Information:
The DHW mode selection key also acts on the
heater. In order for DHW charging to take place,
the DHW key must be on.

•• Floor heating system
Heated floor thermal safety fuse.
-- The installer is responsible for connecting the
heated floor's safety system. Thermal safety will
stop the heat pump if the temperature in the floor
is too high. The heated floor's safety system must
cut the electrical supply of the heat pump with a
relay.
•• Contract with the power provider
The heat pump’s operation can be controlled to suit
special contracts (e.g. off-peak, day/night).
In particular, domestic hot water (DHW) at Nominal
temperature will be produced during the off-peak
hours when electricity is cheaper.
-- Connect the "Power Provider” contact to input
EX5.
-- Set the parameter line 1620 to “Off-peak hours”.
-- 230V on input EX5 = “Peak hours” information
activated.
(Basic setting / Modification possible line 5989,
menu Configuration)
•• Power limitation or EJP
(peak day removal)
Power limitation is intended to reduce electrical
consumption when this is too high compared to the
contract with the power provider.
-- Connect the power limiting device to input EX4,
the back-ups for the heat pump and the DHW
stop in the event of over-consumption by the
dwelling.
-- 230 V on input EX4 = power limitation in
progress. (Basic setting / Modification possible

Connections to regulator (accessories and options)
The outdoor sensor is required for the heat pump to operate correctly.
Consult the fitting instructions on the sensor packaging.
Place the sensor on the coldest part, generally the northern or north-eastern side.
In any case, it must not be exposed to the morning sun.
It must be installed so as to be easily accessible but at least 2,5 m from the floor.
It is essential that it avoid any sources of heat such as flues, the upper parts of doors and windows,
proximity to extraction vents, the underneath of balconies and under-eave areas which would isolate the
sensor from variations in the outdoor air temperature.
-- Connect the outdoor sensor to the M and B9 terminals on the heat pump control board.
ROOM THERMOSTAT AND / OR REMOTE CONTROL
„„
The room thermostat (remote control) is optional.
Consult the fitting instructions on the sensor packaging.
The sensor must be installed in the living room area on a very uncluttered wall, 1,5 m above the floor.
Avoid direct sources of heat (chimney/flue, television, cooking hobs), draughty areas (ventilation, door, etc.).
Air leaks in the seals in the constructions are often translated into cold air blowing through the electrical
conduits. Lag the electrical conduits if there is a cold draught on the back of the IR sensor.
-- Installation equipped with the room thermostats:
-- Connect the sensor to one of the CL+ or CL- terminal.
-- Installation equipped with a room thermostat and a remote control:
-- Connect the remote control: terminal CL+ on (1), CL- on (2) and G+ on (3).
DHW SENSOR
„„
If the installation is equipped with a DHW tank (with electric back-up):
-- Place the domestic hot water sensor in the housing for the cylinder sensors.
-- Connect the domestic hot water sensor to terminal BX1 and M.

START-UP
„„
-- Ensure that the start-up switch of the control box is set to 0.
-- Close the installation’s main circuit breaker.
On first commissioning (or in winter), in order to allow the compressor to pre-heat, engage the
installation’s main circuit breaker (power supply to the monobloc unit) some hours before starting up
the tests.
-- Switch-on the start-up switch of the control box (position 1).
To ensure that inputs EX4, EX5 and EX6 operate correctly : Check that the live-neutral polarity of the
electrical supply is correct.
When the power is switched on and every time that the ON/OFF button is switched off and then
switched on again, the monobloc unit will take approximately 4 minutes to start up, even if the setting
is requesting heating.
During the regulator initialisation phase, the display shows all the symbols and then "Data update" and then
"State heat pump".
-- Make all the specific adjustments to the setting (configuring the installation).
-- Press the key
OK
-- Hold down the key
-- Confirm with the key
for 3s and select the level of access used with the aid of the knob
.
OK
Parameter the heat pump’s setting (See “ FUNCTION TABLE of 2-3 CONTROL SETTING”.).
In case of error 10 (Outdoor sensor), the regulating system uses an average initial outdoor temperature of
0°C and requires some time to update this temperature.
To avoid this situation, the sensor must be connected correctly.
Re-initialise line 8703 (commissioning level, consumer diagnostic menu).
Configure the room thermostat and connect it to the appropriate heating zone:
-- Hold down the occupancy key for more than 3 seconds. The room thermostat displays RU and a number
flashes.
-- Turn the wheel to choose the zone (1).
-- Press the occupancy key; the room thermostat displays P1 and a flashing number.
1: Automatic recording : a correction of the setting with the button is adopted without any particular
confirmation (timeout) or by pressing the regime key.
2: Recording with confirmation: a correction of the setting with the button is not adopted until the regime
key is pressed.
-- Press the occupancy key again; the room thermostat displays P2 and a flashing number.
0: OFF : all the operating elements are engaged.
1: ON : the following operating elements are locked:
Switching over the heating circuit’s operating mode
Adjusting the comfort setpoint
Changing the operating level (Heating mode key)
The room thermostat displays OFF for 3 seconds when a locked button is pressed.
CONFIGURING THE REMOTE CONTROL
„„
During commissioning, after an initialisation period of approx. 3 minutes, the user’s language must be set:
OK
-- Press the key
-- Choose menu "Operator section".
-- Choose "Language".
