2.2 Instructions for safe operation
NOTICE
Room frost protection. Even if you turn OFF space
heating/cooling operation ([C.2]: Operation > Space
heating/cooling), room frost protection –if enabled– will
remain active.
NOTICE
Water pipe freeze prevention. Even if you turn OFF
space heating/cooling operation ([C.2]: Operation >
Space heating/cooling), water pipe freeze prevention –
if enabled– will remain active.
NOTICE
Disinfection mode. Even if you turn OFF tank heating
operation ([C.3]: Operation > Tank), disinfection mode will
remain active. However, if you turn it OFF while
disinfection is running, an AH error occurs.
NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO2 equivalent.
Formula to calculate the quantity in CO2 equivalent
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg] / 1000
Please contact your installer for more information.
WARNING
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
WARNING
The refrigerant inside the unit is mildly flammable, but
normally does NOT leak. If the refrigerant leaks in the
room and comes in contact with fire from a burner, a
heater, or a cooker, this may result in fire, or the formation
of a harmful gas.
Turn off any combustible heating devices, ventilate the
room, and contact the dealer where you purchased the
unit.
Do NOT use the unit until a service person confirms that
the part from which the refrigerant leaked has been
repaired.

WARNING
▪ Do NOT pierce or burn refrigerant cycle parts.
▪ Do NOT use cleaning materials or means to accelerate
the defrosting process other than those recommended
by the manufacturer.
▪ Be aware that the refrigerant inside the system is
odourless.
WARNING
Air purging heat emitters or collectors. Before you
purge air from heat emitters or collectors, check if or
is displayed on the home screen of the user interface.
▪ If not, you can purge air immediately.
▪ If yes, make sure that the room where you want to
purge air is sufficiently ventilated. Reason: Refrigerant
might leak into the water circuit, and subsequently into
the room when you purge air from the heat emitters or
collectors.
NOTICE
Do NOT try to dismantle the system yourself: dismantling
of the system, treatment of the refrigerant, oil and other
parts MUST comply with applicable legislation. Units
MUST be treated at a specialised treatment facility for
reuse, recycling and recovery.
3 About the system
Depending on the system layout, the system can:

About space operation modes
Your unit can be a heating or a heating/cooling model:
▪ If your unit is a heating model, it can heat up a space.
▪ If your unit is a heating/cooling model, it can both heat up and cool
down a space. You have to tell the system which operation mode
to use.
To tell the system which space operation to use, you can:
You can… Location
Check which space operation mode is
currently used.

INFORMATION
Risk of space heating capacity shortage for domestic hot
water tank without internal booster heater: In case of
frequent domestic hot water operation, frequent and long
space heating/cooling interruption will happen when
selecting the following:
Tank > Heat up mode > Reheat only.
INFORMATION
When the DHW tank mode is reheat, the risk for capacity
shortage and comfort problem is significant. In case of
frequent reheat operation, space heating/cooling function
is regularly interrupted.
4.5.2 Scheduled mode
In scheduled mode the DHWtank produces hot water corresponding
to a schedule. The best time to allow the tank to produce hot water is
at night, because the space heating demand is lower.

▪ Initially, the DHW tank temperature is the same as the
temperature of the domestic water entering the DHW tank
(example: 15°C).
▪ At 00:00 the DHWtank is programmed to heat up the water to a
preset value (example: Comfort = 60°C).
▪ During the morning, you consume hot water and the DHW tank
temperature decreases.
▪ At 14:00 the DHWtank is programmed to heat up the water to a
preset value (example: Eco = 50°C). Hot water is available again.
▪ During the afternoon and evening, you consume hot water again
and the DHWtank temperature decreases again.
▪ At 00:00 the next day, the cycle repeats.
4.5.3 Scheduled + reheat mode
In scheduled + reheat mode, the domestic hot water control is the
same as in scheduled mode. However, when the DHW tank
temperature drops below a preset value (=reheat tank temperature –
hysteresis value; example: 35°C), the DHW tank heats up until it
reaches the reheat set point (example: 45°C). This ensures that a
minimum amount of hot water is available at all times.
