NOTICE

When circulation in each space heating/cooling loop is
controlled by remotely controlled valves, it is important that
the minimum water volume is guaranteed, even if all of the
valves are closed.

Minimum flow rate

Check that the minimum flow rate in the installation is guaranteed in
all conditions. This minimum flow rate is required during defrost/
backup heater operation. For this purpose, use the overpressure
bypass valve delivered with the unit, and respect the minimum water
volume.

Minimum required flow rate

25l/min

NOTICE

To guarantee proper operation it is recommended to have
a minimum flow of 28l/min during DHW.

NOTICE

If glycol was added to the water circuit, and the
temperature of the water circuit is low, the flow rate will
NOT be displayed on the user interface. In this case, the
minimum flow rate can be checked by way of the pump
test (check that the user interface does NOT display error
7H).

NOTICE

When circulation in each or certain space heating loops is
controlled by remotely controlled valves, it is important that
the minimum flow rate is guaranteed, even if all valves are
closed. In case the minimum flow rate cannot be reached,
a flow error 7H will be generated (no heating or operation).

See the installer reference guide for more information.

NOTICE

Make sure both air purge valves (one on the magnetic filter
and one on the backup heater) are open.

All automatic air purge valves must remain open after
commissioning.

4.2.3 To protect the water circuit against freezing

About freeze protection

Frost can damage the system. To prevent the hydraulic components
from freezing, the software is equipped with special frost protection
functions such as water pipe freeze prevention and drain prevention
(see the installer reference guide) that include the activation of pump
in case of low temperatures.

However, in case of a power failure, these functions cannot
guarantee protection.

Do one of the following to protect the water circuit against freezing:

▪ Add glycol to the water. Glycol lowers the freezing point of the

water.

▪ Install freeze protection valves. Freeze protection valves drain the

water from the system before it can freeze.

NOTICE

If you add glycol to the water, do NOT install freeze
protection valves. Possible consequence: Glycol leaking
out of the freeze protection valves.

Freeze protection by glycol

About freeze protection by glycol

Adding glycol to the water lowers the freezing point of water.

WARNING

Ethylene glycol is toxic.

WARNING

Due to the presence of glycol, corrosion of the system is
possible. Uninhibited glycol will turn acidic under the
influence of oxygen. This process is accelerated by the
presence of copper and high temperatures. The acidic
uninhibited glycol attacks metal surfaces and forms
galvanic corrosion cells that cause severe damage to the
system. Therefore it is important that:

▪ the water treatment is correctly executed by a qualified

water specialist,

▪ a glycol with corrosion inhibitors is selected to

counteract acids formed by the oxidation of glycols,

▪ no automotive glycol is used because their corrosion

inhibitors have a limited lifetime and contain silicates
which can foul or plug the system,

▪ galvanized pipes are NOT used in glycol systems since

the presence may lead to the precipitation of certain
components in the glycol's corrosion inhibitor.

NOTICE

Glycol absorbs water from its environment. Therefore do
NOT add glycol that has been exposed to air. Leaving the
cap off the glycol container causes the concentration of
water to increase. The glycol concentration is then lower
than assumed. As a result, the hydraulic components
might freeze up after all. Take preventive actions to ensure
a minimal exposure of the glycol to air.

Types of glycol

The types of glycol that can be used depend on whether the system
contains a domestic hot water tank:

If… Then…

The system contains a domestic

Only use propylene glycol

(a)

hot water tank
The system does NOT contain a

domestic hot water tank

(a)

Propylene glycol, including the necessary inhibitors, classified as
CategoryIII according to EN1717.

You can use either propylene

(a)

glycol

or ethylene glycol

Required concentration of glycol

The required concentration of glycol depends on the lowest
expected outdoor temperature, and on whether you want to protect
the system from bursting or from freezing. To prevent the system
from freezing, more glycol is required.

Add glycol according to the table below.

–20°C 25% —
–25°C 30% —
–30°C 35% —

INFORMATION

▪ Protection against bursting: the glycol will prevent the

piping from bursting, but NOT the liquid inside the
piping from freezing.

▪ Protection against freezing: the glycol will prevent the

liquid inside the piping from freezing.

NOTICE

▪ The required concentration might differ depending on

the type of glycol. ALWAYS compare the requirements
from the table above with the specifications provided by
the glycol manufacturer. If necessary, meet the
requirements set by the glycol manufacturer.

▪ The added concentration of glycol should NEVER

exceed 35%.

▪ If the liquid in the system is frozen, the pump will NOT

be able to start. Mind that if you only prevent the
system from bursting, the liquid inside might still freeze.

▪ When water is at standstill inside the system, the

system is very likely to freeze and get damaged.

Glycol and the maximum allowed water volume

Adding glycol to the water circuit reduces the maximum allowed
water volume of the system. For more information, see the installer
reference guide (topic "To check the water volume and flow rate").

Glycol setting

NOTICE

If glycol is present in the system, setting [E-0D] must be
set to 1. If the glycol setting is NOT set correctly, the liquid
inside the piping can freeze.

Freeze protection by freeze protection valves

About freeze protection valves

When no glycol is added to the water, you can use freeze protection
valves to drain the water from the system before it can freeze.

▪ Install freeze protection valves (field supply) at all lowest points of

the field piping.

▪ Normally closed valves (located indoors near the piping entry/exit

points) can prevent that all water from indoor piping is drained
when the freeze protection valves open.

NOTICE

When freeze protection valves are installed, set the
minimum cooling setpoint (default=7°C) at least 2°C higher
than the maximum opening temperature of the freeze
protection valve. If lower, freeze protection valves can
open during cooling operation.

For more information, see the installer reference guide.

4.2.4 To fill the domestic hot water tank

See the installation manual of the domestic hot water tank.

4.2.5 To insulate the water piping

The piping in the complete water circuit MUST be insulated to
prevent condensation during cooling operation and reduction of the
heating and cooling capacity.

Outdoor water piping insulation

See the installation manual of the outdoor unit, or the installer
reference guide.

DANGER: RISK OF ELECTROCUTION

WARNING

ALWAYS use multicore cable for power supply cables.

INFORMATION

When installing field supply or option cables, foresee
sufficient cable length. This will make it possible to open
the switch box and gain access to other components
during service.

CAUTION

Do NOT push or place redundant cable length in the unit.

NOTICE

The distance between the high voltage and low voltage
cables should be at least 50mm.
