The unit is designed
for a 2-conductor system.
The system has 2 medium pipes
(conductors: Supply and return
flow) for cooling using a cold
medium or heating using a warm
medium.
In cooling mode the combined
cooling register / heating register
in the indoor unit extracts the heat
from the room air by absorbing it
into the operating medium.
A circulation pump transports the
heated medium to a chiller which
extracts the heat from the medium
in an evaporator and then passes it
on to the outside air via a cooling
cycle in a condenser. The cooled
operating medium is then fed
in once again to the unit medium
circuit.
With 2-conductor systems, which
are used for cooling or heating,
the heating capacity can
be generated through a chiller
with heat pump function
or through a boiler and fed into
the circuit. In heating operation,
the indoor unit can deliver
the heat from the operating
medium to the room air.

Intended use
Depending on the model
and the equipment, the units are
only intended to be used
as a cold water drain to cool
or warm the operating medium
water or a water-glycol mixture
within a closed medium cycle.
Any other use or use in a way
that exceeds the definition above
is considered
non-intended use.
The manufacturer/supplier
assumes no liability for damages
arising from non-intended use.
The user bears the sole risk
in such cases.
Using the equipment as intended
also includes working in accordance
with the operating manual
and installation instructions
and complying with the maintenance
requirements.
