General description
The YLHA PLUS 5 to 27 units are high-performance air-water
heat pumps using R-410A ecological refrigerant.
These units are designed for air conditioning or industrial ap-
plications that require cold or hot water. They are silent and
compact units, equipped with axial fans, and can be installed
directly outdoors. They are available in two versions: with and
without a hydro kit. Buffer tanks are available for installations
that require a larger water volume.
The control system of these units is a specially programmed
electronic controller to be used on air-water heat pumps.
Easy and safe to use, this control system precision-controls
the water return temperature of the installation, carries out
defrost cycles, modulates fan speeds and controls the com-
pressor, pump and auxiliary electric heater start-ups. By
reading the control probes and safety elements, the control-
ler protects the entire equipment against any malfunctions.
The system allows connecting the unit to a standard RS485
monitoring network. For further information, please see Op-
erating Instructions.
The YLHA PLUS 5 to 27 units are made of proven quality
components and manufactured in compliance with standards
in force (ISO 9001 certification).
