1.1 General description of the unit
The YLCA/YLHA PLUS 5 to 27 units are high-performance air-water cooling units and heat pumps using
R-410A ecological coolant.
These units are designed for air conditioning or industrial applications that require cold or hot water.
They are silent and compact units, equipped with axial fans, that can be installed directly outdoors.
Inertia tanks are available as an optional extra for those installations requiring a greater volume of water.
The control system of these units is a specially programmed electronic controller for use with air-water
cooling units and heat pumps.
Easy to use and safe, these units precision-control the water return temperature of the installation, carry
out defrost cycles, modulate fan speeds and control compressor, pump and auxiliary electric heater start-
up. By reading the control probes and safety elements, the controller protects the entire equipment
against malfunctions. The system allows connecting the unit to a standard RS485 monitoring network.
