For the indoor unit up to size P140, no separate supply line is necessary. The electrical supply and data communication take place via a four-conductor cable from the outdoor to the indoor unit.
•
A line length of up to 120 m can be achieved with the outdoor unit PUHZ-RP200/250YHA2.
Leakage control
Together with the cable remote control PAR-21MAA, the outdoor units of the power inverter Series offer leakage control that is initiated by pushbutton at the remote control. This makes maintenance easier, as the system’s refrigerant level can be checked indirectly and there is no need for the elaborate checking of pipes and junctions.
A-CONTROL
The new A-CONTROL permits direct communication between the indoor and outdoor units. Up to 180 service parameters and fault messages can be conveniently read off the remote control on the indoor unit (Easy Maintenance function, optional). Optionally available with a central control (via Lon Works® or central remote control) at the building management system.
