DESCRIPTION OF CONTROL PANEL
The control panel of the unit enables the user to display and set the unit's operating parameters and read the main operating data.
In addition it indicates what mode (cooling or heating) the unit is operating in and signals any alarms that may have been triggered.
Any new settings saved are stored in the card and used the next time the unit is switched on, even following a power failure.
5.1.1
REMOTE CONTROL PANELS (ACCESSORIES)
Installing a PCDS remote control panel enables you to switch the unit on and off and set the operating mode (cooling - heating) from a distance and have a
cumulative alarm indicator (thanks to an alarm signalling relay integrated in the electronic control device).
Installing a PCD remote control panel instead provides remote access to all the electronic control functions installed in the unit.
