6.5.2 VACATION Mode
To activate the
vacation
function, you need to access the menu and set the number of days
on holiday that you wish, and your equipment will automatically enter
Standby
mode until
the last day of holidays. On the last day, the equipment will begin the
Disinfect
function to
eliminate any formation of germs that appeared in the storage water heater during the time
you were absent. After the holidays and once the program Disinfect is over, the equipment
will resume the mode selected (
ECO
,
AUTO
or
BOOST
).
Note:
If you set your equipment to enter Vacation mode and turn it off with the key ON/OFF,
the function becomes inactive. When you return from your holidays you must remember to
switch on your equipment and cancel the days of holidays introduced (Value=0). If you do
not carry out this operation, your equipment will not restart until the days of holidays selected
have expired.
6.5.3 PV Mode
The PV function offers the possibility to raise the water temperature when an alternative electrical
energy source is available (solar photovoltaic, wind or other), increasing the efficiency of the heat
pump and making the alternative electrical energy source more profitable.
To do this, simply connect a cable from the inverter to the equipment control board. The cable
connection on the control board must be made at the 5V / P2 terminals. Note that this is a dry contact
(no voltage), applying a voltage to this contact can cause irreversible damage to the controller.
When the K1 contact closes, the
PV
function is activated and all active heat sources (Heat Pump +
Electrical Heater) are adjusted to new operating parameters. The compressor will assume the
parameters P01PV / H01PV and the electrical heaters the parameters P02PV / H02PV.
Note:
when contact K1 opens, the equipment assumes the operating mode previously adopted.
Contact K1 can also be used to take advantage of bi-hourly rates. To do this, simply connect a timer
to the 5V / P2 terminals instead of the inverter.
